This patch below hangs my system on boot if I set nmi_watchdog=2 . It
shows the NMI as stuck then the system hangs .. nmi_watchdog=1 works
fine, and the system boots without any watchdog options ..

The machine is an Intel allagash development board, and it has two dual
core Pentium-M cpus. I attached the .config I used.

    [PATCH] i386: i386 make NMI use PERFCTR1 for architectural perfmon (take 2)

    Hello,

    This patch against 2.6.20-git14 makes the NMI watchdog use PERFSEL1/PERFCTR1
    instead of PERFSEL0/PERFCTR0 on processors supporting Intel architectural
    perfmon, such as Intel Core 2. Although all PMU events can work on
    both counters, the Precise Event-Based Sampling (PEBS) requires that the
    event be in PERFCTR0 to work correctly (see section 18.14.4.1 in the
    IA32 SDM Vol 3b).

    A similar patch for x86-64 is to follow.

    Changelog:
            - make the i386 NMI watchdog use PERFSEL1/PERFCTR1 instead of PERFSEL0/PERFCTR0
              on processors supporting the Intel architectural perfmon (e.g. Core 2 Duo).
              This allows PEBS to work when the NMI watchdog is active.

Should be fixed in commit e82f64e5bb0648a13630d752c35be1e7bd8bab96
(2.6.23-rc1 IIRC).

even with 2.6.21 IIRC.

I originally found the problem in 2.6.23-rc2 (actually latest git) so
whatever the problem is still exists ..

Could we put this on the known regressions list? It was added in 2.6.21,
and still exists in lastest git (as of 15 min. ago) ..

Bugzilla should be a better place for this bug.

I don't have enough time to track bugs after release, so old lists are not
maintained

Have you considered maintaining all the lists in Bugzilla? If you had a
search of open bugs they would just fall of the list as they get
closed..

Yes, I have considered it.

Bugzilla sucks when it comes to tracking things. There is
a regression field, but there are no difference between
2.6.22 and 2.6.23 regression.

Most people are reporting bugs through LKML:
- 23 regressions with reference to LKML
- 4 regressions with reference to Bugzilla

Unfortunately, the world is not perfect.

Is anyone interested in maintaining KR list for stable releases?

Presumably that's fixable.

But I think bugzilla is more appropriate for tracking longer-term bugs.  If
some problem has just popped up (or has just been discovered) then it's
best to try to knock it over with a quick email discussion.  If that
doesn't work out then the bug should be captured in bugzilla so that it
doesn't get lost.

The really important data which bugzilla will record are

a) the fact that the bug exists and

b) the identity of the person who can reproduce it and who will hopefully
work with us on fixing it.

I'm not sure that we need one, really.  Any bugs in a stable release can be
handled via email and/or bugzilla as we are presently doing?

What I'm concerned about is that regressions which we didn't fix are just
getting lost.  Is anyone taking care to ensure that they are getting
transitioned into bugzilla for tracking?

Here's how to use Bugzilla to track regressions between different
kernel versions:

Create a 2.6.22 regression bug and a 2.6.23 regression bug. All
regression bugs which are 2.6.22 regression bugs should block the
2.6.22 regression bug. All regression bugs which are 2.6.23 regression
bugs should block the 2.6.23 regression bug.

For example, say your master 2.6.22 regression bug tracking bug is #1.
When someone comes and files a new bug #2 which is a regression of
2.6.22, make bug #2 block bug #1. Then it is easy to see to track all
the 2.6.22 regressions.

To make it easier to remember what bug number tracks regressions for a
specific kernel, use a naming convention to create aliases for those
bugs.

Maybe this was a dumb assumption on my part, but I thought regressions 
were getting rolled over into the next release's list, if they are not 
solved?

I have tried to track all regressions, but it is a lot of work, so I
center on development kernels.

There are two lists (both unmaintained)

http://kernelnewbies.org/known_regressions_2622
http://kernelnewbies.org/known_regressions_2621

If you compare them, you will see "New regressions (submitted after
2.6.21 a.k.a. for -stable team)" - a long list of problems reported
after 2.6.21 release. I really do not have time to track issues in
stable releases.

Michal

I can copy all regression reports into Bugzilla after each release.

This sounds pretty easy :), thanks.

Unfortunately, Bugzilla is not a standard tool for handling bug reports.

The unresolved ones, that is?  If you can do that, it would be a very good
thing, IMO.

The main reason that I commented on this was because of your comment
below in the release emails,

Feel free to add new regressions/remove fixed etc.
http://kernelnewbies.org/known_regressions

And I was thinking, if these bugz need to transition over the bugzilla
anyway why not go straight there instead of via kernelnewbies .. People
would just get bugzilla accounts and open new bugz entry.

I not trying to force you into something , and ultimately it whatever is
easier for you.. Which was my main reason for commenting on it.

I think over time it would work like that , but I'm sure there's lots of
people who don't care about our bugzilla ..

Some people hates Bugzilla, and they do not want to use it.

Should we get the regression field fix before? Or had you planned on
just bypassing that completely ?

IMO solution proposed by David http://lkml.org/lkml/2007/8/27/21 seems
to be most reasonable.

Now that I'm looking at the kernel bugzilla .. If you set the kernel
version to 2.6.22 and set the "Regression" check box you could denote
the fact that it's a regression in that kernel version ..

I don't know if this URL is going to come out right,

http://bugzilla.kernel.org/buglist.cgi?query_format=advanced&short_desc_type=allwordssubstr&short_desc=&tree=Mainline&long_desc_type=substring&long_desc=&kernel_version_type=allwordssubstr&kernel_version=2.6.22&bug_status=NEW&bug_status=REOPENED&bug_status=ASSIGNED&emailassigned_to1=1&emailtype1=substring&email1=&emailassigned_to2=1&emailreporter2=1&emailcc2=1&emailtype2=substring&email2=&bugidtype=include&bug_id=&chfieldfrom=&chfieldto=Now&chfieldvalue=&regression=include&cmdtype=doit&order=Reuse+same+sort+as+last+time&field0-0-0=noop&type0-0-0=noop&value0-0-0=

That should be open bugs , kernel version 2.6.22, with the regression
check box set ..

So you may not need a master tracking bug ..

Daniel

Maximize the shame right? Post summaries of the regressions to LKML so
that everyone knows about the regression list, and what was broken and
who broke it ..

Judging from the regression lists and the regression reports we get 
post-release both on lkml and in the kernel Bugzilla we have much more 
than 100 unfixed regressions since 2.6.20 (plus regressions from older 
kernels...).

Tracking that many regressions is one problem (although getting all bug 
reports in Bugzilla would make this quite easy), but the bigger problem 
is how to get them debugged and resolved.

I've got some addition grips that I just noticed ..

http://bugzilla.kernel.org/show_bug.cgi?id=8945

I just file the above bugz entry ..

I know who caused the bug , Stephane Eranian <eranian@hpl.hp.com> ..
However I can't assign the bug to him. The field was greyed out and
forced the assignee as other_other@kernel-bugs.osdl.org ..

I tryed to CC: eranian@hpl.hp.com , and it said "no match" .. I guess
because he doesn't have an account.. So Stephane has no way to know the
bug exists , other than me emailing him ..

Also I couldn't check the "Regression" box until after I filed the bug..
It would be nice to file the bug in one action if it's possible .. I
don't know bugzilla well enough to know if that's possible tho.

It's a hassle when someone doesn't have a bugzilla account.  But there are
humans sitting behind bugzilla handling stuff (fsvo "human").  I've already
forwarded your bugzilla report to Stephane pointing out that he doesn't
have an account.

I screen 100% of new bugzilla reports and for those which I think need
attention (most), I will ensure that the appropriate parties get to see the
report.  I'll also verify that the "regression" state is correct and that
the provided info is sufficient-looking.  (It's amazing how many people
have trouble with the "Most recent kernel where this bug did not occur:"
question).

What I haven't been doing is ensuring that the Product and Component fields
are suitably set.  That's something which Natalie is now cleaning up.

I always fixed them when they were wrong, and I'd therefore be surprised 
if they were wrong for a significant amount of open bugs.

Indeed, now we need a predefined search "show regressions in 2.6.x" :)

So the plan is simple:
- copy all regressions into bugzilla after each release
- make sure that all regressions reported on lkml after realase hit bugzilla
- make sure that all regressions in bugzilla are marked as regression

When I read that question, it sort of feels like a mind bender. It's the
"did not occur" , most people are thinking "which version of the kernel
did I find this in", but it's asking the opposite ..

For bug #8945 I really don't recall the version of the kernel I ran when
it worked .. I had to do a bisect to get some clue about that ..
nmi_watchdog isn't something I use every time I boot (I should tho), and
I go through lots of kernels ..

In terms of regressions, it would be nice for the "Version" field to be
the kernel where the regression first showed up .. Like on bug #8945 I
put in 2.6.22 even tho I found the issue in 2.6.23-rc1 .. Is that
typically what the "Version" field is used for?

That would be great ;)

Daniel,

You mentioned you have a development board with a dual Pentium-M.

What are the exact family/model numbers?

What Bjorn points you at below is a fix that applies to
Intel Core Duo/Solo (Yonah) and Intel Core 2 series but not to
regular Pentium-M (no architectural perfmon there).

I have successfully booted 2.6.23-rc3 on PIII, Opteron and Intel Core 2
Duo with nmi_watchdog=2.

We've already reworked that question once because poeple were mucking up
the answer.  Without a lot of success.

Maybe it should be "Is this bug a regression?  If so, what was the most
recent kernel which didn't have this bug?".  But that requires that people
know what "regression" means.

Bearing in mind that many reporters aren't native English speakers, I'm
really struggling to find a simple and robust way to ask this question.

Maybe "Did any previous kernel work OK?  If so, what was the most recent
version of the kernel which didn't have this bug?"

hrm.  It doesn't matter much, really.  When people muck it up (or just
fail to answer that question) I go back and ask them again.  It only
takes 30 seconds...

Natalie is spending quite a bit of time with the bugzilla metadata,
queries, etc.  I'll shut up and let her tell us what changes we need in
this area.

Yep, that's another way to do it. The method I described earlier is
commonly used when you don't have the handy regression field in
bugzilla. The technique is handy for creating lists for tracking other
types of issues which don't necessarily fall into a component and you
don't want to bother customizing bugzilla.

I also suspect that there will be a number of common searches that
many people will find useful. With recent versions of bugzilla (3.0+)
you can share searches within groups, but it may be helpful to have a
wiki or some other page where useful searches can be stored, or one of
the templates edited to include those common searches.

The looks like a Core Duo. If that is really the case,
then commit e82f64e5bb0648a13630d752c35be1e7bd8bab96 from Bjorn
should fix your problem. I have it is my 2.6.23-rc3 tree.

Yet the model name looks strange. So we need to run one more test,
as the fam/model is not enough. What we need to check is whether or
not this processor implements architectural perfmon or not.

Could you please compile and run the attached program and send me 
the output?

Thanks.

The output below is all the output ..

Then you have a Core Duo processor and the commit from Bjorn should
fix the problem. If it does not, then there is something else wrong.
Unfortunately, I do not have a Core Duo machine to try and reproduce.

There must be something else wrong, cause the problem persists .. As I
said in past emails to Bjorn, I tested his commit in git, as well as the
latest git all with the same issue (as well as bisecting git)..

If the hardware is buggy then we need some way to determine that..

If this machine didn't support performance counters, what would happen
then?

Could you instrument check_nmi_watchdog() to verify that you terminate
this function? Normally there is a safety mechanism in there.

Another  possibility is that you get flooded with NMI interrupts and
do not make forward progress.

If you have an Local APIC and performance counters, then it will try and use it.
Otherwise, I suspect it tries the NMI_IO_APIC (nmi_watchdog=1).

Here is some output from my boot log,

md: raid1 personality registered for level 1
device-mapper: ioctl: 4.11.0-ioctl (2006-10-12) initialised: dm-devel@redhat.com
ip_tables: (C) 2000-2006 Netfilter Core Team

CPU#1: NMI appears to be stuck (0->0)!
CPU#2: NMI appears to be stuck (0->0)!
CPU#3: NMI appears to be stuck (0->0)!
Starting balanced_irq
<hangs>

So it does appear to make it out of the check_nmi_watchdog() function
even tho there is a problem with the watchdog .. "Starting balance_irq"
is in balanced_irq_init(). It usually hangs at this spot , but with
initcall_debug on it once hung a little further down ..

It seems like there might be some other interrupt going off too early,
that causes the system to hang..

As you can see from the log above, this system is a quad.. Two physical
cpus each with two cores.

I think I found the problem. As I suspected, it seems there is an assymetry
between the 1st end 2nd counter (just like what they have on P6 core). Yet
for architectural perfmon v1, this restriction is supposed to be lifted.

Unfortunately, a quick look at the errata document at
http://download.intel.com/design/mobile/SPECUPDT/30922212.pdf

for Core Duo shows bugs A49 as 'nofix':
  Core Duo processor has a bug which renders the enable bit (22) of
  PERFEVTSEL1 inoperative. The processor behaves like former P6 cores,
  the enable bit of PERFEVTSEL0 controls the activation of both counters

That explains why you get the 'NMI stuck' message when using PERFEVTSEL1.
I suspect when using PERFEVTSEL0, then NMI watchdog is not stuck. So it
is possible that in case NMI is stuck the code does not cleanly shutdown the
NMI interrupt and you get some spurious NMI interrupt later in the boot at
you are stuck because you are holding a lock. We need to look at the error
path of check_nmi_watchdog(). I glance through it and could not find the place
where the APIC vector is cleared.

Your patch switched the nmi from PERFEVTSEL0 to PERFEVTSEL1  (right?)..
So 0 works, 1 does not , for me anyway ..

As far as I can tell the check_nmi_watchdog() doesn't take locks, and it
can't safely share a lock with the NMI .. 

The patch below fixes the hang (not the stuck NMI) .. Not totally sure
why, but the cpus are stuck in a loop waiting for the endflag which
never comes .. This also plays with the nmi hz which might do
something.. /proc/interrupt doesn't show any nmi's either..

Bjorn,

It looks like we need to revisit the patch that makes the NMI
watchdog use the 2nd counter (PERFREVTSEL1/PMC1) for architectural
perfmon.

The Intel Core Duo processor has a bug (AE49) with the enable bit of the 2nd
counter not working. The Core 2 Duo/Quad processors also implement architectural
perfmon but they do not have the bug. Furthermore, they implement PEBS which
requires the use of the 1st counter.

I think we need to distinguish the 2 situtations. For Core Duo use the 1st counter,
for other architectural perfmon processor use the 2nd. That means we cannot simply
rely on X86_FEATURE_ARCH_PERFMON we need to check family/model number.

Thanks.

Here's a simpler patch that fixes the boot hang ..

We have to call off the IPI looping regardless of the check_nmi_watchdog
outcome..

What David suggested - is exactly what I was going to do, checking out
3.0 etc. Pretty much every post from everyone in this thread is an
action item.

I think we should start getting unsolved regressions in bugzilla, as a
"natural process". And maybe throwing them all in there even those
that got immediately resolved is probably a good thing - better than
to miss one. Either you do it Michal or dump it on me (I'm still doing
sorting out and cleaning things up, actually myself and Adrian - are
re-basing everything and getting rid of stale stuff).
Then I think bugzilla needs:
     adding more categories such as security, system calls (lots of
implementation suggestions for posix and non-posix ones), locking,
etc;
     improved searches - for sure, for example in addition to
pre-cooked queries make possible using "raw" queries directly on sql,
which will address misplaced bugs and will make categories more
dynamic;
    recipe database, for standard debugging requests and procedures
(serial console, getting sysreq traces, bisecting etc. - things to cut
and paste)
    user modifiable personal environment ("my bugzilla"), more of
morph type interface around the database.
... not mentioning all flaws and problems with current one (cannot get
back to home page, clear previous search, do certain updates in one
step and so on)

Regressions need to be tracked in effective manner, and I also noticed
counter intuitive question that we have now (the infamous "last
release when it _didn't_ happen") is clearly not the way to go, rather
 adding simple boxes "Was working in XX" and "Not working in XX" or
similar straightforward question.

In my opinion bugzilla is far from being a convenient tool. I suspect
that hating bugzilla comes down to having to deal with no
sophisticated interface that is inadequate - when so many nice and
slick tools and sites are around that we all used to.  I am also
investigating and checking out other bugzillas looking for good ideas.

Thanks,
--Natalie

Yes that is what the patch was doing and it was for a specific reason. On
a Core 2 Duo (which uses the 2nd generation of the architectural PMU), some
useful features (such as PEBS) requiree the use of counter 0 so we cannot
give it away to NMI.

Now on Core Duo, there is no PEBS anyway, so it is okay to use counter 0
for NMI. The problem is that the detection code in perfctr-watchdog.c
treats a Core Duo and a Core 2 Duo the same way as they both have the
X86_FEATURE_ARCH_PERFMON bit set.

I have attached a patch with handle the case of the Core Duo. Unfortunately,
I do not own one so I cannot test it. I would appreciate if you could
try re-applying my counter 0 -> 1 patch + this new one to see if you
have the problem with the NMI getting stuck.

The patch below is probably still needed to handle the case where you get
stuck.

Thanks.

Bugzilla is for tracking bugs, not for discussing possible
kernel features.

Tracking feature or implementation suggestions wouldn't make sense. 
Consider e.g. that there are several people on linux-kernel who often 
write what they think the kernel should do but who never write a single 
line of code themselves. There's no value in tracking such stuff.

What do you have in mind?

I've always been able to do any search I wanted using the "Advanced Search"
of Bugzilla. Well, just checking, it seems the search for the new
"regression" flag could be made easier, but that's not a general problem.

But what could be improved in the database would be to fix the 
charset problems for getting the RSS feeds working (#8774).  ;-)

Documentation makes sense, but it belongs into some place like the 
kernelnewbies wiki, not the Bugzilla itself.

Preferences settings plus saved searches already work.

The only thing that comes into my mind is that you cannot reassign a bug 
and change it's status in one step. But "flaws and problems" would IMHO 
be too hard an expression since it works fine with two updates.

Sounds like a good solution for the one question so many submitters get 
wrong.  :-)

Bugzilla isn't that bad and it has the advantage of being the most 
popular bug tracking system for open source projects, which means that 
most likely every kernel developer and many submitters have already used
a Bugzilla at some other project.

I'd say the success of any bigger Bugzilla change or switch to a 
different or writing of a new bug tracking system could be measured
by answering the following question:
  Will Linus Torvalds and David Miller use it?

True, but some of them are categorized as bugs from the reporter's
prospective, when they say "man page says" or "according to POSIX it's
wrong". I am going to push ones that are feature suggestions,
re-design suggestions, and some way implementation related out to the
site that Rick is going to help to maintain, which is more of
suggested projects list.

Yes, but some suggestions seem to make sense. How about evaluating it?
and if they are real making it a possible project for someone who
would do appropriate research, etc. And we move them from bugzilla
where they don't belong to a development arena.

I am going to look into the bugzilla software to start with, and see
if there is a way to expand it this way. we used to have such internal
tracking (unix based) at work, where we could compose pretty much
freelance queries, it is really not big deal for developers who script
and write huge regular expressions for their convenience every
day...just a vogue idea for now, trying to think how to minimize bugs
that get lost because of wrong bucket. Going manually through all of
them is not very effective.

Yes but you have to assume that everything is in the right place from
start, besides putting things into categories is often impossible
before some exchange with reporter and initial diagnostics. The worst
category so fas as I found is "other" (in every place where it
exists). Most of the "other" bugs haven't been touched, and some have
huge "SATA" letters in the description written in them :)

I agree :)

Right, so there should be convenient links to such. I know people like
Mauro maintains his own set of templates and he was the one to suggest
it, but later I found out myself that looking for serial console or
bisect instructions every time is cumbersome... I can't imagine
 making every maintainer to have to have his own, maybe some hate bug
stuff for this ("oh, not that again...")

> Preferences settings plus saved searches already work.
>
> What is missing?

I guess existing one is certainly good in many ways - just not good
enough for people to love it ;) Frankly, I see so many other bugzillas
that have better look and feel but there is no way we can change it
overnight...improving things according to feedback from maintainers
(after all the whole purpose is to give them what they need, even in
case if they don't need bugzilla at all! then it should be best
possible interface for bug maintainers ;), maybe try 3.0+ first and
see how much better we get...

Yea you can find many hidden buttons that you have to scroll down to
:) A little more ergonomics wouldn't hurt though..

Yes, and we should cater to them as well. I am totally agree with you
that tracking and fixing real bugs is the real goal, and interface is
only important as long as it serves the purpose, and not being a
culprit. We'll see how it will be evolving. (and I am evolving here
too - trying to find what's missing and how to make things work :)

I tested your patch .. The system doesn't hang, but the NMI seems to
disappear .. The check_nmi_watchdog() is not called, and the NMI never
actually starts firing .. Is that what you had intended?

If code behaves differently from how it should that is a bug. [1]

Fine with me, my point was simply that they don't belong into a
_bug_ tracker.

Is there any reasonable query that would be possible through SQL but

You need some kind of first level support that does some initial 
debugging and assigns the bug into the right category, and that will 
always be a manual task done by going through all new bugs.

I agree.

...to track very concrete feature-related TODO items.  One Issues &
Resolutions Database which I occasionally work with indeed distinguishes
between "bug", "new feature", "improvement", "task", whatever that
means.  The type of issue is the first question one is asked when one
enters a new issue.

'My' Linux kernel subsystem has a long virtual TODO list, with bugs,
missing features, and other kinds of items in it.  Since there is almost
no personnel, the list has a tendency to contain long-lived items.  Once
or twice or so I already added entries of the missing-feature kind to
bugzilla.kernel.org.  Doing this is questionable at the moment though
--- it adds noise to the database of actual bugs, since there is no way
to visually distinguish and filter bugs vs. missing features etc.

Of course, non-bug TODO items could as well be tracked elsewhere,
independently of bug tracking.  'My' subsystem has a wiki which could be
a good place for this.  Or I could start to post a TODO list on the
subsystem mailinglist in e.g. bimonthly intervals.


Al Boldi wrote in "Designers and Builders (was: Who wants to maintain KR

Design suggestions should really come from people who also know a lot
about the how-to.  This is even true to some degree about feature
requests.  Besides, I've got a feeling that regardless of the field of
τεχνη one works in, someone can only be a truly good designer if she or
he has also been a builder.

But back to the discussion.  A tracker is not a good tool for
brainstorming sessions, except perhaps for capturing conclusions after
the brainstorm, as far as they are suitable as input for actual work.

Also, "*allowing* others to implement it" has a strange ring to me.
Where I am around, there are always far too few people who fix things
and build things.  But very, very occasionally there is someone new who
wonders if there is an interesting TODO item which is perhaps in the
reach of his abilities.  Contributing a cleanup or an actual feature is
typically much easier than fixing an open, tracked bug.  (The bugs which
end up in the bugtracker are usually the difficult ones.)  The
contributor learns something and, in a rare turn of events, may
eventually become able and willing to join the bugfixing.

That's an interesting viewpoint, only programmers have useful 
thoughts... ignoring users, people who have CS degrees but don't code, 
etc. I would think there's value in any rational suggestions which 
include technical justification for the suggestion.

Exactly right.

The important part in designing isn't the how-to but rather understanding the 
concepts involved.  Once you have the concepts straight, implementation 
becomes a matter of which path to take.

Agreed.  But when I responded to this thread by changing the subject, because 
I felt it was somewhat OT to tracking, I meant to question the mentality of 
trying to nullify design suggestions for the mere reason of not submitting a 
prototype.  Now, prototyping is a great way to refine your end-product, but 
it's a terrible waste of time in terms of articulating design-goals.

IMHO, in the interest of keeping ahead of the competition, we should 
encourage people to express their design suggestions instead of discouraging 
them.


Thanks!

This patch still has the stuck NMI .. Essentially the same thing that
happened without the patch..

Feel free to keep sending patches, I'll test them all ..

Ok, looks like deaulting to P6 does not quite work.

Here is a new version. This time I used a different approach.
I am must admit I am a bit puzzled by the duplication of information
between the wd_ops and the nmi_watchdog_ctlblk structure. My understanding
is that thelater is used as a cache for the info that needs to be per-cpu.

The wd_ops provides the MSR to use for the counter, yet all the setup_*()
routines hardcode the MSR. Not sure why?

In this patch, the setup_*() routine now extract the MSR from the wd_ops
to copy them into the nmi_watchdog_ctlblk. This is not done for P4 because
of the special and ugly case of HT. 

With this approach, we can now create a custom wd_ops for CoreDuo that is
a clone of the intel_arch_wd_ops, except for the MSR.

Could you try this one instead?

Thanks.

Yeah, that's bad .. For instance, if those had all been centralized
Bjorn wouldn't have needed to fix those up later..

So I tested your patch unchanged and the system boots, and the
check_nmi_watchdog() passes .. However, the nmi stops ticking right
after bootup,

That's because MSR_P6_PERFCTR0 is the same as MSR_ARCH_PERFMON_PERFCTR0.
But I'd personally add that change anyway, as it makes the code less
tricky and the compiler should optimize it away.

> something to do with the nmi hertz adjustment that happens after

Hm hm, does the same thing (watchdog stuck after check) happen with
older kernels, ie. those before Stephane's changeset that made it use
PERFCTR1?

Maybe you could "activate" the Dprintk in write_watchdog_counter32() to
see which value gets written to the MSR? (I don't see any switch to
activate it, so maybe just s/Dprintk(/printk(KERN_WHATEVER / ?)

Thanks,
Björn

I noticed the frequency gets turned down after check_nmi_watchdog() is

If you look at the LOC values you'll notice a lot of time has passed,
with only one NMI and on only one cpu ..

It's possible this is something else completely tho ..

Here's the only lines printed,

It's once per second if the cpu is 100% busy, if it's just idling and
halted, the performance counters won't be increased.

With the same load on the box? Maybe some other changes caused the box
to behave differently (say, CFS), regarding eg. load distribution
amongst the cores.

At least from the interrupt side, that box looks pretty idle, so that's
expected I'd say.

Ok, dumb I am.

The "interesting" call from p6_rearm passes NULL as desc, and thus the
printk is never called that way. But before we start flooding your logs,
could you just hog all cores with a simple cpu hog and check if that
causes the NMI counter to increase at about 1 Hz? If that doesn't work,
we can go back to that debug output.

Didn't know that .. I ran hackbench while watching /proc/interrupts ,
and it ticks along ok on some cores .. 

The acid test was running an application that hangs the system, and it
caught it (although the system didn't recover from the lockup..) ..

It must not have been the same load considering everything else.

I'm satisfied that Stephane's last patch fixes it ..

It only ticks when the CPU is not idle. If you want to see the "operating 
frequency" run a main(){for(;;;);} for each core.

Great. Can someone send a final version with proper Changelog and Signed-off-by 
please? Thanks.

Hello,

Here is a patch to fix the NMI watchdog problem on CoreDuo processor.
I think we still need Daniel's patch to make the error path (when you
are stuck) do the right cleanup.


Changelog:
	- fix the NMI watchdog on Intel CoreDuo processor whereby the
	  kernel would get stuck during boot. The issue is related to
	  errata AE49, where the PERFEVTSEL1 counter does not have a
	  working enable bit. Thus it is not possible to use it for NMI.
	  The patch creates a dedicated wd_ops for CoreDuo which falls
	  back to using PERFEVTSEL0. The other Intel processors supporting
	  the architectural PMU will keep on using PERFEVTSEL1 as this
	  allows other subsystems, such as perfmon, to use PERFEVTSEL0 for
	  PEBS monitoring in particular.
	  Bug initially reported by Daniel Walker.

Signed-off-by: Stephane Eranian <eranian@hpl.hp.com>

Thanks.

Can that other patch please be submitted too?

"Contributing a cleanup" is what the Kernel Janitor Project
already offers.

But "Contributing an actual feature" is much harder:

You need a feature:
- with a realistic chance of being included and
- hard enough that the person suggesting it doesn't simply implement it
  himself instead of requesting it and
- easy enough that a newbie can implement it.

And the code should then be in a reasonable shape for being merged.

IMHO that's nearly impossible.

Realistically, offering a TODO item for a feature would require the one 
proposing it to do an amount of mentoring work that is not smaller than 
the amount of work he had to spend if implementing it himself.

This might be worth it if you know for sure the person you are mentoring 
stays active after completion of the feature - but this assumption is 
too often not true.

I didn't say this - users can always suggest features.

But open source is driven by coders, not by dreamers who want to offload 
the work of implementing their whacky ideas to other people instead of 
getting their ass up and doing it themselves.

So if the user doesn't implement it himself, and no developer is 
interested in doing the work after it got posted to linux-kernel,
an idea is most likely not worth being tracked.

Helping to bring it into shape may be one of the easier pastimes of a
gateway person.  (Can be done after mindnumbing day job.)

Adding a feature is not just a matter of amount of work, it is also a
matter of motivation and inspiration.  So, even if it remains a one-off
project, at least that feature came into life.

But besides these remarks I have to agree with your view, overall.
