Subject: [PATCH v2 02/25] perf arm_spe: Unify operation naming
Date: Fri, 17 Oct 2025 11:04:51 +0100 [thread overview]
Message-ID: <20251017-perf_support_arm_spev1-3-v2-2-2d41e4746e1b@arm.com> (raw)
In-Reply-To: <20251017-perf_support_arm_spev1-3-v2-0-2d41e4746e1b@arm.com>
Rename extended subclass and SVE/SME register access subclass, so that
the naming can be consistent cross all sub classes.
Add an log "SVE-SME-REG" for the SVE/SME register access, this is easier
for parsing.
