Subject: [PATCH v2 16/25] perf arm_spe: Expose SIMD information in other operations
Date: Fri, 17 Oct 2025 11:05:05 +0100 [thread overview]
Message-ID: <20251017-perf_support_arm_spev1-3-v2-16-2d41e4746e1b@arm.com> (raw)
In-Reply-To: <20251017-perf_support_arm_spev1-3-v2-0-2d41e4746e1b@arm.com>
The other operations contain SME data processing, ASE (Advanced SIMD)
and floating-point operations. Expose these info in the records.
