2 # Performance Monitor Drivers
5 menu "Performance monitor support"
9 depends on ARM || ARM64
10 bool "ARM PMU framework"
13 Say y if you want to use CPU performance monitors on ARM-based
17 depends on ARM_PMU && ACPI
21 tristate "ARM DynamIQ Shared Unit (DSU) PMU"
24 Provides support for performance monitor unit in ARM DynamIQ Shared
25 Unit (DSU). The DSU integrates one or more cores with an L3 memory
26 system, control logic. The PMU allows counting various events related
30 bool "HiSilicon SoC PMU"
31 depends on ARM64 && ACPI
33 Support for HiSilicon SoC uncore performance monitoring
34 unit (PMU), such as: L3C, HHA and DDRC.
37 bool "Qualcomm Technologies L2-cache PMU"
38 depends on ARCH_QCOM && ARM64 && ACPI
40 Provides support for the L2 cache performance monitor unit (PMU)
41 in Qualcomm Technologies processors.
42 Adds the L2 cache PMU into the perf events subsystem for
43 monitoring L2 cache events.
46 bool "Qualcomm Technologies L3-cache PMU"
47 depends on ARCH_QCOM && ARM64 && ACPI
48 select QCOM_IRQ_COMBINER
50 Provides support for the L3 cache performance monitor unit (PMU)
51 in Qualcomm Technologies processors.
52 Adds the L3 cache PMU into the perf events subsystem for
53 monitoring L3 cache events.
57 bool "APM X-Gene SoC PMU"
60 Say y if you want to use APM X-Gene SoC performance monitors.
63 tristate "Enable support for the ARMv8.2 Statistical Profiling Extension"
64 depends on PERF_EVENTS && ARM64
66 Enable perf support for the ARMv8.2 Statistical Profiling
67 Extension, which provides periodic sampling of operations in
68 the CPU pipeline and reports this via the perf AUX interface.
