| CHANGES since 0.99 patchlevel 15: |
| |
| - removed all the bugs, of course. |
| - networking fixes. |
| - more changes than I really wanted.. |
| |
| CHANGES since 0.99 patchlevel 14: |
| |
| - too many to count, really. Besides, I've lost my notes. |
| |
| CHANGES since 0.99 patchlevel 13: |
| |
| - new kernel source layout: drivers separated |
| - lots of networking bugs fixed, and new network card drivers (Alan Cox, |
| Donald Becker &co) |
| - sound driver added to the default source distribution (Hannu |
| Savolainen) |
| - updated SCSI driver code (Eric Youngdale, Drew Eckhardt &co) |
| - readonly OS/2 filesystem support (HPFS) added (Chris Smith) |
| - NTP support (Philip Gladstone, Torsten Duwe, ??) |
| - fixed 16MB swap-area limit |
| - lots of minor cleanups, buxfixes etc. |
| |
| CHANGES since 0.99 patchlevel 12 and earlier: |
| |
| - the bad memory management one-liner bug in pl12 is naturally fixed. |
| - compiled with plain C by default instead of C++ |
| - ELF binary support (Eric Youngdale) |
| - Quickport mouse support (and some changes to the PS/2 mouse driver) |
| by Johan Myreen and co) |
| - core file name change ("core" -> "core.xxxx" where xxxx is the name |
| of the program that dumped code). Idea from ???. Also, core-files |
| now correctly truncate any existing core file before being written. |
| - some mmap() fixes: better error returns, and handling of non-fixed |
| maps for /dev/mem etc. |
| - one kludgy way to fix the wrong arp packets that have plagued net-2d |
| (resulting in arp packets that had the first four bytes of the |
| ethernet address as the IP address). |
| - I fixed the mount-point handling of 'rename()' and 'unlink()/rmdir()' |
| so that they should now work and/or give appropriate error messages. |
| An early version of this patch was already sent to the KERNEL |
| channel, which fixed the rename problem but not a similar bug with |
| unlink. |
| - packet mode fixes by Charles Hedrick. Sadly, these are likely to |
| break old telnet/rlogin binaries, but it had to be done in order to |
| communicate correctly with the rest of the world. |
| - FPU emulator patches from Bill Metzenthen. The fprem1 insn should be |
| correct now (not that anybody seems to have seen the incorrect |
| behaviour..) |
| - a few fixes for SCSI (Drew and Eric) |
| - signal.c changes to handle multiple segments (for Wine) correctly. |
| - updated drivers from Donald Becker: 3c509 and AT1500 drivers, but |
| also some other drivers have been edited, and some networking fixes. |
| |
| CHANGES since 0.99 patchlevel 11 and earlier: |
| |
| - The memory manager cleanup has continued, and seems to be mostly |
| ready, as proven by the ease of adding mmap() over NFS with the new |
| routines. So yes, the pl12 kernel will demand-load your binaries |
| over NFS, sharing code and clean data, as well as running shared |
| libraries over NFS. Memory management by Eric and me, while the NFS |
| mmap code was written by Jon Tombs, |
| |
| - ** IMPORTANT **: The keyboard driver has been enhanced even further, |
| and almost everything is completely re-mappable. This means that |
| there is a new version of 'loadkeys' and 'dumpkeys' that you must use |
| with this kernel or you'll have problems. The default keyboard is |
| still the US mapping, but if you want to create your own mappings |
| you'll have to load them with the new binaries. Get the 'kbd.tar.gz' |
| archive from the same place you get the kernel. |
| |
| The new keymappings allow things like function key string changes, |
| remapping of the control keys, and freedom to remap any of the normal |
| keyboard functions: including special features like rebooting, |
| console switching etc. The keyboard remapping code has been done |
| mostly by Risto Kankkunen (Risto.Kankkunen@Helsinki.FI). |
| |
| - updated network drivers by Donald Becker |
| |
| - updated serial drivers - tytso@Athena.mit.edu |
| |
| - updated 387 emulation (Bill Metzenthen). The updated emulator code |
| has more exact trigonometric functions and improved exception |
| handling. It now behaves very much like a real 486, with only small |
| changes (greater accuracy, slightly different denormal NaN handling |
| etc - hard to detect the differences even if you are looking for |
| them). |
| |
| - network timer fixes by Florian La Roche (much cleaned up net/inet/timer.c |
| and some bad race-conditions fixed). |
| |
| - Scsi code updates by Eric Youngdale and others |
| |
| - Sony CDU-31A CDROM driver by Corey Minyard added to the standard |
| kernel distribution. |
| |
| - The Mitsumi CDROM driver is now part of the standard kernel. Driver |
| by Martin Harriss with patches by stud11@cc4.kuleuven.ac.be (yes, he |
| probably has a real name, but no, I haven't found it) and Jon Tombs. |
| |
| - various other minor patches (preliminary ldt support etc) |
| |
| NOTABLE changes since patchlevel 10 or earlier: |
| |
| - The memory manager has been cleaned up substantially, and mmap() |
| works for MAP_PRIVATE. MAP_SHARED is still not supported for |
| anything else than /dev/mem, but even so it actually is usable for a |
| lot of applications. The shared library routines have been rewritten |
| to use mmap() instead of the old hardcoded behaviour. |
| |
| - The kernel is now compiled with C++ instead of plain C. Very few |
| actual C++ features are used, but even so C++ allows for more |
| type-checking and type-safe linkage. |
| |
| - The filesystem routines have been cleaned up for multiple block |
| sizes. None of the filesystems use it yet, but people are working on |
| it. |
| |
| - named pipes and normal pipes should hopefully have the right select() |
| semantics in the presense/absense of writers. |
| |
| - QIC-02 tape driver by Hennus Bergman |
| |
| - selection patches in the default kernel |
| |
| - fixed a bug in the pty code which led to busy waiting in some |
| circumstances instead of sleeping. |
| |
| - Compressed SLIP support (Charles Hedrick). See net/inet/CONFIG |
| |
| - the 'clear_bit()' function was changed to return the previous setting |
| of the bit instead of the old "error-code". This makes use of the |
| bit operations more logical. |
| |
| - udelay() function for short delays (busy-waiting) added. Used |
| currently only by the QIC driver. |
| |
| - fork() and sheduler changes to make task switches happen only from |
| kernel mode to kernel mode. Cleaner and more portable than the old |
| code which counted on being able to task-switch directly into user |
| mode. |
| |
| - debugging malloc code. |
