From 1875fe7ba15020a0d45856d16c17e57ebcbc0bec Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 12 Dec 2017 11:35:32 +0000 Subject: [PATCH] drm/i915: Downgrade misleading "Memory usable" message Git-commit: 1875fe7ba15020a0d45856d16c17e57ebcbc0bec Patch-mainline: v4.16-rc1 References: FATE#322643 bsc#1055900 It never meant what it said, as it was always the total size of the Global GTT and not a limit upon memory usage. Originally it served as a quick guide to the largest batch that could be submitted by userspace, an approximation to its maximum RSS, but was phrased badly. Today with the 48b ppgtt, it is even more meaningless. Replace with a more specific debug message; those wanting to know how much "video ram" they have should consult the userspace libraries for the relevant approximation.
