2 # Performance Monitor Drivers
5 menu "Performance monitor support"
13 bool "ARM CCI400 PMU support"
14 depends on (ARM && CPU_V7) || ARM64
15 select ARM_CCI400_COMMON
18 Support for PMU events monitoring on the ARM CCI-400 (cache coherent
19 interconnect). CCI-400 supports counting events related to the
20 connected slave/master interfaces.
23 bool "ARM CCI-500/CCI-550 PMU support"
24 depends on (ARM && CPU_V7) || ARM64
27 Support for PMU events monitoring on the ARM CCI-500/CCI-550 cache
28 coherent interconnects. Both of them provide 8 independent event counters,
29 which can count events pertaining to the slave/master interfaces as well
30 as the internal events to the CCI.
35 tristate "ARM CCN driver support"
36 depends on ARM || ARM64
38 PMU (perf) driver supporting the ARM CCN (Cache Coherent Network)
42 depends on ARM || ARM64
43 bool "ARM PMU framework"
46 Say y if you want to use CPU performance monitors on ARM-based
50 depends on ARM_PMU && ACPI
54 tristate "ARM DynamIQ Shared Unit (DSU) PMU"
57 Provides support for performance monitor unit in ARM DynamIQ Shared
58 Unit (DSU). The DSU integrates one or more cores with an L3 memory
59 system, control logic. The PMU allows counting various events related
63 bool "HiSilicon SoC PMU"
64 depends on ARM64 && ACPI
66 Support for HiSilicon SoC uncore performance monitoring
67 unit (PMU), such as: L3C, HHA and DDRC.
70 bool "Qualcomm Technologies L2-cache PMU"
71 depends on ARCH_QCOM && ARM64 && ACPI
73 Provides support for the L2 cache performance monitor unit (PMU)
74 in Qualcomm Technologies processors.
75 Adds the L2 cache PMU into the perf events subsystem for
76 monitoring L2 cache events.
79 bool "Qualcomm Technologies L3-cache PMU"
80 depends on ARCH_QCOM && ARM64 && ACPI
81 select QCOM_IRQ_COMBINER
83 Provides support for the L3 cache performance monitor unit (PMU)
84 in Qualcomm Technologies processors.
85 Adds the L3 cache PMU into the perf events subsystem for
86 monitoring L3 cache events.
90 bool "APM X-Gene SoC PMU"
93 Say y if you want to use APM X-Gene SoC performance monitors.
96 tristate "Enable support for the ARMv8.2 Statistical Profiling Extension"
97 depends on PERF_EVENTS && ARM64
99 Enable perf support for the ARMv8.2 Statistical Profiling
100 Extension, which provides periodic sampling of operations in
101 the CPU pipeline and reports this via the perf AUX interface.
