Subject: [PATCH v4 10/14] perf tools: add branch-brs as a new event
Date: Fri, 10 Dec 2021 13:02:25 -0800	[thread overview]
Message-ID: <20211210210229.2991238-11-eranian@google.com> (raw)
In-Reply-To: <20211210210229.2991238-1-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.
