platform/x86: ideapad-laptop: add a mutex to synchronize VPC commands

2024-08-08T12:03:09Z

Calling VPC commands consists of several VPCW and VPCR ACPI calls. These calls and their results can get mixed up if they are called simultaneously from different threads, like acpi notify handler, sysfs, debugfs, notification chain. The commit e2ffcda16290 ("ACPI: OSL: Allow Notify () handlers to run on all CPUs") made the race issues much worse than before it but some races were possible even before that commit. Add a mutex to synchronize VPC commands.

platform/x86: ideapad-laptop: move ymc_trigger_ec from lenovo-ymc

2024-08-08T11:56:44Z

Some models need to trigger the EC after each YMC event for the yoga mode control to work properly. EC triggering consist of a VPC call from the lenovo-ymc module. Except for this, all VPC calls are in the ideapad-laptop module. Since ideapad-laptop has a notification chain, a new YMC_EVENT action can be added and triggered from the lenovo-ymc module. Then the ideapad-laptop can trigger the EC. If the triggering is in the ideapad-laptop module, then the ec_trigger module parameter should be there as well. Move the ymc_trigger_ec functionality and the ec_trigger module parameter to the ideapad-laptop module.

platform/x86/amd/pmf: Fix to Update HPD Data When ALS is Disabled

2024-08-08T11:53:35Z

If the Ambient Light Sensor (ALS) is disabled, the current code in the PMF driver does not query for Human Presence Detection (HPD) data in amd_pmf_get_sensor_info(). As a result, stale HPD data is used by PMF-TA to evaluate policy conditions, leading to unexpected behavior in the policy output actions. To resolve this issue, modify the PMF driver to query HPD data independently of ALS. Since user_present is a boolean, modify the current code to return true if the user is present and false if the user is away or if the sensor is not detected, and report this status to the PMF TA firmware accordingly. With this change, amd_pmf_get_sensor_info() now returns void instead of int.
