Subject: [PATCH 2/5] perf: arm_spe: Add new event packet bits
Date: Tue, 22 Sep 2020 11:12:22 +0100 [thread overview]
Message-ID: <20200922101225.183554-3-andre.przywara@arm.com> (raw)
In-Reply-To: <20200922101225.183554-1-andre.przywara@arm.com>
The ARMv8.3-SPE extension adds some new bits to the event packet
fields.
Handle bits 11 (alignment), 17 and 18 (SVE predication) when decoding
the SPE buffer content.
