Subject: [PATCH v5 20/21] perf arm_spe: Decode memory tagging properties
Date: Thu, 29 Oct 2020 15:19:26 +0800 [thread overview]
Message-ID: <20201029071927.9308-21-leo.yan@linaro.org> (raw)
In-Reply-To: <20201029071927.9308-1-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]
