[edk2] [PATCH 0/3] OvmfPkg/VirtioBlkDxe: map host address to device address

Posted by Brijesh Singh 7 years, 4 months ago

The patch updates the VirtioBlkDxe to use IOMMU-like member functions to map
the system physical address to device address for buffers (including vring,
device specific request and response pointed by vring descriptor, and any
furter memory reference by those request and response).
