Hi Alex, Michel & Andrey, [PATCH] drm/amd/display: assign fb_location only if bo is pinned [PATCH 2/2] drm/amd/display: cleanup addReq and fix fb_location should be dropped and instead: [PATCH] drm/amd/display: fix high part address in dm_plane_helper_prepare_fb() should be reviewed . With this change I don’t have clean-up addReq, as I get the gpu_offset required for high part in dm_plane_helper_prepare_fb(). Thanks.

The latter on its own couldn't really solve the problem anyway: While a BO is unpinned, its MC address can change at any time. The MC address programmed to the hardware must be determined while the BO is and stays pinned. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
