From: Maarten Lankhorst Date: Thu, 3 Dec 2015 12:49:13 +0000 (+0100) Subject: drm/i915: Calculate watermark related members in the crtc_state, v4. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=92826fcdfc14;p=linux-beck.git drm/i915: Calculate watermark related members in the crtc_state, v4. This removes pre/post_wm_update from intel_crtc->atomic, and creates atomic state for it in intel_crtc. Changes since v1: - Rebase on top of wm changes. Changes since v2: - Split disable_cxsr into a separate patch. Changes since v3: - Move some of the changes to intel_wm_need_update.
