I understand the temptation, but two questions arise:
1) Shouldn't we actually audit to see if any of these are currently problems, 
and
2) Should the non-MAXSMP alloc_cpumask_var_node (currently a noop) zero the 
mask if __GFP_ZERO is set?

Thanks,
Rusty.

If we go that route we should conditionally clear the bitmaps in 
alloc_cpumask_var().  I don't think we do, though.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.

No. in that case, should cpumask_clear instead.

OK, here's what I've got in my tree.  Ingo, I think this should go in the
current -rc to avoid nasty bugs.

BTW, the original alloc_cpumask_var did zero; that was dropped after arguments
over efficiency and fitting with other interfaces, but I clearly had the old
semantics in my head for a while.

Thanks,
Rusty.

Subject: cpumask: alloc zeroed cpumask for static cpumask_var_ts
Date: Thu, 04 Jun 2009 14:01:31 -0700
From: Yinghai Lu <yinghai@kernel.org>

These are defined as static cpumask_var_t so if MAXSMP is not used,
they are cleared already.  Avoid suprises when MAXSMP is enabled.

How could this ever be a efficiency issue? If you allocate cpumasks so 
often that it's an efficiency problem, it would seem that you have bigger 
issues than the memset. You'll have to initialize them some other way 
anyway, so it's not like you can ever really avoid the dirty cachelines.

IOW, why isn't the fix just to clean up the horrible mess that is 
alloc_cpumask_var_node() once and for all. Why not something like this? 
The end result looks a lot simpler.

Or you could just add in that __GFP_ZERO there, and remove the memset. I 
don't care. But the current code just looks messy and crazy, and that 
FIXME is bogus. The end of the allocation needs to be cleared regardless.

some alloc_cpumask_var or alloc_cpumask_var_node calling are followed by 
cpumask_copy etc to assign the allocated cpuamsk_var_t.

about 66% calling are falling to that case.

Re: [PATCH] cpumask: alloc blank cpumask left over

[Yinghai Lu]

It seems we could remove that FIXME now.
cpumask_size is referred rather later.

Subject: [PATCH] use nr_cpumask_bits for cpumask_size calculating

so alloc_cpusmask_var could save some space when MAXSMP is used aka NR_CPUS
is 4096 on small conf system

Using __GFP_ZERO is equivalent to using memset() instead of 
cpumask_clear().  It's better to call cpumask_clear() or provide an API 
to alloc+clear.

Further, what about the non-MAXSMP case:


    static inline bool alloc_cpumask_var(cpumask_var_t *mask, gfp_t flags)
    {
            return true;
    }


We explicity clear on MAXSMP and rely on static initialization for the 
non-MAXSMP, laying a neat trap for anyone who makes the variable 
non-static.  Let's be less subtle that that.

-- 
I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.

or have zalloc_cpumask_var() ?

ick.  cpumask_var_node_zalloc() would be better.

Yes, the other functions were incorrectly named, but that's no reason
to incorrectly name these also.

Ok, this whole series looks much nicer than the hacky "add __GFP_ZERO in

ACK, as far as I'm concerned.

problem is that we would using alloc_cpumask_var and zalloc_cpumask in different case.

so we may need to change these name at the same time. otherwise will cause confusing. No?

No!!

First we need to get rid of all the old cpumask ops which assume NR_CPUS bits,
at least for any core or x86 code (the only arch which currently sets 
CONFIG_CPUMASK_OFFSTACK).

Sure.

Under these new semantics, yep.  Before:
	alloc_cpumask_var(&mask, GFP_KERNEL);
	// New operator only goes to nr_cpu_ids bits.
	cpumask_clear(mask);
	// Old operator uses all NR_CPUS bits.
	BUG_ON(cpus_weight(*mask) != 0);

Thanks,
Rusty.

I have a (more ambitious) patch for this in my queue, which weans it off this
entirely:

Subject: cpumask: avoid playing with cpus_allowed in powernow-k8.c
From: Rusty Russell <rusty@rustcorp.com.au>

It's generally a very bad idea to mug some process's cpumask: it could
legitimately and reasonably be changed by root, which could break us
(if done before our code) or them (if we restore the wrong value).

I use work_on_cpu, which is slightly less efficient than the old code,
but the code is complex enough that using smp_call_function_single()
is not trivial.

Please STOP USING THAT HORRIBLE "work_on_cpu()" crap.

Is there any reason you do that? We've had to fix up the fallout from that 
kind of crazy crap several times.

Just use a regular IPI. Use "smp_call_function_[single|many]()" instead.

See for example commit 01599fca6758d2cd133e78f87426fc851c9ea725, where 
another "work_on_cpu()" thing was broken.

I don't understand why you guys keep on using that _known_ bad function. 
The whole point of "work_on_cpu()" is for big, slow, and rare things. Not 
as a random "let's make that CPU do this".

So stop it.

work_on_cpu()'s definition could probably use a fat comment describing
why it sucks.

No, it should be renamed.

The problem is that it _sounds_ like a nice thing to do.

If it was called "slow_other_cpu_thread_switch_with_a_donkey_on_top()", I 
bet people wouldn't be so damn eager to use it.

Hope so, it's been in linux-next for ages.  The cpufreq maintainers seem to 
take a relaxed approach to patches, FWIW.

Yeah, it used to be *faster* than the stupid mug-own-cpumask code it was 
supposed to replace.   Then we hit all those deadlocks using keventd, and 
revulsion against YA per-cpu thread, and ended up with the current sucky 
version.

Simplicity of translation, laziness, and reluctance to break stuff.  And a
nicer API.

It's called here on cpu bringup, but I'll change it (the code doesn't sleep).  
I've a couple of others in my queue I'll look at similarly.

powernow_k8_target is problematic: it grabs a mutex.  cpufreq people, is this 
called often?

Thanks,
Rusty.

S06cpuspeed/2637 is trying to acquire lock (&(&dbs_info->work)->work (was: Re: [PATCH 4/6] x86/cpufreq: use cpumask_copy instead of =)

[Ingo Molnar]

[-- Attachment #1: Type: text/plain, Size: 207974 bytes --]


With a v2.6.30 based kernel i'm still getting a cpufreq lockdep 
warning:

 =======================================================
 [ INFO: possible circular locking dependency detected ]
 2.6.30-tip #10420
 -------------------------------------------------------
 S06cpuspeed/2637 is trying to acquire lock:
  (&(&dbs_info->work)->work){+.+...}, at: [<ffffffff8106553d>] __cancel_work_timer+0xd6/0x22a

 but task is already holding lock:
  (dbs_mutex){+.+.+.}, at: [<ffffffff8193d630>] cpufreq_governor_dbs+0x28f/0x335

This bug got introduced somewhere late in the .30-rc cycle, this box 
was fine before.

With so much of the cpumask stuff going through Ingo's trees, I've
taken the approach that it's easier to just let it continue to do so
rather than cherry picking the occasional cpufreq touching part.

Well, now that the main (and most risky) cpumask changes are over 
and done, it would be nice to go back to the regular model. Overlap 
in trees frequently causes bugs, friction and general unhappiness. 
There's nothing cpufreq related pending in any of the -tip trees in 
this cycle.

Yes.  It's the function that makes a frequency change
happen, so 5+ times per second per core isn't
unreasonable.

See the thread " [PATCH] remove rwsem lock from CPUFREQ_GOV_STOP call (second call site)" 
Though there's a report that the last patch posted still doesn't fix the problem,
so we still don't have a quick fix suitable for -stable.

It's this .. http://bugzilla.kernel.org/show_bug.cgi?id=13493
b14893a62c73af0eca414cfed505b8c09efc613c fixed one locking problem, but
introduced this as a side-effect.  The whole thing is a mess really.

Right, so we need to revisit this.  I'll leave it for the moment and put it on 
my TODO list.

i tested it and this blatant blind ripping out of a layer of locking 
uncovered the next layer:

I guess someone who knows the cpufreq code will have to fix the

Re: [PATCH] cpufreq: remove dbs_mutex

[Pallipadi, Venkatesh]

Mathieu Desnoyers sent a patch earlier that should address this problem.

No, that patch has _not_ fixed the regression:

The subsequent failure that Dave saw after that patch seemed to be related to dbs_mutex
http://lkml.org/lkml/2009/6/11/6

That should be be fixed by your original patch.

And how well will the two mix? This should really be pursued by the 
cpufreq people i think ...

Fix dead lock in cpufreq for CPU hotplug and suspend for 2.6.30.stable

[Thomas Renninger]

This is about the dead locks happening since cancel_delayed_work_sync()
got added to the ondemand/conservative governors.

I truncated a bit the CC list to most important people and mailing lists.

The patch is intended for 2.6.30 stable, but both patches together did
not get tested yet. If someone could verify this working now that
would be great.

I first wanted to provide something for .31 and then backport, but
it wouldn't patch clean anymore anyway and I don't want to wait
any longer.

Rafael: These should solve the regression bug:

[PATCH 1/2] CPUFREQ: Remove unneeded dbs_mutexes from ondemand and conservative governors

[Thomas Renninger]

Comment from Venkatesh:
...
This mutex is just serializing the changes to those variables. I could't
think of any functionality issues of not having the lock as such.

-> rip it out.

[PATCH 2/2] remove rwsem lock from CPUFREQ_GOV_STOP call (second call site)

[Thomas Renninger]

From: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>

Missed a call site for CPUFREQ_GOV_STOP to remove the rwlock taken around the
teardown. To make a long story short, the rwlock write-lock causes a circular
dependency with cancel_delayed_work_sync(), because the timer handler takes the
write lock.

Note that all callers to __cpufreq_set_policy are taking the rwsem. All sysfs
callers (writers) hold the write rwsem at the earliest sysfs calling stage.

However, the rwlock write-lock is not needed upon governor stop.

Here, for instance, there might be a problem if down_threshold is
changed concurrently with a store_up_threshold() call. See that there is
a test before the modification, and we need the mutex there for it to be
consistent.

Hrm, this is where we want the mutexes removed, but I fear this is
creating a race between sysfs_create_group (sysfs file creation) and
policy initialization...

I'm not convinced this mutex is not needed.

Here, for instance, there might be a problem if down_threshold is
changed concurrently with a store_up_threshold() call. See that there is
a test before the modification, and we need the mutex there for it to be
consistent.

Hrm, this is where we want the mutexes removed, but I fear this is
creating a race between sysfs_create_group (sysfs file creation) and
policy initialization...

I'm not convinced this mutex is not needed.

I am with Mathieu on this one. We can reduce the use of mutex here. But, it will still be needed. As I mentioned earlier, we need it to protect dbs_tuners getting changed from different CPUs at the same time. We also need it for dbs_enable change in start and stop from different CPUs. Otherwise dbs_enable increment/decrement and test will have races. I was playing with some changes for this. I should have a cleaner patchset later today...

Thanks,
Venki

I am with Mathieu on this one. We can reduce the use of mutex here. But, it will still be needed. As I mentioned earlier, we need it to protect dbs_tuners getting changed from different CPUs at the same time. We also need it for dbs_enable change in start and stop from different CPUs. Otherwise dbs_enable increment/decrement and test will have races. I was playing with some changes for this. I should have a cleaner patchset later today...

Thanks, I was rather quick with the conservative changes..., but
it should still be ok.

It should be assured that if userspace is doing:
echo x > down_threshold
echo y > up_threshold
that the first one will be served/finished first?

If userspace is writing different values for each core to the global 
conservative/ondemand tunables, or you have concurent userspace tools
trying to configure ondemand/conservative, it's a userspace bug.
It's confusing that ondemand/conservative allows per core reads/writes to
global variables and I hope to be able to provide something to change that in 
some days, maybe weeks.

If you still can think of a possible issue, a userspace scenario would
help.

This can be solved by moving this_dbs_info->enable incremenation
after sysfs_create_group.
But yes, I forgot that in my patch, thanks!

> I'm not convinced this mutex is not needed.
I am. Maybe it still takes some more thinking or step by step rework.
Finding an unintrusive, riskless short term solution for .30 is a challenge, 
though.

Thanks, I was rather quick with the conservative changes..., but
it should still be ok.

It should be assured that if userspace is doing:
echo x > down_threshold
echo y > up_threshold
that the first one will be served/finished first?

If userspace is writing different values for each core to the global 
conservative/ondemand tunables, or you have concurent userspace tools
trying to configure ondemand/conservative, it's a userspace bug.
It's confusing that ondemand/conservative allows per core reads/writes to
global variables and I hope to be able to provide something to change that in 
some days, maybe weeks.

If you still can think of a possible issue, a userspace scenario would
help.

This can be solved by moving this_dbs_info->enable incremenation
after sysfs_create_group.
But yes, I forgot that in my patch, thanks!

I am. Maybe it still takes some more thinking or step by step rework.
Finding an unintrusive, riskless short term solution for .30 is a challenge, 
though.

As I pointed out in an earlier reply, this patch is bogus and adds racy
data structure updates. It should not be merged.

Venkatesh is working on a proper fix.

Yes, sorry for not mentioning.

I looked at it again, but gave up after a while, I am not able
to provide a safe .30 fix for that, risk of making things worse
is too high...
My last thought was that the main culprit is that .governor() should
always be called with the rwsem held. I look at it further and try
to ease up things for future kernels, but can't spent that much
time on it currently.

Can you provide a userspace scenario (or tell which kind of event must
happen in between), that this would cause problems, please.

Imagine 

dbs_tuners_ins.sampling_down_factor = 0xd0000;
input = 0xabcd;

..then other threads can see 0xdabcd; if they read at "bad"
moment. Not on i386, but this is generic code (right?). Just use
atomic_t.

Rusty -

Did you ever get any ideas on a solution to this?  I'm
getting reports that the set_cpus_allowed_ptr() in
powernow_k8_target() is breaking with changeset
ebc79c4f8da0f92efa968e0328f32334a2ce80cf .  I haven't
changed the powernow_k8 code, so I suspect something
happened to set_cpus_allowed_ptr().
