docs: update sysfs-platform_profile.rst reference

2021-05-20T19:44:13+00:00

The file name: Documentation/ABI/testing/sysfs-platform_profile.rst should be, instead: Documentation/userspace-api/sysfs-platform_profile.rst. Update its cross-reference accordingly.

ACPI: platform: Add balanced-performance platform profile

2021-02-24T13:52:41+00:00

Some devices, including most Microsoft Surface devices, have a platform profile somewhere inbetween balanced and performance. More specifically, adding this profile allows the following mapping on Surface devices: Vendor Name Platform Profile ------------------------------------------ Battery Saver low-power Recommended balanced Better Performance balanced-performance Best Performance performance Suggested-by: Hans de Goede Signed-off-by: Maximilian Luz Reviewed-by: Hans de Goede Signed-off-by: Rafael J.

ACPI: platform-profile: Introduce object pointers to callbacks

2021-01-27T17:45:29+00:00

Add an object pointer to handler callbacks to avoid the need for drivers to have a global variable to get to their driver-data struct.

ACPI: platform-profile: Drop const qualifier for cur_profile

2021-01-25T16:30:10+00:00

Drop the const qualifier from the static global cur_profile pointer declaration. This is a preparation patch for passing the cur_profile pointer as parameter to the profile_get() and profile_set() callbacks so that drivers dynamically allocating their driver-data struct, with their platform_profile_handler struct embedded, can use this pointer to get to their driver-data. Note this also requires dropping the const from the pprof platform_profile_register() function argument. Dropping this const is not a problem, non of the queued up consumers of platform_profile_register() actually pass in a const pointer.

ACPI: platform: Add platform profile support

2020-12-30T17:34:53+00:00

This is the initial implementation of the platform-profile feature. It provides the details discussed and outlined in the sysfs-platform_profile document. Many modern systems have the ability to modify the operating profile to control aspects like fan speed, temperature and power levels. This module provides a common sysfs interface that platform modules can register against to control their individual profile options.
