This patch for SVN trunk fixes most of the current bugs around hardware
timer takeover and release from/to Linux. Tested and found working here
(including SMP):
- 2.6.22, APIC, highres=off, nohz=off
- 2.6.22, APIC, highres=on, nohz=on
- 2.6.20, APIC
Tests to be done:
- 2.6.22, PIT (currently building...)
- 2.6.20, PIT
Things became quite complex in i386/hal.c now. Some of this complexity
might be avoidable if RTHAL_APIC_TIMER_VECTOR equalled
LOCAL_TIMER_VECTOR. What's the reason for this? Is it something related
to pre-highres times of Linux (ie. 2.6.20 and earlier)? Can we overcome
it, at least for recent kernels?
So, while this patch may work correctly, my feeling is it needs yet
another round of polishing, also looking for now possibly outdated comments.

Hi Jan,
[taking this on the list after several mails with Philippe...]
Le jeudi 11 octobre 2007 à 22:47 +0200, Jan Kiszka a écrit :
> This patch for SVN trunk fixes most of the current bugs around hardware

[...]
I have a problem with the timer on my MacBook Pro (Core2Duo, used in
_32_ bit mode)(*): when Xenomai takes over the timer (at 'modprobe
xeno_native' time), the Linux timer stops.
Looking into /proc/xenomai/irq shows that Xenomai does receive the
hardware interrupts, and /proc/interrupts shows that they are no longer
forwarded to Linux. Before loading xeno_native, everything is ok.
Linux userspace continues to somewhat work: I can issue commands, and
depending on the syscalls they made I suppose (no, strace doesn't work),
sometimes they end correctly sometimes they hang (and I cannot interrupt
them by ^C or other signals.).
I tried several .config variations, without any change in behaviour: my
current test config has SMP, NO_HZ, APIC, PREEMPT, HIRES all disabled).
This happens with a 2.6.22.9 kernel, adeos-ipipe-2.6.22-i386-1.10-07,
xenomai svn HEAD (rev 3050), with or without your current patch. It is
quite possible that this is not a new problem, since I have this laptop
since a few weeks only and I never ran Xenomai on it.
I'll happily provide any further information or test results if you
need.
Thanks,
Stelian.
(*) yeah, I know I could install a x86_64 distribution but I had some
terrible experiences in the past - mainly due to the usage of some
proprietary bricks like flash, java etc. I know some of those have been
resolved today, and one of these days I should try once more, but now it
is not a good time for this.

To close this topic: Also the tests with APIC switched off were
successfully completed yesterday. So the logic should be fine now, ...

Hmm, that's not too different from my own test setup.

/proc/xenomai/timerstat/master may provide further hints about the state
of the host timer (please keep my patch applied for this). Also, you
could take an I-pipe trace around the timer takeover and the following
few milliseconds, using the new trigger feature:
echo rthal_timer_request > /proc/ipipe/trace/trigger
BTW, does the latency test of Xenomai work?

The way it works resembles the way Linux works around an issue raised by
broken APIC hardware, whose timer bluntly stalls when entering C3. For
this reason, Linux keeps the i8253 as the master tick device, and
broadcasts the APIC-based local timer vector on all CPUs from the tick
handler. Not doing so would stop the timekeeping when entering a sleep
mode (this what the tick-broadcast mode is about with generic clock
events support in recent kernels).
This said, we do rely on the APIC timer to program the delivery of
RTHAL_APIC_TIMER interrupts in oneshot mode, so the above work around
does not help us a lot when it comes to C3 on broken hardware anyway.
(Not to speak of the TSC which may stop when entering C2 or get
corrupted in C3 in many cases too...)
Another issue to take into account is the cost of timekeeping through a
Xenomai host timer and explicit propagation of a faked LOCAL_TIMER
interrupt via the I-pipe, from the real-time domain to the root domain
(what we would have to do in order to recycle the local timer vector),
compared to the cost of letting the Linux timekeeping stuff live its own
life in parallel, without any intervention from the Xenomai side.
To sum up, I'd say that we could work the way we are already running in
PIT mode, and relay host ticks to Linux, freeing the local timer
interrupt for our own use. But this may also be more expensive for the
real-time side. We are lacking some benchmarks here, but this could be
tested quite easily (we would need to disable IRQ0 when the host ticking
service is handed over to Xenomai though).

Sorry, I can't follow your argumentation at this point: For 2.6.22, we
are now already relaying the Linux ticks, for _all_ configurations. In
the rare case that Linux decides to use the PIT (e.g. because the NMI
watchdog is active), the APIC does not work for us right now anyway.
So, if we are already relaying the host timer, my question remains why
we need to use a different APIC timer vector in this case. If we may
decide to enhance I-pipe in a way that it redirect Linux to the PIT
clockevent driver in case we want to use the APIC, than this is a
different discussion, of course.

Yeah, good question: What is cheaper latency-wise, timer separation in
hardware or stacking in software? Performance-wise I think the
switch-back to the PIT is not optimal for the overall system.

> BTW, does the latency test of Xenomai work?
No. It hangs after "warming up". I'm able to interrupt with ^C and then
it prints a single line showing a max latency of 208983.492 ms (same value
on several invocations).

/frozen holds the result. Also, a bit more post_trace_points may help to

Ah, then we may fail to program the APIC appropriately. That would need
a closer look if you want to dig into this. /me is going to be
distracted from this for now.

I will happily see this legacy code improved if we can do this without
adding too much complexity. The recent surge of bugs in this area pleads
for both sides.
So, yes, we do relay ticks when generic clock events are available, this
was a recent change of mine when porting over this infrastructure for
2.6.22. But as you know, this won't work for anything earlier, until we
move the whole damn thing under host tick emulation for everyone. And to
get to that point, we will first need to recycle the local timer for
every purpose, when the APIC is enabled, as you initially suggested.
Making this change is a no-brainer implementation-wise, I'm just
-reasonably- worried about the performance cost imposed on the real-time
side. Hence the open question I raised.

Except that in such a case, we don't need any non-preemptible real-time
code to be executed in order to schedule the interrupt for processing by
the kernel. Faking the interrupt through propagation to each CPU would
clearly add more pressure on the nklock too, even if we try hard to
stagger the per-CPU clocks to avoid obvious contentions. IOW, moving
everything on top of Xenomai's core timer would cause Xenomai to spend
some time in a non-preemptible way in order to relay the tick to Linux
for each CPU, and that could have an impact latency-wise, maybe.
We need benchmark figures to sort out this issue, at least to measure
the cost induced by host tick emulation on top of the Xenomai domain,
including in SMP mode.

I'm not sure how much time I have to investigate this, but yes, I can take a
look if you tell me what I should look for.

Ah, CONFIG_M486. Try to pick a less generic CPU type, maybe TSC-less
support got broken recently.

It looks like we are still using the TSC emulation over the 8254; I
don't ever recall if it's supposed to work actually. Now that the
remaining known issues have been fixed by Jan's latest patch, could you
switch your CPU config to CORE2, instead of 486? Maybe we'll get lucky.

...HPET_TIMER must be off as well. Otherwise, Linux may actually pick up
the HPET which block the PIT for Xenomai usage.
Philippe, can we merge my patch to detect this conflict?

Right. Disabling CONFIG_HPET makes Xenomai work for me on this laptop.
Hurray!
I still have a strange problem though: after loading xeno_nucleus and
before loading xeno_native, the keyboard reacts strangely: each key
press results in at least 6 (and up to 20) letters on the terminal.
Before loading the nucleus and after the skin is loaded everything is
ok. And even while the keyboard reacts strangely, I can log in over ssh
and the systems seems to be fine.
What should I do next ? Do you want to try looking into the keyboard
issue, or should I rather enable the UP_APIC ? Or even go crazy and
activate SMP again ?
Stelian.

Would have been too easy:
# modprobe xeno_native
Xenomai: native skin init failed, code -19.
This is with all relevant options on (HPET, HIRES, SMP, NO_HZ).
I guess I'll have to take one step at a time.

The I-pipe likely told Xenomai that the LAPIC was unusable, because it
has been put in dummy state by the clock event layer. Must be something
silly going on at I-pipe level. Please switch HPET off just for kicks.

No, it doesn't change a thing.
What does change something however is CONFIG_X86_UP_IOAPIC. Without it
(UP or UP+APIC), latency works (albeit with higher latencies - up to 30
us - than with 2.6.20+xeno-2.3.4 - where I saw latencies up to 20-25
_in_SMP_mode_). With IOAPIC I get code 19.

FYI, I am no longer able to reproduce this keyboard problem today. Could
be because or a temporary USB problem, or because I did a cold boot this
morning... Or it could be anything else...

Those 5 us are likely due to the programming overhead of the PIT (in
contrast to the fast IO-APIC in LAPIC/SMP setups).

Where do you get ENODEV? On nucleus startup? Please provide
/proc/timer_list output of the working and non-working setups.

PS: For unknown reasons your mails don't make it to my web.de address,
only to the list. Do you get any error messages?

It turns out that I had the Linux NMI watchdog enabled (nmi_watchdog=1
on the command line) and this was causing the -ENODEV problems. Once
removed, I'm able to boot and successfully run all configurations: UP,
UP + APIC, UP + APIC + IO_APIC, SMP. And the latencies are back to normal.
Maybe we should detect that the NMI watchdog is enabled and issue a
warning message, this would save others a few hours and many kernel
builds...
This is with your timer cleanup patch, of course.

I did get one saying:
<jan.kiszka@domain.hid>: host mx-ha02.web.de[217.72.192.188] refused to talk to me:
554 Transaction failed. For explanation visit
http://freemail.web.de/reject/?ip=88.191.70.230
I didn't investigate yet what's happenning.

The clock event layer turns off the APIC timer when the NMI watchdog is
set to use the IO-APIC. Unfortunately, using nmi_watchdog=2 may just not
work at all on broken hardware with recent kernels (like the one I have
just in front of me...).

There is work in progress on the NMI issue, but this message will likely
appear until we've fixed this properly.

NMI is still broken for >= 2.6.22, known issue :-/. The problem is that
Linux falls back to the PIT, leaving our beloved APIC in disabled state
which makes Xenomai fail when asking for it. $Someone has to look into
the reason why we cannot take over the APIC in that scenario...

Your IP is probably associated to some DSL access, and a lot of
providers block such senders categorically due to all the spam robots
running on hijacked user PCs.

No, my mail server has a fixed IP and is sitting somewhere in a
datacenter, it shouldn't be in a dynamic-IP-DSL-provider range.
