ACPI / processor: Make acpi_cpu_soft_notify() process CPU FROZEN events

2014-08-06T20:22:03Z

CPU hotplug happens during S2RAM and CPU notify event will be CPU_XXX_FROZEN. acpi_cpu_soft_notify() ignores to check these events. This also may make acpi_cpu_soft_notify() fall into sleep during CPU_DYING/STARTING_FROZEN events which don't allow callbacks to sleep. This patch is to fix it.

ACPI / processor: Fix STARTING/DYING action in acpi_cpu_soft_notify()

2014-05-16T14:36:03Z

During CPU online/offline testing on a large system, one of the processors got stuck after the message "bad: scheduling from the idle thread!". The problem is that acpi_cpu_soft_notify() calls acpi_bus_get_device() for all action types. CPU_STARTING and CPU_DYING do not allow the notify handlers to sleep. However, acpi_bus_get_device() can sleep in acpi_ut_acquire_mutex(). Change acpi_cpu_soft_notify() to return immediately for CPU_STARTING and CPU_DYING as they have no action in this handler.

ACPI: Remove duplicate definitions of PREFIX

2014-03-19T01:01:57Z

We already have a macro for PREFIX of "ACPI: " in drivers/acpi/internal.h, so remove the duplicate ones in ACPI drivers when internal.h is included. Signed-off-by: Hanjun Guo Signed-off-by: Rafael J. Wysocki

ACPI / processor: use ACPI_COMPANION() to get ACPI device

2013-12-07T00:41:01Z

Use ACPI_COMPANION() to get an ACPI device instead of acpi_bus_get_device() in the processor driver. Signed-off-by: Lan Tianyu [rjw: Changelog] Signed-off-by: Rafael J. Wysocki

ACPI / processor: Do not request ACPI cpufreq module directly

2013-10-29T23:00:30Z

Function acpi_processor_load_module() used by the ACPI processor driver can only really work if the acpi-cpufreq module is available when acpi_processor_start() is executed which usually is not the case for systems loading the processor driver module from an initramfs. Moreover, that used to be a hackish workaround for module autoloading issues, but udev loads acpi-cpufreq just fine nowadays, so that function isn't really necessary any more. For this reason, drop acpi_processor_load_module() entirely. Signed-off-by: Rafael J. Wysocki

ACPI / processor: Remove acpi_processor_get_limit_info()

2013-08-13T10:11:22Z

acpi_processor_get_limit_info() is only called in the __acpi_processor_start() and what it does actually is just to check pr->flags.throttling and set limit. The pr pointer has been checked in the __acpi_processor_start() before acpi_processor_get_limit_info() being called. It doesn't make sense still to keep it as a function. So move code to __acpi_processor_start() and remove acpi_processor_get_limit_info(). Signed-off-by: Lan Tianyu Acked-by: Zhang Rui Signed-off-by: Rafael J. Wysocki

ACPI: Remove the old /proc/acpi/event interface

2013-07-15T11:56:36Z

It is quite some time that this one has been deprecated. Get rid of it. Should some really important user be overseen, it may be reverted and the userspace program worked on first, but it is time to do something to get rid of this old stuff...
