Subject: [PATCH v3 10/13] perf tools: add branch-brs as a new event
Date: Tue, 30 Nov 2021 17:02:14 -0800	[thread overview]
Message-ID: <20211201010217.886919-11-eranian@google.com> (raw)
In-Reply-To: <20211201010217.886919-1-eranian@google.com>

Although branch-brs is specific to AMD Zen3, we provide it in the list of
events recognized by perf as a convenience. It allows: $ perf stat -e
branch-brs $ perf list

and enable some test suite to pass.
