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 Signed-off-by: Len Brown --- arch/i386/kernel/acpi/Makefile | 2 +- arch/i386/kernel/acpi/cstate.c | 58 ------------------ arch/i386/kernel/acpi/processor.c | 75 +++++++++++++++++++++++ arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.c | 67 -------------------- arch/i386/kernel/cpu/cpufreq/speedstep-centrino.c | 12 ---- arch/ia64/kernel/cpufreq/Makefile | 5 ++ arch/ia64/kernel/cpufreq/acpi-cpufreq.c | 51 --------------- arch/ia64/kernel/cpufreq/acpi-processor.c | 67 ++++++++++++++++++++ arch/x86_64/kernel/acpi/Makefile | 5 ++ arch/x86_64/kernel/acpi/processor.c | 72 ++++++++++++++++++++++ 10 files changed, 225 insertions(+), 189 deletions(-) create mode 100644 arch/i386/kernel/acpi/processor.c create mode 100644 arch/ia64/kernel/cpufreq/acpi-processor.c create mode 100644 arch/x86_64/kernel/acpi/processor.c (limited to 'arch') diff --git a/arch/i386/kernel/acpi/Makefile b/arch/i386/kernel/acpi/Makefile index 267ca48e1b6c..d51c7313cae8 100644 --- a/arch/i386/kernel/acpi/Makefile +++ b/arch/i386/kernel/acpi/Makefile @@ -3,6 +3,6 @@ obj-$(CONFIG_X86_IO_APIC) += earlyquirk.o obj-$(CONFIG_ACPI_SLEEP) += sleep.o wakeup.o ifneq ($(CONFIG_ACPI_PROCESSOR),) -obj-y += cstate.o +obj-y += cstate.o processor.o endif diff --git a/arch/i386/kernel/acpi/cstate.c b/arch/i386/kernel/acpi/cstate.c index 4c3036ba65df..25db49ef1770 100644 --- a/arch/i386/kernel/acpi/cstate.c +++ b/arch/i386/kernel/acpi/cstate.c @@ -14,64 +14,6 @@ #include #include -static void acpi_processor_power_init_intel_pdc(struct acpi_processor_power - *pow) -{ - struct acpi_object_list *obj_list; - union acpi_object *obj; - u32 *buf; - - /* allocate and initialize pdc.

The code has been optimized to simplify and eliminate duplicated code, CPU stack use has been decreased by optimizing function parameters and local variables, and naming conventions across the manager have been standardized for clarity and ease of maintenance (this includes function, parameter, variable, and struct/typedef names.) All Resource Manager dispatch and information tables have been moved to a single location for clarity and ease of maintenance. One new file was created, named "rsinfo.c". The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to guarantee that the argument is not evaluated twice, making them less prone to macro side-effects. However, since there exists the possibility of additional stack use if a particular compiler cannot optimize them (such as in the debug generation case), the original macros are optionally available. Note that some invocations of the return_VALUE macro may now cause size mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to eliminate these. (From Randy Dunlap) Implemented a new mechanism to enable debug tracing for individual control methods. A new external interface, acpi_debug_trace(), is provided to enable this mechanism. The intent is to allow the host OS to easily enable and disable tracing for problematic control methods. This interface can be easily exposed to a user or debugger interface if desired. See the file psxface.c for details. acpi_ut_callocate() will now return a valid pointer if a length of zero is specified - a length of one is used and a warning is issued. This matches the behavior of acpi_ut_allocate().

This essentially entails recognizing that these processors support non-aligned memory transfers. Previously, all 64-bit processors were assumed to lack hardware support for non-aligned transfers. Completed conversion of the Resource Manager to nearly full table-driven operation. Specifically, the resource conversion code (convert AML to internal format and the reverse) and the debug code to dump internal resource descriptors are fully table-driven, reducing code and data size and improving maintainability. The OSL interfaces for Acquire and Release Lock now use a 64-bit flag word on 64-bit processors instead of a fixed 32-bit word. (Alexey Starikovskiy) Implemented support within the resource conversion code for the Type-Specific byte within the various ACPI 3.0 *WordSpace macros. Fixed some issues within the resource conversion code for the type-specific flags for both Memory and I/O address resource descriptors. For Memory, implemented support for the MTP and TTP flags. For I/O, split the TRS and TTP flags into two separate fields.

So we have to pad syscall table with sys_ni_syscall and that's where the trouble begins. .rept pseudo-op wants a constant expression for number of repetitions and subtraction of two labels (before and after syscall table) doesn't always get simplified to constant early enough for .rept. If labels end up in different frags, we lose. And while the frag size is large enough (slightly below 4Kb), the syscall table is about 1/3 of that. We used to get away with that, but the recent changes had been enough to trigger the breakage. Proper fix is simple: have a macro (CALL(x)) to populate the table instead of using explicit .long x and the first time we include calls.S have it defined to .equ NR_syscalls,NR_syscalls+1. Then we can find the proper amount of padding on the first inclusion simply by looking at NR_syscalls at that time. And that will be constant, no matter what. Moreover, the same trick kills the need of having an estimate of padded NR_syscalls - it will be calculated for free at the same time.

Formerly they were using pm_power_off, which is now being used by generic code. Make lasi.c use chassis_power_off instead of pm_power_off. Note, all machines need to call machine_power_off so that the switch can power off the machine, though halt -p may not necessarily be able to work properly on the machine.

Looking closely at the code, I found some possible issues in the way we setup the MDIO lines during suspend along with slight divergences from what Darwin does when resetting it that may explain the problem. That patch change these and the problem appear to be gone for me at least...

Currently timekeeping is enabled before the TSCs are synchronized, thus when the TSCs are synched (reset to zero), it appears that a number of lost ticks have occurred. This can cause premature expiry of timers and in extreme cases can cause the soft lockup detection to fire. This resolves issues reported by Andy Whitcroft as well as bug #5366 reported by Tim Mann.
