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.

> Subject: [PATCH v10 00/10] Introduce the implementation of GVT context
>
> 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.

> Acknowledgment
> ---------------
>
> iGVT-g implementation is several years effort and many people contributed to
> the code. There names are not here yet. In later formal patchset we will reflect
> individual's contribution.
>
> Meanwhile, in the previous iGVT-g related discussion, Daniel, Chris and Joonas
> ever gave very good inputs. We appreciate them and look forward to more
> comments/suggestions from community.
