Hi all, After merging the drm-misc tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/gpu/drm/nouveau/nouveau_ttm.c: In function 'nouveau_ttm_init': drivers/gpu/drm/nouveau/nouveau_ttm.c:320:19: error: implicit declaration of function 'swiotlb_nr_tbl' [-Werror=implicit-function-declaration] 320 | need_swiotlb = !!swiotlb_nr_tbl(); | ^~~~~~~~~~~~~~ Caused by commit ee5d2a8e549e ("drm/ttm: wire up the new pool as default one v2") I have used the drm-misc tree from next-20201029 for today. -- Cheers, Stephen Rothwell
