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(); | ^~~~~~~~~~~~~~

Mhm, thanks for the note. Looks like there is some merge conflict to me.

In my tree there is an "#if IS_ENABLED(CONFIG_SWIOTLB) && IS_ENABLED(CONFIG_X86)" around that line making sure the function is available.

Going to take a look later today.

Christian.

I have used the drm-misc tree from next-20201029 for today.
