Cnuas is under active research and
release preparation. The paper is published as an arXiv preprint, and the six-patch QEMU v3
contribution series has been submitted to qemu-devel and is in active discussion
with upstream maintainers. The PCI ID patches for CnuasNIC and CnuasGPU have received
Reviewed-by tags; the device and test patches remain under review and the series
is pending upstream merge. Source repository publication
is pending upstream merge of the QEMU and Linux patches.
This page will be updated with authoritative repository links and submission records as each item becomes public. A "pending" status does not imply submission, acceptance, or endorsement by a prospective venue or upstream project.
