This patch set is based on perf/core. This patch set improves perf's BPF support:
- Support filling BPF array with values Users are allowed to pass something to BPF program through command line without changing the program itself. - Support filling BPF event array with events BPF program can read PMU counters through BPF's perf_event_read() helper. - Support bpf_output_event() helper BPF program can issue perf event to perf.data. In this patch set: Patch 1/16 - 2/16 are two small bugfix related to building; Patch 3/16 - 13/16 add array filling support. In this 11 patches: Patch 3/16 - 6/16 are preparation; Patch 7/16 - 9/16 enables perf cmdline syntax to (basic) support array filling Patch 10/16 - 11/16 enables setting perf events to BPF event array Patch 12/16 - 13/16 enables setting different slots in an array with different values Patch 14/16 - 16/16 support bpf_output_event() helper. In most of the patches I list commands for testing them, both normal case and error case.
