These PMU devices are loosely architected to follow the same model as the PMU for ARM cores. Signed-off-by: Tai Nguyen v2: * Use bitmask for event asignned counter mask pmu_dev->cntr_assign_mask * Remove unnecessary spinlocks in perf add/del operations * Remove unnecessary condition checks * Enforce CPU assignment to one CPU for perf operarations * Set the task_ctx_nr to perf_invalid_context for perf driver * Remove irrelevant pt_rregs * Change perf sysfs attributes to be fixed instead of dynamic * Fix checking for an ACPI companion device instead of EFI enable * Add documentation for config/config1 fields format and perf tool example --- Tai Nguyen (4): MAINTAINERS: Add entry for APM X-Gene SoC PMU driver Documentation: Add documentation for APM X-Gene SoC PMU DTS binding perf: xgene: Add APM X-Gene SoC Performance Monitoring Unit driver arm64: dts: apm: Add APM X-Gene SoC PMU DTS entries .../devicetree/bindings/perf/apm-xgene-pmu.txt | 116 ++ Documentation/perf/xgene-pmu.txt | 48 + MAINTAINERS | 7 + arch/arm64/boot/dts/apm/apm-storm.dtsi | 60 + drivers/perf/Kconfig | 7 + drivers/perf/Makefile | 1 + drivers/perf/xgene_pmu.c | 1414 ++++++++++++++++++++ 7 files changed, 1653 insertions(+) create mode 100644 Documentation/devicetree/bindings/perf/apm-xgene-pmu.txt create mode 100644 Documentation/perf/xgene-pmu.txt create mode 100644 drivers/perf/xgene_pmu.c -- 1.9.1
