Hi G.G.,
Thanks for doing this, looks ok in general. Few comments below.

Could remove the FB, cairo surface already here, so we don't need the
array and a second loop below?

Hm not sure why legacy commit wouldn't work here. It will result in a
modeset with only the primary plane on without rotation. Otoh universal
commit doesn't (or at least used not to) support full modesets, so if
we'd have to change the mode here then that wouldn't work. Did you try
to run the test with multiple outputs?

Imo s/clip_squares_cnt/plane_cnt/ would be clearer.

Could be just
for (i = 0; i < 4; i += clip_squares_cnt)
test_plane_clipping_square(data, pipe, output, mode,
clip_squares + i,
clip_squares_cnt);
