* OvmfPkg/VirtioPciDeviceDxe: implement IOMMU-like member functionsBrijesh Singh2017-08-251-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | The patch implements the newly added IOMMU-like member functions by respectively delegating the job to: - VIRTIO_DEVICE_PROTOCOL.AllocateSharedPages () -> MemoryAllocationLib.AllocatePages() - VIRTIO_DEVICE_PROTOCOL.FreeSharedPages () -> MemoryAllocationLib.FreePages () - VIRTIO_DEVICE_PROTOCOL.MapSharedBuffer () -> no-op - VIRTIO_DEVICE_PROTOCOL.UnmapSharedBuffer () -> no-op Suggested-by: Laszlo Ersek <lersek@redhat.com> Cc: Ard Biesheuvel <ard.biesheuvel@linaro.org> Cc: Jordan Justen <jordan.l.justen@intel.com> Cc: Tom Lendacky <thomas.lendacky@amd.com> Cc: Laszlo Ersek <lersek@redhat.com> Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Brijesh Singh <brijesh.singh@amd.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> Regression-tested-by: Laszlo Ersek <lersek@redhat.com>
* OvmfPkg/VirtioPciDeviceDxe: supply missing BUS_MASTER attributeBrijesh Singh2017-08-151-3/+7
| | | | | | | | | | | | | | | | | Virtio devices read and write guest RAM (they don't just decode their IO and/or MMIO BARs), which translates to "bus master".

* OvmfPkg: VIRTIO_DEVICE_PROTOCOL: remove GetQueueAddress() memberLaszlo Ersek2016-04-061-1/+0
| | | | | | | | | | | | | This function was never consumed by drivers, and the current prototype is unsupportable with virtio-1.0. Remove the function from the protocol definition, and drop the current (unused) implementations.

* OvmfPkg/VirtioPciDeviceDxe: Implement VIRTIO_DEVICE_PROTOCOL for VirtIo ↵Olivier Martin2013-12-111-0/+680
Devices over PCI This change implements the VIRTIO_DEVICE_PROTOCOL for the PCI transport layer. The VirtIo device drivers will interact with the PCI-based VirtIo devices through this protocol implementation. Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Olivier Martin <olivier.martin@arm.com> v5: - updated comment block on VirtioPciDeviceRead() - return EFI_UNSUPPORTED instead of failed ASSERT() in VirtioPciSetPageSize() - VirtioPciIoRead(): restore the original requirement that FieldSize equal BufferSize exactly (not only divide it). The looping added in v4 did not match the comment block, and the only place that used it in v4 (ie. VirtioNetGetFeatures()) needs an open-coded loop anyway (will be done in a later part of v5).
