If PMC discovery using pmc_core_ssram_init() was unsuccessful for the Meteor Lake platform, the legacy enumeration method is used. In this case pci device struct for the PMC SSRAM is not available and pmc_core_ssram_get_lpm_reqs() will not work. Add ssram_init flag to indicate if the PMC SSRAM initialization was successful or not. Call pmc_core_ssram_get_lpm_reqs() only if the ssram_init flag is set to true.

Functions like mtl_set_device_d3() and mtl_punit_pmt_init() were added for Meteor Lake. To be able to use them in Arrow Lake and future platforms, move them to core.c. Also, to support different guids, add guid argument in pmc_core_punit_pmt_init() and to support different PCI function numbers, add func arg in pmc_core_ssram_init().

To sideload pmf policy binaries, the Smart PC Solution Builder provides a debugfs file called "update_policy"; that gets created under a new debugfs directory called "pb" and this new directory has to be associated with existing parent directory for PMF driver called "amd_pmf". In the current code structure, amd_pmf_dbgfs_register() is called after amd_pmf_init_features(). This will not help when the Smart PC builder feature has to be assoicated to the parent directory. Hence change the order of amd_pmf_dbgfs_register() and call it before amd_pmf_init_features() so that when the Smart PC init happens, it has the parent debugfs directory to get itself hooked.

PMF Policy binary is a encrypted and signed binary that will be part of the BIOS. PMF driver via the ACPI interface checks the existence of Smart PC bit. If the advertised bit is found, PMF driver walks the acpi namespace to find out the policy binary size and the address which has to be passed to the TA during the TA init sequence. The policy binary is comprised of inputs (or the events) and outputs (or the actions). With the PMF ecosystem, OEMs generate the policy binary (or could be multiple binaries) that contains a supported set of inputs and outputs which could be specifically carved out for each usage segment (or for each user also) that could influence the system behavior either by enriching the user experience or/and boost/throttle power limits. Once the TA init command succeeds, the PMF driver sends the changing events in the current environment to the TA for a constant sampling frequency time (the event here could be a lid close or open) and if the policy binary has corresponding action built within it, the TA sends the action for it in the subsequent enact command. If the inputs sent to the TA has no output defined in the policy binary generated by OEMs, there will be no action to be performed by the PMF driver. Example policies: 1) if slider is performance ; set the SPL to 40W Here PMF driver registers with the platform profile interface and when the slider position is changed, PMF driver lets the TA know about this. TA sends back an action to update the Sustained Power Limit (SPL). PMF driver updates this limit via the PMFW mailbox. 2) if user_away ; then lock the system Here PMF driver hooks to the AMD SFH driver to know the user presence and send the inputs to TA and if the condition is met, the TA sends the action of locking the system. PMF driver generates a uevent and based on the udev rule in the userland the system gets locked with systemctl. The intent here is to provide the OEM's to make a policy to lock the system when the user is away ; but the userland can make a choice to ignore it. The OEMs will have an utility to create numerous such policies and the policies shall be reviewed by AMD before signing and encrypting them. Policies are shared between operating systems to have seemless user experience. Since all this action has to happen via the "amdtee" driver, currently there is no caller for it in the kernel which can load the amdtee driver. Without amdtee driver loading onto the system the "tee" calls shall fail from the PMF driver. Hence an explicit MODULE_SOFTDEP has been added to address this.

In the current code, the metrics table information was required only for auto-mode or CnQF at a given time. Hence keeping the return type of amd_pmf_set_dram_addr() as static made sense. But with the addition of Smart PC builder feature, the metrics table information has to be shared by the Smart PC also and this feature resides outside of core.c. To make amd_pmf_set_dram_addr() visible outside of core.c make it as a non-static function and move the allocation of memory for metrics table from amd_pmf_init_metrics_table() to amd_pmf_set_dram_addr() as amd_pmf_set_dram_addr() is the common function to set the DRAM address. Add a suspend handler that can free up the allocated memory for getting the metrics table information.

PMF TA (Trusted Application) loads via the TEE environment into the AMD ASP. PMF-TA supports two commands: 1) Init: Initialize the TA with the PMF Smart PC policy binary and start the policy engine. A policy is a combination of inputs and outputs, where; - the inputs are the changing dynamics of the system like the user behaviour, system heuristics etc. - the outputs, which are the actions to be set on the system which lead to better power management and enhanced user experience. PMF driver acts as a central manager in this case to supply the inputs required to the TA (either by getting the information from the other kernel subsystems or from userland) 2) Enact: Enact the output actions from the TA. The action could be applying a new thermal limit to boost/throttle the power limits or change system behavior.

Due to electrical and mechanical constraints in certain platform designs there may be likely interference of relatively high-powered harmonics of the (G-)DDR memory clocks with local radio module frequency bands used by Wifi 6/6e/7. To mitigate this, AMD has introduced a mechanism that devices can use to notify active use of particular frequencies so that other devices can make relative internal adjustments as necessary to avoid this resonance.
