Subject: [PATCH v2 19/19] perf tests: Mark the shell tests not mapping perf ring buffers
Date: Tue, 13 Oct 2026 17:14:14 -0300 [thread overview]
Message-ID: <20261013201415.36428-20-acme@kernel.org> (raw)
In-Reply-To: <20261013201415.36428-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Shell tests run perf, that maps ring buffers, so they take a turn using
the per user budget in kernel.perf_event_mlock_kb by default, see the
previous changes; the ones that don't map them, like the ones running
just 'perf stat', say " (no_mlock)" in their description line and thus
keep running in parallel with the ones taking turns.
The 'perf sched stats' tests are among them, they synthesize the samples
from /proc/schedstat without mapping a ring buffer, and the tests already
marked " (exclusive)" don't need it, exclusive implies every other
requisite and keeps them running alone.
