2008-04-22ACPICA: Fix to handle NULL package elements correctlyLin Ming
Fixed problem where NULL package elements were not returned to the AcpiEvaluateObject interface correctly. Instead of returning a NULL ACPI_OBJECT package element, the element was simply ignored, potentially causing a buffer overflow and/or confusing the caller who expected a fixed number of elements. http://bugzilla.kernel.org/show_bug.cgi?id=10132 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>

2008-04-22ACPICA: Fix for resource descriptor optimization issues for _CRS/_SRCBob Moore
Fixed a problem where resource descriptor size optimization could cause a problem when a _CRS resource template is passed to a _SRS method. The _SRS resource template must use the same descriptors (with the same size) as returned from _CRS. This change affects the following resource descriptors: IRQ/IRQNoFlags and StartDependendentFn/StartDependentFnNoPri. http://bugzilla.kernel.org/show_bug.cgi?id=9487 Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>

2008-04-22ACPICA: Fix for ACPI_HIDWORD macroBob Moore
Fixed a regression introduced in version 20071114. The ACPI_HIDWORD macro was inadvertently changed to return a 16-bit value instead of a 32-bit value, truncating the upper Dword of a 64-bit value. This macro is only used to display debug output, so no incorrect calculations were made.

2008-02-14ACPI, cpuidle: Clarify C-state description in sysfsVenkatesh Pallipadi
Add a new sysfs entry under cpuidle states. desc - can be used by driver to communicate to userspace any specific information about the state. This helps in identifying the exact hardware C-states behind the ACPI C-state definition. Idea is to export this through powertop, which will help to map the C-state reported by powertop to actual hardware C-state.

2008-02-13acpi: fix acpi_os_read_pci_configuration() misuse of raw_pci_read()Linus Torvalds
The raw_pci_read() interface (as the raw_pci_ops->read() before it) unconditionally fills in a 32-bit integer return value regardless of the size of the operation requested. So claiming to take a "void *" is wrong, as is passing in a pointer to just a byte variable. Noticed by pageexec when enabling -fstack-protector (which needs other patches too to actually work, but that's a separate issue).

2008-02-07ACPI: track opregion names to avoid driver resource conflicts.Thomas Renninger
Small ACPICA extension to be able to store the name of operation regions in osl.c later In ACPI, AML can define accesses to IO ports and System Memory by Operation Regions. Those are not registered as done by PNPACPI using resource templates (and _CRS/_SRS methods). The IO ports and System Memory regions may get accessed by arbitrary AML code. When native drivers are accessing the same resources bad things can happen (e.g. a critical shutdown temperature of 3000 C every 2 months or so). It is not really possible to register the operation regions via request_resource, as they often overlap with pnp or other resources (e.g. statically setup IO resources below 0x100). This approach stores all Operation Region declarations (IO and System Memory only) at ACPI table parse time. It offers a similar functionality like request_region and let drivers which are known to possibly use the same IO ports and Memory which are also often used by ACPI (hwmon and i2c) check for ACPI interference. A boot parameter acpi_enforce_resources=strict/lax/no is provided, which is default set to lax: - strict: let conflicting drivers fail to load with an error message - lax: let conflicting driver work normal with a warning message - no: no functional change at all Depending on the feedback and the kind of interferences we see, this should be set to strict at later time. Goal of this patch set is: - Identify ACPI interferences in bug reports (very hard to reproduce and to identify) - Find BIOSes for that an ACPI driver should exist for specific HW instead of a native one. - stability in general Provide acpi_check_{mem_}region. Drivers can additionally check against possible ACPI interference by also invoking this shortly before they call request_region. If -EBUSY is returned, the driver must not load. Use acpi_enforce_resources=strict/lax/no options to: - strict: let conflicting drivers fail to load with an error message - lax: let conflicting driver work normal with a warning message - no: no functional change at all Cc: "Mark M.

2008-02-02ACPI : Update T-state coordination after getting _TSD infoZhao Yakui
Accordint to ACPI spec, the _TSD object provides T-state control cross logical processor dependency information to OSPM. After the _TSD data for all cpus are obtained, OSPM will set up the T-state coordination between CPUs. Of course if the _TSD doesn't exist or _TSD data is incorrect , it is assumed that there is no T-state coordination and T-state is changed independently. Now there is no proper solution to update T-state coordination after one cpu is hotplugged. So this patch won't support hotplugged cpu very well.

2008-02-01ACPI: register ACPI Processor as generic thermal cooling deviceZhang Rui
Register ACPI processor as thermal cooling devices. A combination of processor T-state and P-state are used for thermal throttling. the processor will reduce the frequency first and then set the T-state. we use cpufreq_thermal_reduction_pctg to calculate the cpufreq limit, and call cpufreq_verify_with_limit to set the cpufreq limit. if cpufreq driver is loaded, then we have four cooling state for cpufreq control. cooling state 0: cpufreq limit == max_freq cooling state 1: cpufreq limit == max_freq * 80% cooling state 2: cpufreq limit == max_freq * 60% cooling state 3: cpufreq limit == max_freq * 40% after the cpufreq limit is set to 40 percentage of the max_freq, we use T-state for cooling. eg. a processor has P-state support, and it has 8 T-state (T0-T7), the max_state of the proceesor is 10: state cpufreq-limit T-state 0: max_freq T0 1: max_freq * 80% T0 2: max_freq * 60% T0 3: max_freq * 40% T0 4: max_freq * 40% T1 5: max_freq * 40% T2 6: max_freq * 40% T3 7: max_freq * 40% T4 8: max_freq * 40% T5 9: max_freq * 40% T6 10: max_freq * 40% T7 Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Thomas Sujith <sujith.thomas@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
