Subject: [PATCH] misc: vop: set VIRTIO_F_ACCESS_PLATFORM for vop driver
Date: Tue, 29 Sep 2020 16:49:44 +0800 [thread overview]
Message-ID: <20200929084944.24146-1-sherry.sun@nxp.com> (raw)
Set VIRTIO_F_ACCESS_PLATFORM feature for vop driver, as the DMA mapping
details shouldn't decide on the virtio implementation, but the host PCIe
implementation.
