2014-10-29OvmfPkg/XenPvBlkDxe: Add BlockFront client.Samuel Thibault
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.
