Hello,
resuming from system suspend is intolerably slow in current mainline. I
am not the most patient person around, and I actually started out
bisecting this believing it was hanging... Turned out it wasn't really
hanging. It just took 15 seconds to wake up from suspend-to-ram.
Timing v3.9 I found that it used less than 3 seconds on this ancient
laptop I'm using.
Bisecting it ended up pointing to

rcu: Make RCU_FAST_NO_HZ take advantage of numbered callbacks
Because RCU callbacks are now associated with the number of the grace
period that they must wait for, CPUs can now take advance callbacks
corresponding to grace periods that ended while a given CPU was in
dyntick-idle mode. This eliminates the need to try forcing the RCU
state machine while entering idle, thus reducing the CPU intensiveness
of RCU_FAST_NO_HZ, which should increase its energy efficiency.

Being a big patch, I'm pretty sure that the problem is some minor
issue. But rather than trying to userstand this, just tried reverting
it on top of the current mainline and can confirm that this fixes the
regression. I'll leave the understanding to you :)
I'm attaching the revert patch as I had to fix a conflict, and may have
done something wrong there. I'm also attaching my .config.
Let me know if you need more information, or want me to try out proposed
fixes.

We don't want to back out the RCU_FAST_NO_HZ changes due to their
energy-efficiency benefits. So could you please try out Borislav's
patch below? He ran into the same issue a few weeks ago, and this
one fixed it for him.
Thanx, Paul

rcu: Expedite grace periods during suspend/resume
CONFIG_RCU_FAST_NO_HZ can increase grace-period durations by up to
a factor of four, which can result in long suspend and resume times.
Thus, this commit temporarily switches to expedited grace periods when
suspending the box and return to normal settings when resuming.

Yes, that's what I assumed. Just didn't know where to start dissecting
it...

Thanks! This patch did not make any difference for me by itself, for
pretty obvious reasons (I didn't time restore from hibernate - only from
suspend). But it pointed me in the right direction. Applying the
attached patch on top of that one fixed the problem.
Note that I'm also changing the restore from hibernate hook. According
to Documentation/power/notifiers.txt :
PM_POST_RESTORE An error occurred during restore from hibernation.
Device drivers' restore callbacks have been executed
and tasks have been thawed.
I believe Borislav must have meant
PM_POST_HIBERNATION The system memory state has been restored from a
hibernation image or an error occurred during
hibernation. Device drivers' restore callbacks have
been executed and tasks have been thawed.
in the above patch?
Please include some combination of these patches in your upcoming v3.10
fixes. Thanks.
Bjørn

Subject: [PATCH] rcu: Really switch to expedited grace periods for suspend
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
commit 587ff2cf ("rcu: Expedite grace periods during suspend/resume")
enabled expedited grace periods for hibernation, but not for suspend.
The same issue applies to both cases, so apply the same logic.
Restoring on post hibernation and post suspend, but not on post
restore, which only applies to the restore error case.

If I'm reading Documentation/power/notifiers.txt correctly, we only need
PM_HIBERNATION_PREPARE when we go to sleep (whatever hibernation method
we use) and PM_POST_HIBERNATION when we restore.
I don't think it matters for expediting RCU grace periods whether
we had an error during resume or not and I'd basically want to set
rcu_expedited to 0 unconditionally when resuming..
Hmm.

Well, that's not the way I read it. And testing also supports that.
Adding the above to your patch makes restore from suspend use < 3
seconds again. Using only PM_HIBERNATION_PREPARE had no effect on the
restore from suspend time, still measured at around 15 seconds on my
laptop.
Note that I did not test hibernation at all. But based on your patch I
assume the issue is exactly the same.

Yes, and I believe that's what PM_POST_HIBERNATION will achieve if I
read the docs correctly. But I guess this should be sanity checked via
Rafael or someone else knowing how these notifiers work.

Hmm, that could be because suspend.c does PM_SUSPEND_PREPARE and
hibernate.c does PM_HIBERNATION_PREPARE. So the statement
"PM_HIBERNATION_PREPARE The system is going to hibernate or suspend,"
is wrong.
Hi Rafael, it seems to me that if we need to do something for both sleep
methods, we have different notifier states and we have to add them both
if we want to do stuff for both, correct?

I get a ~10min boot delay with this patch:
[ 1.149676] system 00:01: [mem 0xf6000000-0xf6003fff] could not be reserved
[ 1.149724] system 00:01: Plug and Play ACPI device, IDs PNP0c02 (active)
[ 603.957670] pnp 00:02: [dma 4]
[ 603.957735] pnp 00:02: Plug and Play ACPI device, IDs PNP0200 (active)
This happens on my AMD FX-6100 system. I bisected the problem down to the same
commit and reverting it fixes the problem. Any ideas?

That does look pretty extreme! If you build with CONFIG_RCU_NO_HZ=n,
but without the revert, do you still get the delays?

With CONFIG_RCU_NO_HZ=n (and no revert) the system boots fine, no boot
delay. I also enabled some RCU debugging options (with
CONFIG_RCU_NO_HZ=y), but didn't see anything so far.

OK, good -- we at least have an easy work-around while I am tracking

Yes, this is incorrect. It should be "The system is going to hibernate".

Yes, that's correct.
The reason why is that hibernation does extra work between notifiers and
freezing drivers (also the "freezing" is not the same as "suspending").

And could you please try out the following patch?
Thanx, Paul
------------------------------------------------------------------------
rcu: Fix comparison sense in rcu_needs_cpu()
Commit c0f4dfd4f (rcu: Make RCU_FAST_NO_HZ take advantage of numbered
callbacks) introduced a bug that can result in excessively long grace
periods. This bug reverse the senes of the "if" statement checking
for lazy callbacks, so that RCU takes a lazy approach when there are
in fact non-lazy callbacks. This can result in excessive boot, suspend,
and resume times.
This commit therefore fixes the sense of this "if" statement.
