LibVF.IO: vGPU & SR-IOV on Consumer GPUs using Nim

" summary

Covers LibVF.IO’s work to enable vGPU/SR-IOV on consumer GPUs for free open-source desktop OSes, focusing on the new LIME Runtime (Lime Is Mediated Emulation). Explains and compares VFIO-Mdev API, Virgl vs. hardware GPU virtualization (SR-IOV) vs. soft mdev, and common driver virtualization approaches (Intel i915, AMD GPU-IOV module, Nvidia), plus efforts to run LibVF.IO with Xen for Qubes OS and the projected benefits of bringing hardware vGPU isolation and performance to everyday free-software users.
