(Did I mention that CVS is buggy ...)

o Implement handlers for VCEI / VCED exceptions. Install them only on
SC / MC versions of the R4000 and R4400 which saves us four
instructions per exception on other CPUs.
o Print the number of VCED / VCEI exceptions in /proc/cpuinfo, iff
available.
o Many performance fixes for the SC / MC versions of R4000 and R4400.

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.

Thanks for the docs, Ariel!

Mark's description of the problem:
This patch seems to have fixed the excessive ethernet timeouts
I've been seeing. The problem was a race condition when queueing
another packet for transmisson. The code in sgiseeq_start_xmit()
would try to start another transmission from the head of the
transmit queue if the HPC was inactive. Because interrupts are
off at this time, it was possible that that packet had been
transmitted but the queue head had not been advanced by an
interrupt service. This resulted in a duplicate packet being
sent over the wire and when interrupts were reenabled, the
normal ack'ing of the original transmission of that packet
would put the HPC into a wedged state which eventually led to
a timeout and reset.

bumped up version number to 0.50
