Hi Paul,
I've had this hang a couple of times now, so I figured it isn't an
isolated event. I am getting kernels occassionally hanging with the
following output occurring:
[ 62.812011] INFO: rcu_sched_state detected stall on CPU 8 (t=15000 jiffies)
[ 242.936009] INFO: rcu_sched_state detected stall on CPU 8 (t=60031 jiffies)
And that just goes on until I reboot the machine. e.g. from a test
run on a 2p VM that I didn't check on over the weekend:

[222148.428010] INFO: rcu_sched_state detected stall on CPU 0 (t=55176750 jiffies)
I've seen it on 2p and now a 16p test VM. This one occurred
during boot of the 16p VM:
[ 2.600499] kjournald starting. Commit interval 5 seconds
[ 2.600878] EXT3-fs (sda1): mounted filesystem with ordered data mode
[ 2.600995] VFS: Mounted root (ext3 filesystem) readonly on device 8:1.
[ 2.612351] Freeing unused kernel memory: 2824k freed
INIT: version 2.88 booting
Using makefile-style concurrent boot in runlevel S.

[ 242.936009] INFO: rcu_sched_state detected stall on CPU 8 (t=60031 jiffies)
While the console still echos characters, the boot process is
not making progress.
I've had this happen under heavy CPU and IO load, sometimes hours
after boot e.g. one was mid-way through a 4th run of xfstests which
takes about 80mins to do a complete run. There doesn't appear to be
any pattern to when it occurs and I cannot reproduce it on command,
so tracking it down might be difficult.
Cheers,
Dave.

This might be a false alarm - I've just diagnosed(*) that a kernel
thread was stuck in a hard loop therefore not giving up the CPU.
Perhaps this is error message could be more informative?
The detector is acting like the hung task detector, except it's
working on kernel code stuck in a loop burning CPU, so maybe dumping
a stack trace of the spinning CPU (i.e. similar to sysrq-l output)
might be a useful addition to tracking down such stalls?
Cheers,
Dave.
(*) luckily the kernel was still responding to the kvm sendkey
command so I could get at sysrq dumps to the console...

Ah, that is indeed one of the conditions that RCU CPU stall warnings
can catch.

Strange. There is a trigger_all_cpu_backtrace() call that is supposed
to dump all CPUs' stacks. It has been working in the past, but you are
the second person in a couple of weeks to report that it isn't doing
its job. (Though the other one was running the -rt tree.)
Wait a minute... Here is the definition:
#ifdef arch_trigger_all_cpu_backtrace
static inline bool trigger_all_cpu_backtrace(void)
{
arch_trigger_all_cpu_backtrace();
return true;
}
#else
static inline bool trigger_all_cpu_backtrace(void)
{
return false;
}
#endif
Passing a lower-case symbol to #ifdef is a bit of a red flag. Where
is it defined?
o arch/sparc/include/asm/irq_64.h:
#define arch_trigger_all_cpu_backtrace arch_trigger_all_cpu_backtrace
o arch/sparc/kernel/process_64.c:
void arch_trigger_all_cpu_backtrace(void)
{
...
}
o arch/x86/include/asm/nmi.h:
#define arch_trigger_all_cpu_backtrace arch_trigger_all_cpu_backtrace
o arch/x86/kernel/apic/hw_nmi.c:
void arch_trigger_all_cpu_backtrace(void)
{
...
}
So I am guessing that you are running some architecture other than
x86 or SPARC. And the implementation is a bit hostile on other
architectures. So I suggest adding a dump_stack() before the
"return false" in trigger_all_cpu_backtrace(), as in the patch
shown below.
But this is still strange. I -know- I have seen stack dumps for
all CPUs when running on Power... But the code has not changed
for quite some time.
Nevertheless, could you please try out the patch below? It should
get you at least the stack dump for the current CPU, which in your
case was the offending CPU.
Thanx, Paul

Ok, so it is supposed to be dumping the stack. Good.

I'm running on x86_64 (inside a KVM VM) so it should be present.
Hmmm - I note that sysrq-l has a fallback implementation that uses
smp_call_function() should trigger_all_cpu_backtrace() return false.
I'd bet that's why sysrq-l is working and the rcu stall detection
isn't. i.e arch_trigger_all_cpu_backtrace() is either broken or for
some reason not compiled in. I can't tell why - I get lost in all
the different ways that arch specific code is inlined by
preprocessor magic...

I'll give it a go, though perhaps using the same fallback as sysrq-l
might be a better idea?

Indeed it should! Is NMI delivery busted or something?
In addition, how about putting a compiler error into
trigger_all_cpu_backtrace() and verifying that your build fails? Just in
case and all that.

If your architecture really does believe that trigger_all_cpu_backtrace()
is available, my patch will have no effect. Substituting dump_stack()
for trigger_all_cpu_backtrace() would be helpful.
Just out of curiosity, what are you thinking of doing in the code to
figure out that trigger_all_cpu_backtrace() didn't work and that it
was time to fall back on sysrq-l-style processing?
Thanx, Paul

Not that I know of.

Easier just to check the return value:
#ifdef arch_trigger_all_cpu_backtrace
static inline bool trigger_all_cpu_backtrace(void)
{
arch_trigger_all_cpu_backtrace();
return true;
}
#else
static inline bool trigger_all_cpu_backtrace(void)
{
return false;
}
#endif

- trigger_all_cpu_backtrace();
+ if (!trigger_all_cpu_backtrace()) {
+ pr_err("trigger_all_cpu_backtrace returned false!");
And I see:
[ 90.808037] INFO: rcu_sched_state detected stall on CPU 8 (t=15000 jiffies)
[ 90.808037] trigger_all_cpu_backtrace returned false
Which indicates that arch_trigger_all_cpu_backtrace is indeed not
defined, and that sysrq-l is using the fallback.
My .config is below if you want to look into it further.
Cheers,
Dave.

if (!trigger_all_cpu_backtrace()) {
pr_err("Falling back to dump_stack()");
dump_stack();

My ability to do so is quite limited, but you do have
CONFIG_X86_LOCAL_APIC=y. I took a quick look but don't immediately
see why you would not be getting the NMI variant.

It would appear to be because include/linux/nmi.h does not do
#include <asm/nmi.h> where arch_trigger_all_cpu_backtrace is
defined.
I think this is the case from looking at the build deps for
rcutree.h: I see include/linux/nmi.h but no asm/nmi.h. It appears
that asm/nmi.h is only included if this config ifdef is true:
#if defined(ARCH_HAS_NMI_WATCHDOG) || defined(CONFIG_HARDLOCKUP_DETECTOR)
#include <asm/nmi.h>
And my .config has:
$ grep CONFIG_HARDLOCKUP_DETECTOR .config
# CONFIG_HARDLOCKUP_DETECTOR is not set
$
And ARCH_HAS_NMI_WATCHDOG is only defined for these archs:
$ grep ARCH_HAS_NMI_WATCHDOG -r arch
arch/blackfin/include/asm/irq.h:# define ARCH_HAS_NMI_WATCHDOG
arch/mn10300/include/asm/reset-regs.h:#define ARCH_HAS_NMI_WATCHDOG /* See include/linux/nmi.h */
arch/sparc/include/asm/irq_64.h:#define ARCH_HAS_NMI_WATCHDOG
$
So unless you configure the CONFIG_HARDLOCKUP_DETECTOR into a
kernel, trigger_all_cpu_backtrace() will simply fail.
And i can't just convert this to always include asm/nmi.h, because:
$ find arch -name nmi.h
arch/blackfin/include/asm/nmi.h
arch/mips/include/asm/sn/nmi.h
arch/mn10300/include/asm/nmi.h
arch/s390/include/asm/nmi.h
arch/sparc/include/asm/nmi.h
arch/x86/include/asm/nmi.h
$
Only a few platforms actually define asm/nmi.h. The whole platform
specific trigger_all_cpu_backtrace() stuff is just broken - it's not
just platform specific, it's platform and config specific, without
having any indication that it is config specific....
Arch specific code is supposed to have a generic implementation for
platfoms that don't implement it. It's pretty clear from the
sysrq-l code that a generic implementation is possible, so I'm
wondering why trigger_all_cpu_backtrace doesn't own that generic
fallback code.....
Cheers,
Dave.

This does seem a bit sub-optimal to me as well. :-/
In the meantime, I am calling dump_stack() if trigger_all_cpu_backtrace()
returns false.
For whatever it is worth, one issue with using something like
smp_call_function() in my particular case is that irqs are disabled.
Thanx, Paul

*sigh*. It seems as though I broke this with commit
4a7863cc2eb5f9804f1c4e9156619a801cd7f14f when I tried to cleanup
the namespace a little bit.
I am going to have to find a file to move the #define arch_trigger_* stuff
to. Forcing it to include the asm/nmi.h file with the LOCKUP_DETECTOR
config option disabled screws up all the touch_nmi_watchdog logic.
Maybe I can stick it in an asm/irq.h header file or something that gets
included from a top level linux/*.h file. Dunno.
Sorry about that.
Cheers,
Don

Hi Dave,
Does this patch solve your problem?
