Yes, we now have a version that supports the final RMM-v1.0
specification (RMM-v1.0-EAC5). We also have the UEFI EDK2 firmware
support for Guests in Realm world.
We are planning to post the changes for review in the v6.8-rc cycle. We
are trying to integrate the guest_mem support (available in v6.8-rc1) as
well as reusing some of the arm64 kvm generic interface for configuring
the Realm parameters (e.g., PMU, SVE_VL etc).
Here is a version that is missing the items mentioned above, based
on v6.7-rc4, if anyone would like to try.
Also, the easiest way to get the components built and model kick started
is using the shrinkwrap [6] tool, using the cca-3world configuration.
The tool pulls all the required software components, builds (including
the buildroot for rootfs) and can run a model using these built
components.
