+ /sys/bus/rpmsg/devices/.../name above) and have a local
+ ("source") rpmsg address, and remote ("destination") rpmsg

+
+ A channel is first created when an entity, whether local

+
+ When that happens, a "name service" announcement is sent
+ to the other processor, in order to let it know about the

+ can start sending messages).

+ true or false).

+In the good old days when graphics parameters were configured explicitly
+in a file called xorg.conf, even broken hardware could be managed.
+
+Today, with the advent of Kernel Mode Setting, a graphics board is
+either correctly working because all components follow the standards -
+or the computer is unusable, because the screen remains dark after
+booting or it displays the wrong area. Cases when this happens are:
+- The graphics board does not recognize the monitor.
+- The graphics board is unable to detect any EDID data.
+- The graphics board incorrectly forwards EDID data to the driver.
+- The monitor sends no or bogus EDID data.
+- A KVM sends its own EDID data instead of querying the connected monitor.
+Adding the kernel parameter "nomodeset" helps in most cases, but causes
+restrictions later on.
+
+As a remedy for such situations, the kernel configuration item
+CONFIG_DRM_LOAD_EDID_FIRMWARE was introduced. It allows to provide an
+individually prepared or corrected EDID data set in the /lib/firmware
+directory from where it is loaded via the firmware interface. The code
+(see drivers/gpu/drm/drm_edid_load.c) contains built-in data sets for
+commonly used screen resolutions (1024x768, 1280x1024, 1680x1050,
+1920x1080) as binary blobs, but the kernel source tree does not contain
+code to create these data. In order to elucidate the origin of the
+built-in binary EDID blobs and to facilitate the creation of individual
+data for a specific misbehaving monitor, commented sources and a
+Makefile environment are given here.
+
+To create binary EDID and C source code files from the existing data
+material, simply type "make".
+
+If you want to create your own EDID file, copy the file 1024x768.S and
+replace the settings with your own data. The CRC value in the last line
+ #define CRC 0x55
+is a bit tricky. After a first version of the binary data set is
+created, it must be be checked with the "edid-decode" utility which will

+irq_domain interrupt number mapping library
+
+The current design of the Linux kernel uses a single large number
+space where each separate IRQ source is assigned a different number.
+This is simple when there is only one interrupt controller, but in
+systems with multiple interrupt controllers the kernel must ensure
+that each one gets assigned non-overlapping allocations of Linux
+IRQ numbers.
+
+The irq_alloc_desc*() and irq_free_desc*() APIs provide allocation of
+irq numbers, but they don't provide any support for reverse mapping of
+the controller-local IRQ (hwirq) number into the Linux IRQ number
+space.
+
+The irq_domain library adds mapping between hwirq and IRQ numbers on
+top of the irq_alloc_desc*() API. An irq_domain to manage mapping is
+preferred over interrupt controller drivers open coding their own
+reverse mapping scheme.
+
+irq_domain also implements translation from Device Tree interrupt
+specifiers to hwirq numbers, and can be easily extended to support
+other IRQ topology data sources.
+
+=== irq_domain usage ===
+An interrupt controller driver creates and registers an irq_domain by
+calling one of the irq_domain_add_*() functions (each mapping method
+has a different allocator function, more on that later). The function
+will return a pointer to the irq_domain on success. The caller must
+provide the allocator function with an irq_domain_ops structure with
+the .map callback populated as a minimum.
+
+In most cases, the irq_domain will begin empty without any mappings
+between hwirq and IRQ numbers. Mappings are added to the irq_domain
+by calling irq_create_mapping() which accepts the irq_domain and a
+hwirq number as arguments. If a mapping for the hwirq doesn't already
+exist then it will allocate a new Linux irq_desc, associate it with
+the hwirq, and call the .map() callback so the driver can perform any
+required hardware setup.
+
+When an interrupt is received, irq_find_mapping() function should
+be used to find the Linux IRQ number from the hwirq number.
+
+If the driver has the Linux IRQ number or the irq_data pointer, and
+needs to know the associated hwirq number (such as in the irq_chip
+callbacks) then it can be directly obtained from irq_data->hwirq.
+
+=== Types of irq_domain mappings ===
+There are several mechanisms available for reverse mapping from hwirq
+to Linux irq, and each mechanism uses a different allocation function.
+Which reverse map type should be used depends on the use case. Each
+of the reverse map types are described below:
+
+==== Linear ====
+irq_domain_add_linear()
+
+The linear reverse map maintains a fixed size table indexed by the
+hwirq number. When a hwirq is mapped, an irq_desc is allocated for
+the hwirq, and the IRQ number is stored in the table.
+
+The Linear map is a good choice when the maximum number of hwirqs is
+fixed and a relatively small number (~ < 256). The advantages of this
+map are fixed time lookup for IRQ numbers, and irq_descs are only
+allocated for in-use IRQs. The disadvantage is that the table must be
+as large as the largest possible hwirq number.
+
+The majority of drivers should use the linear map.
+
+==== Tree ====
+irq_domain_add_tree()
+
+The irq_domain maintains a radix tree map from hwirq numbers to Linux
+IRQs. When an hwirq is mapped, an irq_desc is allocated and the
+hwirq is used as the lookup key for the radix tree.
+
+The tree map is a good choice if the hwirq number can be very large
+since it doesn't need to allocate a table as large as the largest
+hwirq number. The disadvantage is that hwirq to IRQ number lookup is
+dependent on how many entries are in the table.
+
+Very few drivers should need this mapping. At the moment, powerpc
+iseries is the only user.
+
+==== No Map ===-
+irq_domain_add_nomap()
+
+The No Map mapping is to be used when the hwirq number is
+programmable in the hardware. In this case it is best to program the
+Linux IRQ number into the hardware itself so that no mapping is
+required. Calling irq_create_direct_mapping() will allocate a Linux
+IRQ number and call the .map() callback so that driver can program the
+Linux IRQ number into the hardware.
+
+Most drivers cannot use this mapping.
+
+==== Legacy ====
+irq_domain_add_legacy()
+irq_domain_add_legacy_isa()
+
+The Legacy mapping is a special case for drivers that already have a
+range of irq_descs allocated for the hwirqs. It is used when the
+driver cannot be immediately converted to use the linear mapping. For
+example, many embedded system board support files use a set of #defines
+for IRQ numbers that are passed to struct device registrations. In that
+case the Linux IRQ numbers cannot be dynamically assigned and the legacy
+mapping should be used.
+
+The legacy map assumes a contiguous range of IRQ numbers has already
+been allocated for the controller and that the IRQ number can be
+calculated by adding a fixed offset to the hwirq number, and
+visa-versa. The disadvantage is that it requires the interrupt
+controller to manage IRQ allocations and it requires an irq_desc to be
+allocated for every hwirq, even if it is unused.
+
+The legacy map should only be used if fixed IRQ mappings must be
+supported. For example, ISA controllers would use the legacy map for
+mapping Linux IRQs 0-15 so that existing ISA drivers get the correct IRQ
+numbers.

This is rare, but does happen from time to time in real life.
+If the CONFIG_RCU_CPU_STALL_INFO kernel configuration parameter is set,
+more information is printed with the stall-warning message, for example:
+
+ INFO: rcu_preempt detected stall on CPU
+ 0: (63959 ticks this GP) idle=241/3fffffffffffffff/0
+ (t=65000 jiffies)
+
+In kernels with CONFIG_RCU_FAST_NO_HZ, even more information is

+
+ INFO: rcu_preempt detected stall on CPU
+ 0: (64628 ticks this GP) idle=dd5/3fffffffffffffff/0 drain=0 . timer=-1
+ (t=65000 jiffies)
+
+The "(64628 ticks this GP)" indicates that this CPU has taken more
+than 64,000 scheduling-clock interrupts during the current stalled
+grace period. If the CPU was not yet aware of the current grace
+period (for example, if it was offline), then this part of the message
+indicates how many grace periods behind the CPU is.
+
+The "idle=" portion of the message prints the dyntick-idle state.
+The hex number before the first "/" is the low-order 12 bits of the
+dynticks counter, which will have an even-numbered value if the CPU is
+in dyntick-idle mode and an odd-numbered value otherwise. The hex
+number between the two "/"s is the value of the nesting, which will
+be a small positive number if in the idle loop and a very large positive
+number (as shown above) otherwise.
+
+For CONFIG_RCU_FAST_NO_HZ kernels, the "drain=0" indicates that the
+CPU is not in the process of trying to force itself into dyntick-idle
+state, the "." indicates that the CPU has not given up forcing RCU
+into dyntick-idle mode (it would be "H" otherwise), and the "timer=-1"
+indicates that the CPU has not recented forced RCU into dyntick-idle
+mode (it would otherwise indicate the number of microseconds remaining
+in this forced state).
+
+
+Multiple Warnings From One Stall
+
+If a stall lasts long enough, multiple stall-warning messages will be
+printed for it. The second and subsequent messages are printed at
+longer intervals, so that the time between (say) the first and second
+message will be about three times the interval between the beginning
+of the stall and the first message.

+Supported chips:
+ Texas Instruments LP8550, LP8551, LP8552, LP8553 and LP8556
+
+Author: Milo(Woogyom) Kim <milo.kim@ti.com>

+Description
+-----------
+
+* Brightness control
+
+Brightness can be controlled by the pwm input or the i2c command.
+The lp855x driver supports both cases.
+
+* Device attributes
+
+1) bl_ctl_mode
+Backlight control mode.
+Value : pwm based or register based
+
+2) chip_id

+
+Platform data for lp855x
+------------------------
+
+For supporting platform specific data, the lp855x platform data can be used.
+
+* name : Backlight driver name. If it is not defined, default name is set.
+* mode : Brightness control mode. PWM or register based.
+* device_control : Value of DEVICE CONTROL register.
+* initial_brightness : Initial value of backlight brightness.
+* pwm_data : Platform specific pwm generation functions.
+ Only valid when brightness is pwm input mode.
+ Functions should be implemented by PWM driver.
+ - pwm_set_intensity() : set duty of PWM
+ - pwm_get_intensity() : get current duty of PWM
+* load_new_rom_data :
+ 0 : use default configuration data
+ 1 : update values of eeprom or eprom registers on loading driver
+* size_program : Total size of lp855x_rom_data.
+* rom_data : List of new eeprom/eprom registers.
+
+example 1) lp8552 platform data : i2c register mode with new eeprom data

+CRC matches the recomputed value, *or* you can check that the
+remainder computed on the message+CRC is 0. This latter approach
+is used by a lot of hardware implementations, and is why so many
+protocols put the end-of-frame flag after the CRC.
+
+It's actually the same long division you learned in school, except that
+- We're working in binary, so the digits are only 0 and 1, and
+- When dividing polynomials, there are no carries. Rather than add and
+ subtract, we just xor. Thus, we tend to get a bit sloppy about
+ the difference between adding and subtracting.
+
+Like all division, the remainder is always smaller than the divisor.
+To produce a 32-bit CRC, the divisor is actually a 33-bit CRC polynomial.
+Since it's 33 bits long, bit 32 is always going to be set, so usually the
+CRC is written in hex with the most significant bit omitted. (If you're
+familiar with the IEEE 754 floating-point format, it's the same idea.)
+
+Note that a CRC is computed over a string of *bits*, so you have
+to decide on the endianness of the bits within each byte. To get
+the best error-detecting properties, this should correspond to the
+order they're actually sent. For example, standard RS-232 serial is
+little-endian; the most significant bit (sometimes used for parity)
+is sent last. And when appending a CRC word to a message, you should
+do it in the right order, matching the endianness.
+
+Just like with ordinary division, you proceed one digit (bit) at a time.
+Each step of the division you take one more digit (bit) of the dividend
+and append it to the current remainder. Then you figure out the
+appropriate multiple of the divisor to subtract to being the remainder
+back into range. In binary, this is easy - it has to be either 0 or 1,
+and to make the XOR cancel, it's just a copy of bit 32 of the remainder.
+
+When computing a CRC, we don't care about the quotient, so we can
+throw the quotient bit away, but subtract the appropriate multiple of
+the polynomial from the remainder and we're back to where we started,
+ready to process the next bit.
+
+A big-endian CRC written this way would be coded like:
+for (i = 0; i < input_bits; i++) {
+ multiple = remainder & 0x80000000 ? CRCPOLY : 0;
+ remainder = (remainder << 1 | next_input_bit()) ^ multiple;
+}
+
+Notice how, to get at bit 32 of the shifted remainder, we look
+at bit 31 of the remainder *before* shifting it.
+
+But also notice how the next_input_bit() bits we're shifting into
+the remainder don't actually affect any decision-making until
+32 bits later. Thus, the first 32 cycles of this are pretty boring.
+Also, to add the CRC to a message, we need a 32-bit-long hole for it at
+the end, so we have to add 32 extra cycles shifting in zeros at the
+end of every message,
+
+These details lead to a standard trick: rearrange merging in the
+next_input_bit() until the moment it's needed. Then the first 32 cycles
+can be precomputed, and merging in the final 32 zero bits to make room
+for the CRC can be skipped entirely. This changes the code to:
+
+for (i = 0; i < input_bits; i++) {
+ remainder ^= next_input_bit() << 31;
+ multiple = (remainder & 0x80000000) ? CRCPOLY : 0;
+ remainder = (remainder << 1) ^ multiple;
+}
+
+With this optimization, the little-endian code is particularly simple:
+for (i = 0; i < input_bits; i++) {
+ remainder ^= next_input_bit();
+ multiple = (remainder & 1) ? CRCPOLY : 0;
+ remainder = (remainder >> 1) ^ multiple;
+}
+
+The most significant coefficient of the remainder polynomial is stored
+in the least significant bit of the binary "remainder" variable.
+The other details of endianness have been hidden in CRCPOLY (which must
+be bit-reversed) and next_input_bit().
+
+As long as next_input_bit is returning the bits in a sensible order, we don't
+*have* to wait until the last possible moment to merge in additional bits.
+We can do it 8 bits at a time rather than 1 bit at a time:
+for (i = 0; i < input_bytes; i++) {
+ remainder ^= next_input_byte() << 24;
+ for (j = 0; j < 8; j++) {
+ multiple = (remainder & 0x80000000) ? CRCPOLY : 0;
+ remainder = (remainder << 1) ^ multiple;
+ }
+}
+
+Or in little-endian:
+for (i = 0; i < input_bytes; i++) {
+ remainder ^= next_input_byte();
+ for (j = 0; j < 8; j++) {
+ multiple = (remainder & 1) ? CRCPOLY : 0;
+ remainder = (remainder >> 1) ^ multiple;
+ }
+}
+
+If the input is a multiple of 32 bits, you can even XOR in a 32-bit
+word at a time and increase the inner loop count to 32.
+
+You can also mix and match the two loop styles, for example doing the
+bulk of a message byte-at-a-time and adding bit-at-a-time processing
+for any fractional bytes at the end.
+
+To reduce the number of conditional branches, software commonly uses
+the byte-at-a-time table method, popularized by Dilip V. Sarwate,
+"Computation of Cyclic Redundancy Checks via Table Look-Up", Comm. ACM
+v.31 no.8 (August 1998) p. 1008-1013.
+
+Here, rather than just shifting one bit of the remainder to decide
+in the correct multiple to subtract, we can shift a byte at a time.
+This produces a 40-bit (rather than a 33-bit) intermediate remainder,
+and the correct multiple of the polynomial to subtract is found using
+a 256-entry lookup table indexed by the high 8 bits.
+
+(The table entries are simply the CRC-32 of the given one-byte messages.)
+
+When space is more constrained, smaller tables can be used, e.g. two
+4-bit shifts followed by a lookup in a 16-entry table.
+
+It is not practical to process much more than 8 bits at a time using this
+technique, because tables larger than 256 entries use too much memory and,
+more importantly, too much of the L1 cache.
+
+To get higher software performance, a "slicing" technique can be used.
+See "High Octane CRC Generation with the Intel Slicing-by-8 Algorithm",
+ftp://download.intel.com/technology/comms/perfnet/download/slicing-by-8.pdf
+
+This does not change the number of table lookups, but does increase
+the parallelism. With the classic Sarwate algorithm, each table lookup
+must be completed before the index of the next can be computed.
+
+A "slicing by 2" technique would shift the remainder 16 bits at a time,
+producing a 48-bit intermediate remainder. Rather than doing a single
+lookup in a 65536-entry table, the two high bytes are looked up in
+two different 256-entry tables. Each contains the remainder required
+to cancel out the corresponding byte. The tables are different because the
+polynomials to cancel are different. One has non-zero coefficients from
+x^32 to x^39, while the other goes from x^40 to x^47.
+
+Since modern processors can handle many parallel memory operations, this
+takes barely longer than a single table look-up and thus performs almost
+twice as fast as the basic Sarwate algorithm.
+
+This can be extended to "slicing by 4" using 4 256-entry tables.
+Each step, 32 bits of data is fetched, XORed with the CRC, and the result
+broken into bytes and looked up in the tables. Because the 32-bit shift
+leaves the low-order bits of the intermediate remainder zero, the
+final CRC is simply the XOR of the 4 table look-ups.
+
+But this still enforces sequential execution: a second group of table
+look-ups cannot begin until the previous groups 4 table look-ups have all
+been completed. Thus, the processor's load/store unit is sometimes idle.
+
+To make maximum use of the processor, "slicing by 8" performs 8 look-ups
+in parallel. Each step, the 32-bit CRC is shifted 64 bits and XORed
+with 64 bits of input data. What is important to note is that 4 of
+those 8 bytes are simply copies of the input data; they do not depend
+on the previous CRC at all. Thus, those 4 table look-ups may commence
+immediately, without waiting for the previous loop iteration.
+
+By always having 4 loads in flight, a modern superscalar processor can
+be kept busy and make full use of its L1 cache.
+
+Two more details about CRC implementation in the real world:
+
+Normally, appending zero bits to a message which is already a multiple
+of a polynomial produces a larger multiple of that polynomial. Thus,
+a basic CRC will not detect appended zero bits (or bytes). To enable
+a CRC to detect this condition, it's common to invert the CRC before
+appending it. This makes the remainder of the message+crc come out not
+as zero, but some fixed non-zero value. (The CRC of the inversion
+pattern, 0xffffffff.)
+
+The same problem applies to zero bits prepended to the message, and a
+similar solution is used. Instead of starting the CRC computation with
+a remainder of 0, an initial remainder of all ones is used. As long as
+you start the same way on decoding, it doesn't make a difference.

+* ARM Timer Watchdog
+
+ARM 11MP, Cortex-A5 and Cortex-A9 are often associated with a per-core
+Timer-Watchdog (aka TWD), which provides both a per-cpu local timer
+and watchdog.
+
+The TWD is usually attached to a GIC to deliver its two per-processor
+interrupts.
+
+** Timer node required properties:
+
+- compatible : Should be one of:
+ "arm,cortex-a9-twd-timer"
+ "arm,cortex-a5-twd-timer"
+ "arm,arm11mp-twd-timer"
+
+- interrupts : One interrupt to each core
+
+- reg : Specify the base address and the size of the TWD timer
+ register window.
+
+Example:
+
+ twd-timer@2c000600 {
+ compatible = "arm,arm11mp-twd-timer"";
+ reg = <0x2c000600 0x20>;
+ interrupts = <1 13 0xf01>;

+ARM Versatile Express boards family
+-----------------------------------
+
+ARM's Versatile Express platform consists of a motherboard and one
+or more daughterboards (tiles). The motherboard provides a set of
+peripherals. Processor and RAM "live" on the tiles.
+
+The motherboard and each core tile should be described by a separate
+Device Tree source file, with the tile's description including
+the motherboard file using a /include/ directive. As the motherboard
+can be initialized in one of two different configurations ("memory
+maps"), care must be taken to include the correct one.
+
+Required properties in the root node:
+- compatible value:
+ compatible = "arm,vexpress,<model>", "arm,vexpress";
+ where <model> is the full tile model name (as used in the tile's
+ Technical Reference Manual), eg.:
+ - for Coretile Express A5x2 (V2P-CA5s):
+ compatible = "arm,vexpress,v2p-ca5s", "arm,vexpress";
+ - for Coretile Express A9x4 (V2P-CA9):
+ compatible = "arm,vexpress,v2p-ca9", "arm,vexpress";
+ If a tile comes in several variants or can be used in more then one
+ configuration, the compatible value should be:
+ compatible = "arm,vexpress,<model>,<variant>", \
+ "arm,vexpress,<model>", "arm,vexpress";
+ eg:
+ - Coretile Express A15x2 (V2P-CA15) with Tech Chip 1:
+ compatible = "arm,vexpress,v2p-ca15,tc1", \
+ "arm,vexpress,v2p-ca15", "arm,vexpress";
+ - LogicTile Express 13MG (V2F-2XV6) running Cortex-A7 (3 cores) SMM:
+ compatible = "arm,vexpress,v2f-2xv6,ca7x3", \
+ "arm,vexpress,v2f-2xv6", "arm,vexpress";
+
+Optional properties in the root node:
+- tile model name (use name from the tile's Technical Reference
+ Manual, eg. "V2P-CA5s")
+ model = "<model>";
+- tile's HBI number (unique ARM's board model ID, visible on the
+ PCB's silkscreen) in hexadecimal transcription:
+ arm,hbi = <0xhbi>
+ eg:
+ - for Coretile Express A5x2 (V2P-CA5s) HBI-0191:
+ arm,hbi = <0x191>;
+ - Coretile Express A9x4 (V2P-CA9) HBI-0225:
+ arm,hbi = <0x225>;
+
+Top-level standard "cpus" node is required. It must contain a node
+with device_type = "cpu" property for every available core, eg.:
+
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ cpu@0 {
+ device_type = "cpu";
+ compatible = "arm,cortex-a5";
+ reg = <0>;
+ };
+ };
+
+The motherboard description file provides a single "motherboard" node
+using 2 address cells corresponding to the Static Memory Bus used
+between the motherboard and the tile. The first cell defines the Chip
+Select (CS) line number, the second cell address offset within the CS.
+All interrupt lines between the motherboard and the tile are active
+high and are described using single cell.
+
+Optional properties of the "motherboard" node:
+- motherboard's memory map variant:
+ arm,v2m-memory-map = "<name>";
+ where name is one of:
+ - "rs1" - for RS1 map (i.a. peripherals on CS3); this map is also
+ referred to as "ARM Cortex-A Series memory map":
+ arm,v2m-memory-map = "rs1";
+ When this property is missing, the motherboard is using the original
+ memory map (also known as the "Legacy memory map", primarily used
+ with the original CoreTile Express A9x4) with peripherals on CS7.
+
+Motherboard .dtsi files provide a set of labelled peripherals that
+can be used to obtain required phandle in the tile's "aliases" node:
+- UARTs, note that the numbers correspond to the physical connectors
+ on the motherboard's back panel:
+ v2m_serial0, v2m_serial1, v2m_serial2 and v2m_serial3
+- I2C controllers:
+ v2m_i2c_dvi and v2m_i2c_pcie
+- SP804 timers:
+ v2m_timer01 and v2m_timer23
+
+Current Linux implementation requires a "arm,v2m_timer" alias
+pointing at one of the motherboard's SP804 timers, if it is to be
+used as the system timer. This alias should be defined in the
+motherboard files.
+
+The tile description must define "ranges", "interrupt-map-mask" and
+"interrupt-map" properties to translate the motherboard's address
+and interrupt space into one used by the tile's processor.
+
+Abbreviated example:
+
+/dts-v1/;
+
+/ {
+ model = "V2P-CA5s";
+ arm,hbi = <0x225>;
+ compatible = "arm,vexpress-v2p-ca5s", "arm,vexpress";
+ interrupt-parent = <&gic>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ chosen { };
+
+ aliases {
+ serial0 = &v2m_serial0;
+ };
+
+ cpus {
+ #address-cells = <1>;

+* FSL MPIC Message Registers
+
+This binding specifies what properties must be available in the device tree
+representation of the message register blocks found in some FSL MPIC
+implementations.
+
+Required properties:
+
+ - compatible: Specifies the compatibility list for the message register
+ block. The type shall be <string-list> and the value shall be of the form
+ "fsl,mpic-v<version>-msgr", where <version> is the version number of
+ the MPIC containing the message registers.
+
+ - reg: Specifies the base physical address(s) and size(s) of the
+ message register block's addressable register space. The type shall be
+ <prop-encoded-array>.
+
+ - interrupts: Specifies a list of interrupt-specifiers which are available
+ for receiving interrupts. Interrupt-specifier consists of two cells: first
+ cell is interrupt-number and second cell is level-sense. The type shall be
+ <prop-encoded-array>.
+
+Optional properties:
+
+ - mpic-msgr-receive-mask: Specifies what registers in the containing block
+ are allowed to receive interrupts. The value is a bit mask where a set
+ bit at bit 'n' indicates that message register 'n' can receive interrupts.
+ Note that "bit 'n'" is numbered from LSB for PPC hardware. The type shall
+ be <u32>. If not present, then all of the message registers in the block
+ are available.

+ required, though. However, a particular implementation of this binding
+ may require aliases to be present. Aliases are of the form

+layout drivers
+--------------
+
+PNFS utilizes what is called layout drivers. The STD defines 3 basic
+layout types: "files" "objects" and "blocks". For each of these types
+there is a layout-driver with a common function-vectors table which
+are called by the nfs-client pnfs-core to implement the different layout
+types.
+
+Files-layout-driver code is in: fs/nfs/nfs4filelayout.c && nfs4filelayoutdev.c
+Objects-layout-deriver code is in: fs/nfs/objlayout/.. directory
+Blocks-layout-deriver code is in: fs/nfs/blocklayout/.. directory
+
+objects-layout setup
+--------------------
+
+As part of the full STD implementation the objlayoutdriver.ko needs, at times,
+to automatically login to yet undiscovered iscsi/osd devices. For this the
+driver makes up-calles to a user-mode script called *osd_login*
+
+The path_name of the script to use is by default:
+ /sbin/osd_login.
+This name can be overridden by the Kernel module parameter:
+ objlayoutdriver.osd_login_prog
+
+If Kernel does not find the osd_login_prog path it will zero it out
+and will not attempt farther logins. An admin can then write new value
+to the objlayoutdriver.osd_login_prog Kernel parameter to re-enable it.
+
+The /sbin/osd_login is part of the nfs-utils package, and should usually
+be installed on distributions that support this Kernel version.
+
+The API to the login script is as follows:
+ Usage: $0 -u <URI> -o <OSDNAME> -s <SYSTEMID>
+ Options:
+ -u target uri e.g. iscsi://<ip>:<port>
+ (allways exists)
+ (More protocols can be defined in the future.
+ The client does not interpret this string it is
+ passed unchanged as recieved from the Server)
+ -o osdname of the requested target OSD
+ (Might be empty)
+ (A string which denotes the OSD name, there is a
+ limit of 64 chars on this string)
+ -s systemid of the requested target OSD
+ (Might be empty)
+ (This string, if not empty is always an hex
+ representation of the 20 bytes osd_system_id)

+The QNX6 Filesystem
+===================
+
+The qnx6fs is used by newer QNX operating system versions. (e.g. Neutrino)
+It got introduced in QNX 6.4.0 and is used default since 6.4.1.
+
+Option
+======
+
+mmi_fs Mount filesystem as used for example by Audi MMI 3G system
+
+Specification
+=============
+
+qnx6fs shares many properties with traditional Unix filesystems. It has the
+concepts of blocks, inodes and directories.
+On QNX it is possible to create little endian and big endian qnx6 filesystems.
+This feature makes it possible to create and use a different endianness fs
+for the target (QNX is used on quite a range of embedded systems) plattform
+running on a different endianess.
+The Linux driver handles endianness transparently. (LE and BE)
+
+Blocks
+------
+
+The space in the device or file is split up into blocks. These are a fixed
+size of 512, 1024, 2048 or 4096, which is decided when the filesystem is
+created.
+Blockpointers are 32bit, so the maximum space that can be adressed is
+2^32 * 4096 bytes or 16TB
+
+The superblocks
+---------------
+
+The superblock contains all global information about the filesystem.
+Each qnx6fs got two superblocks, each one having a 64bit serial number.
+That serial number is used to identify the "active" superblock.
+In write mode with reach new snapshot (after each synchronous write), the
+serial of the new master superblock is increased (old superblock serial + 1)
+
+So basically the snapshot functionality is realized by an atomic final
+update of the serial number. Before updating that serial, all modifications
+are done by copying all modified blocks during that specific write request
+(or period) and building up a new (stable) filesystem structure under the
+inactive superblock.
+
+Each superblock holds a set of root inodes for the different filesystem
+parts. (Inode, Bitmap and Longfilenames)
+Each of these root nodes holds information like total size of the stored
+data and the adressing levels in that specific tree.
+If the level value is 0, up to 16 direct blocks can be adressed by each
+node.
+Level 1 adds an additional indirect adressing level where each indirect
+adressing block holds up to blocksize / 4 bytes pointers to data blocks.
+Level 2 adds an additional indirect adressig block level (so, already up
+to 16 * 256 * 256 = 1048576 blocks that can be adressed by such a tree)a
+
+Unused block pointers are always set to ~0 - regardless of root node,
+indirect adressing blocks or inodes.
+Data leaves are always on the lowest level. So no data is stored on upper
+tree levels.
+
+The first Superblock is located at 0x2000. (0x2000 is the bootblock size)
+The Audi MMI 3G first superblock directly starts at byte 0.
+Second superblock position can either be calculated from the superblock
+information (total number of filesystem blocks) or by taking the highest
+device address, zeroing the last 3 bytes and then substracting 0x1000 from
+that address.
+
+0x1000 is the size reserved for each superblock - regardless of the
+blocksize of the filesystem.
+
+Inodes
+------
+
+Each object in the filesystem is represented by an inode. (index node)
+The inode structure contains pointers to the filesystem blocks which contain
+the data held in the object and all of the metadata about an object except
+its longname. (filenames longer than 27 characters)
+The metadata about an object includes the permissions, owner, group, flags,
+size, number of blocks used, access time, change time and modification time.
+
+Object mode field is POSIX format. (which makes things easier)
+
+There are also pointers to the first 16 blocks, if the object data can be
+adressed with 16 direct blocks.
+For more than 16 blocks an indirect adressing in form of another tree is
+used. (scheme is the same as the one used for the superblock root nodes)
+
+The filesize is stored 64bit. Inode counting starts with 1. (whilst long
+filename inodes start with 0)
+
+Directories
+-----------
+
+A directory is a filesystem object and has an inode just like a file.
+It is a specially formatted file containing records which associate each
+name with an inode number.
+'.' inode number points to the directory inode
+'..' inode number points to the parent directory inode
+Eeach filename record additionally got a filename length field.
+
+One special case are long filenames or subdirectory names.
+These got set a filename length field of 0xff in the corresponding directory
+record plus the longfile inode number also stored in that record.
+With that longfilename inode number, the longfilename tree can be walked
+starting with the superblock longfilename root node pointers.
+
+Special files
+-------------
+
+Symbolic links are also filesystem objects with inodes. They got a specific
+bit in the inode mode field identifying them as symbolic link.
+The directory entry file inode pointer points to the target file inode.
+
+Hard links got an inode, a directory entry, but a specific mode bit set,
+no block pointers and the directory file record pointing to the target file
+inode.
+
+Character and block special devices do not exist in QNX as those files
+are handled by the QNX kernel/drivers and created in /dev independant of the
+underlaying filesystem.
+
+Long filenames
+--------------
+
+Long filenames are stored in a seperate adressing tree. The staring point
+is the longfilename root node in the active superblock.
+Each data block (tree leaves) holds one long filename. That filename is
+limited to 510 bytes. The first two starting bytes are used as length field
+for the actual filename.
+If that structure shall fit for all allowed blocksizes, it is clear why there
+is a limit of 510 bytes for the actual filename stored.
+
+Bitmap
+------
+
+The qnx6fs filesystem allocation bitmap is stored in a tree under bitmap
+root node in the superblock and each bit in the bitmap represents one
+filesystem block.
+The first block is block 0, which starts 0x1000 after superblock start.
+So for a normal qnx6fs 0x3000 (bootblock + superblock) is the physical
+address at which block 0 is located.
+
+Bits at the end of the last bitmap block are set to 1, if the device is
+smaller than addressing space in the bitmap.
+
+Bitmap system area
+------------------
+
+The bitmap itself is devided into three parts.
+First the system area, that is split into two halfs.
+Then userspace.
+
+The requirement for a static, fixed preallocated system area comes from how
+qnx6fs deals with writes.
+Each superblock got it's own half of the system area. So superblock #1
+always uses blocks from the lower half whilst superblock #2 just writes to
+blocks represented by the upper half bitmap system area bits.
+
+Bitmap blocks, Inode blocks and indirect addressing blocks for those two
+tree structures are treated as system blocks.
+
+The rational behind that is that a write request can work on a new snapshot
+(system area of the inactive - resp. lower serial numbered superblock) while
+at the same time there is still a complete stable filesystem structer in the
+other half of the system area.
+
+When finished with writing (a sync write is completed, the maximum sync leap
+time or a filesystem sync is requested), serial of the previously inactive
+superblock atomically is increased and the fs switches over to that - then
+stable declared - superblock.
+
+For all data outside the system area, blocks are just copied while writing.

+===============================================================
+Softlockup detector and hardlockup detector (aka nmi_watchdog)
+===============================================================
+
+The Linux kernel can act as a watchdog to detect both soft and hard
+lockups.
+
+A 'softlockup' is defined as a bug that causes the kernel to loop in
+kernel mode for more than 20 seconds (see "Implementation" below for
+details), without giving other tasks a chance to run. The current
+stack trace is displayed upon detection and, by default, the system
+will stay locked up. Alternatively, the kernel can be configured to
+panic; a sysctl, "kernel.softlockup_panic", a kernel parameter,
+"softlockup_panic" (see "Documentation/kernel-parameters.txt" for
+details), and a compile option, "BOOTPARAM_HARDLOCKUP_PANIC", are
+provided for this.
+
+A 'hardlockup' is defined as a bug that causes the CPU to loop in
+kernel mode for more than 10 seconds (see "Implementation" below for
+details), without letting other interrupts have a chance to run.
+Similarly to the softlockup case, the current stack trace is displayed
+upon detection and the system will stay locked up unless the default
+behavior is changed, which can be done through a compile time knob,
+"BOOTPARAM_HARDLOCKUP_PANIC", and a kernel parameter, "nmi_watchdog"
+(see "Documentation/kernel-parameters.txt" for details).
+
+The panic option can be used in combination with panic_timeout (this
+timeout is set through the confusingly named "kernel.panic" sysctl),
+to cause the system to reboot automatically after a specified amount
+of time.
+
+=== Implementation ===
+
+The soft and hard lockup detectors are built on top of the hrtimer and
+perf subsystems, respectively. A direct consequence of this is that,
+in principle, they should work in any architecture where these
+subsystems are present.
+
+A periodic hrtimer runs to generate interrupts and kick the watchdog
+task. An NMI perf event is generated every "watchdog_thresh"
+(compile-time initialized to 10 and configurable through sysctl of the
+same name) seconds to check for hardlockups. If any CPU in the system
+does not receive any hrtimer interrupt during that time the
+'hardlockup detector' (the handler for the NMI perf event) will
+generate a kernel warning or call panic, depending on the
+configuration.
+
+The watchdog task is a high priority kernel thread that updates a
+timestamp every time it is scheduled. If that timestamp is not updated
+for 2*watchdog_thresh seconds (the softlockup threshold) the
+'softlockup detector' (coded inside the hrtimer callback function)
+will dump useful debug information to the system log, after which it
+will call panic if it was instructed to do so or resume execution of
+other kernel code.
+
+The period of the hrtimer is 2*watchdog_thresh/5, which means it has
+two or three chances to generate an interrupt before the hardlockup
+detector kicks in.
+
+As explained above, a kernel knob is provided that allows
+administrators to configure the period of the hrtimer and the perf
+event. The right value for a particular environment is a trade-off
+between fast response to lockups and detection overhead.

+General Public License applies to most of the Free Software

+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+ When we speak of free software, we are referring to freedom, not

+have the freedom to distribute copies of free software (and charge for

+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their

+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,

+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.

+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.

-[NMI watchdog is available for x86 and x86-64 architectures]
-
-Is your system locking up unpredictably? No keyboard activity, just
-a frustrating complete hard lockup? Do you want to help us debugging
-such lockups? If all yes then this document is definitely for you.
-
-On many x86/x86-64 type hardware there is a feature that enables
-us to generate 'watchdog NMI interrupts'. (NMI: Non Maskable Interrupt
-which get executed even if the system is otherwise locked up hard).
-This can be used to debug hard kernel lockups. By executing periodic
-NMI interrupts, the kernel can monitor whether any CPU has locked up,
-and print out debugging messages if so.
-
-In order to use the NMI watchdog, you need to have APIC support in your
-kernel. For SMP kernels, APIC support gets compiled in automatically. For
-UP, enable either CONFIG_X86_UP_APIC (Processor type and features -> Local
-APIC support on uniprocessors) or CONFIG_X86_UP_IOAPIC (Processor type and
-features -> IO-APIC support on uniprocessors) in your kernel config.
-CONFIG_X86_UP_APIC is for uniprocessor machines without an IO-APIC.
-CONFIG_X86_UP_IOAPIC is for uniprocessor with an IO-APIC. [Note: certain
-kernel debugging options, such as Kernel Stack Meter or Kernel Tracer,
-may implicitly disable the NMI watchdog.]
-
-For x86-64, the needed APIC is always compiled in.
-
-Using local APIC (nmi_watchdog=2) needs the first performance register, so
-you can't use it for other purposes (such as high precision performance
-profiling.) However, at least oprofile and the perfctr driver disable the
-local APIC NMI watchdog automatically.
-
-To actually enable the NMI watchdog, use the 'nmi_watchdog=N' boot
-parameter. Eg. the relevant lilo.conf entry:
-
- append="nmi_watchdog=1"
-
-For SMP machines and UP machines with an IO-APIC use nmi_watchdog=1.
-For UP machines without an IO-APIC use nmi_watchdog=2, this only works
-for some processor types. If in doubt, boot with nmi_watchdog=1 and
-check the NMI count in /proc/interrupts; if the count is zero then
-reboot with nmi_watchdog=2 and check the NMI count. If it is still
-zero then log a problem, you probably have a processor that needs to be
-added to the nmi code.
-
-A 'lockup' is the following scenario: if any CPU in the system does not
-execute the period local timer interrupt for more than 5 seconds, then
-the NMI handler generates an oops and kills the process. This
-'controlled crash' (and the resulting kernel messages) can be used to
-debug the lockup. Thus whenever the lockup happens, wait 5 seconds and
-the oops will show up automatically. If the kernel produces no messages
-then the system has crashed so hard (eg. hardware-wise) that either it
-cannot even accept NMI interrupts, or the crash has made the kernel
-unable to print messages.
-
-Be aware that when using local APIC, the frequency of NMI interrupts
-it generates, depends on the system load. The local APIC NMI watchdog,
-lacking a better source, uses the "cycles unhalted" event. As you may
-guess it doesn't tick when the CPU is in the halted state (which happens
-when the system is idle), but if your system locks up on anything but the
-"hlt" processor instruction, the watchdog will trigger very soon as the
-"cycles unhalted" event will happen every clock tick. If it locks up on
-"hlt", then you are out of luck -- the event will not happen at all and the
-watchdog won't trigger. This is a shortcoming of the local APIC watchdog
--- unfortunately there is no "clock ticks" event that would work all the
-time. The I/O APIC watchdog is driven externally and has no such shortcoming.
-But its NMI frequency is much higher, resulting in a more significant hit
-to the overall system performance.
-
-On x86 nmi_watchdog is disabled by default so you have to enable it with
-a boot time parameter.
-
-It's possible to disable the NMI watchdog in run-time by writing "0" to
-/proc/sys/kernel/nmi_watchdog. Writing "1" to the same file will re-enable
-the NMI watchdog. Notice that you still need to use "nmi_watchdog=" parameter
-at boot time.
-
-NOTE: In kernels prior to 2.4.2-ac18 the NMI-oopser is enabled unconditionally
-on x86 SMP boxes.

You register this pinmux mapping to the pinmux subsystem by simply:
- ret = pinmux_register_mappings(pmx_mapping, ARRAY_SIZE(pmx_mapping));
+ ret = pinctrl_register_mappings(mapping, ARRAY_SIZE(mapping));
Since the above construct is pretty common there is a helper macro to make
it even more compact which assumes you want to use pinctrl-foo and position
0 for mapping, for example:
-static struct pinmux_map __initdata pmx_mapping[] = {
- PINMUX_MAP("I2CMAP", "pinctrl-foo", "i2c0", "foo-i2c.0"),
+static struct pinctrl_map __initdata mapping[] = {
+ PIN_MAP_MUX_GROUP("foo-i2c.o", PINCTRL_STATE_DEFAULT, "pinctrl-foo", NULL, "i2c0"),
+};
+
+The mapping table may also contain pin configuration entries. It's common for
+each pin/group to have a number of configuration entries that affect it, so
+the table entries for configuration reference an array of config parameters
+and values. An example using the convenience macros is shown below:
+
+static unsigned long i2c_grp_configs[] = {

+ FOO_PIN_PULLUP,

+

+
+ Firmware-Assisted Dump
+ ------------------------
+ July 2011
+
+The goal of firmware-assisted dump is to enable the dump of
+a crashed system, and to do so from a fully-reset system, and
+to minimize the total elapsed time until the system is back
+in production use.
+
+- Firmware assisted dump (fadump) infrastructure is intended to replace
+ the existing phyp assisted dump.
+- Fadump uses the same firmware interfaces and memory reservation model
+ as phyp assisted dump.
+- Unlike phyp dump, fadump exports the memory dump through /proc/vmcore
+ in the ELF format in the same way as kdump. This helps us reuse the
+ kdump infrastructure for dump capture and filtering.
+- Unlike phyp dump, userspace tool does not need to refer any sysfs
+ interface while reading /proc/vmcore.
+- Unlike phyp dump, fadump allows user to release all the memory reserved
+ for dump, with a single operation of echo 1 > /sys/kernel/fadump_release_mem.
+- Once enabled through kernel boot parameter, fadump can be
+ started/stopped through /sys/kernel/fadump_registered interface (see
+ sysfs files section below) and can be easily integrated with kdump
+ service start/stop init scripts.
+
+Comparing with kdump or other strategies, firmware-assisted
+dump offers several strong, practical advantages:
+
+-- Unlike kdump, the system has been reset, and loaded
+ with a fresh copy of the kernel. In particular,
+ PCI and I/O devices have been reinitialized and are
+ in a clean, consistent state.
+-- Once the dump is copied out, the memory that held the dump
+ is immediately available to the running kernel. And therefore,
+ unlike kdump, fadump doesn't need a 2nd reboot to get back
+ the system to the production configuration.
+
+The above can only be accomplished by coordination with,
+and assistance from the Power firmware. The procedure is
+as follows:
+
+-- The first kernel registers the sections of memory with the
+ Power firmware for dump preservation during OS initialization.
+ These registered sections of memory are reserved by the first
+ kernel during early boot.
+
+-- When a system crashes, the Power firmware will save
+ the low memory (boot memory of size larger of 5% of system RAM
+ or 256MB) of RAM to the previous registered region. It will
+ also save system registers, and hardware PTE's.
+
+ NOTE: The term 'boot memory' means size of the low memory chunk
+ that is required for a kernel to boot successfully when
+ booted with restricted memory. By default, the boot memory
+ size will be the larger of 5% of system RAM or 256MB.
+ Alternatively, user can also specify boot memory size
+ through boot parameter 'fadump_reserve_mem=' which will
+ override the default calculated size. Use this option
+ if default boot memory size is not sufficient for second
+ kernel to boot successfully.
+
+-- After the low memory (boot memory) area has been saved, the
+ firmware will reset PCI and other hardware state. It will
+ *not* clear the RAM. It will then launch the bootloader, as
+ normal.
+
+-- The freshly booted kernel will notice that there is a new
+ node (ibm,dump-kernel) in the device tree, indicating that
+ there is crash data available from a previous boot. During
+ the early boot OS will reserve rest of the memory above
+ boot memory size effectively booting with restricted memory
+ size. This will make sure that the second kernel will not
+ touch any of the dump memory area.
+
+-- User-space tools will read /proc/vmcore to obtain the contents
+ of memory, which holds the previous crashed kernel dump in ELF
+ format. The userspace tools may copy this info to disk, or
+ network, nas, san, iscsi, etc. as desired.
+
+-- Once the userspace tool is done saving dump, it will echo
+ '1' to /sys/kernel/fadump_release_mem to release the reserved
+ memory back to general use, except the memory required for
+ next firmware-assisted dump registration.
+
+ e.g.
+ # echo 1 > /sys/kernel/fadump_release_mem
+
+Please note that the firmware-assisted dump feature
+is only available on Power6 and above systems with recent
+firmware versions.
+
+Implementation details:
+----------------------
+
+During boot, a check is made to see if firmware supports
+this feature on that particular machine. If it does, then
+we check to see if an active dump is waiting for us. If yes
+then everything but boot memory size of RAM is reserved during
+early boot (See Fig. 2). This area is released once we finish
+collecting the dump from user land scripts (e.g. kdump scripts)
+that are run. If there is dump data, then the
+/sys/kernel/fadump_release_mem file is created, and the reserved
+memory is held.
+
+If there is no waiting dump data, then only the memory required
+to hold CPU state, HPTE region, boot memory dump and elfcore
+header, is reserved at the top of memory (see Fig. 1). This area
+is *not* released: this region will be kept permanently reserved,
+so that it can act as a receptacle for a copy of the boot memory
+content in addition to CPU state and HPTE region, in the case a
+crash does occur.

+ kernel to boot
+ Fig. 2
+
+Currently the dump will be copied from /proc/vmcore to a
+a new file upon user intervention. The dump data available through
+/proc/vmcore will be in ELF format. Hence the existing kdump
+infrastructure (kdump scripts) to save the dump works fine with
+minor modifications.
+
+The tools to examine the dump will be same as the ones
+used for kdump.
+
+How to enable firmware-assisted dump (fadump):
+-------------------------------------
+
+1. Set config option CONFIG_FA_DUMP=y and build kernel.
+2. Boot into linux kernel with 'fadump=on' kernel cmdline option.
+3. Optionally, user can also set 'fadump_reserve_mem=' kernel cmdline
+ to specify size of the memory to reserve for boot memory dump
+ preservation.
+
+NOTE: If firmware-assisted dump fails to reserve memory then it will
+ fallback to existing kdump mechanism if 'crashkernel=' option
+ is set at kernel cmdline.
+
+Sysfs/debugfs files:
+------------
+
+Firmware-assisted dump feature uses sysfs file system to hold
+the control files and debugfs file to display memory reserved region.
+
+Here is the list of files under kernel sysfs:
+
+ /sys/kernel/fadump_enabled
+
+ This is used to display the fadump status.
+ 0 = fadump is disabled
+ 1 = fadump is enabled
+
+ This interface can be used by kdump init scripts to identify if
+ fadump is enabled in the kernel and act accordingly.
+
+ /sys/kernel/fadump_registered
+
+ This is used to display the fadump registration status as well
+ as to control (start/stop) the fadump registration.
+ 0 = fadump is not registered.
+ 1 = fadump is registered and ready to handle system crash.
+
+ To register fadump echo 1 > /sys/kernel/fadump_registered and
+ echo 0 > /sys/kernel/fadump_registered for un-register and stop the
+ fadump. Once the fadump is un-registered, the system crash will not
+ be handled and vmcore will not be captured. This interface can be
+ easily integrated with kdump service start/stop.
+
+ /sys/kernel/fadump_release_mem
+
+ This file is available only when fadump is active during
+ second kernel. This is used to release the reserved memory
+ region that are held for saving crash dump. To release the
+ reserved memory echo 1 to it:
+
+ echo 1 > /sys/kernel/fadump_release_mem
+
+ After echo 1, the content of the /sys/kernel/debug/powerpc/fadump_region
+ file will change to reflect the new memory reservations.
+
+ The existing userspace tools (kdump infrastructure) can be easily
+ enhanced to use this interface to release the memory reserved for
+ dump and continue without 2nd reboot.
+
+Here is the list of files under powerpc debugfs:
+(Assuming debugfs is mounted on /sys/kernel/debug directory.)
+
+ /sys/kernel/debug/powerpc/fadump_region
+
+ This file shows the reserved memory regions if fadump is
+ enabled otherwise this file is empty. The output format
+ is:
+ <region>: [<start>-<end>] <reserved-size> bytes, Dumped: <dump-size>
+
+ e.g.
+ Contents when fadump is registered during first kernel
+
+ # cat /sys/kernel/debug/powerpc/fadump_region
+ CPU : [0x0000006ffb0000-0x0000006fff001f] 0x40020 bytes, Dumped: 0x0
+ HPTE: [0x0000006fff0020-0x0000006fff101f] 0x1000 bytes, Dumped: 0x0
+ DUMP: [0x0000006fff1020-0x0000007fff101f] 0x10000000 bytes, Dumped: 0x0
+
+ Contents when fadump is active during second kernel
+
+ # cat /sys/kernel/debug/powerpc/fadump_region
+ CPU : [0x0000006ffb0000-0x0000006fff001f] 0x40020 bytes, Dumped: 0x40020
+ HPTE: [0x0000006fff0020-0x0000006fff101f] 0x1000 bytes, Dumped: 0x1000
+ DUMP: [0x0000006fff1020-0x0000007fff101f] 0x10000000 bytes, Dumped: 0x10000000
+ : [0x00000010000000-0x0000006ffaffff] 0x5ffb0000 bytes, Dumped: 0x5ffb0000
+
+NOTE: Please refer to Documentation/filesystems/debugfs.txt on
+ how to mount the debugfs filesystem.
+
+
+TODO:
+-----
+ o Need to come up with the better approach to find out more
+ accurate boot memory size that is required for a kernel to
+ boot successfully when booted with restricted memory.
+ o The fadump implementation introduces a fadump crash info structure
+ in the scratch area before the ELF core header. The idea of introducing
+ this structure is to pass some important crash info data to the second
+ kernel which will help second kernel to populate ELF core header with
+ correct data before it gets exported through /proc/vmcore. The current
+ design implementation does not address a possibility of introducing
+ additional fields (in future) to this structure without affecting
+ compatibility. Need to come up with the better approach to address this.
+ The possible approaches are:
+ 1. Introduce version field for version tracking, bump up the version
+ whenever a new field is added to the structure in future. The version
+ field can be used to find out what fields are valid for the current
+ version of the structure.
+ 2. Reserve the area of predefined size (say PAGE_SIZE) for this
+ structure and have unused area as reserved (initialized to zero)
+ for future field additions.
+ The advantage of approach 1 over 2 is we don't need to reserve extra space.

- Hypervisor-Assisted Dump
- ------------------------
- November 2007

-The goal of hypervisor-assisted dump is to enable the dump of

--- As the dump is performed, the dumped memory becomes
- immediately available to the system for normal use.
--- After the dump is completed, no further reboots are
- required; the system will be fully usable, and running
- in its normal, production mode on its normal kernel.
-
-The above can only be accomplished by coordination with,
-and assistance from the hypervisor. The procedure is
-as follows:
-
--- When a system crashes, the hypervisor will save
- the low 256MB of RAM to a previously registered
- save region. It will also save system state, system
- registers, and hardware PTE's.
-
--- After the low 256MB area has been saved, the
- hypervisor will reset PCI and other hardware state.
- It will *not* clear RAM. It will then launch the
- bootloader, as normal.
-
--- The freshly booted kernel will notice that there
- is a new node (ibm,dump-kernel) in the device tree,
- indicating that there is crash data available from
- a previous boot. It will boot into only 256MB of RAM,
- reserving the rest of system memory.
-
--- Userspace tools will parse /sys/kernel/release_region
- and read /proc/vmcore to obtain the contents of memory,
- which holds the previous crashed kernel. The userspace
- tools may copy this info to disk, or network, nas, san,
- iscsi, etc. as desired.
-
- For Example: the values in /sys/kernel/release-region
- would look something like this (address-range pairs).
- CPU:0x177fee000-0x10000: HPTE:0x177ffe020-0x1000: /
- DUMP:0x177fff020-0x10000000, 0x10000000-0x16F1D370A
-
--- As the userspace tools complete saving a portion of
- dump, they echo an offset and size to
- /sys/kernel/release_region to release the reserved
- memory back to general use.
-
- An example of this is:
- "echo 0x40000000 0x10000000 > /sys/kernel/release_region"
- which will release 256MB at the 1GB boundary.
-
-Please note that the hypervisor-assisted dump feature
-is only available on Power6-based systems with recent
-firmware versions.
-
-Implementation details:
-----------------------
-
-During boot, a check is made to see if firmware supports

-
-If there is no waiting dump data, then only the highest
-256MB of the ram is reserved as a scratch area. This area
-is *not* released: this region will be kept permanently
-reserved, so that it can act as a receptacle for a copy
-of the low 256MB in the case a crash does occur. See,
-however, "open issues" below, as to whether
-such a reserved region is really needed.
-
-Currently the dump will be copied from /proc/vmcore to a

-in /sys/kernel/release_region.
-
-The tools to examine the dump will be same as the ones
-used for kdump.
-
-General notes:
---------------
-Security: please note that there are potential security issues
-with any sort of dump mechanism. In particular, plaintext
-(unencrypted) data, and possibly passwords, may be present in
-the dump data. Userspace tools must take adequate precautions to
-preserve security.
-
-Open issues/ToDo:
-------------
- o The various code paths that tell the hypervisor that a crash
- occurred, vs. it simply being a normal reboot, should be
- reviewed, and possibly clarified/fixed.
-
- o Instead of using /sys/kernel, should there be a /sys/dump
- instead? There is a dump_subsys being created by the s390 code,
- perhaps the pseries code should use a similar layout as well.
-
- o Is reserving a 256MB region really required? The goal of
- reserving a 256MB scratch area is to make sure that no
- important crash data is clobbered when the hypervisor
- save low mem to the scratch area. But, if one could assure
- that nothing important is located in some 256MB area, then
- it would not need to be reserved. Something that can be
- improved in subsequent versions.
-
- o Still working the kdump team to integrate this with kdump,
- some work remains but this would not affect the current
- patches.
-
- o Still need to write a shell script, to copy the dump away.
- Currently I am parsing it manually.

+Remote Processor Framework
+
+1. Introduction
+
+Modern SoCs typically have heterogeneous remote processor devices in asymmetric
+multiprocessing (AMP) configurations, which may be running different instances
+of operating system, whether it's Linux or any other flavor of real-time OS.
+
+OMAP4, for example, has dual Cortex-A9, dual Cortex-M3 and a C64x+ DSP.
+In a typical configuration, the dual cortex-A9 is running Linux in a SMP
+configuration, and each of the other three cores (two M3 cores and a DSP)
+is running its own instance of RTOS in an AMP configuration.
+
+The remoteproc framework allows different platforms/architectures to
+control (power on, load firmware, power off) those remote processors while
+abstracting the hardware differences, so the entire driver doesn't need to be
+duplicated. In addition, this framework also adds rpmsg virtio devices
+for remote processors that supports this kind of communication. This way,
+platform-specific remoteproc drivers only need to provide a few low-level
+handlers, and then all rpmsg drivers will then just work
+(for more information about the virtio-based rpmsg bus and its drivers,
+please read Documentation/rpmsg.txt).
+Registration of other types of virtio devices is now also possible. Firmwares
+just need to publish what kind of virtio devices do they support, and then
+remoteproc will add those devices. This makes it possible to reuse the
+existing virtio drivers with remote processor backends at a minimal development
+cost.
+
+2. User API
+
+ int rproc_boot(struct rproc *rproc)
+ - Boot a remote processor (i.e. load its firmware, power it on, ...).
+ If the remote processor is already powered on, this function immediately
+ returns (successfully).
+ Returns 0 on success, and an appropriate error value otherwise.
+ Note: to use this function you should already have a valid rproc
+ handle. There are several ways to achieve that cleanly (devres, pdata,
+ the way remoteproc_rpmsg.c does this, or, if this becomes prevalent, we
+ might also consider using dev_archdata for this). See also
+ rproc_get_by_name() below.
+
+ void rproc_shutdown(struct rproc *rproc)
+ - Power off a remote processor (previously booted with rproc_boot()).
+ In case @rproc is still being used by an additional user(s), then
+ this function will just decrement the power refcount and exit,
+ without really powering off the device.
+ Every call to rproc_boot() must (eventually) be accompanied by a call
+ to rproc_shutdown(). Calling rproc_shutdown() redundantly is a bug.
+ Notes:
+ - we're not decrementing the rproc's refcount, only the power refcount.
+ which means that the @rproc handle stays valid even after
+ rproc_shutdown() returns, and users can still use it with a subsequent
+ rproc_boot(), if needed.
+ - don't call rproc_shutdown() to unroll rproc_get_by_name(), exactly
+ because rproc_shutdown() _does not_ decrement the refcount of @rproc.
+ To decrement the refcount of @rproc, use rproc_put() (but _only_ if
+ you acquired @rproc using rproc_get_by_name()).
+
+ struct rproc *rproc_get_by_name(const char *name)
+ - Find an rproc handle using the remote processor's name, and then
+ boot it. If it's already powered on, then just immediately return
+ (successfully). Returns the rproc handle on success, and NULL on failure.
+ This function increments the remote processor's refcount, so always
+ use rproc_put() to decrement it back once rproc isn't needed anymore.
+ Note: currently rproc_get_by_name() and rproc_put() are not used anymore
+ by the rpmsg bus and its drivers. We need to scrutinize the use cases
+ that still need them, and see if we can migrate them to use the non
+ name-based boot/shutdown interface.
+
+ void rproc_put(struct rproc *rproc)
+ - Decrement @rproc's power refcount and shut it down if it reaches zero
+ (essentially by just calling rproc_shutdown), and then decrement @rproc's
+ validity refcount too.
+ After this function returns, @rproc may _not_ be used anymore, and its
+ handle should be considered invalid.
+ This function should be called _iff_ the @rproc handle was grabbed by
+ calling rproc_get_by_name().
+
+3. Typical usage
+
+#include <linux/remoteproc.h>
+
+/* in case we were given a valid 'rproc' handle */
+int dummy_rproc_example(struct rproc *my_rproc)
+{
+ int ret;
+
+ /* let's power on and boot our remote processor */
+ ret = rproc_boot(my_rproc);
+ if (ret) {
+ /*
+ * something went wrong. handle it and leave.
+ */
+ }
+
+ /*
+ * our remote processor is now powered on... give it some work
+ */
+
+ /* let's shut it down now */
+ rproc_shutdown(my_rproc);
+}
+
+4. API for implementors
+
+ struct rproc *rproc_alloc(struct device *dev, const char *name,
+ const struct rproc_ops *ops,
+ const char *firmware, int len)
+ - Allocate a new remote processor handle, but don't register
+ it yet. Required parameters are the underlying device, the
+ name of this remote processor, platform-specific ops handlers,
+ the name of the firmware to boot this rproc with, and the
+ length of private data needed by the allocating rproc driver (in bytes).
+
+ This function should be used by rproc implementations during
+ initialization of the remote processor.
+ After creating an rproc handle using this function, and when ready,
+ implementations should then call rproc_register() to complete
+ the registration of the remote processor.
+ On success, the new rproc is returned, and on failure, NULL.
+
+ Note: _never_ directly deallocate @rproc, even if it was not registered
+ yet. Instead, if you just need to unroll rproc_alloc(), use rproc_free().
+
+ void rproc_free(struct rproc *rproc)
+ - Free an rproc handle that was allocated by rproc_alloc.
+ This function should _only_ be used if @rproc was only allocated,
+ but not registered yet.
+ If @rproc was already successfully registered (by calling
+ rproc_register()), then use rproc_unregister() instead.
+
+ int rproc_register(struct rproc *rproc)
+ - Register @rproc with the remoteproc framework, after it has been
+ allocated with rproc_alloc().
+ This is called by the platform-specific rproc implementation, whenever
+ a new remote processor device is probed.
+ Returns 0 on success and an appropriate error code otherwise.
+ Note: this function initiates an asynchronous firmware loading
+ context, which will look for virtio devices supported by the rproc's
+ firmware.
+ If found, those virtio devices will be created and added, so as a result
+ of registering this remote processor, additional virtio drivers might get
+ probed.
+
+ int rproc_unregister(struct rproc *rproc)
+ - Unregister a remote processor, and decrement its refcount.
+ If its refcount drops to zero, then @rproc will be freed. If not,
+ it will be freed later once the last reference is dropped.
+
+ This function should be called when the platform specific rproc
+ implementation decides to remove the rproc device. it should
+ _only_ be called if a previous invocation of rproc_register()
+ has completed successfully.
+
+ After rproc_unregister() returns, @rproc is _not_ valid anymore and
+ it shouldn't be used. More specifically, don't call rproc_free()
+ or try to directly free @rproc after rproc_unregister() returns;
+ none of these are needed, and calling them is a bug.
+
+ Returns 0 on success and -EINVAL if @rproc isn't valid.
+
+5. Implementation callbacks
+
+These callbacks should be provided by platform-specific remoteproc
+drivers:
+
+/**
+ * struct rproc_ops - platform-specific device handlers
+ * @start: power on the device and boot it
+ * @stop: power off the device
+ * @kick: kick a virtqueue (virtqueue id given as a parameter)
+ */
+struct rproc_ops {
+ int (*start)(struct rproc *rproc);
+ int (*stop)(struct rproc *rproc);
+ void (*kick)(struct rproc *rproc, int vqid);
+};
+
+Every remoteproc implementation should at least provide the ->start and ->stop
+handlers. If rpmsg/virtio functionality is also desired, then the ->kick handler
+should be provided as well.
+
+The ->start() handler takes an rproc handle and should then power on the
+device and boot it (use rproc->priv to access platform-specific private data).
+The boot address, in case needed, can be found in rproc->bootaddr (remoteproc
+core puts there the ELF entry point).
+On success, 0 should be returned, and on failure, an appropriate error code.
+
+The ->stop() handler takes an rproc handle and powers the device down.
+On success, 0 is returned, and on failure, an appropriate error code.
+
+The ->kick() handler takes an rproc handle, and an index of a virtqueue
+where new message was placed in. Implementations should interrupt the remote
+processor and let it know it has pending messages. Notifying remote processors
+the exact virtqueue index to look in is optional: it is easy (and not
+too expensive) to go through the existing virtqueues and look for new buffers
+in the used rings.
+
+6. Binary Firmware Structure
+
+At this point remoteproc only supports ELF32 firmware binaries. However,
+it is quite expected that other platforms/devices which we'd want to
+support with this framework will be based on different binary formats.
+
+When those use cases show up, we will have to decouple the binary format
+from the framework core, so we can support several binary formats without
+duplicating common code.
+
+When the firmware is parsed, its various segments are loaded to memory
+according to the specified device address (might be a physical address
+if the remote processor is accessing memory directly).
+
+In addition to the standard ELF segments, most remote processors would
+also include a special section which we call "the resource table".
+
+The resource table contains system resources that the remote processor
+requires before it should be powered on, such as allocation of physically
+contiguous memory, or iommu mapping of certain on-chip peripherals.
+Remotecore will only power up the device after all the resource table's
+requirement are met.
+
+In addition to system resources, the resource table may also contain
+resource entries that publish the existence of supported features
+or configurations by the remote processor, such as trace buffers and
+supported virtio devices (and their configurations).
+
+The resource table begins with this header:
+
+/**
+ * struct resource_table - firmware resource table header
+ * @ver: version number
+ * @num: number of resource entries
+ * @reserved: reserved (must be zero)
+ * @offset: array of offsets pointing at the various resource entries
+ *
+ * The header of the resource table, as expressed by this structure,
+ * contains a version number (should we need to change this format in the
+ * future), the number of available resource entries, and their offsets
+ * in the table.
+ */
+struct resource_table {
+ u32 ver;
+ u32 num;
+ u32 reserved[2];
+ u32 offset[0];
+} __packed;
+
+Immediately following this header are the resource entries themselves,
+each of which begins with the following resource entry header:
+
+/**
+ * struct fw_rsc_hdr - firmware resource entry header
+ * @type: resource type
+ * @data: resource data
+ *
+ * Every resource entry begins with a 'struct fw_rsc_hdr' header providing
+ * its @type. The content of the entry itself will immediately follow
+ * this header, and it should be parsed according to the resource type.
+ */
+struct fw_rsc_hdr {
+ u32 type;
+ u8 data[0];
+} __packed;
+
+Some resources entries are mere announcements, where the host is informed
+of specific remoteproc configuration. Other entries require the host to
+do something (e.g. allocate a system resource). Sometimes a negotiation
+is expected, where the firmware requests a resource, and once allocated,
+the host should provide back its details (e.g. address of an allocated
+memory region).
+
+Here are the various resource types that are currently supported:
+
+/**
+ * enum fw_resource_type - types of resource entries
+ *
+ * @RSC_CARVEOUT: request for allocation of a physically contiguous
+ * memory region.
+ * @RSC_DEVMEM: request to iommu_map a memory-based peripheral.
+ * @RSC_TRACE: announces the availability of a trace buffer into which
+ * the remote processor will be writing logs.
+ * @RSC_VDEV: declare support for a virtio device, and serve as its
+ * virtio header.
+ * @RSC_LAST: just keep this one at the end
+ *
+ * Please note that these values are used as indices to the rproc_handle_rsc
+ * lookup table, so please keep them sane. Moreover, @RSC_LAST is used to
+ * check the validity of an index before the lookup table is accessed, so
+ * please update it as needed.
+ */
+enum fw_resource_type {
+ RSC_CARVEOUT = 0,
+ RSC_DEVMEM = 1,
+ RSC_TRACE = 2,
+ RSC_VDEV = 3,
+ RSC_LAST = 4,
+};
+
+For more details regarding a specific resource type, please see its
+dedicated structure in include/linux/remoteproc.h.
+
+We also expect that platform-specific resource entries will show up
+at some point. When that happens, we could easily add a new RSC_PLATFORM
+type, and hand those resources to the platform-specific rproc driver to handle.
+
+7. Virtio and remoteproc
+
+The firmware should provide remoteproc information about virtio devices
+that it supports, and their configurations: a RSC_VDEV resource entry
+should specify the virtio device id (as in virtio_ids.h), virtio features,
+virtio config space, vrings information, etc.
+
+When a new remote processor is registered, the remoteproc framework
+will look for its resource table and will register the virtio devices
+it supports. A firmware may support any number of virtio devices, and
+of any type (a single remote processor can also easily support several
+rpmsg virtio devices this way, if desired).
+
+Of course, RSC_VDEV resource entries are only good enough for static
+allocation of virtio devices. Dynamic allocations will also be made possible
+using the rpmsg bus (similar to how we already do dynamic allocations of
+rpmsg channels; read more about it in rpmsg.txt).

+Remote Processor Messaging (rpmsg) Framework
+
+Note: this document describes the rpmsg bus and how to write rpmsg drivers.
+To learn how to add rpmsg support for new platforms, check out remoteproc.txt
+(also a resident of Documentation/).
+
+1. Introduction
+
+Modern SoCs typically employ heterogeneous remote processor devices in
+asymmetric multiprocessing (AMP) configurations, which may be running
+different instances of operating system, whether it's Linux or any other
+flavor of real-time OS.
+
+OMAP4, for example, has dual Cortex-A9, dual Cortex-M3 and a C64x+ DSP.
+Typically, the dual cortex-A9 is running Linux in a SMP configuration,
+and each of the other three cores (two M3 cores and a DSP) is running
+its own instance of RTOS in an AMP configuration.
+
+Typically AMP remote processors employ dedicated DSP codecs and multimedia
+hardware accelerators, and therefore are often used to offload CPU-intensive
+multimedia tasks from the main application processor.
+
+These remote processors could also be used to control latency-sensitive
+sensors, drive random hardware blocks, or just perform background tasks
+while the main CPU is idling.
+
+Users of those remote processors can either be userland apps (e.g. multimedia
+frameworks talking with remote OMX components) or kernel drivers (controlling
+hardware accessible only by the remote processor, reserving kernel-controlled
+resources on behalf of the remote processor, etc..).
+
+Rpmsg is a virtio-based messaging bus that allows kernel drivers to communicate
+with remote processors available on the system. In turn, drivers could then
+expose appropriate user space interfaces, if needed.
+
+When writing a driver that exposes rpmsg communication to userland, please
+keep in mind that remote processors might have direct access to the
+system's physical memory and other sensitive hardware resources (e.g. on
+OMAP4, remote cores and hardware accelerators may have direct access to the
+physical memory, gpio banks, dma controllers, i2c bus, gptimers, mailbox
+devices, hwspinlocks, etc..). Moreover, those remote processors might be
+running RTOS where every task can access the entire memory/devices exposed
+to the processor. To minimize the risks of rogue (or buggy) userland code
+exploiting remote bugs, and by that taking over the system, it is often
+desired to limit userland to specific rpmsg channels (see definition below)
+it can send messages on, and if possible, minimize how much control
+it has over the content of the messages.
+
+Every rpmsg device is a communication channel with a remote processor (thus
+rpmsg devices are called channels). Channels are identified by a textual name
+and have a local ("source") rpmsg address, and remote ("destination") rpmsg
+address.
+
+When a driver starts listening on a channel, its rx callback is bound with
+a unique rpmsg local address (a 32-bit integer). This way when inbound messages
+arrive, the rpmsg core dispatches them to the appropriate driver according
+to their destination address (this is done by invoking the driver's rx handler
+with the payload of the inbound message).
+
+
+2. User API
+
+ int rpmsg_send(struct rpmsg_channel *rpdev, void *data, int len);
+ - sends a message across to the remote processor on a given channel.
+ The caller should specify the channel, the data it wants to send,
+ and its length (in bytes). The message will be sent on the specified
+ channel, i.e. its source and destination address fields will be
+ set to the channel's src and dst addresses.
+
+ In case there are no TX buffers available, the function will block until
+ one becomes available (i.e. until the remote processor consumes
+ a tx buffer and puts it back on virtio's used descriptor ring),
+ or a timeout of 15 seconds elapses. When the latter happens,
+ -ERESTARTSYS is returned.
+ The function can only be called from a process context (for now).
+ Returns 0 on success and an appropriate error value on failure.
+
+ int rpmsg_sendto(struct rpmsg_channel *rpdev, void *data, int len, u32 dst);
+ - sends a message across to the remote processor on a given channel,
+ to a destination address provided by the caller.
+ The caller should specify the channel, the data it wants to send,
+ its length (in bytes), and an explicit destination address.
+ The message will then be sent to the remote processor to which the
+ channel belongs, using the channel's src address, and the user-provided
+ dst address (thus the channel's dst address will be ignored).
+
+ In case there are no TX buffers available, the function will block until
+ one becomes available (i.e. until the remote processor consumes
+ a tx buffer and puts it back on virtio's used descriptor ring),
+ or a timeout of 15 seconds elapses. When the latter happens,
+ -ERESTARTSYS is returned.
+ The function can only be called from a process context (for now).
+ Returns 0 on success and an appropriate error value on failure.
+
+ int rpmsg_send_offchannel(struct rpmsg_channel *rpdev, u32 src, u32 dst,
+ void *data, int len);
+ - sends a message across to the remote processor, using the src and dst
+ addresses provided by the user.
+ The caller should specify the channel, the data it wants to send,
+ its length (in bytes), and explicit source and destination addresses.
+ The message will then be sent to the remote processor to which the
+ channel belongs, but the channel's src and dst addresses will be
+ ignored (and the user-provided addresses will be used instead).
+
+ In case there are no TX buffers available, the function will block until
+ one becomes available (i.e. until the remote processor consumes
+ a tx buffer and puts it back on virtio's used descriptor ring),
+ or a timeout of 15 seconds elapses. When the latter happens,
+ -ERESTARTSYS is returned.
+ The function can only be called from a process context (for now).
+ Returns 0 on success and an appropriate error value on failure.
+
+ int rpmsg_trysend(struct rpmsg_channel *rpdev, void *data, int len);
+ - sends a message across to the remote processor on a given channel.
+ The caller should specify the channel, the data it wants to send,
+ and its length (in bytes). The message will be sent on the specified
+ channel, i.e. its source and destination address fields will be
+ set to the channel's src and dst addresses.
+
+ In case there are no TX buffers available, the function will immediately
+ return -ENOMEM without waiting until one becomes available.
+ The function can only be called from a process context (for now).
+ Returns 0 on success and an appropriate error value on failure.
+
+ int rpmsg_trysendto(struct rpmsg_channel *rpdev, void *data, int len, u32 dst)
+ - sends a message across to the remote processor on a given channel,
+ to a destination address provided by the user.
+ The user should specify the channel, the data it wants to send,
+ its length (in bytes), and an explicit destination address.
+ The message will then be sent to the remote processor to which the
+ channel belongs, using the channel's src address, and the user-provided
+ dst address (thus the channel's dst address will be ignored).
+
+ In case there are no TX buffers available, the function will immediately
+ return -ENOMEM without waiting until one becomes available.
+ The function can only be called from a process context (for now).
+ Returns 0 on success and an appropriate error value on failure.
+
+ int rpmsg_trysend_offchannel(struct rpmsg_channel *rpdev, u32 src, u32 dst,
+ void *data, int len);
+ - sends a message across to the remote processor, using source and
+ destination addresses provided by the user.
+ The user should specify the channel, the data it wants to send,
+ its length (in bytes), and explicit source and destination addresses.
+ The message will then be sent to the remote processor to which the
+ channel belongs, but the channel's src and dst addresses will be
+ ignored (and the user-provided addresses will be used instead).
+
+ In case there are no TX buffers available, the function will immediately
+ return -ENOMEM without waiting until one becomes available.
+ The function can only be called from a process context (for now).
+ Returns 0 on success and an appropriate error value on failure.
+
+ struct rpmsg_endpoint *rpmsg_create_ept(struct rpmsg_channel *rpdev,
+ void (*cb)(struct rpmsg_channel *, void *, int, void *, u32),
+ void *priv, u32 addr);
+ - every rpmsg address in the system is bound to an rx callback (so when
+ inbound messages arrive, they are dispatched by the rpmsg bus using the
+ appropriate callback handler) by means of an rpmsg_endpoint struct.
+
+ This function allows drivers to create such an endpoint, and by that,
+ bind a callback, and possibly some private data too, to an rpmsg address
+ (either one that is known in advance, or one that will be dynamically
+ assigned for them).
+
+ Simple rpmsg drivers need not call rpmsg_create_ept, because an endpoint
+ is already created for them when they are probed by the rpmsg bus
+ (using the rx callback they provide when they registered to the rpmsg bus).
+
+ So things should just work for simple drivers: they already have an
+ endpoint, their rx callback is bound to their rpmsg address, and when
+ relevant inbound messages arrive (i.e. messages which their dst address
+ equals to the src address of their rpmsg channel), the driver's handler
+ is invoked to process it.
+
+ That said, more complicated drivers might do need to allocate
+ additional rpmsg addresses, and bind them to different rx callbacks.
+ To accomplish that, those drivers need to call this function.
+ Drivers should provide their channel (so the new endpoint would bind
+ to the same remote processor their channel belongs to), an rx callback
+ function, an optional private data (which is provided back when the
+ rx callback is invoked), and an address they want to bind with the
+ callback. If addr is RPMSG_ADDR_ANY, then rpmsg_create_ept will
+ dynamically assign them an available rpmsg address (drivers should have
+ a very good reason why not to always use RPMSG_ADDR_ANY here).
+
+ Returns a pointer to the endpoint on success, or NULL on error.
+
+ void rpmsg_destroy_ept(struct rpmsg_endpoint *ept);
+ - destroys an existing rpmsg endpoint. user should provide a pointer
+ to an rpmsg endpoint that was previously created with rpmsg_create_ept().
+
+ int register_rpmsg_driver(struct rpmsg_driver *rpdrv);
+ - registers an rpmsg driver with the rpmsg bus. user should provide
+ a pointer to an rpmsg_driver struct, which contains the driver's
+ ->probe() and ->remove() functions, an rx callback, and an id_table
+ specifying the names of the channels this driver is interested to
+ be probed with.
+
+ void unregister_rpmsg_driver(struct rpmsg_driver *rpdrv);
+ - unregisters an rpmsg driver from the rpmsg bus. user should provide
+ a pointer to a previously-registered rpmsg_driver struct.
+ Returns 0 on success, and an appropriate error value on failure.
+
+
+3. Typical usage
+
+The following is a simple rpmsg driver, that sends an "hello!" message
+on probe(), and whenever it receives an incoming message, it dumps its
+content to the console.
+
+#include <linux/kernel.h>
+#include <linux/module.h>
+#include <linux/rpmsg.h>
+
+static void rpmsg_sample_cb(struct rpmsg_channel *rpdev, void *data, int len,
+ void *priv, u32 src)
+{
+ print_hex_dump(KERN_INFO, "incoming message:", DUMP_PREFIX_NONE,
+ 16, 1, data, len, true);
+}
+
+static int rpmsg_sample_probe(struct rpmsg_channel *rpdev)
+{
+ int err;
+
+ dev_info(&rpdev->dev, "chnl: 0x%x -> 0x%x\n", rpdev->src, rpdev->dst);
+
+ /* send a message on our channel */
+ err = rpmsg_send(rpdev, "hello!", 6);
+ if (err) {
+ pr_err("rpmsg_send failed: %d\n", err);
+ return err;
+ }
+
+ return 0;
+}
+
+static void __devexit rpmsg_sample_remove(struct rpmsg_channel *rpdev)
+{
+ dev_info(&rpdev->dev, "rpmsg sample client driver is removed\n");
+}
+
+static struct rpmsg_device_id rpmsg_driver_sample_id_table[] = {
+ { .name = "rpmsg-client-sample" },
+ { },
+};
+MODULE_DEVICE_TABLE(rpmsg, rpmsg_driver_sample_id_table);
+
+static struct rpmsg_driver rpmsg_sample_client = {
+ .drv.name = KBUILD_MODNAME,
+ .drv.owner = THIS_MODULE,
+ .id_table = rpmsg_driver_sample_id_table,
+ .probe = rpmsg_sample_probe,
+ .callback = rpmsg_sample_cb,
+ .remove = __devexit_p(rpmsg_sample_remove),
+};
+
+static int __init init(void)
+{
+ return register_rpmsg_driver(&rpmsg_sample_client);
+}
+module_init(init);
+
+static void __exit fini(void)
+{
+ unregister_rpmsg_driver(&rpmsg_sample_client);
+}
+module_exit(fini);
+
+Note: a similar sample which can be built and loaded can be found
+in samples/rpmsg/.
+
+4. Allocations of rpmsg channels:
+
+At this point we only support dynamic allocations of rpmsg channels.
+
+This is possible only with remote processors that have the VIRTIO_RPMSG_F_NS
+virtio device feature set. This feature bit means that the remote
+processor supports dynamic name service announcement messages.
+
+When this feature is enabled, creation of rpmsg devices (i.e. channels)
+is completely dynamic: the remote processor announces the existence of a
+remote rpmsg service by sending a name service message (which contains
+the name and rpmsg addr of the remote service, see struct rpmsg_ns_msg).
+
+This message is then handled by the rpmsg bus, which in turn dynamically
+creates and registers an rpmsg channel (which represents the remote service).
+If/when a relevant rpmsg driver is registered, it will be immediately probed
+by the bus, and can then start sending messages to the remote service.
+
+The plan is also to add static creation of rpmsg channels via the virtio
+config space, but it's not implemented yet.

+- ptrace_scope
+
+==============================================================
+
+ptrace_scope:
+
+As Linux grows in popularity, it will become a larger target for
+malware. One particularly troubling weakness of the Linux process
+interfaces is that a single user is able to examine the memory and
+running state of any of their processes. For example, if one application
+(e.g. Pidgin) was compromised, it would be possible for an attacker to
+attach to other running processes (e.g. Firefox, SSH sessions, GPG agent,
+etc) to extract additional credentials and continue to expand the scope
+of their attack without resorting to user-assisted phishing.
+
+This is not a theoretical problem. SSH session hijacking
+(http://www.storm.net.nz/projects/7) and arbitrary code injection
+(http://c-skills.blogspot.com/2007/05/injectso.html) attacks already
+exist and remain possible if ptrace is allowed to operate as before.
+Since ptrace is not commonly used by non-developers and non-admins, system
+builders should be allowed the option to disable this debugging system.
+
+For a solution, some applications use prctl(PR_SET_DUMPABLE, ...) to
+specifically disallow such ptrace attachment (e.g. ssh-agent), but many
+do not. A more general solution is to only allow ptrace directly from a
+parent to a child process (i.e. direct "gdb EXE" and "strace EXE" still
+work), or with CAP_SYS_PTRACE (i.e. "gdb --pid=PID", and "strace -p PID"
+still work as root).
+
+For software that has defined application-specific relationships
+between a debugging process and its inferior (crash handlers, etc),
+prctl(PR_SET_PTRACER, pid, ...) can be used. An inferior can declare which
+other process (and its descendents) are allowed to call PTRACE_ATTACH
+against it. Only one such declared debugging process can exists for
+each inferior at a time. For example, this is used by KDE, Chromium, and
+Firefox's crash handlers, and by Wine for allowing only Wine processes
+to ptrace each other. If a process wishes to entirely disable these ptrace
+restrictions, it can call prctl(PR_SET_PTRACER, PR_SET_PTRACER_ANY, ...)
+so that any otherwise allowed process (even those in external pid namespaces)
+may attach.
+
+The sysctl settings are:
+
+0 - classic ptrace permissions: a process can PTRACE_ATTACH to any other
+ process running under the same uid, as long as it is dumpable (i.e.
+ did not transition uids, start privileged, or have called
+ prctl(PR_SET_DUMPABLE...) already).
+
+1 - restricted ptrace: a process must have a predefined relationship
+ with the inferior it wants to call PTRACE_ATTACH on. By default,
+ this relationship is that of only its descendants when the above
+ classic criteria is also met. To change the relationship, an
+ inferior can call prctl(PR_SET_PTRACER, debugger, ...) to declare
+ an allowed debugger PID to call PTRACE_ATTACH on the inferior.
+
+The original children-only logic was based on the restrictions in grsecurity.

+ Static Keys
+ -----------
+
+By: Jason Baron <jbaron@redhat.com>
+
+0) Abstract
+
+Static keys allows the inclusion of seldom used features in
+performance-sensitive fast-path kernel code, via a GCC feature and a code
+patching technique. A quick example:
+
+ struct static_key key = STATIC_KEY_INIT_FALSE;
+
+ ...
+
+ if (static_key_false(&key))
+ do unlikely code
+ else
+ do likely code
+
+ ...
+ static_key_slow_inc();
+ ...
+ static_key_slow_inc();
+ ...
+
+The static_key_false() branch will be generated into the code with as little
+impact to the likely code path as possible.
+
+
+1) Motivation
+
+
+Currently, tracepoints are implemented using a conditional branch. The
+conditional check requires checking a global variable for each tracepoint.
+Although the overhead of this check is small, it increases when the memory
+cache comes under pressure (memory cache lines for these global variables may
+be shared with other memory accesses). As we increase the number of tracepoints
+in the kernel this overhead may become more of an issue. In addition,
+tracepoints are often dormant (disabled) and provide no direct kernel
+functionality. Thus, it is highly desirable to reduce their impact as much as
+possible. Although tracepoints are the original motivation for this work, other
+kernel code paths should be able to make use of the static keys facility.
+
+
+2) Solution
+
+
+gcc (v4.5) adds a new 'asm goto' statement that allows branching to a label:
+
+http://gcc.gnu.org/ml/gcc-patches/2009-07/msg01556.html
+
+Using the 'asm goto', we can create branches that are either taken or not taken
+by default, without the need to check memory. Then, at run-time, we can patch
+the branch site to change the branch direction.
+
+For example, if we have a simple branch that is disabled by default:
+
+ if (static_key_false(&key))
+ printk("I am the true branch\n");
+
+Thus, by default the 'printk' will not be emitted. And the code generated will
+consist of a single atomic 'no-op' instruction (5 bytes on x86), in the
+straight-line code path. When the branch is 'flipped', we will patch the
+'no-op' in the straight-line codepath with a 'jump' instruction to the
+out-of-line true branch. Thus, changing branch direction is expensive but
+branch selection is basically 'free'. That is the basic tradeoff of this
+optimization.
+
+This lowlevel patching mechanism is called 'jump label patching', and it gives
+the basis for the static keys facility.
+
+3) Static key label API, usage and examples:
+
+
+In order to make use of this optimization you must first define a key:
+
+ struct static_key key;
+
+Which is initialized as:
+
+ struct static_key key = STATIC_KEY_INIT_TRUE;
+
+or:
+
+ struct static_key key = STATIC_KEY_INIT_FALSE;
+
+If the key is not initialized, it is default false. The 'struct static_key',
+must be a 'global'. That is, it can't be allocated on the stack or dynamically
+allocated at run-time.
+
+The key is then used in code as:
+
+ if (static_key_false(&key))
+ do unlikely code
+ else
+ do likely code
+
+Or:
+
+ if (static_key_true(&key))
+ do likely code
+ else
+ do unlikely code
+
+A key that is initialized via 'STATIC_KEY_INIT_FALSE', must be used in a
+'static_key_false()' construct. Likewise, a key initialized via
+'STATIC_KEY_INIT_TRUE' must be used in a 'static_key_true()' construct. A
+single key can be used in many branches, but all the branches must match the
+way that the key has been initialized.
+
+The branch(es) can then be switched via:
+
+ static_key_slow_inc(&key);
+ ...
+ static_key_slow_dec(&key);
+
+Thus, 'static_key_slow_inc()' means 'make the branch true', and
+'static_key_slow_dec()' means 'make the the branch false' with appropriate
+reference counting. For example, if the key is initialized true, a
+static_key_slow_dec(), will switch the branch to false. And a subsequent
+static_key_slow_inc(), will change the branch back to true. Likewise, if the
+key is initialized false, a 'static_key_slow_inc()', will change the branch to
+true. And then a 'static_key_slow_dec()', will again make the branch false.
+
+An example usage in the kernel is the implementation of tracepoints:
+
+ static inline void trace_##name(proto) \
+ { \
+ if (static_key_false(&__tracepoint_##name.key)) \
+ __DO_TRACE(&__tracepoint_##name, \
+ TP_PROTO(data_proto), \
+ TP_ARGS(data_args), \
+ TP_CONDITION(cond)); \
+ }
+
+Tracepoints are disabled by default, and can be placed in performance critical
+pieces of the kernel. Thus, by using a static key, the tracepoints can have
+absolutely minimal impact when not in use.
+
+
+4) Architecture level code patching interface, 'jump labels'
+
+
+There are a few functions and macros that architectures must implement in order
+to take advantage of this optimization. If there is no architecture support, we
+simply fall back to a traditional, load, test, and jump sequence.

+5) Static keys / jump label analysis, results (x86_64):
+
+
+As an example, let's add the following branch to 'getppid()', such that the
+system call now looks like:
+
+SYSCALL_DEFINE0(getppid)
+{
+ int pid;
+
++ if (static_key_false(&key))
++ printk("I am the true branch\n");
+
+ rcu_read_lock();
+ pid = task_tgid_vnr(rcu_dereference(current->real_parent));
+ rcu_read_unlock();
+
+ return pid;
+}
+
+The resulting instructions with jump labels generated by GCC is:
+
+ffffffff81044290 <sys_getppid>:
+ffffffff81044290: 55 push %rbp
+ffffffff81044291: 48 89 e5 mov %rsp,%rbp

+
+Without the jump label optimization it looks like:

+ffffffff810441f0: 8b 05 8a 52 d8 00 mov 0xd8528a(%rip),%eax # ffffffff81dc9480 <key>

+
+Thus, the disable jump label case adds a 'mov', 'test' and 'jne' instruction
+vs. the jump label case just has a 'no-op' or 'jmp 0'. (The jmp 0, is patched
+to a 5 byte atomic no-op instruction at boot-time.) Thus, the disabled jump
+label case adds:
+
+6 (mov) + 2 (test) + 2 (jne) = 10 - 5 (5 byte jump 0) = 5 addition bytes.
+
+If we then include the padding bytes, the jump label code saves, 16 total bytes
+of instruction memory for this small fucntion. In this case the non-jump label
+function is 80 bytes long. Thus, we have have saved 20% of the instruction
+footprint. We can in fact improve this even further, since the 5-byte no-op
+really can be a 2-byte no-op since we can reach the branch with a 2-byte jmp.
+However, we have not yet implemented optimal no-op sizes (they are currently
+hard-coded).
+
+Since there are a number of static key API uses in the scheduler paths,
+'pipe-test' (also known as 'perf bench sched pipe') can be used to show the
+performance improvement. Testing done on 3.3.0-rc2:

+Samsung S5P/EXYNOS4 FIMC driver
+
+Copyright (C) 2012 Samsung Electronics Co., Ltd.
+---------------------------------------------------------------------------
+
+The FIMC (Fully Interactive Mobile Camera) device available in Samsung
+SoC Application Processors is an integrated camera host interface, color
+space converter, image resizer and rotator. It's also capable of capturing
+data from LCD controller (FIMD) through the SoC internal writeback data
+path. There are multiple FIMC instances in the SoCs (up to 4), having
+slightly different capabilities, like pixel alignment constraints, rotator
+availability, LCD writeback support, etc. The driver is located at
+drivers/media/video/s5p-fimc directory.
+
+1. Supported SoCs
+=================
+
+S5PC100 (mem-to-mem only), S5PV210, EXYNOS4210
+
+2. Supported features
+=====================
+
+ - camera parallel interface capture (ITU-R.BT601/565);
+ - camera serial interface capture (MIPI-CSI2);
+ - memory-to-memory processing (color space conversion, scaling, mirror
+ and rotation);
+ - dynamic pipeline re-configuration at runtime (re-attachment of any FIMC
+ instance to any parallel video input or any MIPI-CSI front-end);
+ - runtime PM and system wide suspend/resume
+
+Not currently supported:
+ - LCD writeback input
+ - per frame clock gating (mem-to-mem)
+
+3. Files partitioning

+ drivers/media/video/s5p-fimc/regs-fimc.h
+
+4. User space interfaces
+========================
+
+4.1. Media device interface
+
+The driver supports Media Controller API as defined at
+http://http://linuxtv.org/downloads/v4l-dvb-apis/media_common.html
+The media device driver name is "SAMSUNG S5P FIMC".
+
+The purpose of this interface is to allow changing assignment of FIMC instances
+to the SoC peripheral camera input at runtime and optionally to control internal
+connections of the MIPI-CSIS device(s) to the FIMC entities.
+
+The media device interface allows to configure the SoC for capturing image
+data from the sensor through more than one FIMC instance (e.g. for simultaneous
+viewfinder and still capture setup).
+Reconfiguration is done by enabling/disabling media links created by the driver
+during initialization. The internal device topology can be easily discovered
+through media entity and links enumeration.
+
+4.2. Memory-to-memory video node
+
+V4L2 memory-to-memory interface at /dev/video? device node. This is standalone
+video device, it has no media pads. However please note the mem-to-mem and
+capture video node operation on same FIMC instance is not allowed. The driver
+detects such cases but the applications should prevent them to avoid an
+undefined behaviour.
+
+4.3. Capture video node
+
+The driver supports V4L2 Video Capture Interface as defined at:
+http://linuxtv.org/downloads/v4l-dvb-apis/devices.html
+
+At the capture and mem-to-mem video nodes only the multi-planar API is
+supported. For more details see:
+http://linuxtv.org/downloads/v4l-dvb-apis/planar-apis.html
+
+4.4. Camera capture subdevs
+
+Each FIMC instance exports a sub-device node (/dev/v4l-subdev?), a sub-device
+node is also created per each available and enabled at the platform level
+MIPI-CSI receiver device (currently up to two).
+
+4.5. sysfs
+
+In order to enable more precise camera pipeline control through the sub-device
+API the driver creates a sysfs entry associated with "s5p-fimc-md" platform
+device. The entry path is: /sys/platform/devices/s5p-fimc-md/subdev_conf_mode.
+
+In typical use case there could be a following capture pipeline configuration:
+sensor subdev -> mipi-csi subdev -> fimc subdev -> video node
+
+When we configure these devices through sub-device API at user space, the
+configuration flow must be from left to right, and the video node is
+configured as last one.
+When we don't use sub-device user space API the whole configuration of all
+devices belonging to the pipeline is done at the video node driver.
+The sysfs entry allows to instruct the capture node driver not to configure
+the sub-devices (format, crop), to avoid resetting the subdevs' configuration
+when the last configuration steps at the video node is performed.
+
+For full sub-device control support (subdevs configured at user space before
+starting streaming):
+# echo "sub-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode
+
+For V4L2 video node control only (subdevs configured internally by the host
+driver):
+# echo "vid-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode
+This is a default option.
+
+5. Device mapping to video and subdev device nodes
+==================================================
+
+There are associated two video device nodes with each device instance in
+hardware - video capture and mem-to-mem and additionally a subdev node for
+more precise FIMC capture subsystem control. In addition a separate v4l2
+sub-device node is created per each MIPI-CSIS device.
+
+How to find out which /dev/video? or /dev/v4l-subdev? is assigned to which

+
+6. Platform support
+===================
+
+The machine code (plat-s5p and arch/arm/mach-*) must select following options
+
+CONFIG_S5P_DEV_FIMC0 mandatory
+CONFIG_S5P_DEV_FIMC1 \
+CONFIG_S5P_DEV_FIMC2 | optional
+CONFIG_S5P_DEV_FIMC3 |
+CONFIG_S5P_SETUP_FIMC /
+CONFIG_S5P_SETUP_MIPIPHY \
+CONFIG_S5P_DEV_CSIS0 | optional for MIPI-CSI interface
+CONFIG_S5P_DEV_CSIS1 /
+
+Except that, relevant s5p_device_fimc? should be registered in the machine code
+in addition to a "s5p-fimc-md" platform device to which the media device driver
+is bound. The "s5p-fimc-md" device instance is required even if only mem-to-mem
+operation is used.
+
+The description of sensor(s) attached to FIMC/MIPI-CSIS camera inputs should be
+passed as the "s5p-fimc-md" device platform_data. The platform data structure
+is defined in file include/media/s5p_fimc.h.
+
+7. Build
+========
+
+This driver depends on following config options:
+PLAT_S5P,
+PM_RUNTIME,
+I2C,
+REGULATOR,
+VIDEO_V4L2_SUBDEV_API,
+
+If the driver is built as a loadable kernel module (CONFIG_VIDEO_SAMSUNG_S5P_FIMC=m)
+two modules are created (in addition to the core v4l2 modules): s5p-fimc.ko and
+optional s5p-csis.ko (MIPI-CSI receiver subdev).

- If it is detected that the compiler has support for "asm goto",

- be converted to a jump to the trace function. This technique

- On i386, options added to the compiler flags may increase
- the size of the kernel slightly.
+ Certain performance-sensitive kernel code, such as trace points,
+ scheduler functionality, networking code and KVM have such

+ If it is detected that the compiler has support for "asm goto",
+ the kernel will compile such branches with just a nop

+ * 06-May-1997 RMK Added blacklist for cards whose loader doesn't work.
