linux only has 16-bit wide dev_t. this is apparently going to
change in linux-2.3 but for now we can't handle devices with
major or minor numbers > 255.
handling of empty directory slots has been fixed.

I use some special code when I write to those 64 bit registers.

o New Newport console code.
o New G364 console code.

user would expect it to work, like under IRIX with the exception
that the machine doesn't freeze solid as long as the button is
pressed.
o Realtime clock driver (CONFIG_SGI_DS1286) for the Indy. Includes
/proc/rtc interface which tells you everything about your RTC which
you never wanted to know. You have to configure this driver into
your kernel or you won't be able to set your RTC.
o Some cleanup of the RTC interfaces in Linux, RTC does no longer mean
PC-style RTC. The userland interface definitions are now in
<linux/rtc.h>. We still need some more cleanup until we can enable
several RTC drivers.
o Virtual aliasing fixes for ptrace(2).
o Add ptrace(2) interface definitions needed to build GDB to
<asm/ptrace.h>.
o Revert to some older routines, the newer optimized ones are buggy.
o On panic the Indy LED will be blinking fast crying to the admin
passing by [music from Rocky Horror show] ``fix me, fix me, fix
me''.
o On panic the power button will only reboot the machine, not power it
down. That's probably more what people want it to do.
o Remove some old files.
o Did I tell you that CVS is buggy?

o Cleanup the machine dependencies of floppy and rtc. The driver for
the Dallas thingy in the Indy is still missing.
o Handle allocation of zero'd pages correct for R4000SC / R4400SC.
o Page colouring shit to match the virtual and physical colour of all
mapped pages. This tends to produce extreme fragmentation problems,
so it's deactivated for now. Users of R4000SC / R4400SC may re-enable
the code in arch/mips/mm/init.c by removing the definition of
CONF_GIVE_A_SHIT_ABOUT_COLOURS. Should get them somewhat further -
but don't shake to hard ...
o Fixed ptrace(2)-ing of syscalls, strace is now working again.
o Fix the interrupt forwarding from the keyboard driver to the psaux
driver, PS/2 mice are now working on the Indy. The fix is somewhat
broken as it prevents generic kernels for Indy and machines which handle
things different.
o Things I can't remember.

o Fix ancient bug in the ELF loader making ldd crash.
o Fix ancient bug in the keyboard code for SGI, SNI and Jazz.
|
| |
|
|
|
|
|
|
|
| |
o First round of bugfixes for the SC/MC CPUs.
o FPU context switch fixes.
o Lazy context switches.
o Faster syscalls.
o Removed dead code.
o Shitloads of other things I forgot ...
|
| |
|
|
|
| |
o Divide L1 cache sizes by 1024 before printing, makes the numbers a
bit more credible ...
|
| |
|
|
|
|
|
| |
o New faster syscalls for 2.1.x, too
o Upgrade to 2.1.89.
Don't try to run this. It's flaky as hell. But feel free to debug ...

The new signal code with exception of the code for the rt signals.
The definitions in <asm/siginfo.h> and <asm/ucontext.h> are currently
just stolen from the Alpha and will need to be overhauled.

slap slap slap.
actually return the value of vmalloc.

inode.c: - Formatting, minor change to start supporting indirect extents.
dir.c: - Prevent access to an indirect directory from hosing the system.
*.h: - Add forgotten include files.

Still need to figure out how to do SVR-style clone devices with
fops->open(), and I need a good poll() tutorial. =)
Other than that, I think I know how to do:
/dev/usemaclone open()ing, poll()ing
/dev/usema ioctls:
- UIOCATTACHSEMA
- UIOCBLOCK
- UIOCUNBLOCK
Also, some minor additions to sysirix.c:syssgi().

IMPORTANT NOTE: I could not figure out what information is the
one that should be used for the following files (ie, those
that were in our tree, or those that came from Linus' patch),
please, check these:
include/asm-mips/jazz.h
include/asm-mips/jazzdma.h
include/asm-mips/ioctls.h

- make keyboard forward events to the streams keyboard
module for delivery to the shmiq.
- Fixes to make the graphics streams driver use dentries
(this is the reason Alex's compile failed).
- Major/misc numbers that were assigned by HPA for the
streamable devices.
- keyboard streams device.
- working shmiq framework for the keyboard.
What needs to be done:
- Fix the mouse driver, did someone ever got any
information out from /dev/psaux on the SGI port?
- Figure out why changes made in the kernel side to the
SHMIQ are not always seen by the user space.

interrupt-land and a user application.
Vmalloc is now an inline function that calls vmalloc_prot with
the original protection bits used in vmalloc.
