| libraw1394 Release Notes |
| |
| Version 2.1.0: |
| - Behavior changes of the backend to firewire-core: |
| - The isochronous reception buffer is now mapped read/writable |
| rather than read-only. The raw1394 backend already maps the |
| buffer read/writable too. Note that writing into the buffer |
| will go wrong on architectures without cache-coherent DMA if |
| the CPU and the OHCI write within the same cacheline region, |
| so use this feature with caution. |
| - Decrease memory footprint of IR and IT buffers by avoiding |
| some internal rounding up of the buffer size. |
| - New APIs in <libraw1394/raw1394.h>: |
| - raw1394_add_config_rom_descriptor(): |
| Add contents to the Configuration ROM of the local node(s). |
| At runtime, this API is only available if running on top of |
| firewire-core. It could probably also be implemented with |
| the raw1394 kernel driver if anybody cared. |
| - raw1394_remove_config_rom_descriptor(): |
| Counterpart to raw1394_add_config_rom_descriptor(). |
| - raw1394_read_cycle_timer_and_clock(): |
| Like the existing raw1394_read_cycle_timer(), but lets the |
| caller choose between CLOCK_REALTIME (which the former call |
| is always using), CLOCK_MONOTONIC, or CLOCK_MONOTONIC_RAW. |
| For example, this enables libffado's audio streaming to run |
| undisturbed by resets of CLOCK_REALTIME. |
| At runtime, this call requires firewire-core underneath. |
| - raw1394_get_speed(): |
| Returns the speed code of the maximum possible transmission |
| speed between a given node and the local node. This takes |
| maximum speeds of all participating PHYs and the two links |
| into account. This can be used to configure the speed of |
| isochronous streams. |
| At runtime, this call requires firewire-core underneath. |
| - enum raw1394_iso_speed was extended by |
| RAW1394_ISO_SPEED_800, _1600, and _3200. |
| - New APIs in <libraw1394/ieee1394.h>: |
| - Added preprocessor constants |
| L1394_SPEED_BETA, L1394_SPEED_800, _1600, and _3200. |
| - testlibraw1394: |
| Added unit tests of the new APIs. |
| |
| Version 2.0.9: |
| - Fix that raw1394_iso_recv_flush() did not have any effect when running |
| on firewire-core alias juju kernel drivers. Requires kernel 3.4 or |
| later. |
| - Remove build-time dependency on linux-headers. Before, if too old |
| kernel headers were present on the build system, features and fixes |
| would be silently omitted from the build. |
| - Remove --with-fw-dir configure switch which is no longer useful. |
| - Janitorial fixes. |
| |
| Version 2.0.8: |
| - Configuration ROM access via raw1394_read() is dramatically faster and |
| very robust now. We read the kernel's Configuration ROM cache instead |
| of the actual register of the FireWire device. |
| - Internally retry raw1394_read/write/lock/lock64() after ack-busy |
| response. Most notably this fixes control of some older Panasonic and |
| Grundig camcorders. |
| - small bug fixes |
| |
| Version 2.0.7: |
| - Fix playback to some audio devices based on the DICE chipset. |
| |
| Version 2.0.6: |
| - Bug fixes, notably for FCP and request reception on firewire-core. |
| Note, several of these updates are only built into libraw1394 if |
| linux-headers 2.6.36 or later are present at build time. |
| |
| Version 2.0.5: |
| - Bug fixes, in particular, for isochronous transmission and FFADO project. |
| |
| Version 2.0.4: |
| - Fix build due to incomplete tarball. |
| |
| Version 2.0.3: |
| - various bug fixes, in particular for firewire stack |
| |
| Version 2.0.2: |
| - Fixed license headers on new files introduced in v2.0.0 to be consistent |
| with LGPL v2.1. |
| |
| Version 2.0.1: |
| - Optimized usage of /dev/fw? nodes based upon user permissions. |
| - many good bugfixes |
| |
| Version 2.0.0: |
| - added support for new firewire subsystem. |
| - removed deprecated isochronous functions. |
| |
| Version 1.3.0: |
| - added raw1394_read_cycle_timer() as used by FFADO project. |
| - added support for environment variable RAW1394DEV to override default |
| device node /dev/raw1394. |
| - added --with-valgrind to configure script. |
| - other optimizations and bugfixes - see ChangeLog. |
| |
| Version 1.2.1: |
| - generate compiler warnings on deprecated functions (legacy isochronous). |
| - bugfixes and optimizations. |
| |
| Version 1.2.0: |
| - added constants useful for ARM: transaction and response return codes. |
| - added raw1394_bandwidth_modify() and raw1394_channel_modify(). |
| |
| Version 1.1.0: |
| - added ability to specify the isochronous receive mode in the new |
| rawiso (raw1394_iso_*) API. Therefore, the signature of |
| raw1394_iso_recv_init() changed, and likewise, the libtool/.so version |
| numbers changed to reflect a new interface that is not backwards compatible! |
| - added raw1394_arm_set_buf() and raw1394_arm_get_buf() functions. |
| - added raw1394_new_handle_on_port() to make initialization simpler. |
| - make versioning consistent and updated. 1.0.0 was reported by pkg-config in |
| 0.10 series; hence, 1.1.0 in this release. |
| - removed outdated, bogus "linking required only" version symbols in |
| version.c - use pkg-config now. |
| - dropped libraw1394.m4 - use pkg-config now. |
| - added RPM spec file. |
| - deprecate old isochronous API. |
| - move API comment documentation to header and reformat header comments as |
| kernel-doc (use linux/scripts/kernel-doc to extract and format them). |
| - updated tools/dumpiso and tools/sendiso to new isochronous API. |
| |
| Version 0.10: |
| |
| - merged in the rawiso branch |
| - add sendiso and dumpiso tools with man files |
| - fix wrong error mapping on local transactions in raw1394_errcode_to_errno(). |
| - added comment headers for most exported functions |
| - merged in weihs branch which brings new functionality including address |
| range mapping, reading and writing configROM images, additional bus reset |
| handling, and others. |
| |
| Version 0.9: |
| |
| - error reporting reworked to be more C library style; functions affected are |
| mainly raw1394_read(), raw1394_write(), raw1394_lock; |
| Source incompatibility! Parts need to be adapted in application code, but |
| it's well worth it. |
| - the generation number is not unconditionally updated on bus reset in the event |
| loop anymore, the new function raw1394_update_generation() has to be used |
| (unless the default bus reset handler is used) so that transactions won't fail |
| - iso handlers used to get the iso header quadlet in host endian, now they get |
| it in big endian like the rest of the packet for consistency |
| - testlibraw gets installed now, man page also included |
| - (not yet complete) documentation in Docbook format included |
| - libraw1394.m4 autoconf macro added |
| |
| Version 0.8: |
| |
| - added libraw1394/ieee1394.h with useful defines (especially ack and rcodes) |
| - function to query isochronous resource manager ID |
| - functions for isochronous sending |
| - new raw1394_reset_bus() function to reset the bus |
| |
| Version 0.7: |
| |
| - added support for environments where the kernel runs in 64 bit mode whereas |
| user space runs in 32 bit mode |
| - fixed lock transaction to actually return the required response; these |
| functions are actually useful now, prototypes for raw1394_start_lock and |
| raw1394_lock changed |
| - a void pointer can now be stored as user data with a handle |
| |
| Version 0.6: |
| |
| - FCP monitoring added |
| - not really libraw1394 news: the subsystem doesn't swap data anymore, |
| everything is to be kept big endian now on all architectures |
| |
| Version 0.5: |
| |
| - there are now separate iso handlers for each channel |
| |
| Version 0.4: |
| |
| - isochronous receive support |
| |
| Version 0.3: |
| |
| - first release of new libraw1394 for new raw1394 driver |
| - supports 1394 async reads/writes |
