This lockup is pretty reliably reproducible (but only under Xen). I've
seen this happen under multiple hardware configurations and multiple
different configs.
Basically run 'perf top', wait around 30 seconds and see if you still
have keyboard interactivity. If I tell perf to exit (via 'q') before
it has a chance to hang completely, I get this in dmesg:

perf: Remove the nmi parameter from the swevent and overflow interface
The nmi parameter indicated if we could do wakeups from the current
context, if not, we would set some state and self-IPI and let the
resulting interrupt do the wakeup.
For the various event classes:
- hardware: nmi=0; PMI is in fact an NMI or we run irq_work_run from
the PMI-tail (ARM etc.)
- tracepoint: nmi=0; since tracepoint could be from NMI context.
- software: nmi=[0,1]; some, like the schedule thing cannot
perform wakeups, and hence need 0.
As one can see, there is very little nmi=1 usage, and the down-side of
not using it is that on some platforms some software events can have a
jiffy delay in wakeup (when arch_irq_work_raise isn't implemented).
The up-side however is that we can remove the nmi parameter and save a
bunch of conditionals in fast paths.

Hm, during bootup what does perf say about the CPU availability? Is
it that it can only do perf via NMI's?

We used to pass down if the event came from NMI context or not in order
to avoid doing certain things that were not NMI-safe, like wakeups.
That patch changed the code so that it always assumed the worst case
(NMI) and thus avoids doing such things.
All non-NMI-safe operations are pushed out to IRQ context through
kernel/irq_work.c. If there's no particular platform support for that,
it falls back to doing that work from the timer tick.
Now that all _should_ just work but clearly there's a problem there.
I haven't tried making sense of the traces yet..

This looks like its waiting for an IPI to complete..
There's no actual BUGS or WARNs in the output, just the soft lockup
thing saying things are taking a bit of time (clearly 15s waiting for an
IPI isn't quite normal).
I've no idea why this wouldn't work on Xen, nor do the trace have any
Xen specific muck in them.

Hmm, Ben you tried some kdb debugging using Xen and ran in some IPI issues
didn't you? Do you remember what was the problem?

Hmm. I just noticed the 'perf test' command in 3.2.5. It seems to be a
much more reliable (or at least faster) way to trigger the soft
lockups. Testing this on my work laptop for now (I can test on
something else if needed, but I figured this would do fine).

<hang for about a minute before finishing>
It hangs after test 3 and then soft lockup messages start spewing out.
The interesting bit about this is that it does eventually recover -- I
presume this is because the test is short and there's just really high
latency on the responses it's waiting for.
Here's a kernel log I just got for a full 'perf test -v 3' run under xen:

It actually gets even more interesting. Once I did 'perf test' under
Xen, and I waited for it to finish, perf suddenly works fine. I can
re-run 'perf test -v 3' with no hangs, and can now run 'perf top' with
no issue. Bizarre.

Heck, I keep wishing people use perf test more often to figure out bugs
sooner, but this side effect was surprising! ;-)

Re-send, with patch pasted in-line, rather than attached...
Hmm - sorry I neglected this - it got filtered into my LKML folder,
which I usually ignore, unless I'm looking for something.
I'll have to adjust that filter for when I'm in the To: line.
I've attached a work-in-progress patch, that allows for kdb to work
with the hvc console.
It assigns some IPI functions that may be applicable here...
That said - I'm not convinced it "rounds up" the cpus
properly...though I haven't been able to prove otherwise. It seems to
work generally...

(I just set up Mutt as my mailer because GMail is stomping long lines on
me, and I don't like it one bit. I apologize if this mail isn't sent
correctly; I'm still tweaking my muttrc to work for LKML.)
So your patch does something interesting. Instead of getting a lengthy
hang with 'perf test', I now get a NULL pointer BUG instantly:

It seems to me that there are two options for fixing this, but I'm
probably lacking the necessary context (or experience with Xen). Either:
- The patch provided by Ben needs to have additional work to specially
handle IRQ_WORK_VECTOR, since it seems to be a special case where
there's no event channel attached for it. Perhaps adding an event
channel for this is the fix? Seems high-overhead, but I lack a good
understanding of how interrupts are handled in Xen.
or
- Perf needs to be "enlightened" about Xen and avoid sending an IPI in
the first place.
Is this a fair assessment?

So that's a self-IPI, is Xen failing to implement this?

Uhm, no. If anything Xen should simply not implement
arch_irq_work_raise(). The callbacks are then ran from the timer
interrupt.

Yes.
Ben's patch implements it, but it explodes (NULL pointer dereference)
when it can't find an event channel for IRQ_WORK_VECTOR.

Sorry, wild guess. I'm a kernel newbie. :)

It does have self-IPIs.

Looks like that wouldn't be too difficult - meaning implement a similar
form of IRQ_WORKER that would call
inc_irq_stat(apic_irq_work_irqs);
irq_work_run();
.. along with the rest of the stuff from Ben's patch. Let me see if I can
prep a patch.

Actually there is an existing self-IPI framework so that any of the smp_call_*
end up IPI-ing other CPUs and that seems to work OK.
274: 700 0 0 0 0 0 xen-percpu-ipi callfunc0
276: 15184 0 0 0 0 0 xen-percpu-ipi callfuncsingle0

CAL: 15886 8981 5724 19977 22657 11114 Function call interrupts
So even without Ben's patch it should have worked. I am not actually sure
why it decided to just sit there. Looking at it, the IPI on both native
and xen would end up calling: generic_smp_call_function_single_interrupt()
from their respective single-IPI interrupt handlers.
Jeremy, was there any difficulities when IPI oneself?
