drm/i915: add render state initialization HW guys say that it is not a cool idea to let device go into rc6 without proper 3d pipeline state. For each new uninitialized context, generate a valid null render state to be run on context creation. This patch introduces a skeleton with empty states. v2: - No need to vmap (Chris Wilson) - use .c files for state (Daniel Vetter) - no need to flush as i915_add_request does it - remove parameter for batch alloc size - don't wait for the init (Ben Widawsky) v3: - move to cpu/gpu (Chris Wilson) Tested-by: Kristen Carlson Accardi <kristen@linux.intel.com> (v1) Tested-by: Oscar Mateo <oscar.mateo@intel.com> Reviewed-by: Damien Lespiau <damien.lespiau@intel.com> Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
