From: Thomas Zimmermann Date: Tue, 23 Jul 2019 07:54:23 +0000 (+0200) Subject: drm/mgag200: Pin displayed cursor BO to video memory X-Git-Tag: v5.4-rc1~106^2~18^2~125 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a0fd72d2c95b56c78feec0867f2077b5ff5991e6;p=thirdparty%2Fkernel%2Flinux.git drm/mgag200: Pin displayed cursor BO to video memory The cursor BO has to be pinned to video ram while it's being displayed. With the current code, the BO might be pinned to system memory instead. The patch fixes this problem.
