Subject: [PATCH v2 13/25] perf arm_spe: Report associated info for SVE / SME operations
Date: Fri, 17 Oct 2025 11:05:02 +0100 [thread overview]
Message-ID: <20251017-perf_support_arm_spev1-3-v2-13-2d41e4746e1b@arm.com> (raw)
In-Reply-To: <20251017-perf_support_arm_spev1-3-v2-0-2d41e4746e1b@arm.com>
SVE / SME operations can be predicated or Gather load / scatter store,
save the relevant info into record.
