Subject: [PATCH bpf-next v3 0/3] bpftool: Improve perf counter reporting
Date: Tue, 08 Sep 2026 07:27:09 -0700 [thread overview]
Message-ID: <20260908-bpftool_cyles_per_run-v3-0-60e86f325c35@meta.com> (raw)
Track valid snapshots that have a zero counter value. Scale each per-CPU
counter before aggregation. Report cycles per included program run.
Signed-off-by: Mykyta Yatsenko <yatsenko@meta.com>
---
Changes in v3:
- Keep the JSON value field raw. Add value_scaled and run_cnt_valid.
- Use the same CPU set for all metrics.
- Move snapshot state tracking to a separate patch.
- Link to v2: https://patch.msgid.link/20260902-bpftool_cyles_per_run-v2-1-bc5d14ad0ce9@meta.com
Changes in v2:
- Scale all counters.
- Use an enum for metric indexes.
- Link to v1: https://patch.msgid.link/20260827-bpftool_cyles_per_run-v1-1-77d7bfc3c065@meta.com
