perf: arm_cspmu: ampere_cspmu: Add support for Ampere SoC PMUAmpere SoC PMU follows CoreSight PMU architecture. It uses implementationspecific registers to filter events rather than PMEVFILTnR registers.Signed-off-by: Ilkka Koskinen Link: https://lore.kernel.org/r/20230913233941.9814-5-ilkka@os.amperecomputing.com[will: Include linux/io.h in ampere_cspmu.c for writel()]Signed-off-by: Will Deacon List of files: /linux-6.15/drivers/perf/arm_cspmu/Kconfig

bfc653aa - perf: arm_cspmu: Separate Arm and vendor module

Mon, 21 Aug 2023 23:16:08 +0000

perf: arm_cspmu: Separate Arm and vendor moduleArm Coresight PMU driver consists of main standard code andvendor backend code. Both are currently built as a single module.This patch adds vendor registration API to separate the two tokeep things modular. The main driver requests each known backendmodule during initialization and defer device binding process.The backend module then registers an init callback to the maindriver and continue the device driver binding process.Signed-off-by: Besar Wicaksono Reviewed-by: Suzuki K Poulose Reviewed-and-tested-by: Ilkka Koskinen Link: https://lore.kernel.org/r/20230821231608.50911-1-bwicaksono@nvidia.comSigned-off-by: Will Deacon List of files: /linux-6.15/drivers/perf/arm_cspmu/Kconfig

f9bd34e3 - perf/arm_cspmu: Clean up ACPI dependency

perf/arm_cspmu: Clean up ACPI dependencyBuild-wise, the ACPI dependency consists of only a couple of thingswhich could probably stand being factored out into ACPI helpers anyway.However for the immediate concern of working towards Devicetree supporthere, it's easy enough to make a few tweaks to contain the affected codelocally, such that we can relax the Kconfig dependency.Reviewed-and-Tested-by: Suzuki K Poulose Reviewed-by: Ilkka Koskinen Signed-off-by: Robin Murphy Link: https://lore.kernel.org/r/9d126711c7498b199b3e6f5cf48ca60ffb9df54c.1685983270.git.robin.murphy@arm.comSigned-off-by: Will Deacon List of files: /linux-6.15/drivers/perf/arm_cspmu/Kconfig

e37dfd65 - perf: arm_cspmu: Add support for ARM CoreSight PMU driver

Fri, 11 Nov 2022 22:23:28 +0000

perf: arm_cspmu: Add support for ARM CoreSight PMU driverAdd support for ARM CoreSight PMU driver framework and interfaces.The driver provides generic implementation to operate uncore PMU basedon ARM CoreSight PMU architecture. The driver also provides interfaceto get vendor/implementation specific information, for example eventattributes and formating.The specification used in this implementation can be found below: * ACPI Arm Performance Monitoring Unit table: https://developer.arm.com/documentation/den0117/latest * ARM Coresight PMU architecture: https://developer.arm.com/documentation/ihi0091/latestReviewed-by: Suzuki K Poulose Signed-off-by: Besar Wicaksono Link: https://lore.kernel.org/r/20221111222330.48602-2-bwicaksono@nvidia.comSigned-off-by: Will Deacon List of files: /linux-6.15/drivers/perf/arm_cspmu/Kconfig
