Subject: [PATCH v4 2/3] perf tools: Sync perf_event_attr::config3 addition
Date: Tue, 04 Oct 2022 14:12:36 -0500	[thread overview]
Message-ID: <20220914-arm-perf-tool-spe1-2-v2-v4-2-83c098e6212e@kernel.org> (raw)
In-Reply-To: <20220914-arm-perf-tool-spe1-2-v2-v4-0-83c098e6212e@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>

This patch is dependent on the kernel side landing first.
