Inginerii de la Red Hat au propus pentru includerea \u00een nucleul Linux prima serie de patch-uri cu implementarea driverului Nova. Driverul este destinat utiliz\u0103rii cu GPU NVIDIA echipate cu firmware GSP, care sunt utilizate \u00eencep\u00e2nd cu seria NVIDIA GeForce RTX 2000 bazat\u0103 pe microarhitectura Turing. \u00cen aceste GPU, opera\u021biile de ini\u021bializare \u0219i gestionare sunt implementate \u00een firmware \u0219i sunt executate de un microcontroler GSP (GPU System Processor). Se preconizeaz\u0103 c\u0103, pe termen lung, Nova va \u00eenlocui driverul Nouveau pentru GPU-uri cu suport GSP. <\/p>\n

Noul driver este scris \u00een limbajul Rust \u0219i, av\u00e2nd \u00een vedere c\u0103 infrastructura pentru dezvoltarea driverelor Rust este \u00eenc\u0103 \u00een dezvoltare, codul Nova va fi transferat treptat \u00een nucleul principal, pe m\u0103sur\u0103 ce devin disponibile straturile necesare pentru limbajul Rust. \u00cen prima etap\u0103, pentru includerea \u00een nucleu, a fost propus driverul «nova-core», const\u00e2nd din 232 de linii de cod. Nova-core implementeaz\u0103 un nivel de baz\u0103 de abstrac\u021bie asupra interfe\u021belor de programare pentru firmware-urile GSP \u0219i ofer\u0103 un API independent de versiunile firmware-ului. <\/p>\n

\u00cen etapa urm\u0103toare, \u00een nucleu se pl\u0103nuie\u0219te includerea driverului DRM nova-drm (Direct Rendering Manager) pentru interac\u021biunea cu GPU-ul din spa\u021biul utilizatorului, precum \u0219i un driver VFIO cu manager pentru vGPU, care permite utilizarea GPU-urilor virtuale NVIDIA \u00een sistemele de virtualizare. <\/p>\n

Principala motivare pentru promovarea noului driver Nova este posibilitatea de a sc\u0103pa de complexit\u0103\u021bile asociate driverului Nouveau \u0219i de a ob\u021bine o simplificare semnificativ\u0103, datorit\u0103 utiliz\u0103rii handlerelor gata furnizate de firmware-ul GSP \u0219i eliminarea poverii suportului pentru GPU-uri mai vechi. Nova va permite, de asemenea, s\u0103 rezolve problemele arhitecturale care \u00een Nouveau necesit\u0103 o revizuire semnificativ\u0103 a codului, cum ar fi problemele de blocaj \u00een codul VMM\/MMU. Limbajul Rust a fost ales pentru a reduce probabilitatea apari\u021biei erorilor \u00een gestionarea memoriei, precum \u0219i ca o oportunitate de a combina munca la driverul de produc\u021bie cu crearea leg\u0103turilor \u0219i abstrac\u021biilor pentru dezvoltarea driverelor \u00een Rust.

\u00cen ceea ce prive\u0219te progresul ad\u0103ug\u0103rii \u00een nucleul Linux a capacit\u0103\u021bilor pentru dezvoltarea driverelor \u00een limbajul Rust, \u00een ramura 6.14 au fost acceptate straturile Rust pentru PCI, platforme, Open Firmware, dispozitive simbolice \u0219i unele func\u021bii de intrare\/ie\u0219ire. Greg Kroah-Hartman, responsabil de suportul ramurii stabile a nucleului Linux, \u00een pull request-ul de actualizare a driverelor pentru nucleul 6.14, a caracterizat starea actual\u0103 ca «aproape preg\u0103tit\u0103 pentru scrierea unui driver real \u00een Rust».
