From f28225dda2a2bf1e2d96bbe44b45d43a7d5071d3 Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Thu, 12 May 2016 07:05:59 -0700 Subject: [PATCH 05/17] drm/i915/gen9: Store plane minimum blocks in CRTC wm state (v2) This will eventually allow us to re-use old values without re-calculating them for unchanged planes (which also helps us avoid re-grabbing extra plane states). v2: - Drop unnecessary memset's; they were meant for a later patch (which got reworked anyway to not need them, but were mis-rebased into this one.
