"can't boot up" means guest doesn't boot at all, guest will stop to booting after adding vga device, detail log in attachment.

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?

Yes, Linux VM update to a 3.18 kernel. The RHEL7.2 default kernel (should be 3.10) VM don't boot up with IGD pass-through, and Windows can't boot up either.

Hi, > I can boot up Linux VM with IGD pass-through with latest qemu (without > any additional patch), guest run 3D "nexuiz" and get 180fps. That is a pretty recent linux guest I assume? Tried older kernels too, possibly even the old userspace xorg driver? Do windows guest work as well? cheers, Gerd
Re: [Qemu-devel] [Xen-devel] [PATCH v4] igd-passthrough-i440FX: convert to realize()
Stefano, Patch http://marc.info/?l=qemu-devel&m=145137863501079 don't works for qemu at all, some conflict when git apply. Patch http://marc.info/?l=qemu-devel&m=145137863501079 is based on patch http://marc.info/?l=qemu-devel&m=145172165010604, right? I can boot up Linux VM with IGD pass-through with latest qemu (without any additional patch), guest run 3D "nexuiz" and get 180fps. Will try the two patch together later.

Re: [Qemu-devel] [Xen-devel] [PATCH v4] igd-passthrough-i440FX: convert to realize()
Qemu with the patch can't boot VM with IGD pass-through, I'm checking if it works w/o this patch to eliminate the environment influence.

Re: [Qemu-devel] [Xen-devel] [PATCH v4] igd-passthrough-i440FX: convert to realize()
Since you are at it, could you please let me know how well igd passthrough works without this bugfix: http://marc.info/?l=qemu-devel&m=145172165010604 which is about to land in QEMU. I guess it doesn't work at all? I am asking because I would like to know the level of support we need to provide to igd passthrough with the latest QEMU release (2.5).
