Hello, I have been developing an x64 OS with USB support, and noticed that, every time I introduced a bug into my xHCI driver, QEMU would often silently continue successfully where real hardware that I tested would error.
Would it be helpful if I were to try and add warning messages into QEMU logs for incorrect but recoverable usage of xHCI? This could aid other OS & driver developers, without breaking drivers that rely on the permissiveness of QEMU, but I'm not sure that it is the mission of QEMU to have conformance warnings. >From Stuart
