On some systems such as the IBM x3650 there are bits set in the upper half of the control values provided by the _PSS object. These bits are only relevant for cpufreq drivers that use IO ports which are not currently supported by the speedstep-centrino driver. The current MSR oriented code assumes that upper bits are not set and thus fails to work correctly when they are. e.g. the control and status value equality check fails even though the ACPI spec allows the inequality.

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.

Add in the support for Intel Enhanced Speedstep - MSR based transitions. With this change, the ACPI based support in speedstep-centrino can be deprecated and duplicate code in that driver can be marked for removal. Much easier to maintain and support this way. This also reduces the user misconfigurations and questions on which driver is to be used under which CPUs to support Enhanced Speedstep.

Some clean up and redsign of the driver. Mainly making it easier to add support for multiple sub-mechanisms of changing frequency. Currently this driver supports only ACPI SYSTEM_IO address space. With the changes below it is easier to add support for other address spaces like Intel Enhanced Speedstep which uses MSR (ACPI FIXED_FEATURE_HARDWARE) to do the transitions.

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.

It is silly to use non-static variable for writting zeroes to the file. And more seriously, foffset in core dump file dump function was incremented too much, so some parts of core dump were shifted by size of few phdrs and notes down, so although gdb was able to load that file, it did not make lot of sense - in my test case data pages were shifted down by about 900 bytes.
