GVT workload scheduler needs special host LRC contexts, the so called "shadow LRC context" to submit guest workload to host i915. During the guest workload submission, workload scheduler fills the shadow LRC context with the content of guest LRC context: engine context is copied without changes, ring context is mostly owned by host i915. v8: - Remove the graph temporarily. (Chris) - Use interruptible mutex_lock. (Chris) - Rename the function name of creating a GVT context. (Chris) - Add the missing declaration in i915_drv.h (Chris) v7: - Move chart to a better place. (Joonas) v6: - Make GVT code as dead code when !CONFIG_DRM_I915_GVT. (Chris) v5: - Only compile this feature when CONFIG_DRM_I915_GVT is enabled. (Tvrtko) - Rebase the code into new repo. - Add a comment about the ring buffer size. (Joonas) v2: Mostly based on Daniel's idea. Call the refactored core logic of GEM context creation service and LRC context creation service to create the GVT context.
