[edk2] [PATCH 1/3] OvmfPkg/VirtioBlkDxe: map VRING using VirtioRingMap()

2017-08-25 Thread Brijesh Singh
When device is behind the IOMMU then driver need to pass the device address when programing the bus master. The patch uses VirtioRingMap() to map the VRING system physical address to device address. Cc: Ard Biesheuvel Cc: Jordan Justen Cc: Tom Lendacky Cc: Laszlo Ersek Contributed-under: Tiano
