Hi,
It's nice to see this full stack posted - thanks!
Are there any pointers to information on attestation and similar
measurement things? In particular, are there any plans for a vTPM
for Realms - if there were, it would make life easy for us, since we
can share some user space stuff with other CoCo systems.

> - TF-RMM/KVM currently doesn't support the optional features of PMU,
> SVE and Self-hosted debug (coming soon).
> - The RSI_HOST_CALL structure alignment requirement is reduced to match

> - RMI/RSI version numbers do not match the RMM spec. This will be
> resolved once the spec/implementation is complete, across TF-RMM+Linux stack.
>
> We plan to update the stack to support the latest version of the RMMv1.0 spec
> in the coming revisions.
>
> This release includes the following components :
>
> a) Linux Kernel
> i) Host / KVM support - Support for driving the Realms via RMI. This is
> dependent on running in the Kernel at EL2 (aka VHE mode). Also provides
> UABI for VMMs to manage the Realm VMs. The support is restricted to 4K page
> size, matching the Stage2 granule supported by RMM. The VMM is responsible
> for making sure the guest memory is locked.
>
> TODO: Guest Private memory[10] integration - We have been following the

> Realm-EL1, using RSI services. This includes virtio support (virtio-v1.0
> only). All I/O are treated as non-secure/shared.
>

> as mentioned above.
> d) kvm-unit-tests - Support for running in Realms along with additional tests
> for RSI ABI.
