Subject: [PATCH v4 8/8] ARM: mach-virt: Select PMUv3 driver by default
Date: Fri, 17 Mar 2023 15:50:27 -0400 [thread overview]
Message-ID: <20230317195027.3746949-9-zalbassam@google.com> (raw)
In-Reply-To: <20230317195027.3746949-1-zalbassam@google.com>
From: Marc Zyngier <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.
