This still has the concept of a drawable owning a sprite, which is what I believe to be inconsistent with the exclusive ownership of the sprite from the XvAdapter. Abstracting the access, emulating more planes than physically present is intriguing, just requires careful scrutiny of the various runtime errors that the resource conflicts will then create and whether applications can handle that. Versus providing exclusive access to a sprite and the numerous virtual texture ports already provided. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
