virtio-accel-device

Transport-neutral device-side state and validation, including bounded generational object IDs. A future rust-vmm adapter translates descriptor chains into this layer; the command engine and provider backend never see guest addresses or virtqueue descriptors.

Part of the virtio-accel workspace: an experimental native-Rust protocol and implementation stack for a transport-neutral virtual accelerator device. Portable crates contain no host-OS or vendor APIs; host integrations live in separate adapter crates and never become their dependencies. The project claims no Virtio device ID.

Portability tier: alloc-portable — core + alloc; no operating system, filesystem, sockets, or threads.

The protocol 1.0 numeric opcodes, statuses, and payload layouts are versioned review inputs for independent implementation, frozen for the portable v1.0 baseline by the final freeze audit. This remains pre-standardization work and claims no Virtio device ID.
