Subject: [PATCH v5 1/2] perf tools: Sync perf_event_attr::config3 addition
Date: Fri, 17 Feb 2023 16:32:10 -0600 [thread overview]
Message-ID: <20220914-arm-perf-tool-spe1-2-v2-v5-1-2cf5210b2f77@kernel.org> (raw)
In-Reply-To: <20220914-arm-perf-tool-spe1-2-v2-v5-0-2cf5210b2f77@kernel.org>
Arm SPEv1.2 adds another 64-bits of event filtering control. As the
existing perf_event_attr::configN fields are all used up for SPE PMU, an
additional field is needed. Add a new 'config3' field.
Signed-off-by: Rob Herring <robh@kernel.org>
