2018-03-15SourceLevelDebugPkg DebugUsb3: Re-Support IOMMUStar Zeng1-2/+51
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.

2015-04-01SourceLevelDebugPkg: Use CPU Local APIC timer to handle timeout.Jeff Fan1-26/+1
Use CPU Local APIC timer to handle timeout when read data from debug port, instead of the TimerLib in Debug Communication lib instances. It could remove much duplicated code in Debug Communication Lib instances.

If host sends more than 8 bytes of data, BABBLE error would happen if USB3 debug library uses 8 byte of buffer to read data. We need use MaxPacketSize in USB3 debug descriptor to create buffer and read data into this buffer.
