[patch] Real-Time Preemption, -RT-2.6.12-rc5-V0.7.47-10

[Ingo Molnar]

i have released the -V0.7.47-10 Real-Time Preemption patch, which can be 
downloaded from the usual place:

    http://redhat.com/~mingo/realtime-preempt/

Changes:

 - posix-timer fixes (George Anzinger )

 - RPC timers fix (John Cooper)

 - x64 build fix (Will Dyson)

to build a -V0.7.47-10 tree, the following patches have to be applied:

   http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.11.tar.bz2
   http://kernel.org/pub/linux/kernel/v2.6/testing/patch-2.6.12-rc5.bz2

Since plain 2.6.12-rc5 will not build here, IPMI problems, does this 
include the IPMI patches that will let it build here?

Or is this fix now included in the 2 snapshots with the .git suffix I 
see there in the 2.6/snapshots directory and I should apply them 
prior to the RT patch?

I tried to compile -V0.7.47-15 and it fails to compile.

It seems the following hunk of the patch is bogus as it removes a 
required define:

Have you tried loading and using some of these modules with older -RT 
kernels? If they have been using init_MUTEX_LOCKED on RT semaphores, 
they should have BUG & Oops. Recent -RT kernels have added extra check 
for this during linking. The fact that you are prevented from building 
these modules is a Good Thing(TM).
Maybe these drivers should be using completions instead of semaphores.
A quick fix would be changing the 'struct semaphore' to 'struct 
compat_semaphore'.

I had no such error, applying the 
realtime-preempt-2.6.12-rc5-V0.7.47-15 patch to rc5-git5 (other than 
the Makefile, easily fixed, and lib/Kconfig.debug, as git5 had 
already played with the location of the frame pointers option.  I 
left it at the git5 level, seemed to work.  Its built, but not 
rebooted to, working on wedding photo's for the neighbors ATM.

I used the "linux-2.6.12-rc5-git5-RT-V0.7.47-15" throughout _my_ 
scripts and the Makefile as the version number.  I note your error 
messages seem to indicate a miss-match there.

So many thanks to the original poster, whose message prompted me to 
take another swing at it.

Ingo:

I had little problem in applying this patch to 2.6.12-rc5-git5 after 
deleting those 10 or so bogus lines, the only real failure being the 
Makefile, easily fixed.

I took the defaults for all the new stuff in a make oldconfig started 
with the .config from rc5-git5.

I've rebooted to it & it generally feels good, but the missus came in 
just now and said something about the video quality of my home tv 
channel, and I found that I do not have video from tvtime now, only 
audio, and a very noisey messages log when tvtime is running (git5 by 
itself ran tvtime ok), plus a lot of output on the VT that started 
boinc & einstein@home, something about a memory being exceeded.  But 
its at 1 second intervals and not copy/pastable across a ctl+alt+F1 
to ctl+alt+F7 switch.

That I've stopped & restarted from an xwindow, hopeing the messages 
will repeat shortly.

Ah, heres one:
2005-05-31 12:12:13 [Einstein@Home] result 
H1_1262.4__1262.8_0.1_T00_Test02_3: memory usage 125263872.000000 
exceeds limit 70000000.000000

Which, due to the decimal display format, makes zip sense to me.  I've 
stopped it.

.config, pieces of logs available for the asking.
