Subject: [PATCH v3 5/5] ARM: mach-virt: Select PMUv3 driver by default
Date: Fri, 18 May 2018 15:39:13 +0100	[thread overview]
Message-ID: <20180518143913.26306-6-marc.zyngier@arm.com> (raw)
In-Reply-To: <20180518143913.26306-1-marc.zyngier@arm.com>

Since 32bit guests are not unlikely to run on an ARMv8 host,
let's select the PMUv3 driver, which allows the PMU to be used
on such systems.
