Subject: Re: [PATCH v1 2/4] perf off-cpu: Write the sample ID for PERF_SAMPLE_ID
Date: Tue, 27 Oct 2026 17:12:54 +0000 [thread overview]
Message-ID: <sashiko-outbox-186976@kernel.org> (raw)
In-Reply-To: <20261027170415.2815859-2-irogers@google.com>
> OFFCPU_SAMPLE_TYPES allows PERF_SAMPLE_ID, and the sample ID is
> computed, but off_cpu_write() only wrote it for PERF_SAMPLE_IDENTIFIER.
> When PERF_SAMPLE_ID was set the synthesized samples were one u64 short,
> so the remaining fields were misparsed. Write the ID after the time as
> the sample format requires.

> Fixes: edc41a1099c2 ("perf record: Enable off-cpu analysis with BPF")
> Signed-off-by: Ian Rogers <irogers@google.com>
