Subject: [PATCH v4 0/3] Let other drivers react to platform profile changes
Date: Tue, 26 Oct 2021 14:08:32 -0500 [thread overview]
Message-ID: <20211026190835.10697-1-mario.limonciello@amd.com> (raw)
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
Changes from v3->v4:
* Simplify platform_profile_notify
- No need to check cur_profile as platform_profile_get does it
- No need to track ret as it's unused
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
