OvmfPkg/XenPvBlkDxe: Add BlockFront client. This is the code that will do the actual communication between OVMF and a PV block backend, where the block device lives. The protocol used is describe in the blkif.h header. This implementation originally comes from Mini-OS, a part of the Xen Project. Change in V4: - add file header to BlockFront.h (license, copyright, brief desc) Change in V3: - Improve comment of XenBusReadUint64. - Moving blkif.h to this patch with the necessary #pragma pack(4) applied for Ia32. - Add a note about the license in the commit message - Add "The protocol used is describe in the blkif.h header." in the commit message - Have a mandatory sector-size multiple of 512 or fail to initialize. - use Sector instead of Offset for IO request. with Sector been 512-byte unit. - print something if EventChannelNotify return an error. Change in V2: - trigger CoW is probably not needed on OVMF (as opposed to Mini-OS), removed the test. - comments - renamed XenbusReadInteger to XenBusReadUint64 - remove callback from IoData, use simple status instead - return a status from the synchronus io - Close protocol if blockfront init fail. - fix few debug print - Rename XenbusIo to XenBusIo - XenPvBlkWaitForBackendState will return an error if the new backend states is not the expected state. - Add the license License: This patch adds some files which are under the MIT license.

OvmfPkg/XenPvBlkDxe: Add BlockIo. Implement the BlockIo protocol. Change in V4: - Replace the license by the commonly used file header text. Change in V3: - assert(Media->BlockSize % 512 == 0) - Use Sector instead of Offset to issue IOs. Change in V2: - Remove blockIo2 headers. - Fix few comment. - file header, copyright - Rewrite few comment and error messages - No more callback - Improving block read/write, increase to the max size in one request (instead of only 8pages) - Fix lastblock when it's a cdrom - Do uninitialisation when fail to install fail - few comment - Licenses Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Anthony PERARD <anthony.perard@citrix.com> Reviewed-by: Jordan Justen <jordan.l.justen@intel.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@16274 6f19259b-4bc3-4df7-8a09-765794883524
