cfba129a - platform/x86: amd: Use -y instead of -objs in Makefiles

Tue, 18 Feb 2025 19:41:09 +0000

platform/x86: amd: Use *-y instead of *-objs in MakefilesThe `objs` suffix is reserved for user-space tools. Use the `y` suffixinstead, which is usually used for kernel drivers.While at it, fix alignment in AMD PMC and PMF Makefiles.Suggested-by: Andy Shevchenko Signed-off-by: Kurt Borja Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20250218194113.26589-3-kuurtb@gmail.comReviewed-by: Ilpo Järvinen Signed-off-by: Ilpo Järvinen List of files: /linux-6.15/drivers/platform/x86/amd/pmf/Makefile

1738061c - platform/x86/amd/pmf: Add support for CnQF

Thu, 22 Sep 2022 13:12:00 +0000

platform/x86/amd/pmf: Add support for CnQFCnQF (a.k.a Cool and Quiet Framework) extends the static slider concept.PMF dynamically manages system power limits and fan policy based on systempower trends which is representative of workload trend.Static slider and CnQF controls are mutually exclusive for system powerbudget adjustments. CnQF supports configurable number of modes which canbe unique for AC and DC. Every mode is representative of a system statecharacterized by unique steady state and boost behavior.OEMs can configure the different modes/system states and how thetransition to a mode happens. Whether to have CnQF manage system powerbudget dynamically in AC or DC or both is also configurable. Mode changesdue to CnQF don't result in slider position change.The default OEM values are obtained after evaluating the PMF ACPI functionidx 11 & 12 for AC and DC respectively. Whether to turn ON/OFF by defaultis guided by a "flag" passed by the OEM BIOS.Signed-off-by: Shyam Sundar S K Link: https://lore.kernel.org/r/20220922131202.56529-2-Shyam-sundar.S-k@amd.comReviewed-by: Hans de Goede Signed-off-by: Hans de Goede List of files: /linux-6.15/drivers/platform/x86/amd/pmf/Makefile

3f5571d9 - platform/x86/amd/pmf: Add support for Auto mode feature

Tue, 02 Aug 2022 15:11:46 +0000

platform/x86/amd/pmf: Add support for Auto mode featureThis feature has 3 modes quiet, balanced, performanceThe objective of this feature is to track the moving average of systempower 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 powerfrom PMFW and power threshold, time constants, system config parametersfrom OEM inputs.System power as read by PMF driver from PMFW is the filtered value overthe sampling window. Every sampling window, moving average of system poweris computed. At the end of the monitoring window, the moving average iscompared against the threshold for mode switch for decision making.With AMD managing the system config limits, any mode switch withinauto-mode will result in limits of fPPT/sPPT/STAPM or STT being scaleddown.When "auto mode" is enabled, the static slider control remains out ofthe PMF driver, so the platform_profile registration would nothappen in PMF driver.The transition to auto-mode only happens when the APMF fn5 is enabledin BIOS, platform_profile set to "balanced" and a AMT(Auto Mode transition) is received.Reviewed-by: Hans de Goede Signed-off-by: Shyam Sundar S K Link: https://lore.kernel.org/r/20220802151149.2123699-9-Shyam-sundar.S-k@amd.comSigned-off-by: Hans de Goede List of files: /linux-6.15/drivers/platform/x86/amd/pmf/Makefile

platform/x86/amd/pmf: Add support SPS PMF featureSPS (a.k.a. Static Power Slider) gives a feel of Windows performancepower slider for the Linux users, where the user selects a certainmode (like "balanced", "low-power" or "performance") and the thermalsassociated with each selected mode gets applied from the siliconside via the mailboxes defined through PMFW.PMF driver hooks to platform_profile by reading the PMF ACPI fn9 tosee if the support is being advertised by ACPI interface.If supported, the PMF driver reacts to platform_profile selection choicesmade by the user and adjust the system thermal behavior.Reviewed-by: Hans de Goede Signed-off-by: Shyam Sundar S K Link: https://lore.kernel.org/r/20220802151149.2123699-4-Shyam-sundar.S-k@amd.comSigned-off-by: Hans de Goede List of files: /linux-6.15/drivers/platform/x86/amd/pmf/Makefile

platform/x86/amd/pmf: Add support for PMF APCI layerPMF driver implements the ACPI methods as defined by AMD for PMF Support.The ACPI layer acts as a glue that helps in providing the infrastructurefor OEMs customization.OEMs can refer to PMF support documentation to decide on the list offunctions to be supported on their specific platform model.AMD mandates that PMF ACPI fn0 and fn1 to be implemented whichprovides the set of functions, params and the notifications thatwould be sent to PMF driver so that PMF driver can adapt andreact.Signed-off-by: Shyam Sundar S K Link: https://lore.kernel.org/r/20220802151149.2123699-3-Shyam-sundar.S-k@amd.comReviewed-by: Hans de Goede Signed-off-by: Hans de Goede List of files: /linux-6.15/drivers/platform/x86/amd/pmf/Makefile
