i have released the -V0.7.48-00 Real-Time Preemption patch, which can be
downloaded from the usual place:
http://redhat.com/~mingo/realtime-preempt/
this release includes an improved version of Daniel Walker's soft
irq-flag (hardirq-disable removal) feature. It is an unconditional part
of the PREEMPT_RT preemption model - other preemption models should not
be affected that much (besides possible build issues). Non-x86 arches
wont build. Some regressions might happen, so take care..
Changes since -47-29:
- soft IRQ flag support (Daniel Walker)
- fix race in usbnet.c (Eugeny S. Mints)
- further improvements to the soft IRQ flag code
to build a -V0.7.48-00 tree, the following patches should 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-rc6.bz2

The build fails with inconsistent kallsyms data:
...
LD .tmp_vmlinux1
KSYM .tmp_kallsyms1.S
AS .tmp_kallsyms1.o
LD .tmp_vmlinux2
KSYM .tmp_kallsyms2.S
AS .tmp_kallsyms2.o
LD vmlinux
SYSMAP System.map
SYSMAP .tmp_System.map
Inconsistent kallsyms data
Try setting CONFIG_KALLSYMS_EXTRA_PASS
make: *** [vmlinux] Error 1
When I enable the workaround CONFIG_KALLSYMS_EXTRA_PASS, it works.
This is on i386, Debian Sarge. I'm attaching my .config.

With -V0.7.48-01 I get interestingly long latency traces. For example
this one is 277 us. This is on i386. I've put the full trace to:
http://www.uamt.feec.vutbr.cz/rizeni/pom/latency_trace-RT-V0.7.48-01.txt
Because of the presence of __wake_up_sync there, I'd guess it has
something to do with the NEED_RESCHED_DELAYED thing.
Here's an excerpt of it:

This is probably just bad luck and a known problem that I'm trying to
fix (but hadn't have much time lately).
Can you try to change the line:
#define WORKING_SET 1024
in scripts/kallsyms.c to:
#define WORKING_SET 65536
and disable CONFIG_KALLSYMS_EXTRA_PASS, to see if the problem goes away?
It it does go away, then it is the same problem, and I'm working on it...

Not the same problem. The significant difference in the maps is :-

__sched_text_start has moved up by 1 byte between pass 1 and 2. Text
addresses are not allowed to move between kallsyms passes, kallsyms
only adds data, it never touches the text segment. Paulo's change to
the working set hides this peculiarity, rather than fixing the real
cause. This looks like a toolchain bug, it is moving symbols for no
good reason.

Ingo,
I can't get any version of RT-preempt applied to 2.6.12-rc6 up to and
including 48-01 to boot on any of my SMP systems. I get no log because
it dies right after the "Uncompressing kernel" message. 2.6.12-rc6 boots
fine. I am attaching my config. Am I missing something obvious? I am
building 48-01 with voluntary-preempt now to try that.

Actually this is exactly the same problem we've seen in other threads:
the symbol that marks the beggining of a section gets aligned to a
different boundary on the second pass. Because it has now the same
address as the next symbol, it gets sorted in reverse order.
I agree that this is the toolchain's fault, but I think kallsyms could
be a little more robust and handle this without preventing the kernel
from building properly.

Well crap. Perhaps I should have tried this first. If I disable the
runtime selectable locking
# CONFIG_DEBUG_RT_LOCKING_MODE is not set
it seems to work fine. With the above enabled it hangs on both of my SMP
systems as described above. :-/

Hi,
I've made the soft IRQ flag feature work on x86_64. It compiles and
boots for me.
Attached is the patch against -RT-2.6.12-rc6-V0.7.48-01.

What are these lines fixing again ? It seems rather odd that locking and
then unlocking a mutex could fix anything ..

Same problem here. OK unsetting the CONFIG_DEBUG_RT_LOCKING_MODE.
I have another problem :
I can't boot.
With 47-15 I had the following with dmesg :

found the bug - it was the incorrect initialization of
debug_slock/rwlock. I've uploaded -48-02 with the fix. This release also
includes a new debugging feature: CONFIG_DETECT_SOFTLOCKUP, which works
similar to the NMI watchdog but detects soft (==no reschedules) lockups.
I've also converted a few more local_irq_*() calls to raw_local_irq_*()
calls.

this one should be fixed in the latest patch. (note that when
DEBUG_RT_LOCKING_MODE is set the spinlocks/rwlocks default to
non-preemptible. You can set preemption it via
/proc/sys/kernel/preempt_locks. You normally dont want to enable this
option.)

could you try the latest (-48-03) patch? I fixed a couple of things that
might impact SMP booting.

a freeze is always a problem, whether it can be worked around via a
CONFIG parameter or not. Generally if you see any reduction in
functionality that deviates from the stock Linux kernel, it's a bug.

The attached patch against V0.7.48-04 replaces some more local_irq_*
operation with their raw variants on x86_64. It should be the equivalent
of your changes done for i386 in -V0.7.48-02.

It works great with rc6 without RT patch.

Hi Ingo,
Since the introduction of the delayed preemption feature in V0.7.47-20
my KDE desktop has been jerky. The sound from artsd often skips. The
mouse pointer jumps when I compile anything the background and try to
browse the web with Firefox.
I think that try_to_wake_up is broken for the !sync case. We have:
__activate_task(p, rq);
if (TASK_PREEMPTS_CURR(p, rq)) {
if (sync)
set_tsk_need_resched_delayed(rq->curr);
else
resched_task(rq->curr);
}
Shouldn't we call the full activate_task(...) instead of
__activate_task(...) in the !sync case?
The attached patch fixes seems to fix it for me. It is against V0.7.48-05.

Does latency tracing work correctly?
After leaving my labtop "working" all night I see the /proc/latency_trace
below. It doesn't look right. Normally the worst case latency is ~70 us
but this tells me it is 1.1ms!! Looking at the trace it looks like it was
really just < 70 us and just an error in the trace. It does look like 3
irq-off periods have been merged into one long period overestimating the
worst case latency by a huge factor.

Sorry for not reporting back sooner on this, I just kept getting
interrupted. My problems seem to be resolved on my SMP systems, even when
CONFIG_DEBUG_RT_LOCKING_MODE=y
I should note that I didn't actually try with the version above because
it had been updated before I got to it.

thanks, applied - but this does not end all of the reschedule problems
that the latest patches have. More on that later.

one problem was that the WORK_MASK definitions in thread_info.h were not
updated - neither the word-sized tests in entry.S. This meant we missed
delayed-preemption on return-from-kernel. But we've got one free bit in
the first by - bit 6, so i moved the DELAYED bit there. Another bug was
that the idle thread did not check for delayed preemption. I fixed these
in the -48-07 patch.

Hi Ingo,
I'm having some difficulty with your latest patches; more specifically
linux-2.6.12-rc6-git4-RT-V0.7.48-10 floods me with BUGs like these:

I gather these are because of:
drivers/usb/code/hcd.c:rh_report_status
static void rh_report_status (unsigned long ptr)
{
struct urb *urb;
struct usb_hcd *hcd;
int length = 0;
unsigned long flags;
urb = (struct urb *) ptr;
local_irq_save (flags);
spin_lock (&urb->lock);
...
}
where local_irq_save() would disable pre-emption while spin_lock(); the
urb->lock is not a raw lock; can sleep.
I'm not well versed in that code; do you have a suggestion?
On another note; X seems to have trouble getting up. It consumes a full
CPU right after mode switching (afaict) without getting any progress.
I'll try and get a nice trace of X using sysrq-t.

does the patch below help?

could this be due to the messages spamming the console?

No, no output at all on my (serial) console. Nor does sysrq work; except
for powerOff which really doesn't help :-|, nor does it work with my
current 'good' kernel 2.6.12-rc5-git4-RT-V0.7.47-12. Also any process
touching the X process hangs along with it. I tried strace, gdb etc..
I'll try some more tomorrow..

Dunno, twasn't there till I looked just now. And it made it past that
little roadblock ok. Gonna be slow, logrotate & updatedb are running
as its just past 4am local. Like any good geek, I had to check my
email when I got up to p. :-)
Yes, it built, and I'm rebooted to it. Feels rather normal so far. A
quick game of klondike lagged for the first 3 or 4 moves but smoothed
right up.
Glitch reports as they develop of course.
Q: Whats the diff between turning on hardirq's in mode 3, and mode 4?

well, "mode 3" is PREEMPT_DESKTOP - normal CONFIG_PREEMPT on the
mainstream kernel. If you turn on hardirq/softirq threading then you can
e.g. chprio your sound IRQ to have better audio latencies. It will cause
runtime overhead though. On "mode 4" (PREEMPT_RT) hardirq/softirq
threading is mandatory (due to the processing model).

I think I see. Do you have a swag as to how much runtime overhead
using softirq's only might cause? My normal seti production is about
7 per day, and it seems to have dropped to about 6 while running the
RT versions.

should be barely measurable for desktop workloads. For servers it might
be significant, depending on the amount of IRQ traffic. For any box
doing less than 2000-3000 irqs/sec it should be very small.

Chuckle, for me that would be a 'mox nix' using the english
spelling. :-) And seti made a liar out of me, it did do 7 units
yesterday.

Humm, I think I hijacked a thread. Anyway, for exercise I just built 48-17,
but had to interrupt the boot & go back to 48-13 as I was drowning in

ok, fixed this one - does -48-19 work for you? (PREEMPT_DESKTOP was
broken by the new split-softirqs code)

Its running apparently ok Ingo, but it fussed during the boot because
CONFIG_LATENCY_TRACE was still on, so my ./makeit script is running
again after turning that off. I'd turned its parent in the xconfig
display off mistakenly figureing that got the child. kconfig
miss-cue?
Rebooted to it, no warnings. Glitch reports as they are found. :-)

Sorry for the delay , I was out of my office.
I tested 48-19 and no more problem.
So, is it useful to test it anymore ?
Do you fix it another way ?

yes, the patch is in 48-19 - no need to do any further testing, thanks.

Ingo,
I just got this soft lock with -RT-2.6.12-rc6-V0.7.48-32 on my dual 2.6G
Xeon W/HT. Not sure what causes it. Just typing away and its like a key
sticks. It keeps printing the same key, even if I use the mouse to
change focus the typing follows the focus, and then it finally hangs.

ah ... accidentaly had debug_direct_keyboard = 1 in kernel/irq/handle.c.
Change it to 0 & recompile, or pick up the -48-33 patch i just uploaded.

I think your putting to many raw_local_irq_disable calls back in .. Are
you planning to do an audit at some point ?

correctness comes first. The softirq code needs to use the raw irq flag,
because direct interrupts (the timer irq) may modify
local_softirq_pending().

I have made a patch renaming
local_irq_disable()
to
rt_preempt_irq_disable()
local_irq_disable() is a macro for rt_preempt_irq_disable() (see below).
I think the latter name is tells you more when considering both PREEMPT_RT
and !PREEMPT_RT
In PREEMPT_RT: It disables preemption and threaded irq handlers.
In !PREEMPT_RT: it disables irqs and preemption and it has something to do
with RT_PREEMPT, so keep your hands off!
Furthermore I have made an option to make all local_irq_disable() stop
compiling (CONFIG_NO_LOCAL_IRQ_DISABLE). local_irq_disable() removes
preemption. We don't want that in PREEMPT_RT. All places where it is used
it ought to be reviewed wrt. RT. When that is done we can replace them
with rt_preempt_irq_disable() or better: a lock. When I get time I'll try
to make a lock type which is spinlock_t in PREEMPT_RT but a local cpu lock
with no spin in !PREEMPT_RT.
I also started on a small document Documentation/rt-locking.txt - you are
welcome to skip it. It is certainly not the best document ever written but
I think someone ought to write some short documentation of the new
locking structure and how people wanting to have PREEMPT_RT and people
only caring about !PREEMPT_RT should behave and still be live in the same
code-tree without being of too much anoyance to each other.

+ About locks in PREEMPT_RT mode
+
+ Esben Nielsen <simlo@phys.au.dk>
+
+ 14 Juny 2005
+
+The goal of PREEMPT_RT option is to make Linux into a determnistic RT system.
+I.e. worst case the latency of any only depends on the tasks running at higher
+priority and hard irqs (see below). If the task, waiting for some external
+event, has the highest priority, the task should be running within a
+deterministic amount of time after the external event has happened. That amount
+of time depends on the hardware, the irq handler delivering the event but
+nothing else.
+
+To obtain this the following has been done:
+
+1) All normal Linux interrupt handlers (hard and soft) run in threads. You can
+add non-threaded interrupt handlers but we then assume you are familiar with
+real-time programming and know the rules.
+
+2) A lot of locks and irq-macros have been redefined to make a lot sections
+in the kernel preemptible. New ones have also been introduced. The new
+locks translates into some old well known lock for !PREEMPT_RT. The following
+table says which translation is going on.
+
+
+!PREEMPT_RT | PREEMPT_RT
+------------------------------------------------------------------------------
+spinlock_t | semaphore
+ Disable interrupts locally and | Fully preemptible mutex with priority
+ spins. | inheritance.
+ |
+rwlock_t | rwlock_t
+ Like spinlock_t but allows many | Fully preemptible mutex. Can be used
+ readers. | recursively. Only 1 reader.
+ |
+local_irq_XX | rt_preempt_irq_XX
+ Disable interrupts locally. | Disables preemption locally. Thus
+ | also disables all normal Linux irq
+ | handlers, which are threaded.
+ |
+raw_spinlock | raw_spinlock
+ Same as spinlock. | Same as spinlock for !PREEMPT_RT
+ |
+raw_local_irq_XX | raw_local_irq_XX
+ Same as local_irq_XX. | Same as local_irq_XX for !PREEMPT_RT
+
+raw_X translates to X when !PREEMPT_RT.
+
+Rules for use:
+If you do only code under !PREEMPT_RT and do not care about real-time don't use
+ raw_*
+ rt_preempt_*
+If you want change code protected with these kind of locks: Change them to the
+corresponding !PREEMPT_RT locks before submitting a patch. People carring
+about real-time will prefer this breakage over getting a system not being
+real-time.
+Use the usual locks as you have always done.
+
+If you want to make stuff under PREEMPT_RT:
+Use rt_preempt_irq_* and raw_* with ONLY around code sections which are
+1) Deterministic in execution time. I.e. no algoritms being O(N), N not a
+constant.
+2) Execution time must be in the order of schedule() or less.
+
+Otherwise use the non-raw versions. Or even better: use a mutex (which by
+tradition is called semaphore although I find that highly missleading!). Even
+!PREEMPT_RT it wont be nice to use a spinlock, but you have to do it if you
+share data with an interrupt handler.
+
+If you want to make non-thread irq-handlers you must use raw_local_irq_XX
+to protect data shared with threads. raw_spin_lock does _not_ protect data
+as it only turns off preemption!!

Ingo,
Having problems with -RT-2.6.12-rc6-V0.7.48-33 booting on my older SMP
system (dual 933). Looking at the log apic.log it indicates a problem
with APIC. noapic.log is a log when I add "noapic" to the boot parameters.

could you uncomment the IO_APIC_CACHE define in
arch/i386/kernel/io_apic.c, and could you uncomment line 1109 in
drivers/ide/ide-io.c - does this fix things? (in apic mode)

Couple of things: 1) I could not find IO_APIC_CACHE anywhere. I could
find IOAPIC_CACHE but the define was not commented in io_apic.c. Also
the BUG_ON at line 1109 in ide-io.c was not commented out either. So I
made the mental leap that you actually meant to comment these out
instead of uncomment them??? That works to get the system booted.
Although I am getting many soft lockups now, minutes after the boot. Log
attached. 2) In my infinite wisdom before :-) I failed to attach my
config as I should have done before. Also, commenting out

hm, do you get actual lockups, or only the messages about them? I.e.
does the system work fine if you [the sounds of careful thinking to get
the word right] disable CONFIG_DETECT_SOFTLOCKUP, or does it lock up
silently?

OK so there really was no mental leap. It was more like a
trip,stumble,roll,grasp :-) I actually discovered the real meaning of
the above after commenting out only one of the above and failed boot.
Only then did it dawn on me what you were trying for. Hence the last
line of my email not being finished.

There doesn't seem to be any actual lockups, just messages. I will try
disabling the above when I get home this evening. Can't get to the
system right now.

Actually see my comment above about the "trip,stumble,roll,grasp" The
line above is the point at which I realized what was going on. :-D

Just had an opportunity to check this. Everything does indeed seem to be
working OK with this disabled. No lock up messages, no perceived problems.

i tweaked the softlockup detector in the last patch a bit (to fix false
positives under very high loads), might have broken it on SMP.

I noticed that -33 seems to have a measurable lifetime, so I did the
edits mentioned in this thread and built it. Running now. Gotcha's
if any, reported later. Preempt Mode=3

I'm not sure what it is I've got here. I just tried to restart boinc,
which hadn't run here in 10 days or so, cause its not housebroken yet
IMO, and got this in the shell I started it from after a failed
connection to berkeley attempt, followed by a repeat access:

Can any sense be made from this? This is 48-33 with the two items

btw., you have this enabled in your config:
CONFIG_DEBUG_RT_LOCKING_MODE=y
this causes old-style spinlocking to be activated by default. I.e. you
dont get most of the benefits of PREEMPT_RT. You can reactivate it via:
echo 1 > /proc/sys/kernel/preempt_locks
but obviously this runtime flag involves some runtime overhead in the
locking code. This .config option is mainly meant to enable the
measurement of the locking overhead of PREEMPT_RT, and to debug boot
problems that might be related to PREEMPT_RT locking. So you'd almost
always want to run with DEBUG_RT_LOCKING_MODE turned off.

yeah - found a bug that could explain the symptoms on your system.
Called softlockup_tick() from the global timer interrupt, instead of the
per-CPU timer interrupt. So on SMP the other CPUs would not see any
softlockup ticks at all, and would incorrectly report soft lockups.
This bug is fixed in the -48-36 patch i just uploaded.

Yes I noticed the softlockup_tick() in some stack traces that I
generated with -48-35 last night. Just downloaded and starting to
compile -48-36. Will report back the results. Also will turn of the
CONFIG_DEBUG_RT_LOCKING_MODE mentioned in your previous mail.
thanks.

-48-36 has been up and running for about 45 minutes now and everything
seems much better. I held off because the soft lock ups didn't seem to
manifest themselves right away.

Ingo,
My Xeon/HT box running -48-33 locked up after being up for three days.
This is better uptime than I've seen on this box since -47-19.
CONFIG_DETECT_SOFTLOCKUP and CONFIG_RT_DEADLOCK_DETECT are enabled.
CONFIG_DEBUG_RT_LOCKING_MODE is disabled.
All of the HPET options are enabled. I noticed your comments about HPET
in the adeos thread. Should I disable HPET if I don't have any specific
need for it?
Fortunately, there were some dumps (all ns83820 tx related) left in the
logs before the machine locked:

Three additional dumps like this one follow at 03:21:51, 04:02:06, and
04:06:26 before the machine locked.
I also regularly see high (>200us) wakeup latencies on the Xeon/HT, which
I don't see on the Athlon or non-HT Xeon systems. Disabling IRQ balancing
doesn't seem to help. It's been a while since the Xeon/HT box has seen a
non-debug kernel, but in the past, that hasn't helped latencies by more
than a few usec.

Running -48-36 on the Xeon/HT box, I lost keyboard and network after a
couple hours. Same .config as was used for -48-33 (attached... forgot to
send in previous email). Xscreensaver was still running with no way to
unlock the console. Back to -48-33 for the time being.

Up almost three hours with -48-37, and no issues so far. Thanks, Ingo.
I'll let this run for a couple of days and then try out the -50-xx series.

i'm not sure it's related to the lockup - but there is a generic bug in

local_irq_save(flags);

CALL do_tx_done()

spin_unlock_irq(&dev->tx_lock); // [1]

ns83820_tx_timeout(). (local_irq_disable() use in ns83820_tx_timeout()
was probably SMP-unsafe too, but needs a rare race.)
find the patch below - it's also included in the -50-05 -RT tree i just
uploaded. Can you confirm that you dont get the warnings in the -50-05
(and later) -RT kernels?

this does seem to be similar to other reports where the cause of such
latencies was some sort of hardware-level latency. (DMA related delays
or other, bus-arbitration related delays)
another possibility is that something interesting happened on another
CPU while this latency occured - to debug this please enable all-CPUs
tracing:
echo 1 > /proc/sys/kernel/trace_all_cpus
and send me a new trace.

-48-37 still gave the warnings on ns83820_tx_timeout(), but otherwise ran
for a day without any lockups or loss of network or keyboard. No warnings
so far with -50-06. I'll keep you posted.

-50-06 locked up shortly after starting:
dd if=/dev/urandom of=/dev/null bs=8192
No bug warnings on the ns83820, but I did get these messages (last thing
that made it syslog):

Anything to worry about?

Normal use should never be triggering a tx timeout, but it was tested back
when it was written and shouldn't be causing a hang. What sort of setup
is this? You'll probably need a serial console to catch the dieing gasp
of the kernel, as it will likely be enlightening.

FWIW, 50-06 is running clean here with mode 3 & no hardirq threading.
Uptime is about 9 hours.
Would it do any good to try mode 4 & see if tvtime still runs?
Previously, I got the impression that was a dma problem & posted some
of the logs, but I've not noted any fixes for that go by.

sure, any extra testing - even if it finds no problems, is just as
useful. Especially if you have a .config where everything works. That
way we'll know for sure that any regressions are related to PREEMPT_RT.

look at the CPU# column, we have trace entries from both CPU#0 and CPU#1
- and both of them are delayed by 200 usecs! The CPU#0 delay happened in
the idle thread, between preempt_schedule() in __schedule() and
_raw_spin_lock in __schedule(). It's a codepath where there's no
spinning done. The CPU#1 delay happened in the wmResh process, between
__up_mutex()'s entry and the first _raw_spin_lock() it did. This too is
a codepath where no spinning is done. (and even if there was spinning,
the two locks are not the same.)
in other words, since there is no OS-level explanation for the delay,
this can only be an effect of the hardware/system. (Or it could be a bug
in the measurement, but the likelyhood of seeing a 200 usec bump in the
measurement is quite small.)

the second trace seems to be a cross-CPU wakeup bug. It's not completely
clear from the trace what happened - but we measured the latency of a
task (wmcube-3191), where the wakeup happened on CPU#0 and wmcube-3191
was queued to CPU#1 which was idle at that time. The bug is that it
wasnt until timestamp 306us that this actually happened - and CPU#1 was
just idling around in default_idle() for no good reason. CPU#1 should
have run wmcube-3191 at around timestamp 13us.
I've uploaded the -50-07 kernel which will put some more info into the
traces - could you try to repeat the measurement and get similar
latencies? As i guess you already found out that you can always reset
the measurement to get a new set of traces, via:
echo 0 > /proc/sys/kernel/preempt_max_latency
(it's not a problem if you send me multiple latency traces, i'll figure
out which is the most useful one.)

ok, managed to reproduce it on a HT box, and it turned out to be a bug
in the SMT scheduler: the dependent sleeper logic incorrectly delayed
high-prio tasks, causing these latencies. I fixed it in the -50-10
kernel - could you redo your tests with that kernel (or later versions)?

I can report that mode 4 is not at all well here. I turned it on and
changed the extraversion, built it, and when it booted, it got to
this line and hung:
Checking to see if this processor honours the WP bit even in
supervisor mode... OK.
And I had to use the hardware reset to recover & boot to a mode 3
version of 50-06.
That .config is attached.

I can also report that the modules did not get installed, I'd
forgotten to rename the src tree to match the extraversion, so the
final cd my script makes to install the modules failed. I have a new
version building to dbl-check this.

And that also resulted in the hang at the above lines completion.

Hi Ingo,
Latency traces (attached) are looking a little bit better with -50-11.
The CPU consistently seems to idle for ~200us at a time in the traces.
Maximum wakeup latency since boot (over an hour ago) is 310us. With
previous RT kernels, maximums would generally go over 800us.
Should I apply your SMT scheduler latency fix, or is that patch for -mm
only?

these are all the first type of latencies, which seem to be hardware
related. Could you try to boot the UP kernel, do you see these latencies
there too? (if yes then please post those too)

the fix is in current -RT kernels already. As can be seen from the
latency traces you got, the SMT scheduler is not causing latencies
anymore.

On -50-11 UP, the ~200us idle is still showing up in the traces. This
idle time, however, seems to be at random points within the trace. Some
of the traces attached are nearly identical except for where the ~200us
jump happens to fall. Hardware induced latency?

yes, very likely hardware (or system BIOS, e.g. SMM) induced.

Hi Ingo,
I just found this oops from last night on my home audio/midi system
(AthlonXP running -48-37). I was burning a CD at the time, and the scsi
error precedes the oops trace by 46 seconds. The system is still up and
fully functional, BTW.
scsi: unknown opcode 0x01
BUG: Unable to handle kernel NULL pointer dereference at virtual address

Is this something you've already fixed in the -50-xx series? My build of
-50-15 just finished, so I'll reboot and hammer on the cd burner with the
latest, anyway.

Found the bug and it should be fixed in -50-16 and later kernels. I had
debugging code that called into print_IO_APIC() (when you had an scsi
interrupt timeout), but that function was an __init call - so the kernel
called into an already freed code area.

I just tried to build & boot 50-17 in mode=3, no hardirq's and got the
same boot failure as mode 4 for 50-06 gave:
On screen:
Checking to see if this processor honours the WP bit even in
supervisor mode... OK.
and its stuck, needs a hardware reset to recover. The next line
should be the bogomips check/report I believe.

Running -50-17 on the Xeon/HT box, now with the ICH5 USB controller
disabled in BIOS.
The strangely regular ~200us idle jumps for both CPUs went away. Now I'm
seeing one CPU at a time disappear (often completely absent) in the
traces, with a the maximum wakeup generally hitting between 150us and
300us. While compiling a kernel and running vlc (which would skip frames
like mad, even with RR scheduling) I was able to get one trace of 2556us.
There's also BUG warnings for update_out_trace(). I'm not quite sure if
the trace behavior I'm seeing is related to this bug, but judging by the
behavior of vlc, I wouldn't bet on it.
Since the 2556us trace is quite large all the info is posted at:

OK... Running on -50-17 with all RT debug except CONFIG_WAKEUP_TIMING and
CONFIG_LATENCY_TIMING disabled. Max wakeup latency is 59us now, with a
couple erroneous values of 2533412143us. VLC performance (streaming from
a multicast UDP source) was great with one instance of burnP6 running.
Running a second burnP6 along with VLC locks up the box (reproduceable) in
about a minute. Running two or more instances of burnP6 without VLC does
not result in any odd behavior or noticeably impact GUI performance. I
rebuilt with CONFIG_DETECT_SOFTLOCKUP enabled, but couldn't catch a trace.

do you have the NMI watchdog enabled? Find below
serial-logging-earlyprintk-nmi.txt.
Ingo
to set up serial logging:
-------------------------
install a null modem cable (== serial cable) to one of the serial ports
of the server, connect the cable to another box, run a terminal program
on that other box (e.g. "minicom -m" - do Alt-L to switch on logging
after starting it up) and set up the server's kernel to do serial
logging: enable CONFIG_SERIAL_8250_CONSOLE and
CONFIG_SERIAL_CORE_CONSOLE, recompile & reinstall the kernel, add
"console=ttyS0,38400 console=tty0" to your /etc/grub.conf or
/etc/lilo.conf kernel boot line, reboot the server with the new kernel
command line - and configure minicom to run with that speed (Alt-S).
e.g. my /etc/grub.conf has:
title test-2.6 (test-2.6)
root (hd0,0)
kernel /boot/bzImage root=/dev/sda1 console=ttyS0,38400 console=tty0 nmi_watchdog=1 kernel_preempt=1
if everything is set up correctly then you should see kernel messages
showing up in the minicom session when you boot up.
When the messages do not show up then typical errors are mismatch
between the serial port (or speed) and the device names used - if it's
COM2 then use ttyS1, and dont forget to set up the serial speed option
of minicom, etc. You can test the serial connection by doing:
echo x > /dev/ttyS0
and that should show up in the minicom session on the other box.
to set up early-printk:
-----------------------
occasionally lockups/crashes happen so early in the bootup that nothing
makes it even to the serial log. In that case the 'earlyprintk' feature
is most useful. It is default-enabled on all 2.6 kernels, you only need
to add one more boot parameter to activate it over the serial console:
earlyprintk=serial,ttyS0,38400
to set up the NMI watchdog:
---------------------------
add nmi_watchdog=1 to your boot parameters and reboot - that should be
all to get it active. If all CPU's NMI count increases in
/proc/interrupts then it's working fine. If the counts do not increase
(or only one CPU increases it) then try nmi_watchdog=2 - this is another
type of NMI that might work better. (Very rarely there are boxes that
dont have reliable NMI counts with 1 and 2 either - but i dont think
your box is one of those.)
once the NMI watchdog is up and running it should catch all hard lockups
and print backtraces to the serial console - even if you are within X
while the lockup happens. You can test hard lockups by running the
attached 'lockupcli' userspace code as root - it turns off interrupts
and goes into an infinite loop => instant lockup. The NMI watchdog
should notice this condition after a couple of seconds and should abort
the task, printing a kernel trace as well. Your box should be back in
working order after that point.
now for the real lockup your box wont be 'fixed' by the NMI watchdog, it
will likely stay locked up, but you should get messages on the serial
console, giving us an idea where the kernel locked up and why. (Very
rarely it happens that not even the NMI watchdog prints anything for a
hard lockup - this is often the sign of hardware problems.)

I had a serial console up, but not NMI watchdog until now. Here's some
NMI watchdog traces from both -50-17 and -50-18:

all of these traces seem to have lockupcli involved - is that correct?
lockupcli is just a userspace test-app to artificially trigger a
hard-lockup (it disables interrupts and goes into an infinite loop). So
the NMI watchdog triggering on lockupcli would be normal and expected.
So once this works, it would be nice to reproduce whatever hard lockup
you are seeing and see whether the NMI watchdog produces any output to
the serial log. (if such log is supposed to be included in your dmesg
then it somehow got intermixed with lockupcli logs)

ok, could you try the patch below, ontop of whatever tree hung for you?

Add "memory" clobbers to the x86 inline asm of strncmp and friends
They don't actually clobber memory, but gcc doesn't even know they
_read_ memory, so can apparently re-order memory accesses around them.
Which obviously does the wrong thing if the memory access happens to
change the memory that the compare function is accessing..
Verified to fix a strange boot problem by Jens Axboe.

Gahh, and I just built -18 but amanda is running so can't reboot
anyway. This is my night to do a graveyard at the tv transmitter so
it'll be the middle of the day Saturday before I get one eye open
simultainiously again. -19 wasn't there 3 or 4 hours ago.
Thanks, I report back when I have done it.

It seems the transmitter only needed a goodnight kiss, so I came back
& built it. So far running good, 5 minute uptime, looks good. More
reports if I find any gotcha's :) Seemed to boot marginally faster
too, but no stopwatch timeings were done.

great. To make sure, these earlier boot failures are gone:

Yes. Same mode 3, no hardirq's config. I have not tried mode=4.
Here thats been a lockup every time for recent versions. I just
checked the log, pretty quiet, nothing out of line.

Now I've tried -22 in mode=4 and its the same hard lockup after this
line is printed to the screen:
"Checking to see if this processor honours the WP bit even in the
supervisor mode... OK"
reset button to recover. -22 in mode=3, no hardirq's now building
while running -19.
-22, mode=3 no hardirq's is running, but it took kmail a couple of
minutes to fully init its screen, with a spamd child eating 99% of
the cpu. The logs are silent after "loading the r200 code" from
startx. But, it seems to be ok now. More data when available.

I still haven't been able to get any NMI watchdog traces with the lockups
induced by VLC and burnP6. Early printk is enabled on the serial console.
I have noticed, however, that scheduling performance slowly degrades
during the ~1 minute before locking up. Once I was able to get a delayed
SysRq response (~30s) from the serial console after the X console became
unresponsive. Is this possibly a scheduler starvation issue that affects
everything, including the NMI watchdog? Any more suggestions for catching
a trace?

In the FWIW category, I booted 50-23 about an hour & a half ago, same
mode 3, no hardirq's, everything seems to be working fine except for
kmails total lack of threading causeing composer hangs while a mail
fetch/spamassassin run is in progress. But thats not anything new to
this patchset, its an equal opportunity annoyer.

hm. Nothing should starve the NMI watchdog. Only a nasty, complete
kernel crash or a hardware failure can lock up the box in a way that not
even the NMI watchdog can get some message out to the console. Just in
case, could you try the latest patch (-50-24 or later), there were a
couple of bugs fixed.

does the patch below make the kmail starvation go away?

I put in the comment and its building now. I rather doubt its going
to make a huge diff though as its probably the single most repeated
bitch on the kmail lists, and has been for a long, very long as in
years, time. From hints dropped here and there, it might finally be
fixed with kde-3.5. But we'll give this a shot nontheless. I'll add
more after I reboot to test.
Now rebooted.
I don't think its made a noticable difference, I'm still getting the
hangs of up to 30 seconds but I'll let it run the rest of the
afternoon so I get a better feel for it. It doesn't often miss a
keystroke, they will eventually be echoed back to the screen.

another symptom (don't know if it's actually related) is that if I
try to switch to a virtual consol (ctl-alt-chift-F[1..6] the screen
won't change out of graphics mode - it goes black like it's trying
to switch but comes back with the graphical screen which isn't responsive
and hitting alt-F7 restores it to operation. I just rebooted to a kernel
that doesn't have the RT-preempt patch but uses the same .config and
everything for switching between X and virtual terminals works just fine.

ah, ok - so kmail behaves similarly on vanilla kernels too? I thought
this might be some -RT-specific degradation.

If you have PREEMPT_RT enabled, it looks like interrupts are hard
disabled then there is a schedule_timeout() requested. You could try
turning off power management and see if you still have problems.

Well, putting apm=off in the kernel command line did the trick. I am
using a desktop system so apm really isn't needed. Time to change my
standard config file..... Thanks.

Its working ok here, but not with those keystrokes. I just did it
several times. Its ctl+alt+Fn here, and always has been.
What I did see on VT#1, where the boinc stuff was being spit out
before I logged in and did a startx, is that I have less then a
screenfull of history available, and unlike previous kernels, I'm
getting a very verbose running trail, almost like an strace output,
of all the kde/kmail activities going on being output to VT#1. VT#2
seems normal and I was able to log into it just fine before hitting
ctl+alt+F7 to come back to X. Weird to say the least.
But this brings up the question re how do I enlarge the scrollback
memory of an init-run-level=3 VT?

As I just posted in another thread, with this boot I am now getting a
huge amount of almost strace like detail being output to VT1 from
kde's/kmails activities. VT1 being the console I did the startx
from. Could this be related to commenting out that line in sched.c?
Sorta new subject next.
Getting all that detail being output to VT1, is there any way I can
enlarge the VT's scrollback memory buffer? It's only about 2kb,
maybe less, less than 2 full screens full. I'm used to haveing about
a 10 meg scrollback buffer available for traceing purposes in an x
console. I'd appreciate the same length of scrollback for the VT's.

Did it solve everything , including the virtual terminal switching, and
the scheduling with irqs disabled ?

OK. Running on -50-25 now. The burnP6 starvation doesn't seem to affect
the whole system, but comes close enough to require the reset button every
time. I usually, but not always, lose network, X, the keyboard, mouse,
and serial console. I'm still unable to get any sort of a trace from
these lockups, since it's looking more like a bunch of processes starving
than a kernel crash or a full lockup.
Once, with VLC (viewing a 5mbit/s mcast/udp stream) and two burnP6
instances running, I was able to fire up top on the serial console and
found out that the IRQ thread for the ns83820 nic was using 99% of one
CPU.
Once, two burnP6 instances made the system unresponsive without running
VLC. Everything froze as soon as I fired the second one up. This may be
a good one to try to reproduce on an HT machine, since it doesn't require
VLC and a multicast video stream to make the system unresponsive.
Once, with a normal desktop load and a yum update, this came across on the
serial console:

Although turning off apm works, this is a fix to the symptom and not a
cure. Has someone already taken a look at this code? Since
apm_bios_call_simple calls local_save_flags and afterwards
raw_lock_irq_restore is then called. Shouldn't that have been
raw_local_save_flags?
That apm_bios_call_simple_asm also looks pretty scary! I haven't yet
figured out how APM_FUNC_VERSION becomes a normal function.

aha! that's an important clue. It seems you've got a screaming interrupt
or some other loop in ns83820 irq handling. Could you do this:
chrt -o 0 -p `pidof 'IRQ 18'`
(assuming your ns83820 device is still on IRQ18) To check the command
was effective, enter the following command:
chrt -o -p `pidof 'IRQ 18'`
and you should see output like:
pid 748's current scheduling policy: SCHED_OTHER
pid 748's current scheduling priority: 0
i.e. the thread is not SCHED_FIFO anymore.
this will not fix the ns83820 problem for you, but will make it more
debuggable - you will still probably lose networking, but keyboard and
the local console should work fine. You should see a 99% CPU-time
looping ns83820 IRQ thread when the condition triggers. To debug the
condition further, could you do something like:
vmstat 1
what kind of interrupt rate ('in' field) does it report? If it's very
high then it's a screaming interrupt, if it's low then the IRQ thread is
looping for some other reason. (but both would be bugs of the -RT
kernel.)
also, could you try to get a trace of what the IRQ thread is doing. I've
attached trace-it.c, just run it as root (on a LATENCY_TRACING-enabled
-RT kernel) to get a finegrained trace of what's going on in the system.
Whenever the thread-spinning occurs, just run this utility:
trace-it > trace.txt
and you should get a couple of milliseconds worth of system activity.
The trace output should look like a really long latency-trace. (The
latency traces usually compress really well with bzip2 -9, so you can
attach it to public replies too, if compressed - that way others can
have a look too.)

on SMP this could occur if the TSCs of different CPUs are too apart from
each other. I'll probably put an automatic check for this into the
/proc/latency_trace code.

no idea. In gnome-terminal if you edit the current profile there's a
scrollback item with # of lines of scrollback you can save.

The question is where the call to schedule happened. If it was between
the local_save_flags and irq_restore, then I believe the interrupts are
off and the schedule can take place. But if it was afterwards, then this
is probably the fix since the irqrestore probably didn't restore it.
I guess we need to wait for Chuck to answer this.

i've also uploaded -50-27 in which i've improved the irq-flags debugging
code. They are activated if CONFIG_DEBUG_PREEMPT is enabled, and can
come in two variants of kernel messages:
BUG: bad raw irq-flag value 80000000, test/3810!
BUG: bad soft irq-flag value 00000202, test/3810!
so we should now be able to detect mismatches of irq flags right where
they occur.

i just found and fixed a bug in -RT that could cause screaming
interrupts. Could you try the -50-28 (or any later) kernel, does it fix
the problem?

Hi Ingo,
check_raw_flags needs to be exported. The attached one-line patch is

It's working fine now - switching back and forth between graphical mode
and text console (which works with or with out the shift key B-) and no
more flooding of BUG: scheduling with irqsw disabled in dmesg. I did
notice that 50-24 kernal was hard locked up when I came in this morning.
SysRq-B would not reboot it and pinging from another machine said it
was down. I went ahead and booted up another kernel and saw the message
about 50-30 so I built that and that is what I am running on now. I really
like using it because X works much better at rendering the screen and
screen animations are really smooth. (this is on a 2GHz P4 with 1Gb RAM)

Ack!! I didn't have that enabled so I am rebuilding again. One thing I've
noticed is that sox seems to be hanging when it is trying to play a .wav
file (for system beeps) and there aren't any error messages about what
might be going on.

More info - sox is locked up so tight that no kill can stop it. I'm not

there doesnt seem to be too much of an interrupt related problem:

you are getting a timer interrupt (IRQ 0) every 1000 usecs, as expected.
i'd suggest to capture trace-it traces only during a clearly identified
anomalous event such as an interrupt storm. For latency analysis
purposes the default latency traces are better.

was this on a -29 or later kernel? (-29 had a couple of latency.c fixes)

this is a quick hack. The timer code is fully preemptible, but for
debugging one wants to have a working printk from hardirq contexts too.
I.e. the mod_timer()/del_timer() would print warnings on PREEMPT_RT.
We'll need some other approach to solve this cleanly.

x86-64 needs the attached patch to compile.
Some drivers also fail to compile because of
SPIN_LOCK_UNLOCKED changes, e.g. softdog and
four files under net/atm. Just take the x86-64 UP
config from FC3's latest errata kernel.
I haven't booted it yet.
A question, though: why do you comment out the
DMPS timer in drivers/char/vt.c?
Does it cause any problems? I applied the -RT tree
after the multiconsole patch and I had to modify
those four chunks manually.
Best regards,
Zoltán Böszörményi

the patch in essence generalizes the ARM IRQ features and merges them
into the generic IRQ code - with minimal impact to the current ARM way
of doing interrupts. The long-term end-result should be more
architectures using the ARM IRQ handling methods such as irqchip.

Well, making it is one thing, getting Russell to accept it is a whole
other issue.. Are you still willing to make the RT patch a sandbox for
this?

Thomas and me already did that - i think Thomas could send a patch for

I can make it work, but Ingo isn't accepting non-generic IRQ arches .. So
it's pretty much on hold until someone bring ARM into the generic IRQ
world.

We have a working version for ARM based on a primary patch which
integrates ARM into the generic irq handling

What arches are likely to work in the near future?
I've seen that "Kconfig.RT" is sourced for i386, x86_64, ppc,
and mips, but not for arm.
arm is one of the platforms we are interested in, any chances?
