Hey,

Has NV12 been tested at all on skylake with rotation?

y_min_scanlines = 16 for 90°/270° rotation with cpp=1
skl_needs_memory_bw_wa() doubles the scanlines required,
which will trigger the following error quite easily when patching kms_rotation_crc to use NV12:

[   67.049190] [drm:skl_compute_wm_levels [i915]] Requested display configuration exceeds system watermark limitations
[   67.049212] [drm:skl_compute_wm_levels [i915]] [PLANE:28:plane 1A] blocks required = 161/572, lines required = 32/31

If we violate the spec for the workaround, by using 31 lines instead of 32 for 90/270
rotation, the tests work but this needs to be solved first before we can move forward.
