From: Daniel Vetter Date: Tue, 10 Feb 2015 17:16:10 +0000 (+0000) Subject: drm/i915: Switch intel_fb_align_height to fb format modifiers X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=091df6cbf248811150552d51dacb9dc1fe6b0a23;p=linux-beck.git drm/i915: Switch intel_fb_align_height to fb format modifiers With this we can treat the fb format modifier completely independently from the fencing mode in obj->tiling_mode in the initial plane code. Which means new tiling modes without any gtt fence are now fully support in the core i915 driver code. v2: Also add pixel_format while at it, we need this to compute the height for the new tiling formats.
