2017-11-06IntelSiliconPkg IntelVTdDxe: Use ACPI table event to get DMAR tableStar Zeng4-30/+46
Use ACPI table event to get DMAR table instead of using ACPI SDT notification as ACPI SDT is optional and the default value of PcdInstallAcpiSdtProtocol is FALSE in MdeModulePkg.dec.

2017-10-30IntelSiliconPkg/VtdPeiSample: Add premem support.Jiewen Yao2-35/+201
Before memory is ready, this sample produces one VTd engine. After memory and silicon is initialized, this sample produces both IGD VTd engine and all-rest VTd engine by reinstall the FV_INFO_PPI. This update is to demonstrate how to support pre-mem VTd usage.

2017-10-30IntelSiliconPkg/VtdPmrPei: Add premem support.Jiewen Yao6-596/+1358
Remove memory discovered dependency to support both premem VTD_INFO_PPI and postmem VTD_INFO_PPI. If VTD_INFO_PPI is installed before memory is ready, this driver protects all memory region. If VTD_INFO_PPI is installed or reinstalled after memory is ready, this driver allocates DMA buffer and protect rest.

2017-10-26IntelSiliconPkg IntelVTdDxe: use gEfiAcpi10TableGuid for ACPI 1.0Star Zeng2-2/+2
According to definition (Acpi.h and MdePkg.dec), gEfiAcpiTableGuid = gEfiAcpi20TableGuid, and the code is trying to parse ACPI 2.0 first and then ACPI 1.0, but it uses gEfiAcpiTableGuid wrongly for ACPI 1.0, this patch is to fix it.

2017-09-20IntelSiliconPkg/IntelVTdPmrPei: Parse RMRR table.Jiewen Yao3-29/+624
In order to support PEI graphic, we let VTdPmrPei driver parse DMAR table RMRR entry and allow the UMA access. If a system has no PEI IGD, no RMRR is needed. The behavior is unchanged. If a system has PEI IGD, it must report RMRR in PEI phase. The PeiVTdPrm will program the IGD VTd engine to skip the RMRR region, and program the rest PCI VTd engine to skip the another DMA buffer allocated in PEI phase for other device driver.
