Hello, This is a collection of small fixes for perf stat bpf counters (bperf). The bperf framework maintains perf_attr_map in the BPF fs to share the same event as much as possible. But the size was limited to 16 and perf stat with -ddd option would create more than 16 events and fails. Also cgroup events with --for-each-cgroup had some other problems when dealing with unsupported events and duplicate cgroups. The code is available at 'perf/stat-bpf-fix-v1' branch in git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git Thanks, Namhyung Namhyung Kim (4): perf bpf_counter: Add more error messages for bperf perf bpf_counter: Increase perf_attr_map entries to 32 perf bpf_counter: Handle unsupported cgroup events perf stat: Do not use the same cgroup more than once tools/perf/util/bpf_counter.c | 11 ++++++++--- tools/perf/util/bpf_counter_cgroup.c | 14 +++----------- tools/perf/util/cgroup.c | 23 ++++++++++++++++++----- 3 files changed, 29 insertions(+), 19 deletions(-) base-commit: d8d85ce86dc82de4f88b821a78f533b9d5b22a45 -- 2.39.0.314.g84b9a713c41-goog
