After the recent cleanup patches, some of the *_check_present() helpers just propagate the result of asus_wmi_dev_is_present(). Replace these with direct asus_wmi_dev_is_present() calls as a further cleanup. Cc: Luke D. Jones <luke@ljones.dev> Signed-off-by:

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:

Add software nodes for the HID sensor collection and the UCM UCSI HID client to the Surface Pro 8. In contrast to the type-cover devices, these devices are directly attached to the SAM controller, without any hub. This enables support for HID-based sensors, including the ones used for automatic screen rotation, on the Surface Pro 8. Signed-off-by:

The driver core supports the ability to handle the creation and removal of device-specific sysfs files in a race-free manner. Take advantage of that by converting this driver to use this by moving the sysfs attributes into a group and assigning the dev_groups pointer to it.

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 driver polls for metrics information from PMFW to understand the system behavior, power consumption etc. This metrics table information will be used the PMF features to tweak the thermal heuristics. The poll duration can also be changed by the user by changing the poll duration time. 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:

SPS (a.k.a. Static Power Slider) gives a feel of Windows performance power slider for the Linux users, where the user selects a certain mode (like "balanced", "low-power" or "performance") and the thermals associated with each selected mode gets applied from the silicon side via the mailboxes defined through PMFW. PMF driver hooks to platform_profile by reading the PMF ACPI fn9 to see if the support is being advertised by ACPI interface. If supported, the PMF driver reacts to platform_profile selection choices made by the user and adjust the system thermal behavior. Reviewed-by:

PMF driver implements the ACPI methods as defined by AMD for PMF Support. The ACPI layer acts as a glue that helps in providing the infrastructure for OEMs customization. OEMs can refer to PMF support documentation to decide on the list of functions to be supported on their specific platform model. AMD mandates that PMF ACPI fn0 and fn1 to be implemented which provides the set of functions, params and the notifications that would be sent to PMF driver so that PMF driver can adapt and react.
