Date: Mon, 28 Sep 2026 10:20:40 +0000 [thread overview]
Message-ID: <20260928102041.491221F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260928-perf_cs_etm_callchain_test_add_kcore-v2-1-24fff6fab009@arm.com>
> The CoreSight callchain test traces both userspace and kernel execution
> and checks the callchain across a syscall.
>
> Add --kcore to perf record to save the running kernel image alongside
> the trace data so perf script can use it to decode the kernel trace.
> If kcore is not available, the test will be skipped.
>
> Add a Fixes tag so the change can be backported to stable kernels and
> improve the test reliability.

> Fixes: ca0e19074bd6 ("perf test: Add Arm CoreSight callchain test")
