Hi Mario, On Tue, Nov 5, 2024, at 10:32 AM, Mario Limonciello wrote:Currently there are a number of ASUS products on the market that happen to have ACPI objects for amd-pmf to bind to as well as an ACPI platform profile provided by asus-wmi. The ACPI platform profile support created by amd-pmf on these ASUS products is "Function 9" which is specifically for "BIOS or EC notification" of power slider position. This feature is actively used by some designs such as Framework 13 and Framework 16. On these ASUS designs we keep on quirking more and more of them to turn off this notification so that asus-wmi can bind. This however isn't how Windows works. "Multiple" things are notified for the power slider position. This series adjusts Linux to behave similarly. Multiple drivers can now register an ACPI platform profile and will react to set requests. To avoid chaos, only positions that are common to both drivers are accepted when the legacy /sys/firmware/acpi/platform_profile interface is used. This series also adds a new concept of a "custom" profile. This allows userspace to discover that there are multiple driver handlers that are configured differently. This series also allows dropping all of the PMF quirks from amd-pmf. v4: * Drop the list; iterate classes * Drop patches that didn't make sense without list * Cover alienware-wmi as well (recently merged to platform-x86/for-next) * Drop requirement for balanced * Rename platform-profile class members to 'profile', 'options', 'name' * Drop the name in /sys/class/platform-profile and just use ida value.

The thinkpad-acpi and amd-pmf classes show up. I can tweak them individually and 'custom' shows up under firmware/acpi/platform_profile. I tried various combo's and didn't see any issues. If you have any recommendations of things to try let me know. Tested-by: Mark Pearson <mpearson-lenovo@xxxxxxxxx> Mark
Thanks for testing! The fact that Lenovo and ASUS are both doing this with recent laptops makes it all the stronger of a case to do it rather than let them race for who gets the coveted platform profile slot.
If you've already tried mixing and matching combinations that's all I was going to suggest.
I'll wait for Armin's review and then I'll respin with the tags and small things you and Ilpo found.
BTW if I missed any important feedback of yours from v3 please let me know. It was a lot of overhaul to switch to this way of doing things and a lot of it didn't make sense anymore.
