Miller" Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org v3->v4: one more tweak to reject unsupported events at map update time as Peter suggested v2->v3: more refactoring to address Peter's feedback. Now all perf_events are attachable and readable v1->v2: address Peter's feedback. Refactor patch 1 to allow attaching bpf programs to all event types and reading counters from all of them as well patch 2 - more tests patch 3 - address Dave's feedback and document bpf_perf_event_read() and bpf_perf_event_output() properly Alexei Starovoitov (1): perf, bpf: Add BPF support to all perf_event types Teng Qin (2): samples/bpf: add tests for more perf event types bpf: update perf event helper functions documentation include/linux/perf_event.h | 7 +- include/uapi/linux/bpf.h | 11 ++- kernel/bpf/arraymap.c | 28 ++----- kernel/events/core.c | 47 ++++++----- kernel/trace/bpf_trace.c | 21 ++--- samples/bpf/bpf_helpers.h | 3 +- samples/bpf/trace_event_user.c | 73 ++++++++++++++--- samples/bpf/tracex6_kern.c | 28 +++++-- samples/bpf/tracex6_user.c | 180 ++++++++++++++++++++++++++++++++--------- tools/include/uapi/linux/bpf.h | 11 ++- 10 files changed, 290 insertions(+), 119 deletions(-) -- 2.9.3
