| D | executable_commands_reference.md | 5 ## How simpleperf works
13 exposes all events to userspace via the perf_event_open system call, which is used by simpleperf.
19 1. Given user options, simpleperf enables profiling by making a system call to the kernel.
21 3. After profiling, simpleperf reads counters from the kernel, and reports a counter summary.
24 1. Given user options, simpleperf enables profiling by making a system call to the kernel.
25 2. Simpleperf creates mapped buffers between simpleperf and the kernel.
39 The debug-unwind command: debug/test dwarf based offline unwinding, used for debugging simpleperf.
40 The dump command: dumps content in perf.data, used for debugging simpleperf.

10 2. It is recommended to use the latest simpleperf available in AOSP main, if you are not working
11 on the current main branch. Scripts are in `system/extras/simpleperf/scripts`, binaries are in
12 `system/extras/simpleperf/scripts/bin/android`.
30 # Doing recording with app_profiler.py or simpleperf on device, and generates perf.data on host.
42 ## Start simpleperf from system_server process
45 we can add code starting simpleperf at the point where the situation is detected.
47 1. Disable selinux by `adb shell setenforce 0`. Because selinux only allows simpleperf running
