Subject: [PATCH] perf test: update arm64 perf_event_attr tests for --call-graph
Date: Tue, 25 Jan 2022 10:44:34 +0000 [thread overview]
Message-ID: <20220125104435.2737-1-german.gomez@arm.com> (raw)
The struct perf_event_attr is initialised differently in Arm64 when
recording in call-graph fp mode, so update the relevant tests, and add
two extra arm64-only tests.
Fixes: 7248e308a575 ("perf tools: Record ARM64 LR register automatically")
Signed-off-by: German Gomez <german.gomez@arm.com>
