Subject: [PATCH v2 06/20] arc: perf/core: advertise PMU exclusion capability
Date: Mon, 26 Nov 2018 11:12:22 +0000 [thread overview]
Message-ID: <1543230756-15319-7-git-send-email-andrew.murray@arm.com> (raw)
In-Reply-To: <1543230756-15319-1-git-send-email-andrew.murray@arm.com>
The ARC PMU has the capability to exclude events based on
context. Let's advertise that we support the
PERF_PMU_CAP_EXCLUDE capability to ensure that perf doesn't
prevent us from handling events where any exclusion flags are
set.
