OvmfPkg: Virtio10Dxe: non-transitional driver for virtio-1.0 PCI devices This driver implements the VIRTIO_DEVICE_PROTOCOL for non-transitional PCI devices, based on the virtio-1.0 specification (csprd05). Non-transitional means that it only binds QEMU's virtio-xxx-pci devices that receive the ",disable-legacy=on,disable-modern=off" properties on the QEMU command line. These devices have distinct PCI Device IDs from those that are bound by VirtioPciDeviceDxe. The central abstraction of this driver is the VIRTIO_1_0_CONFIG type. It is practically a "fat pointer" to a register block. The pointed-to register block - may or may not exist (the latter being mostly useful for virtio-1.0 devices that have no device-specific registers), - lives in one of the device's BARs, - lives in an IO or MMIO BAR, - lives at an offset relative to the BAR start, - has its size also maintained. Such VIRTIO_1_0_CONFIG "fat pointers" (i.e., the locations of the register blocks) are parsed from vendor capabilities that reside in the device's standard PCI capabilities list (in PCI config space).

OvmfPkg/Virtio10Dxe: convert to PciCapLib Replace the manual capability list parsing in OvmfPkg/Virtio10Dxe with PciCapLib and PciCapPciIoLib API calls. The VIRTIO_PCI_CAP_LINK structure type is now superfluous. (Well, it always has been; we should have used EFI_PCI_CAPABILITY_HDR.) Also, EFI_PCI_CAPABILITY_VENDOR_HDR is now included at the front of VIRTIO_PCI_CAP. No driver other than Virtio10Dxe relies on VIRTIO_PCI_CAP.
