[Intel-gfx] [PATCH v10 00/10] Introduce the implementation of GVT context

[Wang, Zhi A]

Hi Chris:
    As Joonas is on vacation, can you pick my patches? or if you have some comments I can continue improving them.

Thanks,
Zhi.

> This patchset introduces the implementation of GVT context. GVT context is a
> special GEM context used by GVT-g. GVT-g uses it as the shadow context.It
> doesn't have a drm client nor a PPGTT. And it requires a larger ring buffer with
> several special features need by GVT-g workload scheduler like context status
> change notification, context single submission...

> Difference from community release
> ---------------------------------
> 
> This patchset is different from regular iGVT-g code release[4], which is still
> based on old host-mediated architecture. Furthermore, this patchset only
> supports BDW whereas code release supports HSW/BDW/SKL.
> We will add SKL support later based on this RFC code and HSW support will be
> dropped.
> 
> Internally we tested this RFC patchset with both linux and windows VM and the
> architecture changes work fine.

> iGVT-g implementation is several years effort and many people contributed to
