Subject: [PATCH v2 1/4] perf event: Add simd_flags field to perf_sample
Date: Mon, 20 Mar 2023 15:15:05 +0000 [thread overview]
Message-ID: <20230320151509.1137462-2-james.clark@arm.com> (raw)
In-Reply-To: <20230320151509.1137462-1-james.clark@arm.com>
From: German Gomez <german.gomez@arm.com>
Add new field to the struct perf_sample to store flags related to SIMD
ops.
It will be used to store SIMD information from SVE and NEON when
profiling using ARM SPE.
