Sorry, we indeed found Intel windows guest graphic driver couldn't be bind when GMS memory size is zero. And we have fixed it and the next intel windows driver release will contain this fix. So currently please use x-igd-gms in legacy mode to work around this. BTW, how did you know window

[Qemu-devel] [PATCH] vfio/pci-quirks: Set non-zero GMS memory size for IGD

2017-07-24 Thread Dmitry Fleytman
There is a claim that GMS memory is unused however Intel Windows 10 drivers starting from V.4534 (10/7/2016) allocate extra ~4G memory when GMS size set to 0. This patch fixes this issue by seting IGD GMS memory size to minimum by changing default value of x-igd-gms device parameter.
