drm/i915: add SNB and IVB video sprite support v6 The video sprites support various video surface formats natively and can handle scaling as well. So add support for them using the new DRM core sprite support functions. v2: use drm specific fourcc header and defines v3: address Daniel's comments: - don't take struct mutex around register access (only needed for regs in the GT power well) - don't hold struct mutex across vblank waits - fix up update_plane API (pass obj instead of GTT offset) - add interlaced defines for sprite regs - drop unnecessary 'reg' variables - comment double buffered reg flushing Also fix w/h confusion when writing the scaling reg. v4: more fixes, address more comments from Daniel, and include Hai's fix - prevent divide by zero in scaling calculation (Hai Lan) - update to Ville's new DRM_FORMAT_* types - fix sprite watermark handling (calc based on CRTC size, separate from normal display wm) - remove private refcounts now that the fb cleanups handles things v5: add linear surface support v6: remove color key clearing & setting from update_plane For this version, I tested DPMS since it came up in the last review; DPMS off/on works ok when a video player is working under X, but for power saving we'll probably want to do something smarter. I'll leave that for a separate patch on top. Likewise with the refcounting/fb layer handling, which are really separate cleanups.

drm/i915: add SNB and IVB video sprite support v6 The video sprites support various video surface formats natively and can handle scaling as well. So add support for them using the new DRM core sprite support functions. v2: use drm specific fourcc header and defines v3: address Daniel's comments: - don't take struct mutex around register access (only needed for regs in the GT power well) - don't hold struct mutex across vblank waits - fix up update_plane API (pass obj instead of GTT offset) - add interlaced defines for sprite regs - drop unnecessary 'reg' variables - comment double buffered reg flushing Also fix w/h confusion when writing the scaling reg. v4: more fixes, address more comments from Daniel, and include Hai's fix - prevent divide by zero in scaling calculation (Hai Lan) - update to Ville's new DRM_FORMAT_* types - fix sprite watermark handling (calc based on CRTC size, separate from normal display wm) - remove private refcounts now that the fb cleanups handles things v5: add linear surface support v6: remove color key clearing & setting from update_plane For this version, I tested DPMS since it came up in the last review; DPMS off/on works ok when a video player is working under X, but for power saving we'll probably want to do something smarter. I'll leave that for a separate patch on top. Likewise with the refcounting/fb layer handling, which are really separate cleanups.

I'll leave that for a separate patch on top. Likewise with the refcounting/fb layer handling, which are really separate cleanups.
