2 # Performance Monitor Drivers
5 menu "Performance monitor support"
9 tristate "ARM CCI PMU driver"
10 depends on (ARM && CPU_V7) || ARM64
13 Support for PMU events monitoring on the ARM CCI (Cache Coherent
14 Interconnect) family of products.
16 If compiled as a module, it will be called arm-cci.
19 bool "support CCI-400"
21 depends on ARM_CCI_PMU
22 select ARM_CCI400_COMMON
24 CCI-400 provides 4 independent event counters counting events related
25 to the connected slave/master interfaces, plus a cycle counter.
28 bool "support CCI-500/CCI-550"
30 depends on ARM_CCI_PMU
32 CCI-500/CCI-550 both provide 8 independent event counters, which can
33 count events pertaining to the slave/master interfaces as well as the
34 internal events to the CCI.
37 tristate "ARM CCN driver support"
38 depends on ARM || ARM64
40 PMU (perf) driver supporting the ARM CCN (Cache Coherent Network)
44 depends on ARM || ARM64
45 bool "ARM PMU framework"
48 Say y if you want to use CPU performance monitors on ARM-based
52 depends on ARM_PMU && ACPI
56 tristate "ARM DynamIQ Shared Unit (DSU) PMU"
59 Provides support for performance monitor unit in ARM DynamIQ Shared
60 Unit (DSU). The DSU integrates one or more cores with an L3 memory
61 system, control logic. The PMU allows counting various events related
65 bool "HiSilicon SoC PMU"
66 depends on ARM64 && ACPI
68 Support for HiSilicon SoC uncore performance monitoring
69 unit (PMU), such as: L3C, HHA and DDRC.
72 bool "Qualcomm Technologies L2-cache PMU"
73 depends on ARCH_QCOM && ARM64 && ACPI
75 Provides support for the L2 cache performance monitor unit (PMU)
76 in Qualcomm Technologies processors.
77 Adds the L2 cache PMU into the perf events subsystem for
78 monitoring L2 cache events.
81 bool "Qualcomm Technologies L3-cache PMU"
82 depends on ARCH_QCOM && ARM64 && ACPI
83 select QCOM_IRQ_COMBINER
85 Provides support for the L3 cache performance monitor unit (PMU)
86 in Qualcomm Technologies processors.
87 Adds the L3 cache PMU into the perf events subsystem for
88 monitoring L3 cache events.
92 bool "APM X-Gene SoC PMU"
95 Say y if you want to use APM X-Gene SoC performance monitors.
98 tristate "Enable support for the ARMv8.2 Statistical Profiling Extension"
99 depends on PERF_EVENTS && ARM64
101 Enable perf support for the ARMv8.2 Statistical Profiling
102 Extension, which provides periodic sampling of operations in
103 the CPU pipeline and reports this via the perf AUX interface.
