This looks like it wasn't a regression, but some other compile/install 
issue. See

	http://marc.info/?l=linux-kernel&m=127274294422719&w=2

where he reports that his self-compiled 2.6.33 doesn't boot either. 

There's some confusion about .config, but it might well be an install 
problem too (in fact, that sounds more likely - the original bug-report 
seems to reboot before the kernel has really even booted - it apparently 
hasn't done the graphics mode switch by the early bootloader)

2.6.35-rc3: Reported regressions 2.6.33 -> 2.6.34

[Rafael J. Wysocki]

[NOTES:
 * This report has been delayed, because I had to go through all of the
   entries and filter out the fixed ones, invalid ones etc.  Of course, I might
   have missed some, but hopefully not too many.
 * E-mail reports from the last 7 days are not included.]

This message contains a list of some post-2.6.33 regressions introduced before
2.6.34, for which there are no fixes in the mainline known to the tracking team.
If any of them have been fixed already, please let us know.

If you know of any other unresolved post-2.6.33 regressions, please let us know
either and we'll add them to the list.  Also, please let us know if any
of the entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

So what are our options? We can revert the SLUB conversion patch for now 
but I still can't see what's wrong with it...

I haven't been able to reproduce this either on my Core 2 machine.

Yanmin, does something like this help on your machines? I'm thinking false 
sharing with some other per-CPU data structure that happens to be put in 
same percpu slot as struct kmem_cache_cpu...

I also don't know why. The original patch looks good.

Mostly, the regression exists on Nehalem machines. I suspect it's related to
hyper-threading machine.

A quick testing doesn't show any help.

I did a new testing. After the machine boots, I hot remove 8 hyper-threading cpu
which means last 8 are just cores. The regression between 2.6.33 and 2.6.34-rc becomes
small.

My opinion is we needn't revert the patch, but still keep an eye on it when testing other
new RC kernel releases. One reason is volanoMark and netperf have no such regression.
Is it ok?

OK, so does anyone know why hyper-threading would change things for
the per-CPU allocator?

>> Yanmin, does something like this help on your machines?

So it's unlikely to be false sharing, I suppose.

We need to get this fixed. In my experience, it's pretty common that
slab regressions pop up only in one or few benchmarks. The problem is
likely to pop up in some real-world workload where it's even more
difficult to track down because basic CPU profiles don't pin-point the
problem.

Do we have some Intel CPU expert hanging around here that could
enlighten me of the effects of hyper-threading on CPU caching? I also
wonder why it's showing up with the new per-CPU allocator and not with
the homebrewn one we had in SLUB previously.

OK, so does anyone know why hyper-threading would change things for
the per-CPU allocator?

So it's unlikely to be false sharing, I suppose.

We need to get this fixed. In my experience, it's pretty common that
slab regressions pop up only in one or few benchmarks. The problem is
likely to pop up in some real-world workload where it's even more
difficult to track down because basic CPU profiles don't pin-point the
problem.

Do we have some Intel CPU expert hanging around here that could
enlighten me of the effects of hyper-threading on CPU caching? I also
wonder why it's showing up with the new per-CPU allocator and not with
the homebrewn one we had in SLUB previously.

My wild speculation is that previously the cpu_slub structures of two
neighboring threads ended up on the same cacheline by accident thanks
to the back to back allocation.  W/ the percpu allocator, this no
longer would happen as the allocator groups percpu data together
per-cpu.

Thanks.

Yanmin, do we see a lot of remote frees for your hackbench run? IIRC,
it's the "deactivate_remote_frees" stat when CONFIG_SLAB_STATS is
enabled.

I'm not familiar with the details or scales here so please take
whatever I say with a grain of salt.  For hyperthreading configuration
I think operations don't have to be remote to be affected.  If the
data for cpu0 and cpu1 were on the same cache line, and cpu0 and cpu1
are occupying the same physical core thus sharing all the resources it
would benefit from the sharing whether any operation was remote or not
as it saves the physical processor one cache line.

Thanks.

Even if the cacheline is dirtied like in the struct kmem_cache_cpu case? 
If that's the case, don't we want the per-CPU allocator to support 
back to back allocation for cores that are in the same package?

Btw, I focused on remote frees initially before I understood what you 
actually meant and scetched the following untested patch to take advantage 
of the fact that struct kmem_cache_cpu doesn't fill a whole cache line. It 
tries amortize remote free costs by "queuing" objects. It would be 
interesting to see if it helps here (or in the other SLUB regressions like 
netperf and the famous Intel one).

If my hypothesis is the case, I don't think dirtying or not would
matter.  It's about two cpus sharing a cache line which usually is a
bad idea but in this case happens to be a good idea because the two
cpus sit on the same cache.

I think it's probably gonna be an over-engineering effort.  W/ percpu
allocator the rest of the cacheline would likely be occupied by
another percpu item for the cpu, so it's not really wasted.  It's just
used differently.  It would be good if we have a way to better pack
small hot ones (for the same cpu) into the same cachelines but I don't
think it would be wise to interleave stuff from different cpus.  It's
not like there's only single way to save a cacheline after all.

Thanks.
