Subject: [PATCH] perf test: Fix record test on KVM guests
Date: Tue, 22 Nov 2022 09:31:21 +0100 [thread overview]
Message-ID: <20221122083121.6012-1-mpetlan@redhat.com> (raw)
Using precise flag with br_inst_retired.near_call causes the test fail
on KVM guests, even when the guests have PMU forwarding enabled and the
event itself is supported.
Remove the precise flag in order to make the test work on KVM guests.
