Dezvoltatorii proiectului Mesa au anun\u021bat certificarea driverului rusticl de c\u0103tre organiza\u021bia Khronos, care a trecut cu succes toate testele din setul CTS (Kronos Conformance Test Suite) \u0219i a fost recunoscut ca fiind complet compatibil cu specifica\u021bia OpenCL 3.0, ce define\u0219te API-ul \u0219i extensiile limbajului C pentru organizarea calculului paralel multiplataform\u0103. Ob\u021binerea certificatului ofer\u0103 posibilitatea de a declara oficial compatibilitatea cu standardele \u0219i de a utiliza m\u0103rcile comerciale asociate cu Khronos. Verificarea a fost efectuat\u0103 pe un sistem cu GPU-uri integrate Intel de genera\u021bia a 12-a, folosind driverul Gallium3D Iris. <\/p>\n

Driverul este scris \u00een limbajul Rust \u0219i este dezvoltat de Karol Herbst de la compania Red Hat, care particip\u0103 la dezvoltarea Mesa, driverului Nouveau \u0219i a stivei deschise OpenCL. Rusticl serve\u0219te ca un echivalent al front-end-ului OpenCL Clover existent \u00een Mesa \u0219i este de asemenea dezvoltat folosind interfa\u021ba Gallium furnizat\u0103 \u00een Mesa. Clover se afl\u0103 \u00eentr-o stare de abandon de mult timp, iar rusticl este pozi\u021bionat ca \u00eenlocuitorul s\u0103u viitor. Pe l\u00e2ng\u0103 realizarea compatibilit\u0103\u021bii cu OpenCL 3.0, proiectul Rusticl se distinge de Clover prin suportul extensiilor OpenCL pentru procesarea imaginilor, dar \u00een prezent nu suport\u0103 formatul FP16. Pentru generarea binding-urilor pentru Mesa \u0219i OpenCL, care permit apelarea func\u021biilor Rust din cod C \u0219i viceversa, rust-bindgen este folosit \u00een Rusticl. <\/p>\n

Codul pentru suportul limbajului Rust \u0219i driverul rusticl a fost acceptat \u00een compunerea principal\u0103 a Mesa \u0219i va fi disponibil \u00een versiunea Mesa 22.3, care este a\u0219teptat\u0103 la sf\u00e2r\u0219itul lunii noiembrie. Suportul pentru Rust \u0219i rusticl va fi dezactivat \u00een mod implicit \u0219i va necesita o compilare cu specificarea explicit\u0103 a op\u021biunilor «-D gallium-rusticl=true -Dllvm=enabled -Drust_std=2021». La compilare, vor fi necesare ca dependen\u021be suplimentare compilatorul rustc, generatorul de leg\u0103turi bindgen, LLVM, uneltele SPIRV-Tools \u0219i transcriptorul SPIRV-LLVM-Translator. <\/p>\n

Discu\u021bia privind utilizarea limbajului Rust \u00een proiectul Mesa a \u00eenceput \u00een 2020. Printre avantajele suportului pentru Rust se num\u0103r\u0103 cre\u0219terea securit\u0103\u021bii \u0219i calit\u0103\u021bii driverelor prin eliminarea problemelor tipice legate de gestionarea memoriei, precum \u0219i posibilitatea de a integra \u00een Mesa contribu\u021bii externe, cum ar fi Kazan (implementarea Vulkan \u00een Rust). Printre dezavantaje se num\u0103r\u0103 complexitatea sporit\u0103 a sistemului de construire, reticen\u021ba de a se lega de sistemul de pachete cargo, extinderea cerin\u021belor pentru medii de construc\u021bie \u0219i necesitatea includerii compilatorului Rust \u00een dependen\u021bele necesare pentru construirea componentelor cheie ale desktop-ului \u00een Linux. <\/p>\n

De asemenea, merit\u0103 men\u021bionat c\u0103 s-au f\u0103cut progrese \u00een dezvoltarea driverului Nouveau, realizate de Carol Herbst. \u00cen driverul Nouveau a fost ad\u0103ugat suport de baz\u0103 pentru OpenGL pentru GNU NVIDIA GeForce RTX 30xx, bazat pe microarhitectura Ampere, lansate din mai 2020. Modific\u0103rile legate de suportul pentru noile cipuri vor fi incluse \u00een nucleul Linux 6.2 \u0219i Mesa 22.3.
