[PATCH net-next 0/2] perf, bpf: add support for HW_CACHE and RAW events

[Alexei Starovoitov]

Patch 1: add support for HW_CACHE and RAW perf events to bpf:
- similar to PERF_TYPE_RAW and PERF_TYPE_HARDWARE allow PERF_TYPE_HW_CACHE
  events to be accessed via bpf_perf_event_read()
- similar to PERF_TYPE_HARDWARE and PERF_TYPE_SOFTWARE allow bpf programs
  to attch to PERF_TYPE_HW_CACHE and PERF_TYPE_RAW events as
  BPF_PROG_TYPE_PERF_EVENT program type

Patch 2: add tests for HW_CACHE and RAW events

---
Peter,
please review patch 1. It looks trivial and as far as
we can see nothing else needed. The existing perf+bpf infra
covers it just fine.

Thanks!
