98432eec31803ae8707a9fd593ba64cd2648aa74 - platform/x86/amd/pmf: Add util layer and userspace character device interface

Tue, 09 Jun 2026 10:10:38 +0200

platform/x86/amd/pmf: Add util layer and userspace character device interfaceAdd a util layer to AMD PMF that exposes a minimal userspace interfacevia a character device for metrics monitoring and feature discovery.This creates /dev/amdpmf_interface with basic ioctl support to retrievePMF metrics such as:* Power source and power slider position* Platform type, lid state, and user presence* Skin temperature and ambient light* BIOS input parameters (1-10)* Graphics workload metrics* CPU C-state residency (average and maximum)* Socket power consumption* Auto Mode: Automatic power profile switching based on system activity* Static Power Slider: User-selectable power profiles* Policy Builder (Smart PC): Action based policy management* Dynamic Power Slider AC: Adaptive power profiles when on AC power* Dynamic Power Slider DC: Adaptive power profiles when on batteryThe interface enables smoother integration with userspace tools such asAMD SystemDeck [1], which is widely used for monitoring and controllingpower and thermal behavior on AMD platforms. These tools help designerskeep major components within thermal limits to ensure proper operationand enhance overall system stability and reliability.The feature is gated behind the CONFIG_AMD_PMF_UTIL_SUPPORT Kconfigoption, allowing it to be disabled if not needed. The implementationuses existing PMF infrastructure to populate data from the TA (TrustedApplication) shared memory buffer.Link: https://docs.amd.com/v/u/en-US/68773_0.50 [1]Co-developed-by: Sanket Goswami Signed-off-by: Sanket Goswami Signed-off-by: Shyam Sundar S K Link: https://patch.msgid.link/20260609081044.2416731-2-Shyam-sundar.S-k@amd.comReviewed-by: Ilpo Järvinen Signed-off-by: Ilpo Järvinen List of files: /linux/drivers/platform/x86/amd/pmf/Kconfig

Merge tag 'x86_misc_for_v6.14_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tipPull misc x86 updates from Borislav Petkov: - The first part of a restructuring of AMD's representation of a northbridge which is legacy now, and the creation of the new AMD node concept which represents the Zen architecture of having a collection of I/O devices within an SoC. Those nodes comprise the so-called data fabric on Zen. This has at least one practical advantage of not having to add a PCI ID each time a new data fabric PCI device releases. Eventually, the lot more uniform provider of data fabric functionality amd_node.c will be used by all the drivers which need it - Smaller cleanups* tag 'x86_misc_for_v6.14_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/amd_node: Use defines for SMN register offsets x86/amd_node: Remove dependency on AMD_NB x86/amd_node: Update __amd_smn_rw() error paths x86/amd_nb: Move SMN access code to a new amd_node driver x86/amd_nb, hwmon: (k10temp): Simplify amd_pci_dev_to_node_id() x86/amd_nb: Simplify function 3 search x86/amd_nb: Use topology info to get AMD node count x86/amd_nb: Simplify root device search x86/amd_nb: Simplify function 4 search x86: Start moving AMD node functionality out of AMD_NB x86/amd_nb: Clean up early_is_amd_nb() x86/amd_nb: Restrict init function to AMD-based systems x86/mtrr: Rename mtrr_overwrite_state() to guest_force_mtrr_state() List of files: /linux/drivers/platform/x86/amd/pmf/Kconfig
