Subject: [PATCH v2 08/14] perf test common: Do not globally disable tracing events in clear_all_probes
Date: Thu, 17 Sep 2026 09:38:56 -0700 [thread overview]
Message-ID: <e2ea8c6dfff43fcaba7e6b1135cfdb6ba65b9bd8.1789662556.git.irogers@google.com> (raw)
In-Reply-To: <cover.1789662556.git.irogers@google.com>
`echo 0 > /sys/kernel/debug/tracing/events/enable` disables tracepoint
events system-wide. When running tests in parallel, this kills active
tracing and recording sessions in concurrent tests (such as perf trace
and perf record).
Remove the global event disable from clear_all_probes().
Assisted-by: Antigravity:gemini-3.1-pro
