Many hypercalls are missing in current RFC, including the grant map/unmap ones. But a part of the idea is to still having some hypercalls out of scope (mainly legacy and toolstack-specific ones) to reduce the complexity. > Jan > Teddy Astie | Vates XCP-ng Developer XCP-ng & Xen Orchestra - Vates solutions web: https://vates.tech
