Tom Lendacky d334a5637d iommu/amd: Reduce amount of MMIO when submitting commands ... As newer, higher speed devices are developed, perf data shows that the amount of MMIO that is performed when submitting commands to the IOMMU causes performance issues. Currently, the command submission path reads the command buffer head and tail pointers and then writes the tail pointer once the command is ready. The tail pointer is only ever updated by the driver so it can be tracked by the driver without having to read it from the hardware. The head pointer is updated by the hardware, but can be read opportunistically. Reading the head pointer only when it appears that there might not be room in the command buffer and then re-checking the available space reduces the number of times the head pointer has to be read.
