I split the main patch up into two parts: first the basic support that gets us just the architected events and second the full support patch that tackles the PMRESR interface. Changes since v2: * Rebased onto v3.14-rc1 * Fixed problems found by fuzzer (bitmap logic, per-cpu accesses) Changes since v1: * Dropped sparse warning patch * Reworked percpu irq support patch to hide double pointers in dispatch func * Expanded on comments explaining Krait raw event syntax * Expanded on DT binding * Added qcom,no-pc-write property instead of using cpuid scheme Stephen Boyd (7): ARM: perf_event: Support percpu irqs for the CPU PMU ARM: perf_event: Assign pdev pointer earlier for CPU PMUs ARM: perf_event: Add basic support for Krait CPU PMUs ARM: perf_event: Add hook for event index clearing ARM: perf_event: Fully support Krait CPU PMU events devicetree: bindings: Document Krait performance monitor units (PMU) ARM: dts: msm: Add krait-pmu to platforms with Krait CPUs Documentation/devicetree/bindings/arm/pmu.txt | 9 +- arch/arm/boot/dts/qcom-msm8960-cdp.dts | 6 + arch/arm/boot/dts/qcom-msm8974.dtsi | 5 + arch/arm/include/asm/pmu.h | 2 + arch/arm/kernel/perf_event.c | 16 +- arch/arm/kernel/perf_event_cpu.c | 103 +++-- arch/arm/kernel/perf_event_v7.c | 559 ++++++++++++++++++++++++++ 7 files changed, 666 insertions(+), 34 deletions(-) -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, hosted by The Linux Foundation
