This patch introduces a guest's framebuffer sharing mechanism based on dma-buf subsystem. With this sharing mechanism, guest's framebuffer can be shared between guest VM and host. v17: - modify VFIO_DEVICE_GET_GFX_DMABUF interface. (Alex) v16: - add x_hot and y_hot. (Gerd) - add flag validation for VFIO_DEVICE_GET_GFX_DMABUF. (Alex) - rebase 4.14.0-rc6. v15: - add VFIO_DEVICE_GET_GFX_DMABUF ABI. (Gerd) - add intel_vgpu_dmabuf_cleanup() to clean up the vGPU's dmabuf. (Gerd) v14: - add PROBE, DMABUF and REGION flags. (Alex) v12: - refine the lifecycle of dmabuf. v9: - remove dma-buf management. (Alex) - track the dma-buf create and release in kernel mode. (Gerd) (Daniel) v8: - refine the dma-buf ioctl definition.(Alex) - add a lock to protect the dmabuf list. (Alex) v7: - release dma-buf related allocations in dma-buf's associated release function. (Alex) - refine ioctl interface for querying plane info or create dma-buf. (Alex) v6: - align the dma-buf life cycle with the vfio device. (Alex) - add the dma-buf related operations in a separate patch. (Gerd) - i915 related changes. (Chris) v5: - fix bug while checking whether the gem obj is gvt's dma-buf when user change caching mode or domains. Add a helper function to do it. (Xiaoguang) - add definition for the query plane and create dma-buf. (Xiaoguang) v4: - fix bug while checking whether the gem obj is gvt's dma-buf when set caching mode or doamins. (Xiaoguang) v3: - declare a new flag I915_GEM_OBJECT_IS_GVT_DMABUF in drm_i915_gem_object to represent the gem obj for gvt's dma-buf. The tiling mode, caching mode and domains can not be changed for this kind of gem object. (Alex) - change dma-buf related information to be more generic. So other vendor can use the same interface. (Alex) v2: - create a management fd for dma-buf operations. (Alex) - alloc gem object's backing storage in gem obj's get_pages() callback.
