Hi, I think maybe we've found the issue that many of you with Skylake or newer systems were seeing with IGD assignment. There's a wraparound issue with the GTT programming, as discovered by Alexander Indenbaum. I still don't have access to anything newer than Broadwell, so I'm interested in test reports from anyone that's currently using IGD assignment or tried previously and maybe didn't get any output or garbled output, whether on Skylake, Kabylake, or regression testing on older IGD as well. Please add the following patch to your QEMU build and report if it breaks anything, fixes anything, or even if it stays the same:
