Projekti virtio-nvgpu zhvillon nj\u00eb pajisje virtio, e cila lejon qasje n\u00eb GPU-n\u00eb NVIDIA nga sistemet mysafir q\u00eb funksionojn\u00eb n\u00ebn menaxhuesin KVM, me humbje minimale n\u00eb performanc\u00eb. Ai p\u00ebrfshin nj\u00eb modul b\u00ebrthamor, i ngarkuar n\u00eb sistemin mysafir dhe nj\u00eb pajisje virtio, e cila ekzekutohet n\u00eb an\u00ebn e mjedisit host.

Sipas vler\u00ebsimeve t\u00eb zhvilluesve, humbja e performanc\u00ebs gjat\u00eb qasjes n\u00eb GPU nuk kalon 2%. Shpejt\u00ebsia e lart\u00eb arrihet fal\u00eb ridrejtimit t\u00eb thirrjeve ioctl n\u00eb drejtuesin vendas NVIDIA dhe pun\u00ebs n\u00eb nivelin ABI t\u00eb drejtuesit NVIDIA, pa p\u00ebrkthimin e k\u00ebrkesave n\u00eb nivelin API.

N\u00eb sistemin e mysafir\u00ebve ngarkohet nj\u00eb modul b\u00ebrthamor, i cili ofron skedar\u00ebt e pajisjeve \/dev\/nvidiactl, \/dev\/nvidia0\u2026N, \/dev\/nvidia-uvm dhe kalon k\u00ebrkesat ioctl() dhe mmap() p\u00ebrmes virtqueue tek procesori n\u00eb mjedisin e prit\u00ebsit, i cili i d\u00ebrgon ato drejt drejtuesit t\u00eb prit\u00ebsit NVIDIA.

N\u00eb dallim nga kalimi ekskluziv i qasjes n\u00eb GPU (VFIO Passthrough), projekti virtio-nvgpu siguron qasje t\u00eb p\u00ebrbashk\u00ebt n\u00eb nj\u00eb GPU nga disa makinat virtuale<\/a>, dhe n\u00eb krahasim me virtio-gpu (Venus, VirGL) funksionon p\u00ebrmes kalimit ABI n\u00eb drejtuesin NVIDIA, e jo n\u00eb nivelin e p\u00ebrkthimit t\u00eb API grafike Vulkan dhe OpenGL. Disavantazhet e virtio-nvgpu jan\u00eb mungesa e izolimit t\u00eb plot\u00eb mbi baz\u00ebn e IOMMU (sistemet mysafir punojn\u00eb p\u00ebrmes drejtuesit host t\u00eb NVIDIA dhe kufizohen vet\u00ebm n\u00eb filtrimin e thirrjeve ioctl) dhe var\u00ebsia nga ABI e drejtuesve NVIDIA (ABI ndryshon me \u00e7do version dhe k\u00ebrkon adaptimin e virtio-nvgpu). <\/p>\n Kapacitetet e virtio-nvgpu jan\u00eb t\u00eb mjaftueshme p\u00ebr renderimin, kodimin e videove dhe llogaritjet duke p\u00ebrdorur API-n\u00eb Vulkan, OpenGL, NVENC dhe CUDA.
