[PATCH 0/2] virtio-gpu: hardware specification
Hi folks, Lets kick off the virtio-gpu review process, starting with the virtio protocol. This is a tiny patch series for qemu. Patch #1 carries the header file describing the virtual hardware: config space, command structs being sent over the rings, defines etc. Patch #2 adds a text file describing virtio-gpu to docs/specs/. It covers 2D support only for now. For anybody who wants to dig a
