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!
