Subject: [PATCH v5 15/21] perf arm-spe: Refactor event type handling
Date: Thu, 29 Oct 2020 15:19:21 +0800	[thread overview]
Message-ID: <20201029071927.9308-16-leo.yan@linaro.org> (raw)
In-Reply-To: <20201029071927.9308-1-leo.yan@linaro.org>

Move the enums of event types to arm-spe-pkt-decoder.h, thus function
arm_spe_pkt_desc() can them for bitmasks.

Suggested-by: Andre Przywara <andre.przywara@arm.com>
