Subject: [PATCH v2 13/14] perf arm_spe: Decode memory tagging properties
Date: Tue, 29 Sep 2020 14:39:16 +0100 [thread overview]
Message-ID: <20200929133917.9224-14-leo.yan@linaro.org> (raw)
In-Reply-To: <20200929133917.9224-1-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]
