Hi Jason:

I am thinking about the process of merging process. Here are the dependence=
:

1) My patches depend on one patch in drm-intel/drm-intel-next. So it has to
go through drm.
My patches of GVT-g will go through drm-intel-next -> drm -> upstream.=20

2) Christoph's patches depends on my patches, but part of them are for VFIO=
.

a. If they are fully going through VFIO repo, they might have to wait my
patches to get landed first.

b. If only the GVT-g parts goes through GVT repo, and rest of them goes
through VFIO, the rest part still needs to wait.

What would be a better process?

Thanks,
Zhi.
