Y tiled fb will be rejected for gen < 9, should use X/linear for those.
Actually using X/linear for gen >= 9 would also be interesting to make
sure we reject 90/270 for those even when they are otherwise listead as
supported rotations.

Also why hand roll the fb creation instead of using the igt_fb stuff?

What's this doing here?

These seem rather needlessly hardcody. I would suggest looking at the
supported rotations for each plane and picking some invalid ones based
on that.

Are you referring to the __gem_set_tiling call? Since this didn't fail
on BDW and I don't see any logic in i915_gem_set_tiling which
implements this.

Yup, good point

Sorry, I must be missing something, isn't that what it already does?
I've just picked the invalid rotations for the primary, cursor and sprite
planes.

No, I mean the addfb. Note that the current logic in addfb is sort of
silly, and I tried to fix it in
https://lists.freedesktop.org/archives/intel-gfx/2016-February/087670.html
but no review so far.

I mean that instead of hardcoding the assumption which rotation are
unsupported, you could actually look at what the driver reports as
supported vs. not.
