commit cf6c467d67d319e239aec57d7ba31cb9946f29bf Author: Christian König christian.koenig@amd.com AuthorDate: Tue Jan 10 14:08:28 2017 +0100 Commit: Alex Deucher alexander.deucher@amd.com CommitDate: Fri Jan 27 12:20:33 2017 -0500

drm/ttm: add BO priorities for the LRUs

This way the driver can specify a priority for a BO which has the effect that a BO is only evicted when all other BOs with a lower priority are evicted first.
