Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2171891 The region provisioning flow involves selecting interleave ways + granularity settings for a region, and then programming the decoder topology to meet those constraints, if possible. For example, root decoders set the minimum interleave ways + granularity for any hosted regions. Given decoder programming is not atomic and collisions can occur between multiple requesting regions userspace will be responsible for conflict resolution and it needs these attributes to make those decisions.
