vmf_insert_mixed() is only built for MMU configs, and the attached config does not set/enable MMU. Maybe this driver should depend on MMU, like several other drm drivers do. Also, lima_gem.c needs this line to be added to it: --- mmotm-2019-0405-1828.orig/drivers/gpu/drm/lima/lima_gem.c +++ mmotm-2019-0405-1828/drivers/gpu/drm/lima/lima_gem.c @@ -1,6 +1,7 @@ // SPDX-License-Identifier: GPL-2.0 OR MIT /* Copyright 2017-2019 Qiang Yu <yuq...@gmail.com> */ +#include <linux/mm.h> #include <linux/sync_file.h> #include <linux/pfn_t.h> -- ~Randy _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
