[RFC PATCH v2 1/9] Add Rust SEV library as subproject |
Date: |
Wed, 4 Oct 2023 16:34:10 -0400 |
The Rust sev library provides a C API for the AMD SEV launch ioctls, as
well as the ability to build with meson. Add the Rust sev library as a
QEMU subproject with the goal of outsourcing all SEV launch ioctls to C
APIs provided by it.
