Adds support for setting various power states of TUF keyboards. These states are combinations of: - boot, set if a boot animation is shown on keyboard - awake, set if the keyboard LEDs are visible while laptop is on - sleep, set if an animation is displayed while the laptop is suspended - keyboard (unknown effect) Adds two sysfs attributes to asus::kbd_backlight: - kbd_rgb_state - kbd_rgb_state_index Signed-off-by:

Some more recent TUF laptops have both fan_boost and thermal_throttle. The key code for Fn+F5 is also different and unmapped. This patch adjusts the asus_wmi_handle_event_code() match to match for both 0x99 and 0xAE, and run both mode switch functions for fan_boost and/or thermal_throttle if either are available. It is required that both are tried, as in some instances the ACPI set-method for one may not have any code body within it even though it was returned as supported by the get method. Signed-off-by:

Simplify tablet-mode-switch handling: 1. The code is the same for all variants, the only difference is the dev_id and notify event code. Store the dev_id + code in struct asus_wmi and unify the handling 2. Make the new unified asus_wmi_tablet_mode_get_state() check dev_id has been set and make it a no-op when not set. This allows calling it unconditionally at resume/restore time 3. Simplify the tablet_mode_sw module-param handling, this also allows selecting the new lid-flip-rog type through the module-param.

The settings for these attributes can be read from the device, this is now done instead of reading a stored value from module. The stored value is also removed. This means the simpler asus_wmi_dev_is_present() can be used in *_check_present() - it is not an error for these methods to be missing. The _write() functions have their bodies shifted in to *_store() which simplifies things further. Signed-off-by:

The transition to auto-mode happens when the PMF driver receives AMT (Auto Mode transition) event. transition logic will reside in the PMF driver but the events would come from other supported drivers[1]. The thermal parameters would vary between when a performance "on-lap" mode is detected and versus when not. The CQL event would get triggered from other drivers, so that PMF driver would adjust the system thermal config based on the ACPI inputs. OEMs can control whether or not to enable AMT or CQL via other supported drivers[1] but the actual transition logic resides in the AMD PMF driver. When an AMT event is received the automatic mode transition RAPL algorithm will run. When a CQL event is received an performance "on-lap" mode will be enabled and thermal parameters will be adjusted accordingly.

This feature has 3 modes quiet, balanced, performance The objective of this feature is to track the moving average of system power over the time period specified and switch to the subsequent mode. In order to do this, PMF driver will get the moving average of APU power from PMFW and power threshold, time constants, system config parameters from OEM inputs. System power as read by PMF driver from PMFW is the filtered value over the sampling window. Every sampling window, moving average of system power is computed. At the end of the monitoring window, the moving average is compared against the threshold for mode switch for decision making. With AMD managing the system config limits, any mode switch within auto-mode will result in limits of fPPT/sPPT/STAPM or STT being scaled down. When "auto mode" is enabled, the static slider control remains out of the PMF driver, so the platform_profile registration would not happen in PMF driver. The transition to auto-mode only happens when the APMF fn5 is enabled in BIOS, platform_profile set to "balanced" and a AMT (Auto Mode transition) is received. Reviewed-by:

PMF has a generic interface defined via PMF ACPI fn9 for influencing fan policy during mode switch. PMF ACPI fn9 will normally be invoked when AMDPMF needs to change the fan table index for the EC. When AMDPMF is loaded this function will be invoked to change fan speed. OEM can also choose to report the actual fan table index and fan RPM to PMF through OEM structure. This information will be communicated by PMF driver to customer BIOS. Reviewed-by:

PMF driver can send periodic heartbeat signals to OEM BIOS. When BIOS does not receive the signal after a period of time, it can infer that AMDPMF has hung or failed to load. In this situation, BIOS can fallback to legacy operations. OEM can modify the time interval of the signal or completely disable signals through ACPI Method. Reviewed-by:
