Hi Simon,

a KMS property is what we have on vkms TODO [1] and the module parameter
was Maíra's first step to open a discussion for this property [2].
AFAIK, we would need to create the KMS property first, but it seems
there isn't an userspace case/need to support this API change.
Do you know any valid use cases to support a bkg color property?

BR,

Melissa
