This patch set is based on perf/core.
Compare with v2:
- Checks return value of strdup()
- Change BPF map setting syntax to
'maps:[mapname].[event:value]<indices>=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.
