Subject: [PATCH v9 15/16] perf arm_spe: Decode memory tagging properties
Date: Thu, 19 Nov 2020 23:24:40 +0800 [thread overview]
Message-ID: <20201119152441.6972-16-leo.yan@linaro.org> (raw)
In-Reply-To: <20201119152441.6972-1-leo.yan@linaro.org>
From: Andre Przywara <andre.przywara@arm.com>
When SPE records a physical address, it can additionally tag the event
with information from the Memory Tagging architecture extension.
Decode the two additional fields in the SPE event payload.
[leoy: Refined patch to use predefined macros]
