| perf (sometimes "Perf Events" or perf tools, originally |
| "Performance Counters for Linux") - is a performance |
| analyzing tool in Linux, available from kernel version |
| 2.6.31. User-space controlling utility, called 'perf' has |
| git-like interface with subcommands. It is capable of |
| statistical profiling of entire system (both kernel and user |
| code), single CPU or severals threads. |
| |
| This will build and install the userspace 'perf' |
| command. |
| |
| Your kernel must have CONFIG_PERF_EVENTS enabled to use perf |
| profiling. Buildroot automatically enables this in the kernel |
| configuration. |

| These tracers allow performing latency analysis, for which the |
| rtla tool provides wrapper commands to visualize and extract |
| latency traces and reports. |
| |
| rtla includes three tracers, which have been introduced in |
| different kernel versions: |
| - Linux 5.19 introduced the osnoise and timerlat tracers, |
| - Linux 6.3 introduced the hwnoise tracer |
| |
| osnoise and timerlat are always installed, while hwnoise is |
| installed if your kernel is recent enough. |
| |
| Note: rtla in kernels before 5.19 had additional dependencies, |
| not available in Buildroot, so only rtla in kernels 5.19 |
| onwards is actually supported in Buildroot. |
