There is another bug, using pci_default_write_config() doesn't fly as this checks writes against wmask and the registers in question are not whitelisted ... I've just rebased my igd patch series which (among other stuff) fixes that bug: https://www.kraxel.org/cgit/qemu/log/?h=work/igd git://git.kraxel.org/qemu work/igd Can you give it a spin? Also: what does "can't boot up" mean exactly? Guest doesn't boot at all? Guest boots, but igd/console/Xorg doesn't work? In case of the latter: Any chance to login via network and get a kernel log? thanks, Gerd
