This file is called kms_cursor_legacy.c but it seems there are tests for
both legacy KMS and atomic KMS? That confused me :)

I think you meant this to be "cursor_hotspot" instead ?

maybe you can rename these to cursor_{width,height} ?

Also, there's https://docs.kernel.org/gpu/drm-uapi.html#c.DRM_CAP_CURSOR_WIDTH
and DRM_CAP_CURSOR_HEIGHT to query the hardware cursor size. Maybe you should
use that instead of assume a 64x64 cursor size ?
