Subject: [PATCH v9 10/16] perf arm-spe: Refactor event type handling
Date: Thu, 19 Nov 2020 23:24:35 +0800 [thread overview]
Message-ID: <20201119152441.6972-11-leo.yan@linaro.org> (raw)
In-Reply-To: <20201119152441.6972-1-leo.yan@linaro.org>
Move the enums of event types to arm-spe-pkt-decoder.h, thus function
arm_spe_pkt_desc_event() can use them for bitmasks.
Suggested-by: Andre Przywara <andre.przywara@arm.com>
