[PATCH v3 0/3] Let other drivers react to platform profile changes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently only one driver can register as a handler for a platform profile.

This limitation means that if multiple drivers want to react to platform
profile changes that they will need to directly interact with individual
drivers.

Instead introduce a notification flow that drivers can register for event
changes.  The idea is that any driver that wants to can:
1. read the current profile
2. set up initial values
3. register for changes
4. react to changes

Note: currently this is accomplished by changing platform_profile_get to a
symbol that all drivers can get during initialization.  Another idea for
this may be to change:

`int platform_profile_register_notifier(struct notifier_block *nb)`

into:

`int platform_profile_register_notifier(struct notifier_block *nb,
					enum *profile)`

IOW return the current profile value as an out argument as part of
registration. I don't have a strong opinion.

Changes from v2->v3:
 * Add patches to avoid collisions in hp-wmi and asus-wmi symbols

Mario Limonciello (3):
  platform/x86: hp-wmi: rename platform_profile_* function symbols
  platform/x86: asus-wmi: rename platform_profile_* function symbols
  ACPI: platform_profile: Add support for notification chains
