2005-12-01[ACPI] Avoid BIOS inflicted crashes by evaluating _PDC only onceVenkatesh Pallipadi
Linux invokes the AML _PDC method (Processor Driver Capabilities) to tell the BIOS what features it can handle. While the ACPI spec says nothing about the OS invoking _PDC multiple times, doing so with changing bits seems to hopelessly confuse the BIOS on multiple platforms up to and including crashing the system. Factor out the _PDC invocation so Linux invokes it only once. http://bugzilla.kernel.org/show_bug.cgi?id=5483 Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

It is necessary to unload the processor idle handle for a short period of time to avoid for nasty races -- and we don't want to grab too many locks so that the idle handler continues to be speedy. http://bugzilla.kernel.org/show_bug.cgi?id=1958 Signed-off-by: Bruno Ducrot <ducrot@poupinou.org> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.de> Signed-off-by: Len Brown <len.brown@intel.com>

2004-01-30[ACPI] make # of performance states dynamicDominik Brodowski
from Dominik Brodowski
2004-01-30[ACPI] add _PDC supportDominik Brodowski
Add support for _PDC to the ACPI processor "Performance States library" (perflib). If this field is empty, a bogus entry is passed to the _PDC method so that the default (io) access is returned again. This patch is partly based on David Moore's patch to arch/i386/kernel/cpu/cpufreq/acpi.c, sent to the cpufreq mailing list on June 24th, 2003.

2004-01-30[ACPI] Move the /proc/acpi/processor/./performance output toDominik Brodowski
drivers/acpi/processor.c -- it's the same for all lowlevel drivers. By doing so, the lowlevel drivers no longer need to have access to struct acpi_processor. from Dominik Brodowski
2004-01-28[ACPI] acpi-cpufreq fixups from Dominik BrodowskiDominik Brodowski
- remove unnecessary usage of flags.performance - remove double check of _PPC in acpi-cpufreq driver as it's handled in drivers/acpi/processor.c already - remove unneeded EXPORT_SYMBOL - allocation of memory only for probed CPUs - add unregistration function to the core - fix OOPS when PST has core_frequency values of zero - fix cpufreq_get() output - fix /proc/acpi/processor/*/performance write support [deprecated]
2004-01-28[ACPI] update _PPC handling -- from Dominik BrodowskiDominik Brodowski
updates the _PPC handling. It is handled as a CPUfreq policy notifier which adjusts the maximum CPU speed according to the current platform limit.
