From 6b622063451d0756f5f3c5380fd7569afae1c377 Mon Sep 17 00:00:00 2001 From: Philip Yang Date: Wed, 17 Apr 2019 22:15:19 +0000 Subject: [PATCH 1/2] drm: increase drm mmap_range size to 1TB MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit After patch "drm: Use the same mmap-range offset and size for GEM and TTM", application failed to create bo of system memory because drm mmap_range size decrease to 64GB from original 1TB. This is not big enough for applications. Increase the drm mmap_range size to 1TB.
