Subject: [PATCH] perf test: update arm64 perf_event_attr tests for --call-graph
Date:   Tue, 25 Jan 2022 10:44:34 +0000
Message-Id: <20220125104435.2737-1-german.gomez@arm.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

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")
