Out of interest, how was this tested? There is no 32x8 modifier in the
format list in format_modifiers_afbc[], so it seems like it shouldn't
be possible to get a 32x8 buffer on a plane at all.
You can use the drm_info utility from
https://gitlab.freedesktop.org/emersion/drm_info to validate that the
list of supported formats/modifiers for each plane matches your
expectation.
Cheers,
Daniel
