This patch-set introduces the GEM proxy which is a kind of GEM whose backing physical memory is pinned and produced by guest VM and is used by host as read only. The patch is separated from the "Dma-buf support for Gvt-g" patch-set. (Joonas) v2: - return -ENXIO when pin and map pages of GEM proxy to kernel space. (Chris) - update the patch description and subject to just mention objects w/o backing storage, instead of "GEM proxy". (Joonas) Here are the histories of this patch in "Dma-buf support for Gvt-g" patch-set: v14: - return -ENXIO when gem proxy object is banned by ioctl. (Chris) (Daniel) v13: - add comments to GEM proxy. (Chris) - don't ban GEM proxy in i915_gem_sw_finish_ioctl. (Chris) - check GEM proxy bar after finishing i915_gem_object_wait. (Chris) - remove GEM proxy bar in i915_gem_madvise_ioctl. v6: - add gem proxy barrier in the following ioctls.
