5a67c0d1 - platform/x86/amd: amd_3d_vcache: Add AMD 3D V-Cache optimizer driver

Tue, 12 Nov 2024 17:03:06 +0000

platform/x86/amd: amd_3d_vcache: Add AMD 3D V-Cache optimizer driverAMD X3D processors, also known as AMD 3D V-Cache, feature dual CoreComplex Dies (CCDs) and enlarged L3 cache, enabling dynamic modeswitching between Frequency and Cache modes. To optimize performance,implement the AMD 3D V-Cache Optimizer, which allows selecting either:Frequency mode: cores within the faster CCD are prioritized beforethose in the slower CCD.Cache mode: cores within the larger L3 CCD are prioritized beforethose in the smaller L3 CCD.Co-developed-by: Perry Yuan Signed-off-by: Perry Yuan Co-developed-by: Mario Limonciello Signed-off-by: Mario Limonciello Reviewed-by: Shyam Sundar S K Reviewed-by: Armin Wolf Signed-off-by: Basavaraj Natikar Link: https://lore.kernel.org/r/20241112170307.3745777-2-Basavaraj.Natikar@amd.comReviewed-by: Ilpo Järvinen Signed-off-by: Ilpo Järvinen List of files: /linux-6.15/drivers/platform/x86/amd/Kconfig

58e82a62 - platform/x86/amd: Add support for AMD ACPI based Wifi band RFI mitigation feature

Mon, 11 Dec 2023 10:06:23 +0000

platform/x86/amd: Add support for AMD ACPI based Wifi band RFI mitigation featureDue to electrical and mechanical constraints in certain platform designsthere may be likely interference of relatively high-powered harmonics ofthe (G-)DDR memory clocks with local radio module frequency bands usedby Wifi 6/6e/7.To mitigate this, AMD has introduced a mechanism that devices can use tonotify active use of particular frequencies so that other devices can makerelative internal adjustments as necessary to avoid this resonance.Co-developed-by: Evan Quan Signed-off-by: Evan Quan Signed-off-by: Ma Jun Reviewed-by: Mario Limonciello Reviewed-by: Hans de Goede Signed-off-by: Hans de Goede List of files: /linux-6.15/drivers/platform/x86/amd/Kconfig

Sun, 09 Apr 2023 18:53:45 +0000

platform/x86/amd: pmc: Utilize SMN index 0 for driver probeThe current SMN index used for the driver probe seems to be meantfor the BIOS pair and there are potential concurrency problems that canoccur with an inopportune SMI.It is been advised to use SMN_INDEX_0 instead of SMN_INDEX_2, which iswhat amd_nb.c provides and this function has protections to ensure thatonly one caller can use it at a time.Fixes: 156ec4731cb2 ("platform/x86: amd-pmc: Add AMD platform support for S2Idle")Co-developed-by: Sanket Goswami Signed-off-by: Sanket Goswami Signed-off-by: Shyam Sundar S K Link: https://lore.kernel.org/r/20230409185348.556161-6-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/Kconfig

platform/x86: Move AMD platform drivers to separate directoryCurrently, AMD supported platform drivers are grouped under generic "x86"folder structure. Move the current drivers (amd-pmc and amd_hsmp) to aseparate directory. This would also mean the newer driver submissions topdx86 subsystem in the future will also land in AMD specific directory.Reviewed-by: Naveen Krishna Chatradhi Tested-by: Suma Hegde Signed-off-by: Shyam Sundar S K Link: https://lore.kernel.org/r/20220608193212.2827257-1-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/Kconfig
