^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 212) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 213) The libperf library provides an API to access the linux kernel perf
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 214) events subsystem.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 215)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 216) Following objects are key to the libperf interface:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 217)

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 219)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 220) struct perf_cpu_map:: Provides a CPU list abstraction.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 221)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 222) struct perf_thread_map:: Provides a thread list abstraction.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 223)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 224) struct perf_evsel:: Provides an abstraction for single a perf event.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 225)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 226) struct perf_evlist:: Gathers several struct perf_evsel object and performs functions on all of them.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 227)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 228) struct perf_mmap:: Provides an abstraction for accessing perf ring buffer.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 229)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 230) The exported API functions bind these objects together.
