SourceLevelDebugPkg DebugCommUsb3: Return error when debug cap is reset

2018-03-20T12:23:53+00:00

When source level debug is enabled, but debug cable is not connected, XhcResetHC() in XhciReg.c will reset the host controller, the debug capability registers will be also reset. After the code in InitializeUsbDebugHardware() sets DCE bit and LSE bit to "1" in DCCTRL, there will be DMA on 0 (the value of some debug capability registers for data transfer is 0) address buffer, fault info like below will appear when IOMMU based on VTd is enabled.

SourceLevelDebugPkg DebugUsb3: Re-Support IOMMU

2018-03-15T06:14:26+00:00

de8373fa07f87ca735139bb86c51e2c29fb1d956 could not handle two cases. 1. For the case that the USB3 debug port instance and DMA buffers are from PEI HOB with IOMMU enabled, it was to reallocate the DMA buffers by AllocateAddress with the memory type accessible by SMM environment. But reallocating the DMA buffers by AllocateAddress may fail. 2. At S3 resume, after the code is transferred to PiSmmCpuDxeSmm from S3Resume2Pei, HOB is still needed to be used for DMA operation, but PiSmmCpuDxeSmm has no way to get the HOB at S3 resume. The patch is to re-support IOMMU. For PEI, allocate granted DMA buffer from IOMMU PPI, register IOMMU PPI notification to reinitialize hardware with granted DMA buffer if IOMMU PPI is not present yet. For DXE, map DMA buffer by PciIo in PciIo notification for early DXE, and register DxeSmmReadyToLock notification to reinitialize hardware with granted DXE DMA buffer accessible by SMM environment for late DXE. DebugAgentLib has been managing the instance as Handle in HOB/SystemTable. The Handle(instance) from DebugAgentLib can be used directly in DebugCommunicationLibUsb3. Then DebugCommunicationLibUsb3 could get consistent Handle(instance) from DebugAgentLib.
