From eacd0ecb98a93e3ff83a4479eadeb9cda05d3579 Mon Sep 17 00:00:00 2001 From: Fedora Kernel Team Date: Mon, 20 Jun 2016 12:41:01 +0200 Subject: [PATCH 11/17] drm/i915/gen9: Calculate plane WM's from state Upstream: since drm-intel-next-2016-05-22 commit 33815fa55b31a5de4b197c09926ecab3dfb79732 Author: Matt Roper AuthorDate: Thu May 12 07:06:05 2016 -0700 Commit: Matt Roper CommitDate: Fri May 13 07:34:12 2016 -0700 drm/i915/gen9: Calculate plane WM's from state In a future patch we'll want to calculate plane watermarks for in-flight atomic state rather than the already-committed state.
