Red Hat'i insenerid on esitanud esimese pat\u0161ide komplekti, et lisada Nova draiver Linuxi tuumasse. Draiver on m\u00f5eldud NVIDIA GPU-dele, mis on varustatud GSP-firmware'iga, mida kasutatakse alates NVIDIA GeForce RTX 2000 seeriast, mis p\u00f5hineb Turingi mikroskeemiplatvormil. Sellistes GPU-des on initsialiseerimise ja haldamise toimingud rakendatud tarkvarafirmwares ja neid teostab eraldi mikrokontroller GSP (GPU System Processor). Eeldatakse, et pikaajalises perspektiivis asendab Nova draiver Nouveau draiverit GSP toega GPU-dele. <\/p>\n

Uus draiver on kirjutatud keeles Rust ja kuna Rust-draiverite arendamiseks vajalik infrastruktuur alles areneb, on Nova koodi kava j\u00e4rk-j\u00e4rgult tuua p\u00f5hiyhiku tuumikusse, kui vajalikud Rust-koodi \u00fcmbermitte seadmed muutuvad k\u00e4ttesaadavaks. Esimeses etapis on tuumikusse lisamiseks ettepanekus draiver \"nova-core\", mis koosneb 232 reast koodist. Nova-core rakendab p\u00f5hit\u00f5endid abstraktsioonide tasemel GSP tarkvaraliideste \u00fcle ja pakub API-d, mis ei s\u00f5ltu tarkvaraversioonidest. <\/p>\n

J\u00e4rgmises etapis on plaanis lisada tuumasse DRM-draiver nova-drm (Direct Rendering Manager), et suhelda GPU-dega kasutajaruumi kaudu, samuti VFIO-draiver virtuaal GPU hald\u00fcriga, mis v\u00f5imaldab NVIDIA virtuaalsete GPU-de kasutamist virtualiseerimiss\u00fcsteemides. <\/p>\n

Uue Nova draiveri edendamise peamiseks p\u00f5hjuseks on v\u00f5imalus vabaneda Nouveau draiveriga seotud keerukustest ja saavutada m\u00e4rkimisv\u00e4\u00e4rne lihtsustus, kasutades GSP-firmware'i pakutavaid valmis t\u00f6\u00f6tlejaid ning loobudes vanade GPU-de toe raskusest. Nova aitab samuti lahendada arhitektuurilisi probleeme, mis Nouveau-s vajavad koodibaasi olulist \u00fcmbertegemist, n\u00e4iteks probleemid VMM\\\/MMU koodi lukustustes. Rust'i keelt on valitud, et v\u00e4hendada m\u00e4luhaldusvigade tekkimise t\u00f5en\u00e4osust ning luua v\u00f5imalus t\u00f6\u00f6tada t\u00f6\u00f6tava draiveriga koos Rust'i draiverite jaoks m\u00f5eldud teede ja abstraktsioonide loomisega.

Mis puudutab progeressimist Rusti keele draiverite arendamise v\u00f5imaluste lisamisel Linuxi tuumikusse, siis 6.14 haru koostisosana on vastu v\u00f5etud Rust-i \u00fcmbermitmise seadmed PCI, platvormide, Open Firmware, s\u00fcmboolsete seadmete ja m\u00f5ningate sisendi\/v\u00e4ljundi funktsioonide jaoks. Greg Kroah-Hartman, kes vastutab Linuxi tuuma stabiilse haru toe eest, iseloomustas 6.14 tuuma draiverite uuendamise pull-request\u2019is praegust seisu kui \"peaaegu valmis reaalse Rusti draiveri kirjutamiseks.\"
