Real-Time Preemption, -RT-2.6.12-rc4-V0.7.47-06

i have released the -V0.7.47-06 Real-Time Preemption patch, which can be downloaded from the usual place:

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

there was more stabilization activity during the past couple of weeks - i think i have all pending patches applied, let me know if something went MIA. I've also applied Mingming's ext3 reservation latency reductions.

Changes:

- more plist fixes (Daniel Walker)

- SMP global-RT-reschedule fix (Steven Rostedt)

- x86_64 fixes - it builds & boots now (Joe King)

- ext3 reservations latency reductions (Mingming Cao)

- kstopmachine yield() fixes (Steven Rostedt)

- ksoftirqd init fix (George Anzinger)

- removed yield() uses from coredumping (suggested by many)

to build a -V0.7.47-06 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-rc4.bz2

Ingo,

This one oopses on my dual P4 Xeon system before getting booted. I will dig into this when I get a free minute. I am knee deep in different alligators at the moment.

Ingo,

I did finally get to capture the log of -RT-2.6.12-rc4-V0.7.47-08 dying when booting. I have attached the log and the config. This is on dual 2.6G Xeon with ht and smp enabled, 512M and IDE. What else can I do (in between alligators)? Output from lspci:

hm, i have tried your .config on similar hardware and it doesnt crash.

does it crash if you boot only with a single CPU (numcpus=1 boot parameter)? If yes then could you send me that log, some of the more interesting portions of the current log were garbled due to SMP logging effects.

Ingo

maxcpus=1 is the parameter.

Ingo

No it doesn't crash if I boot only a single CPU. I'll go one better than that. It doesn't crash if I boot both CPUs but without hyper-threading (turned off in the bios but still enabled in the config). :-(

   kr

hm, must be some race. I tried it on a HT system too - will try on another HT system.

can you work it around (or turn it into another type of crash) by disabling STOP_MACHINE? (you can do that by turning off MODULE_UNLOAD)

Ingo

Working on it.

   kr

OK. Unfortunately with MODULE_UNLOAD not set, I can't seem to make it crash. :-/

   kr

cannot reproduce it on my other HT system either. Do you see the same crash with the latest, -rc5 based release too? Maybe we'll get a better crashlog under that kernel.

Ingo

Will give it a spin when I get to the office in a couple of hours.

   kr

This one seems to be fine, or at least it has gotten harder produce the problem. ;-) It is running fine on both of my dual systems currently and should know soon on one of the uni's.

   kr

Hi Ingo,

I'm now running -RT-2.6.12-rc4-V0.7.47-08 on amd64.
I use cpufreq, but with the RT kernel it triggers "Kernel BUG at "kernel/latency.c":1295" (the check for preempt_count underflow).

I'm attaching a patch which changes a semaphore in cpufreq into a completion. With this patch, my system runs OK even with cpufreqd.

Michal

Although the patch worked for me, it was probably bogus. The real reason why cpufreq caused problems was that it does:
init_MUTEX_LOCKED(&policy->lock);
and later:
up(&policy->lock);
where policy->lock is declared as:
struct semaphore lock;

In PREEMPT_RT, the init_MUTEX_LOCKED is defined in include/linux/rt_lock.h :
/*
* No locked initialization for RT semaphores:
*/
#define init_MUTEX_LOCKED(sem) compat_init_MUTEX_LOCKED(sem)
(BTW, I don't understand why we have init_MUTEX but no init_MUTEX_LOCKED for RT semaphores).

Therefore we have an inconsistency - the up() gets translated into rt_up() because the lock is of type struct semaphore. However, compat_init_MUTEX_LOCKED assumes that it has a struct compat_semaphore. The compiler actually warns about incompatible pointers but I missed that warning at first.
So the fix is to change the lock type into compat_semaphore. I'm attaching the patch. It works for me with 2.6.12-rc5-RT-V0.7.47-12.

no, it was quite fine i think.

RT semaphores have stricter semantics than Linux semaphores. One property is that there always needs to be an owner of a semaphore. If a semaphore gets initialized as init_MUTEX_LOCKED, it is a fair indication that the semaphore is really used as a completion object - with no stable owner. (e.g. at insmod time when the init_MUTEX_LOCKED is done, the insmod thread will go away after some time, leaving the semaphore 'orphaned')

it would be nice to get the conversion to completions upstream. It is a perfectly fine solution. The compat_semaphore thing is another, easier solution.

Ingo

Thanks for the explanation. In that case calling init_MUTEX_LOCKED on an RT semaphore is obviously wrong.
However, it only produces a warning during the compilation and is guaranteed to BUG when run. It would be better if it obviously failed to compile. How about the attached patch? That makes the compilation fail like this:

agreed - i've added your patch to my tree.

Ingo

with a small modification: i turned the error into a link-time error, because gcc parses both branches and will give a compiler-time warning even if the proper compat_semaphore is used.

Ingo

Oh, sorry. I actually had it produce a link-time error at first. But I wanted so much to make it fail at compile time that I screwed it up and didn't test both cases.

However, what you have in RT-V0.7.47-13 is still not correct. Now it again produces only a warning :-)
Patch attached. This time I really tested it in both cases. For struct semaphore it fails at link-time. For struct compat_semaphore it compiles without problems.

ok - released -14 with this fix.

Ingo

Replace
init_MUTEX_LOCKED(&policy->lock);
with
init_MUTEX(&policy->lock);
down(&policy->lock);

Compiles here... Would also work upstream.

init_MUTEX_LOCKED() isn't very nice :-(

Esben

btw., could you please submit this upstream too, so that it doesnt get lost? Semaphore->completion conversions are desirable upstream for cases where the semaphore was in reality not used for mutual exclusion but for completion purposes. (in which case real completions are both more readable and slightly faster)

Ingo

Yes, I'm going to contact upstream about this.
However, after closer look on cpufreq code I came to a conclusion that the lock there doesn't really play the role of a completion. There's always: down(), then do something with the data structure, then up() in the same function. I'm going to fix it differently after consulting with upstream author (I now think that it should not be necessary to take the lock in cpufreq_add_dev at all).

Michal

yeah. It would lead to incorrect code to use a completion if the purpose is a real lock. The main non-PREEMPT_RT-compatible use of semaphores is the unlocking of a semaphore the task did not lock itself. It is correct Linux code, so that alone is not a good reason to change upstream (and upstream doesnt and shouldnt bother about PREEMPT_RT at this point) - but if the underlying code is not entirely clean and the cross-owner-use of locks is not justified it might be possible to solve this via a cleanup.

Ingo
