Re: [patch] voluntary-preempt-2.6.9-rc2-mm1-S1

[Shane Shrybman]

I am having what appears to be IDE DMA problems with 2.6.9-rc2-mm1-S1.
2.6.9-rc2-mm1 does not show this problem and runs fine. Before this I
was happily using 2.6.8-rc3-O5.

I tried booting with acpi=off but was unable to enter my user name at
the login prompt, it just hung with no response to sysreq. I also tried
turning off irq threading for that irq but it made no difference.

There is one drive on the secondary channel of this Promise TX133. This
is what appears in the log after a minute or two of using the drive.

hdg: dma_timer_expiry: dma status == 0x24
PDC202XX: Secondary channel reset.

[..many repeats..]

It sometimes recovers but it immediately happens again. This leaves apps
touching that drive stuck in an un-killable D state and eventually I
have to reboot.

does undoing (patch -R) the attached patch fix this IDE problem?

i'm getting the same problem
(although not sure if the dma status was the same)
if i enable hardirq preemption
turning acpi on/off doesn't change anything
io/up apic is on (haven't tried disabling it)

with hardirq preemption disabled in .config
everything looks fine sofar (~5h )

Re: [patch] voluntary-preempt-2.6.9-rc2-mm1-S1

[Karsten Wiese]

Hi Ingo,

things improved here after having applied 
swapspace-layout-improvements-2.6.9-rc1-bk12-A1.
I'm happily running jackd and clients realtime now without any dropouts even 
under heavy swapping pressure.
(Machine is a PIII@600MHz with 256MB RAM)
Could you please include the swapspace-layout-improvements in the 
voluntary-preempt patches?

The point is to let gettimeofday(0,1) start tracing and
gettimeofday(0,0) stop tracing - a system-call-controlled tracing
facility (if trace_enabled=2). This was used to trace weird latencies
before, but it's not the normal mode of operation.

Ok. The other point is a page_fault being generated later on in 
sys_gettimeofday() if tz is not reset:

yeah - it's a bit ugly. The right thing is to return from that branch.

only if Andrew agrees that the patch has a chance for -mm inclusion and
possible upstream merging.

It needs more work - from the (brief) testing I did, it didn't seem to
improve that which it was intended to improve: swap I/O performance.  Not
sure why, really.

The latency improvements were serendipitous.

[patch] voluntary-preempt-2.6.9-rc1-bk12-R6

[Ingo Molnar]

i've released the -R6 patch:

  http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc1-bk12-R6

Changes in -R6:

 - fixed a CONFIG_SMP + CONFIG_PREEMPT bug that had the potential to
   cause spinlock related lockups. (UP kernels are unaffected.) This bug 
   got introduced in -R5.

2.6.9-rc1-bk12 patching order is:

It doesn't look like it is fully ported to x86_64 systems yet, these
compile errors are easy to move away but the functionality doesn't seem
to be there. Probably why Ingo hasn't added the PREEMPT_VOLUNTARY to the
x86_64 Kconfig even though I saw a few bits of x86_64 code in the patch.

Or am I missing something?

yeah, it probably doesnt compile on anything other than x86 right now.

[patch] voluntary-preempt-2.6.9-rc1-bk12-R7

[Ingo Molnar]

i've ported the VP patch to x64. I havent boot-tested it, but it
compiles cleanly and it might even boot:

  http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc1-bk12-R7

Caveats: normal kernel with PREEMPT, PREEMPT_VOLUNTARY, PREEMPT_SOFTIRQS
and PREEMPT_HARDIRQS disabled should work just fine.

A kernel with PREEMPT=y and PREEMPT_VOLUNTARY=y ought to work too - with
a smaller probability though. PREEMPT_SOFTIRQS=y should be the next step
- this one might work too. (PREEMPT_HARDIRQS=y doesnt do anything on x64
yet, because i havent changed the irq code. I'd like to keep non-x86
changes small, unless a developer picks it up - like it happened for the
ppc and ppc64 port of the VP patch.)

PREEMPT_TIMING=y might work too if the previous ones worked. The most
problematic one is probably LATENCY_TRACE=y - i've added the proper
mcount assembly code but mostly blindly. It does compile.

so please try this kernel on real hw and try to figure out step by step
at which stage in the following order of parameters it breaks:

 PREEMPT=y
 PREEMPT_VOLUNTARY=y
 PREEMPT_SOFTIRQS=y
 PREEMPT_TIMING=y
 LATENCY_TRACE=y

(when enabling a new option in this sequence keep all the previous
options enabled.)

Worst-case it already breaks with all these options disabled - in this
case please double-check whether vanilla -bk12 x64 boots fine with the
same .config.

Best-case it works fine with all options enabled - quite unlikely.

If it breaks it will break early and hard during bootup, so data is
probably not at risk - but be careful nevertheless.

[patch] voluntary-preempt-2.6.9-rc1-bk12-R8

[Ingo Molnar]

test-booted the x64 kernel and found a number of bugs in the x64 port of
the VP patch. I've uploaded -R8 that fixes them:

  http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc1-bk12-R8

NOTE: i tested a (non-modular) 64-bit bzImage on a 32-bit OS (FC2) but
havent booted it on a 64-bit userland yet. But i'd expect 64-bit
userspace to work just fine too.

[patch] voluntary-preempt-2.6.9-rc2-mm1-S1

[Ingo Molnar]

i've released the -S1 VP patch:

  http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc2-mm1-S1

NOTE: this patch is against Andrew's -mm tree and the VP patchset will
stay based on -mm until the merging process has been finished.

to get a 2.6.9-rc2-mm1-VP-S1 kernel, the patching order is:

   http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.8.tar.bz2
 + http://kernel.org/pub/linux/kernel/v2.6/testing/patch-2.6.9-rc2.bz2
 + http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.9-rc2/2.6.9-rc2-mm1/2.6.9-rc2-mm1.bz2
 + http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc2-mm1-S1

Changes relative to -S0:

- lots of merging. A good chunk of the VP patch latency breakers and
  support patches are in -mm already.

- integrated my 'preemptible big kernel lock' patch into VP. This makes 
  all BKL code preemptible while keeping correctness. A new debugging 
  infrastructure has been added to catch code that might use the BKL
  in an unsafe way. If the debugging check triggers it will print 
  messages like:

    using smp_processor_id() in preemptible code: bash/1020

  please report such messages and backtraces to me. Most of the messages 
  i've fixed so far were false positives, but one bug has been caught 
  already via this.

  Also, this BKL patch allowed the removal of two questionable 
  latency breakers: the tty.c and the DRM BKL relaxation hack.

- fixed an SMP hardirq redirection bug - IRQ threads could be bound to 
  multiple CPUs resulting in potentially illegal preemption of hardirq
  contexts.

- temporarily dropped the ppc/ppc64 GENERIC_HARDIRQS changes, they broke
  and i cannot test them.

Reports, comments welcome,

	Ingo

Is anyone else having trouble getting this to build on x86 smp? I am 
getting undefined references to smp_processor_id within most, if not 
all, modules.

I don't know if anything can be done about it, but I get lots of them.

Two separate oopses this morning running that above patch. One appears 
to happen in locks_delete_lock. The log output follows. Unfortunately I 
am not sure what is relevant to the oops and whats not so I am sending 
it all. Also the trace that was generated when this happened can be 
found here:

http://www.cybsft.com/testresults/2.6.9-rc2-mm1-VP-S0/lat_trace22.txt

log output:

http://www.cybsft.com/testresults/2.6.9-rc2-mm1-VP-S0/dump1.txt

The other appears to happen in __posix_lock_file.

Trace here:

http://www.cybsft.com/testresults/2.6.9-rc2-mm1-VP-S0/lat_trace23.txt

log output here:

http://www.cybsft.com/testresults/2.6.9-rc2-mm1-VP-S0/dump2.txt

If there is anything else that I can provide on these, or if there is a 
better way to post this, please let me know.

i too got this one today. Seems to be related to the BKL changes -
locks.c is a heavy user of the BKL. You have an SMP system, right? Does
the oops happen if you boot with maxcpus=1?

This was on my SMP system. I can try the maxcpus=1. However, the trouble 
may be reproducing the oops. This happened at ~5:35 this morning (~9 
hrs. ago). Hadn't happened again as of an hour ago when I booted S2. I 
will give it a try though.
