Subject: [PATCH RFC v1 2/3] perf: Add perf_event_attr::config3
Date: Thu, 25 Aug 2022 13:08:01 -0500 [thread overview]
Message-ID: <20220825-arm-spe-v8-7-v1-2-c75b8d92e692@kernel.org> (raw)
In-Reply-To: <20220825-arm-spe-v8-7-v1-0-c75b8d92e692@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.
