Thanks for working on this, I have several questions: 1) Is there an example implementation of the logging in the drivers? We need a real user in order to merge this. 2) Is the logging based on IOVA or VA? How the DMA isolation is being done with this? Do we need a SET_LOGGING_ASID uAPI for this? (We had some discussion on this in the past).
