With PREEMPT_RT and HIGHMEM on ppc32 (8572ds eval board), there is a
lot of coredumps (data access, 0x300) very early in the boot
process. There is no problem when using only one of PREEMPT_RT or
HIGHMEM.
I also tried rt1 and rt7 and it's the same behavior.

After a 1.5 years sabbatical from preempt-rt we are pleased to
announce a refactored preempt-rt patch against linux-2.6.29-rc4.
The patch is working on x86 (32 and 64bit) but we have not yet updated
ARM, PPC and MIPS (work in progress).
We also dropped some experimental features of the base preempt-rt
queue 2.6.26.8-rt15 simply because we wanted to survive the forward
port over 3 kernel releases with the least amount of surprises. These
features (e.g. multiple reader PI locks) are not essential for the
preempt-rt functionality and need some serious overhaul anyway.
The interested -rt observer might have noticed that we based our work
on the 2.6.26.8-rt15 patch queue and did not pick the git-rt tree
which is based on 2.6.28. The reason for this is that we wanted to pick
the most stable patch queue and the git-rt tree has a lot of rewritten
new code. Our work is not making the work which was done over the last
months in the git-rt tree obsolete, quite the contrary: we want to
provide a stable yet latest-kernel based foundation and integrate those
changes gradually, as they become ready.
The further plan for the new -rt series is to merge it fully into git
and integrate it into the -tip git tree so it gets the same treatment
as all of our -tip based work: fully automated compile and boot
testing. Furthermore an automated multi architecture -rt performance
regression test based on the same infrastructure is currently being
built.
The integration into the -tip tree also allows us to seperate out parts
of -rt which are ready for mainline more easily and integrate them
with our usual propagation to mainline.
The structure of the patches is likely to change over the next days
when we tackle the git integration, but we appreciate your feedback in
the form of comments, bugreports and patches.
Enough said. You can find the new patches at the following location:

We are pleased to announce the next update to our new preempt-rt
series.
- port forward to 2.6.29-rc8
- disable -rt conflicting config options
- hotplug cpu fixes (peterz)
- slab/pagealloc lock breaks (peterz / tglx)
- sigqueue caching for -rt tasks
- posixtimer thread avoid useless wakeups
- various build fixes (mingo, frank ....)
- lots of tracer updates from -tip (check the tip git logs)
The outstanding improvement is the slab/pagealloc change which breaks
and splits locking and brought down worst case latencies in
problematic use cases from >500us to <100us.
As a side note:
There seems to be a wide spread underestimation of the problem spots
exposed by preempt-rt. The usual shrug off answer is:
"I don't care about -rt. Come back if you can expose the same
problem in the mainline kernel."
This is a fundamentally wrong answer.
preempt-rt mostly exposes existing latency spots and magnifies
them
Reducing latencies in -rt by a factor 5 will be not that
prominent in a non-rt setup, but the problematic code area
will still produce measureable latency problems.
I'm well aware of the tradeoff between determinitic behaviour and
throughput, but problematic spots (e.g. lock contentions) hurt
both.
So can we please put down the stupid "I don't care about -rt"
attitudes and accept that we have to think about the mutual
benefits of deterministic and throughput aspects without hurting
each other ?

We are pleased to announce the next update to our new preempt-rt
series.
- resurrected ARM and PowerPC support
- tracing fixes for ARM (Uwe Kleine-Koenig)
The support for ARM/PowerPC has only been lightly tested. It might
crash and burn your system, make your hair curl, frigthen your cat and
give you sleepless nights. You have been warned !
On PowerPC watch out for the following warning:
__do_IRQ called for irq X. PREEMPT_RT will crash your system soon.
__do_IRQ is deprecated and -rt does not support it anymore. Most of
the PowerPC subarchitectures do not longer use it, but you might be
unlucky and hit one of the remaining users. RT will spit out the
message above and then do what it said. :)

We are pleased to announce the next update to our new preempt-rt
series.
- fix a fork/exit bug in the signal per task cache (/me puts on
a huge brown paper bag - Thanks to Phillipe Reynes and Will
Schmidt for reporting and testing)
- fix a group scheduling migration accounting bug (decoded with
and fixed by Peter Zijlstra - reported by Robin Gareus)
- tlb gather rework by Peter Zijlstra - Thanks Peter !
- the usual fixlets
The tlb rework might be incomplete on some of the uncountable
incarnations of PowerPC and ARM platforms, so look out for wreckage
and keep the usual tools (fire-extinguishers, brooms, buckets etc.)
handy.

We are pleased to announce the next update to our new preempt-rt
series.
- include the futex rework + requeue_pi support (Darren Hart)
The futex changes need profound testing. As we know from prior futex
work the best stress tests for the futex interface are RT-Java-VMs
especially with enterprise work loads on larger machines. Can the
folks who have access to such monstrosities please unleash the beasts
and give the futex code a good work out ? Please tell your sysadmin
upfront that he should be stand by to fix up the resulting wreckage
which might vary from harmless to system replacement.
Unfortunately I was not able to track down the weird 32bit PAE
shutdown crash, so the affected users need to stick to the
nosmp-alternatives work around for now.
