Like I said "Thus, I consider that we need more sanity/constraints checks." at https://lore.kernel.org/lkml/b1e7dd6a-fc22-bba8-0abb-d3e779329bce@xxxxxxxxxxxxxxxxxxx/ , we want basic checks. That's a task for fbdev people who should be familiar with necessary constraints. Anyway, my two patches are small and low cost; can we apply these patches regardless of basic checks? _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
