powerpc/cell/cpufreq: add spu aware cpufreq governor

[Arnd Bergmann]

=46rom: Christian Krafft <krafft@de.ibm.com>

This patch adds a cpufreq governor that takes the number of running spus
into account. It's very similar to the ondemand governor, but not as comple=
x.
Instead of hacking spu load into the ondemand governor it might be easier to
have cpufreq accepting multiple governors per cpu in future.
Don't know if this is the right way, but it would keep the governors simple.

Dave or other cpufreq people, can you take a look at this
and add an Acked-by when you're happy?

We have one prerequisite patch in the powerpc code (in spufs),
so should it get merged through powerpc.git?

I've got a basic question about this idea:

Does it throttle only idle spus or is there a single control for
the entire PPE + SPE complex?

I can think of many situations in our code where at certain times we
may only be able to keep N out of M spes occupied (because of how
we've expressed our task-specific parallelism), but we're counting on
the ones we're using running at full speed so that we can maintain our
real-time throughput.  (Our application does real-time signal
processing of continuously streaming data)

Is there a way to disable the "throttling SPEs" feature short of
configuring it out of the kernel?

There is one setting per socket, i.e. 8 SPUs and 1 PPU. In IBM speak,
that is slow mode, which would be C states in Intel speak.

There is also throttling (IBM), which can be applied to each core
seperately, and is the rough equivalent of T states in Intel terminology,
but it's almost useless for power saving purposes, so we don't do it
except for emergency (thermal overload) throttling.

By default, Linux always uses the "performance" governor, you have
to enable the spu aware governor manually to get the slow mode feature
in the first place.

Also, the idea of this code is to enter slow mode only if none of the
SPEs is constantly busy. As soon as you have a single thread hogging
one SPE, it will behave just like the performance governor, i.e.
do nothing.

It looks ok on a quick look through.  I'm wondering about the multiple governors
thing though. This came up at last years power management summit, but no-one has
mentioned it since.  I think it's possible we want to look at things like
this in the future, and not just for cell. I keep hearing mumblings about
future generations of x86's having dedicated coprocessors for certain tasks
that may benefit from the same thing.

That's fine with me. Conflicts should be minimal if any at all,
I've got nothing queued up which touches that part of Kconfig/Makefile

One question I do have though, is how userspace scripts are supposed
to know they're to echo cbe_spu_governor into the relevant parts of
sysfs.  I've not used anything with a cell. Do they expose the SPUs
as regular CPUs, or do they show up in a different part of the tree?

An SPU is very different from a CPU from the user perspective.
SPUs show up in /sys/devices/system/spus, and if a user wants to access
them, the "spufs" file system needs to be mounted in the system, by
convention on /spu.=20

Ok, that should be fairly simple to write scripts for.
All sounds good to me.

Actually, "cpufreq-set -g spu_governor" should be enough. (BTW, do we really
want this name?)

Do you have a better suggestion for the name? I don't think there was a
particularly strong reason to choose it over something else.

The issue I was pondering is whether to include "governor" in the name, for
we do not do this for the other governors. So here are my suggestions :)

	spu
	spuload
	spudemand

I found the problem now, there was an incorrect 'select CBE_CPUFREQ'
in the spudemand governor, but no 'depends on CPUFREQ', so it was
possible to build CBE_CPUFREQ without the base CPUFREQ support.

=46ixed in the current version, will post later.
