* OvmfPkg/PvScsiDxe: Reset device on ExitBootServices()Liran Alon2020-03-301-0/+1
| | | | | | | | | | | | This causes the device to forget about the request/completion rings. We allocated said rings in EfiBootServicesData type memory, and code executing after ExitBootServices() is permitted to overwrite it.

* OvmfPkg/PvScsiDxe: Introduce DMA communication bufferLiran Alon2020-03-301-0/+20
| | | | | | | | | | | | | | | | | | | In case device is constrained by IOMMU or guest is running under AMD SEV, input/output buffers provided to device (DataBuffer and SenseData) needs to be explicitly mapped to device by PciIo->Map(). To avoid the overhead of mapping/unmapping the DataBuffer and SenseData to the device for every SCSI requst (and to simplify code), introduce a single DMA communication buffer that will be mapped to device on initialization. When a SCSI request needs to be sent to device, the DataBuffer and SenseData will be copied from/to the DMA communication buffer as required. This will be done by the following commits.

* OvmfPkg/PvScsiDxe: Setup requests and completions ringsLiran Alon2020-03-301-0/+17
| | | | | | | | | | | | | | | | These rings are shared memory buffers between host and device in which a cyclic buffer is managed to send request descriptors from host to device and receive completion descriptors from device to host. Note that because device may be constrained by IOMMU or guest may be run under AMD SEV, we make sure to map these rings to device by using PciIo->Map().

* OvmfPkg/PvScsiDxe: Report the number of targets and LUNsLiran Alon2020-03-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | Implement EXT_SCSI_PASS_THRU.GetNextTarget() and EXT_SCSI_PASS_THRU.GetNextTargetLun(). ScsiBusDxe scans all MaxTarget * MaxLun possible devices. This can take unnecessarily long for large number of targets. To deal with this, VirtioScsiDxe has defined PCDs to limit the MaxTarget & MaxLun to desired values which gives sufficient performance. It is very important in virtio-scsi as it can have very big MaxTarget & MaxLun. Even though a common PVSCSI device has a default MaxTarget=64 and MaxLun=0, we implement similar mechanism as virtio-scsi for completeness. This may be useful in the future when PVSCSI will have bigger values for MaxTarget and MaxLun.
