Subject: [PATCH v2 5/5] hw/arm/virt: Disable highmem devices that don't fit in the PA range
Date: Sun, 3 Oct 2021 17:46:05 +0100 [thread overview]
Message-ID: <20211003164605.3116450-6-maz@kernel.org> (raw)
In-Reply-To: <20211003164605.3116450-1-maz@kernel.org>
Make sure both the highmem PCIe and GICv3 regions are disabled when
they don't fully fit in the PA range.
