95 Perf Userspace PMU Hardware Counter Access
100 The perf userspace tool relies on the PMU to monitor events. It offers an
103 Arm64 allows userspace tools to have access to the registers storing the

132 The userspace access is supported in libperf using the perf_evsel__mmap()
138 On heterogeneous systems such as big.LITTLE, userspace PMU counter access can

156 counters. Chained events are not supported in conjunction with userspace counter
158 userspace must treat the upper 32-bits read from the counter as UNKNOWN. The
