Subject[PATCH v5 0/5] perf util: bpf perf improvements
Date
This patches set improves bpf_perf (perf-stat --bpf-counter) by
1) exposing key definitions to a libperf header;
2) adding compatibility check for perf_attr_map;
3) introducing config stat.bpf-counter-events.
4) introducing 'b' modify to event parser.
5) add bpf_counter_ops->disable()

Changes v4 => v5:
1. Add bpf_counter_ops->disable(). (Namhyung, Jiri)

Changes v3 => v4:
1. Improve the logic that decides when to skip read_affinity_counters().
(Jiri)
2. Clean up a condition in bpf_counters.c:read_counters(). (Jiri)

Changes v2 => v3:
1. Add 'b' modifier. (Jiri)
2. Allow configuring stat.bpf-counter-events with any event name (instead
of limiting to hardware events). (Jiri)

Changes v1 => v2:
1. Separte 2/3 from 1/3. (Jiri)
2. Rename bperf.h to bpf_perf.h. (Jiri)
3. Other small fixes/optimizations. (Jiri)

Song Liu (5):
perf util: move bpf_perf definitions to a libperf header
perf bpf: check perf_attr_map is compatible with the perf binary
perf-stat: introduce config stat.bpf-counter-events
perf-stat: introduce ':b' modifier
perf-stat: introduce bpf_counter_ops->disable()
