Mostly 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... v5: - Drop PPGTT related patches. - Let most functions take struct drm_i915_private * - Fixed some misspelled words in Kconfig - Only complied some feature when CONFIG_DRM_I915_GVT=y - Drop the fecne related changes, will send it after this series. v4: - Based on the latest drm-intel-nightly branch. - Drop PPGTT refactor patches. (GVT-g will use LRI to load PDPs) - Drop i915_gem_context() refactor patches, reuse kernel context functions. (Dave Gordon) - Drop context allocation params and refactor as the lrc deferred allocation function has been refactored in another styles. - Re-wrtie GVT context creation function 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. st 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. We are trying to get more familiar with i915 but may still have gaps. We are willing to adopt suggestions to keep improving. We hope to work with community together to make iGVT-g a great component in i915 to support graphics virtualization. Thanks!
