d5b562330ec766292a3ac54ae5e0673610bd5b3d. Sadly this just missed -rc4 by
something like 20 minutes..

Is there any reason to think this is a regression rather than a
one-time fluke?
If it really is a regression, additional debugging info would help.
The log excerpt in the email report doesn't show anything that happened
prior to the disconnect.

This is fixed by:
commit 1f5e31d7e55ac7fbd4ec5e5b20c8868b0e4564c9
Author: Andrea Righi <righi.andrea@gmail.com>
Date: Wed Feb 4 15:12:03 2009 -0800
fbmem: don't call copy_from/to_user() with mutex held
Avoid calling copy_from/to_user() with fb_info->lock mutex held in fbmem
ioctl().
fb_mmap() is called under mm->mmap_sem (A) held, that also acquires
fb_info->lock (B); fb_ioctl() takes fb_info->lock (B) and does
copy_from/to_user() that might acquire mm->mmap_sem (A), causing a
deadlock.
NOTE: it doesn't push down the fb_info->lock in each own driver's
fb_ioctl(), so there are still potential deadlocks elsewhere.

hello,
yes it's still present in -rc4
But I noticed that when I switch off KDE4.2 desktop effects, suspend to
ram is 100% reliable with 2.6.29-rc4
With 2.6.28, STR is 100% reliable with or without desktop effects
hope this helps,

Hi Etienne,
Can you try commenting out the calls to the radeon_suspend and
radeon_resume hooks in radeon_drv.c?

The patch in question has already been reverted. So while we
still need to track down the underlying problem with rlogin, it's
no longer a kernel regression.

For me it is reliable as soon as compositing/dri is disabled on 2.6.29.
On 2.6.28 it worked with compositing/dri *sometimes* - so 2.6.29 is the
first reliable kernel for me (when not using 3d).

I've just done ten suspend/resume cycles with 2.6.29-rc4 and this
message was not logged, so it's either gone away or else become much

Various suspend handlers were enabling irqs spuriously - fixed by recent patches in
-rc4. The warning above is consistent with the timekeeping code being surprised with
a premature irqs-enable.

There was no support for Chrome9 framebuffer before 2.6.28, so that is
a progress. However now that we have it, it doesn't work (at least for
me).... The BUG appearing seemed to be an mm-issue also reported by
others (see http://marc.info/?l=linux-kernel&m=123415925903748&w=2). I
don't know if it was there before 2.6.28. It doesn't look like any
solution has been merged to mainline.
It is certainly an issue, but I'm not sure if it's also a regression
from 2.6.28.

others (see http://marc.info/?l=linux-kernel&m=123415925903748&w=2). I
don't know if it was there before 2.6.28. It doesn't look like any
solution has been merged to mainline.
It is certainly an issue, but I'm not sure if it's also a regression
from 2.6.28.

First bad commit ? The commit adds a WARN_ON to getnstimeofday() when
it is called while timekeeping is suspended. So instead of pointing to
that commit can we please figure out WTF this happens?
Looking at the call stack this is pretty obvious:

powerbook_sleep() calls into the event interface which calls
gettimeofday() _AFTER_ timekeeping was suspended already so the
WARN_ON triggers.

Hi Dave,
I just tested that and I didn't change anything (cannot STR/resume with
desktop effect, STR/resume OK without desktop effects)
thanks,
Etienne

Hi Dave,
I created the following "shot in the dark" patch that solves my problem!
I looked at the change between 2.6.28 and .29rc, and only the
radeon_cp.c:radeon_cp_init_ring_buffer changes stroke my eyes (cause
it's called by radeon_cp_resume indirectedly)
I don't understand what i did and how this works, but it works for me
regards
Etienne

Dave, dri guys,
Could you take a look at this circular dependency please (below)? I
observe it when suspending laptop with radeon drm loaded and with
lockdep enabled. It seems that the root of the problem is that
various vm ops such as drm_vm_open, drm_mmap) are called with mm
semaphore taken, and take dev->struct_mutex. On the other hand,
drm_rmmap_locked is called with dev->struct_mutex, and calls mtrr_del
which depends on mm semaphore indirectly.
What do you think?

Yes, there are real lock inversions now due to the GTT mmap code. It's
going to be a pain to fix (I tried getting the mmap_sem -> struct_mutex
path to go away, but the fact that mmap_sem is held over the fault
handler pretty much kills that). It's high on the list, though.

Shouldn't it be possible to relax this given that in the fault()
handler, the mmap_sem() is taken in read mode only. This means that it
should be deadlock-safe (but still a little ugly) to take the mmap_sem()
in read mode when the struct mutex is held.
Another quick way to fix potential deadlocks, would be to take the
struct mutex in the following way in fault():
if (!mutex_trylock(&dev->struct_mutex)) {
needs_resched();
return VM_FAULT_NOPAGE;
}

Shouldn't we just revert it? The code does look to be broken.
It also looks like the interaction with that ever-buggy "nr_to_write"
thing are totally wrong. I can see that whole
if (!cycled) {
..
index = 0;
goto retry
}
doing all the wrong things: if we ever hit the combination of
"!cycled + nr_to-write==0", we're always screwed. It simply _cannot_ do
the right thing.
I dunno. That whole piece-of-sh*t function has been incredibly buggy this
release. The code is an unreadable mess, and I think that "cyclic" stuff
is part of the reason for it being messy and buggy. Please convince me
it's worth saving, or let me revert the whole stinking pile of crud?
Please?

Doh, I think you spotted the bug. I was going off on the wrong track.

Well... the cyclic stuff apparently gets used by some filesystems to do
data integrity stuff, so I think the problem addressed by my broken
commit maybe shouldn't be ignored.
Maybe you're being harsh on this function. It has been two thinko bugs
so far. Before this release cycle it seemed to have the record for the
most data integrity bugs in a single function...
How's this? Jan, can you test with the bdb workload please?
--
A bug was introduced into write_cache_pages cyclic writeout by commit
31a12666d8f0c22235297e1c1575f82061480029. The intention (and comments)
is that we should cycle back and look for more dirty pages at the
beginning of the file if there is no more work to be done.
But the !done condition was dropped from the test. This means that any
time the page writeout loop breaks (eg. due to nr_to_write == 0), we
will set index to 0, then goto again. This will set done_index to index,
then find done is set, so will proceed to the end of the function. When
updating mapping->writeback_index for cyclic writeout, we now use
done_index == 0, so we're always cycling back to 0.
This seemed to be causing random mmap writes (slapadd and iozone) to
start writing more pages from the LRU and writeout would slowdown.
With this patch, iozone random write performance is increased nearly
5x on my system (iozone -B -r 4k -s 64k -s 512m -s 1200m on ext2).

Doh, I think you spotted the bug. I was going off on the wrong track.

Well... the cyclic stuff apparently gets used by some filesystems to do
data integrity stuff, so I think the problem addressed by my broken
commit maybe shouldn't be ignored.
Maybe you're being harsh on this function. It has been two thinko bugs
so far. Before this release cycle it seemed to have the record for the
most data integrity bugs in a single function...
How's this? Jan, can you test with the bdb workload please?

A bug was introduced into write_cache_pages cyclic writeout by commit
31a12666d8f0c22235297e1c1575f82061480029. The intention (and comments)
is that we should cycle back and look for more dirty pages at the
beginning of the file if there is no more work to be done.
But the !done condition was dropped from the test. This means that any
time the page writeout loop breaks (eg. due to nr_to_write == 0), we
will set index to 0, then goto again. This will set done_index to index,
then find done is set, so will proceed to the end of the function. When
updating mapping->writeback_index for cyclic writeout, we now use
done_index == 0, so we're always cycling back to 0.
This seemed to be causing random mmap writes (slapadd and iozone) to
start writing more pages from the LRU and writeout would slowdown.
With this patch, iozone random write performance is increased nearly
5x on my system (iozone -B -r 4k -s 64k -s 512m -s 1200m on ext2).

Yes, this patch returns write performance of BDB workload back to
original numbers. Thanks for the fix.

3a4c6800. So this bug can be closed now...

P.S. One good thing about the commit 31a12666 was that made an
otherwise very hard to hit potential deadlock condition in ext4 very
easy to hit, and thus for us to detect and to fix. So, thanks. :-)

I've dropped it from the list of recent regressions, sorry for the slow

It turns out I didn't test this properly. The warning is only triggered
when I close and open the lid, not when I run 'snooze' to suspend and
hit Return to resume, as I did for my so-called testing of 2.6.29-rc4.
Whatever is triggering the warning is still present in 2.6.29-rc5.

Right, we probably need to stop sending input events from the PMU driver
when it's "suspended".
Ping me if I don't produce a patch tomorrow (ie, I forgot :-)

And it doesn't even do the job. Judging by this new trace, submitting
input events from the via-pmu resume function is still too early.

And it doesn't even do the job. Judging by this new trace, submitting
input events from the via-pmu resume function is still too early.

What's up Thomas ? We can't call gettimeofday() from a sysdev
suspend/resume ? That's a little bit too harsh no ?

Perhaps the ordering is wrong (ie. via-pmu resume happens bevore timekeeping
resume)?

Well, harsh or not is not the question here.
Fact is that you call gettimeofday() _before_ the timekeeping code has
resumed.
That's a simple ordering problem. timekeeping is in the sysdev class
as well and it's not the only sysdev which has explicit ordering
requirements.

Do we need suspend-resume priorities for sysdevs? Such that sysdevs
with a higher priority will always be suspended earlier and resumed later
than sysdevs with lower priority (or the other way around)?

In this case, maybe gtod should just return the frozen time (ie, last
time at the time of suspend) rather than WARN ?

And how do I control that ordering ?
I find that a bit fishy ... What about making gettimeofday() in the
timekeeping code work, just return a frozen snapshot of the value on
suspend instead ?

This might work, but there seem to be more problems like this (cpufreq vs
timekeeping for example).
I think we need a more general approach.

We had problems in the past where we just returned frozen time and the
calling code got surprised when the time jumped 5 hours ahead just a
few microseconds later.
What I find more fishy is the fact that the lid switch needs to be a
sysdev. It's a simple input event, which causes the user space code to
trigger the suspend sequence when the lid is shut.

What I find more fishy is the fact that the lid switch needs to be a
sysdev. It's a simple input event, which causes the user space code to
trigger the suspend sequence when the lid is shut.
Thanks,

Well, the PMU is a sysdev for lots of good reasons.. then it -also-
happens to provide us with the lid switch event.
I'm a bit surprised by the explanation about the code that is surprised
to see the time jump. IE. Code -will- see the time jump anyway. IE. I
don't see how making gtod blow instead of returning a frozen time will
make any difference whatsoever for code who get the time some time
before suspend and then some time after resume and see a 5 hours gap...
Cheers,
Ben.
