platform/x86: nvidia-wmi-ec-backlight: Add force module parameter

2023-02-25T10:13:29+00:00

commit 0d9bdd8a550170306c2021b8d6766c5343b870c2 upstream.

On some Lenovo Legion models, the backlight might be driven by either
one of nvidia_wmi_ec_backlight or amdgpu_bl0 at different times.

When the Nvidia WMI EC backlight interface reports the backlight is
controlled by the EC, the current backlight handling only registers
nvidia_wmi_ec_backlight (and registers no other backlight interfaces).

This hides (never registers) the amdgpu_bl0 interface, where as prior
to 6.1.4 users would have both nvidia_wmi_ec_backlight and amdgpu_bl0
and could work around things in userspace.

Add a force module parameter which can be used with acpi_backlight=native
to restore the old behavior as a workound (for now) by passing:

"acpi_backlight=native nvidia-wmi-ec-backlight.force=1"

platform/x86/amd/pmf: Add depends on CONFIG_POWER_SUPPLY

commit 3004e8d2a0a98bbf4223ae146464fadbff68bf78 upstream.

It is reported that amd_pmf driver is missing "depends on" for
CONFIG_POWER_SUPPLY causing the following build error.

255 (LED_FULL) but we advertise a max_brightness of 1, so this should
be 1 (LED_ON).

platform/x86/amd: pmc: add CONFIG_SERIO dependency

Using the serio subsystem now requires the code to be reachable:

Add the usual dependency: as other users of serio use 'select'
rather than 'depends on', use the same here.

platform/x86/amd/pmf: Ensure mutexes are initialized before use

2023-01-30T13:30:57+00:00

As soon as the first handler or sysfs file is registered
the mutex may get used.

Move the initialization to before any handler registration /
sysfs file creation.

Likewise move the destruction of the mutex to after all
the de-initialization is done.

platform/x86/amd/pmf: Fix to update SPS thermals when power supply change

2023-01-30T13:30:57+00:00

Every power mode of static power slider has its own AC and DC power
settings.

When the power source changes from AC to DC, corresponding DC thermals
were not updated from PMF config store and this leads the system to always
run on AC power settings.

Fix it by registering with power_supply notifier and apply DC settings
upon getting notified by the power_supply handler.

platform/x86/amd/pmf: update to auto-mode limits only after AMT event

2023-01-30T13:30:57+00:00

Auto-mode thermal limits should be updated only after receiving the AMT
event. But due to a bug in the older commit, these settings were getting
applied during the auto-mode init.

Fix this by removing amd_pmf_set_automode() during auto-mode
initialization.
