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
