Unveiling Arm Confidential Computing Architecture Software Stack
summary
Arm CCA spec hits mainline (released Sep 2024) and firmware lands as TF-A 2.20 with IMM 0.6; EDK2 staging is merging but DMA and hugepage support remain outstanding. Kernel guest v7 is merged, host KVM v9 posts in May and still blocks full upstreaming; QEMU backend and a device assignment path are working in-tree prototypes. Kata containers run on a QEMU backend via kata-deploy with CI, VCPU hotplug is blocked by kernel work, and end-to-end attestation uses Veraison attestation and a Trustee integration plus an endorsement API + local cache plan.
