Creating a new fb using a Y-tiled object and Y/X fb modifier will not trigger the original WARN. It'll be triggered only if the fb is going to be pinned -- and flipped. I am not sure how to get that WARN to be triggered with the existing suite of igt tests.

Ah yes, you would need to attempt display it, not even necessarily flip it. I am sure there are tests which do that. :) I know from recent activity kms_rotation_crc for example creates a Y tiled FB and displays it. So maybe borrow some code to start with from there.

Even better, kms_flip_tiling does the majority of what is needed here already. Just drop in a subtest which will do set_tiling and that should be good.

This is because the WARN is triggered only when pinning/fencing a Y-tiled fb that has a rotated view (90/270 degree rotation) that none of the IGT tests can do. I looked at and wrote a subtest in kms_rotation_crc but the WARN was not triggered because IGT does not support atomic flip/commit yet. Currently, since it does a SetPlane first, the object has a normal view and its map_and-fenceable bit is set, however, when the rotation property is applied, the object though has a rotated view, its map_and-fenceable bit never gets updated and stays 1 and hence the warning doesn't get triggered. I am copying the subtest code below for reference.

If you just avoided rendering to the fb (paint_squares) I think it might have worked. Unfortunately before reading your e-mail thoroughly I rushed and developed my own POC so you will now see a patch series I copied you on. That triggers the WARN nicely. But your approach, localized changes to kms_rotation_crc, is probably better. So feel free to refine your test case and we can drop my patch series.
