From 56f65ed838e8d73e91d54a8ed984d777c936843c Mon Sep 17 00:00:00 2001 From: Olivier Martin Date: Wed, 11 Dec 2013 16:58:22 +0000 Subject: OvmfPkg: Make the VirtIo devices use the new VIRTIO_DEVICE_PROTOCOL This change replaces the accesses to the PCI bus from the Block, Scsi and Net drivers by the use of the new VIRTIO_DEVICE_PROTOCOL protocol that abstracts the transport layer. It means these drivers can be used on PCI and MMIO transport layer.
