Subject: [PATCH 9/9] virtio: virtio-pci: restrict MIPS support to MMU configuration
Date: Sun, 28 Feb 2021 20:08:36 +0100 [thread overview]
Message-ID: <20210228190836.1451663-9-ahmad@a3f.at> (raw)
In-Reply-To: <20210228190836.1451663-1-ahmad@a3f.at>
MMU-less MIPS doesn't play along nicely with VIRTIO_PCI.
e.g. Reading from a virtio-rng, will return clearly bogus data.
Document this in the Kconfig, so no one else trips over this.
Eventually, this should be fixed..
