Also there is no debugfs-related flag for amdgpu - it seems or amdgpu should depend on CONFIG_DEBUG_FS_ALLOW_ALL, or = it should have separate debugfs flag to enable/disable debugfs usage (it is se= ems very possible as it was working early w/o access to debugfs). --=20 You may reply to this email to add a comment.
