Explore the implementation of Confidential Device Assignment (CoDA) in Huawei's practice for supporting legacy devices in this technical talk. Learn about virtCCA, Huawei's implementation of the CCA software stack using ARM TrustZone Secure-EL2, and how it enables legacy PCIe devices to be assigned to Confidential Virtual Machines (CVMs). Understand how the PCI Protection Controller (PCIPC) in Huawei's Kunpeng CPU facilitates CoDA, allowing applications like confidential machine learning while enhancing CVM I/O performance. Discover benchmark results showing that CVMs with assigned devices perform nearly identically to normal VMs, addressing limitations of current TDISP-based development which lacks support for market-available devices.
