[CPUFREQ][8/8] acpi-cpufreq: Add support for freq feedback from hardware
Enable ondemand governor and acpi-cpufreq to use IA32_APERF and IA32_MPERF MSR
to get active frequency feedback for the last sampling interval. This will
make ondemand take right frequency decisions when hardware coordination of
frequency is going on.
Without APERF/MPERF, ondemand can take wrong decision at times due
to underlying hardware coordination or TM2.
Example:
* CPU 0 and CPU 1 are hardware cooridnated.
* CPU 1 running at highest frequency.
* CPU 0 was running at highest freq. Now ondemand reduces it to
some intermediate frequency based on utilization.
* Due to underlying hardware coordination with other CPU 1, CPU 0 continues to
run at highest frequency (as long as other CPU is at highest).
* When ondemand samples CPU 0 again next time, without actual frequency
feedback from APERF/MPERF, it will think that previous frequency change
was successful and can go to wrong target frequency. This is because it
thinks that utilization it has got this sampling interval is when running at
intermediate frequency, rather than actual highest frequency.

[CPUFREQ][1/8] acpi-cpufreq: software coordination and handle all CPUs in the group
This patchset has refresh/rebase of a bunch of patches/bugfixes related to
acpi-cpufreq that were sent earlier on this list.
patch 1/8
Patch that fixes a bug in swcoordination code in acpi-cpufreq
patch 2/8 through patch 7/8
Grand unification of ACPI based speedstep-centrino and acpi-cpufreq drivers.
ACPI allows P-state transitions in multiple ways. Like using IO ports or using
processor native method (MSR). Without this patch, IO port based P-state
transitions are handled in acpi-cpufreq driver and MSR based transitions on
Intel CPUs are handled in speedstep-centrino driver. Even though most of the
code in these two drivers should be similar, except for final changing/checking
of frequency (one driver does it using IO port and other does it through
MSR), we have duplicated code in these two drivers. There are also issues
around BIOSes supporting both MSR and IO port and which driver should be
loaded first in standard installations.
The patchset combines functionality of these two driver into acpi-cpufreq
driver. ACPI based functionality in speedstep-centrino is marked deprecated
and will be removed in future. speedstep-centrino will continue to work
on systems that depend on older non-ACPI table based P-state chanes.
* 2/8 - Patch that reorganizes the code in acpi-cpufreq, cleaning it up
a little and making it easier to add MSR support later.
* 3/8 - Pull in the MSR based transition support into acpi-cpufreq.
* 4/8 - Mark speedstep-centrino deprecated. Change the order in Makefile to
load acpi-cpufreq first and speedstep-centrino later, in cases where both
are configured in.
* 5/8 - lindent acpi-cpufreq.c
* 6/8 - Minor change to eliminate the check of current frequency on
notifications. We can use last set frequency instead.
* 7/8 - Make cpufreq->get of acpi_cpufreq work correctly again.
There will be a patch in future that removes ACPI based support in
speedstep-centrino in coming months.
patch 8/8
Add support for IA32_APERF and IA32_MPERF MSR and get the actual frequency
from these MSRs and use it to determine the next frequency target in ondemand
governor
This patch:
There is a bug in software coordination patch in acpi-cpufreq, due to which
frequency will only be set on first CPU of any coordinated group.
Bug identified by Denis, was not recognised earlier as there are no platforms
yet that use software coordination with acpi-cpufreq driver.

ACPI: SCI interrupt source override
The Linux group at Stratus Technologies has come across an issue with SCI
routing under ACPI. We were bitten by this when we made an x86_64 platform
whose BIOS provides an Interrupt Source Override for the SCI itself.
Apparently the override has no effect for the System Control Interrupt, and
this appears to be because of the way the SCI is setup in the ACPI code.
It does not handle the case where busirq != gsi.
The code that sets up the SCI routing assumes that bus irq == global irq.
So there is simply no provision for telling it otherwise. The attached
patch provides this mechanism.
This patch provided by David Bulkow, was tested on an i386 platform, which
does not use the SCI override, and also on an x86_64 platform which does
use an override.

These new functions take as arguments an ACPI EC command, a few bytes
to write to the EC data register and a buffer for a few bytes to read
from the EC data register. The old _read(), _write(), _query() are
just special cases of these functions.
Then unified the code in acpi_ec_poll_transaction() and
acpi_ec_intr_transaction() a little more. Both functions are now just
wrappers around the new acpi_ec_transaction_unlocked() function. The
latter contains the EC access logic, the two original
function now just do their special way of locking and call the the
new function for the actual work.
This saves a lot of very similar code. The primary reason for doing
this, however, is that my driver for MSI 270 laptops needs to issue
some non-standard EC commands in a safe way. Due to this I added a new
exported function similar to ec_write()/ec_write() which is called
ec_transaction() and is essentially just a wrapper around
acpi_ec_{poll,intr}_transaction().

ACPI _PDC and _CST methods.
Refer: Intel Processor Vendor-Specific ACPI: Interface Specification
http://www.intel.com/technology/iapc/acpi/downloads/302223.htm
With Processor Native C-state, we use 'MWAIT' instruction on the processor
to enter different C-states (C1, C2, C3). We won't use the special IO
ports to enter C-state and no SMM mode etc required to enter C-state.
Overall this will mean better C-state support.
One major advantage of using MWAIT for all C-states is, with this and
"treat interrupt as break event" feature of MWAIT, we can now get accurate
timing for the time spent in C1, C2, .. states.
