From mboxrd@z Thu Jan 1 00:00:00 1970 From: andrew.murray@arm.com (Andrew Murray) Date: Mon, 26 Nov 2018 11:12:31 +0000 Subject: [PATCH v2 15/20] s390: perf/events: advertise PMU exclusion capability In-Reply-To: <1543230756-15319-1-git-send-email-andrew.murray@arm.com> References: <1543230756-15319-1-git-send-email-andrew.murray@arm.com> Message-ID: <1543230756-15319-16-git-send-email-andrew.murray@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The s390 cpum_cf and cpum_sf PMUs have 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.
