Compare with v2: - Checks return value of strdup() - Change BPF map setting syntax to 'maps:[mapname].[event:value]=value' For example: 'maps:mapname.value[1,3...5]=10' Test cases in each commit message are also changed correspondingly. (Thanks to Namhyung Kim) 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 most of the patches I list commands for testing them, both normal case and error case.
