From 03af79e0b801fa5ea817f71a22a932d4b5b62b4b Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Wed, 26 Oct 2016 15:41:36 +0200 Subject: [PATCH] drm/i915/gen9+: Use the watermarks from crtc_state for everything, v2. There's no need to keep a duplicate skl_pipe_wm around any more, everything can be discovered from crtc_state, which we pass around correctly now even in case of plane disable. The copy in intel_crtc->wm.skl.active is equal to crtc_state->wm.skl.optimal after the atomic commit completes. It's useful for two-step watermark programming, but not required for gen9+ which does it in a single step. We can pull the old allocation from old_crtc_state.
