Daniel Almeida, care se ocup\u0103 cu dezvoltarea codec-urilor video la Collabora, a publicat pe lista de discu\u021bii a dezvoltatorilor nucleului Linux o prim\u0103 implementare a driverului Tyr pentru GPU ARM Mali, care utilizeaz\u0103 tehnologia CSF (Command Stream Frontend), precum Mali G310, G510 \u0219i G710. Codul driverului este scris \u00een Rust \u0219i con\u021bine pu\u021bin peste 600 de linii de cod. Lucr\u0103rile la driverul Tyr se desf\u0103\u0219oar\u0103 \u00een colaborare \u00eentre angaja\u021bii companiilor Collabora, Arm \u0219i Google. <\/p>\n

Ca baz\u0103 pentru crearea noului driver, au fost folosite componente ale driverului abstract rust_platform_driver \u0219i ale driverului Nova, dezvoltat pentru GPU NVIDIA, scris \u00een Rust \u0219i par\u021bial ad\u0103ugat \u00een nucleul 6.15. Func\u021bionalitatea pentru interac\u021biunea cu GPU Mali a fost portat\u0103 din driverul DRM existent Panthor (Direct Rendering Manager), scris \u00een limbajul C. uAPI-ul driverului Tyr este identic cu uAPI-ul driverului Panthor, ceea ce permite utilizarea componentelor existente din spa\u021biul utilizatorului. <\/p>\n

Tehnologia CSF, utilizat\u0103 \u00eencep\u00e2nd cu genera\u021bia 10 de GPU Mali, se remarc\u0103 prin externalizarea unor func\u021bii ale driverului pe partea de firmware \u0219i prin utilizarea unui nou model de organizare a execu\u021biei pe GPU. \u00cen GPU-urile cu interfa\u021ba CSF, \u00een locul modelului bazat pe trimiterea unei serii de lucr\u0103ri, se aplic\u0103 un model bazat pe fluxul de comenzi cu planificarea cozii de flux de comenzi pe partea de firmware. Pentru organizarea muncii planificatorului, \u00een GPU este integrat un microcontroler separat Cortex-M7, iar pentru executarea instruc\u021biunilor CSF este prev\u0103zut\u0103 o unitate special\u0103 de execu\u021bie a comenzii (Command Execution Unit). <\/p>\n

Func\u021bionalitatea Tyr este \u00een prezent inferioar\u0103 driverului Panthor, dar dezvoltatorii inten\u021bioneaz\u0103 s\u0103 reduc\u0103 treptat diferen\u021ba p\u00e2n\u0103 c\u00e2nd se va ajunge la paritatea \u00een capacit\u0103\u021bile driverelor. Func\u021biile lips\u0103 necesit\u0103 integrarea de noi abstrac\u021bii \u00een nucleu pentru a crea drivere \u00een Rust, astfel \u00eenc\u00e2t dezvoltarea driverului Tyr va fi sincronizat\u0103 cu ad\u0103ugarea acestor abstrac\u021bii \u00een nucleu. De exemplu, nucleul nu dispune \u00eenca de func\u021bionalit\u0103\u021bi pentru maparea memoriei \u00een driverele Rust pentru GPU, dezvoltate \u00eentr-un set de patch-uri GPUVM care nu a fost \u00eenc\u0103 acceptat.
