Subject: [RFC 0/6] DxeBmDmaLib
Date: Mon, 9 Jan 2017 18:16:55 -0600 [thread overview]
Message-ID: <1484007421-15462-1-git-send-email-leo.duran@amd.com> (raw)
This patch-set provides an abstraction layer for DMA operations implemented
by the PciHostBridgeDxe driver. The intent is to then allow override of this
library as may be required by specific hardware implementations, such as
AMD's Secure Encrypted Virtualization (SEV).
This new (BmDmaLib class) library is modeled after the existing DmaLib
plus an extra DmaAbove4GB (BOOLEAN) parameter in the Map and Allocate
interfaces, so that decisions can be made about the need to allocate DMA
buffers below the 4GB boundary.
Leo Duran (6):
MdeModulePkg: Add DxeBmDmaLib library
ArmVirtPkg: Modify .DSC files that include PciHostBridgeDxe driver
CorebootPayloadPkg: Modify .DSC files that include PciHostBridgeDxe
driver
MdeModulePkg: Modify .DSC files that include PciHostBridgeDxe driver
OvmfPkg: Modify .DSC files that include PciHostBridgeDxe driver
MdeModulePkg: Modify PciHostBridgeDxe to use new BmDmaLib library.
