Changelog from v3:
------------------
- Fixed 'write size' in VIRTIO_DEVICE_WRITE comment
- Made all the functions of the protocol return EFI_STATUS
- Removed 'VIRTIO_GET_GUEST_FEATURES GetGuestFeatures'
- Added a note about the fact VIRTIO_SET_QUEUE_ALIGN is a NOP
- Fixed VIRTIO_GET_DEVICE_STATUS comment
- Added a 'Revision' attribute to the protocol
- Added a longer commit message to VirtioPciDeviceDxe patch
- Clean comment in VirtioPciDeviceDxe
- Empty the scope of VirtioPciUninit() to mirror VirtioPciInit()
- Updated the comment of VIRTIO_SET_QUEUE_ADDRESS/VIRTIO_GET_QUEUE_ADDRESS
with the required division by 4096
- Added VIRTIO_DEVICE_PROTOCOL.SetPageSize() protocol member
- Removed VirtioWriteDevice() and VirtioReadDevice() from VirtioLib.
Limitation:
-----------
- The ARM Foundation Model does not return a valid Vendor ID. As a
consequence, the MMIO Virtio driver cannot return an error if the
Vendor ID does not match the VirtIo Vendor ID.
Not implemented:
----------------
- [Laszlo] A VIRTIO_GET_QUEUE_SEL member / typedef could have been
appropriate for PCI, but I agree that virtio-mmio allows write-only
here.
- [Laszlo] A VIRTIO_GET_QUEUE_NOTIFY member / typedef could have been
appropriate for PCI, but I agree that virtio-mmio allows write-only
here.
- Did not make the change 'VIRTIO_CFG_WRITE (Device,
VIRTIO_MMIO_OFFSET_QUEUE_PFN, 0);'
that fixes the VirtIo support in Linux
- Did not implement VirtioPciGetDeviceName()
Not changed:
------------
- Endianness: All the architectures supported by the UEFI spec
are in 'little endian' mode.
- Keep the PCI 64bit read/write break down into two 32bit accesses:
The VirtiIo BlockIo driver makes (at least) one non 8-byte aligned
access when trying to access the 'VIRTIO_BLK_CONFIG.Capacity' attribute.
VIRTIO_BLK_CONFIG.Capacity is a 64bit field at the offset 0x0 of the
device specific region. This region starts at the offset 20 (0x14) of
the I/O region when there is no MSI-X capability.
Olivier Martin (11):
OvmfPkg/Virtio.h: Added the macros that define the Device Specific
Configuration Offset
