virtio

Phyllome leverages 3D acceleration within guest operating systems extensively, in three different modes depending on the situation.

• vfio-pci : Passing through a complete physical Graphical Processing Unit (GPU) to the guest via the vfio-pci driver
• vfio-mdev : Sharing a fraction of a compatible physical GPU such as those using single-root input/output virtualization (SR-IOV), via the vfio-mdev driver
• vfio-gpu : Using some capabilities of the host GPU, via the vfio-gpu driver, which creates a virtual GPU as is used in Chromium OS and Spectrum OS
