IGT-Version: 1.24-ge501741f
...
Testing format AR30(0x30335241) / modifier 0x100000000000003 on A.0
(kms_plane:1411) igt_fb-CRITICAL: Conversion not implemented (from format 0x30335241 to 0x78464749)

DRM_FORMAT_ARGB2101010 =  0x30335241
IGT_FORMAT_FLOAT = 0x78464749

{ .name = "ARGB2101010", .depth = 30, .drm_id = DRM_FORMAT_ARGB2101010,
  .pixman_id = PIXMAN_a2r10g10b10,

{ .name = "IGT-FLOAT", .depth = -1, .drm_id = IGT_FORMAT_FLOAT,
  .pixman_id = PIXMAN_rgba_float,

if ((drm_format_to_pixman(cvt->src.fb->drm_format) != PIXMAN_invalid) &&
    (drm_format_to_pixman(cvt->dst.fb->drm_format) != PIXMAN_invalid)) {
	cnvert_pixman(cvt);
	return;
...
igt_assert_f(false, "Conversion not implemented ...);

So wtf?

Are we somehow compiling igt with an old pixman causing
 #if PIXMAN_VERSION < PIXMAN_VERSION_ENCODE(0, 36, 0)
 #define PIXMAN_rgba_float PIXMAN_invalid
 #endif
to happen?

But the reference run shows it testing all the fancy YUV formats so
I don't think that can be the case.

And my CHV can run this test with ARGB2101010 just fine so
the code can't be totally broken.
