Initiativet for at implementere st\u00f8tte for Apple's M1-chip i Linux, fremmet af projekterne Asahi Linux og Corellium, har n\u00e5et et punkt, hvor det er muligt at k\u00f8re GNOME-desktoppen i et Linux-milj\u00f8 p\u00e5 et system med en Apple M1-chip. Visningen er organiseret via framebuffer, og OpenGL-support er sikret ved hj\u00e6lp af den softwarebaserede rasterisator LLVMPipe. N\u00e6ste skridt vil v\u00e6re at involvere display-coprocessoren for output med op til 4K opl\u00f8sning, som der allerede er udf\u00f8rt reverse engineering af driverne til. <\/p>\n

Projektet Asahi har opn\u00e5et inklusion af basal underst\u00f8ttelse af M1 SoC-komponenter, der ikke er relateret til GPU, i Linux-kernen. I det demonstrerede Linux-milj\u00f8 er der anvendt flere ekstra patches ud over de funktioner, der findes i den standard kerne, relateret til PCIe, pinctrl-driveren til den interne bus og display-driveren. Disse tilf\u00f8jelser har gjort det muligt at f\u00e5 output til sk\u00e6rmen og f\u00e5 USB og Ethernet til at fungere. Grafikaccelerationen bruges dog endnu ikke. <\/p>\n

Det er interessant, at for reverse engineering af M1 SoC har Asahi-projektet i stedet for at fors\u00f8ge at disassemblere macOS-driverne implementeret en hypervisor, der k\u00f8rer i niveauet mellem macOS og M1-chippen og i et transparent mode fanger og logger alle operationer med chippen. Blandt de tr\u00e6k ved M1 SoC, som besv\u00e6rligg\u00f8r underst\u00f8ttelsen i tredjeparts OS, n\u00e6vnes tilf\u00f8jelsen af en coprocessor til displaycontrolleren (DCP). Halvdelen af funktionen fra macOS-displaydriveren er blevet flyttet til denne coprocessor, som kalder de tilg\u00e6ngelige funktioner fra coprocessoren gennem et specielt RPC-interface. <\/p>\n

Entusiaster har allerede analyseret tilstr\u00e6kkeligt mange udfordringer med denne RPC-gr\u00e6nseflade til at aktivere co-processoren til sk\u00e6rmoutput, samt til at styre hardwaremark\u00f8ren og udf\u00f8re kompositions- og skaleringsoperationer. Problemet er, at RPC-gr\u00e6nsefladen afh\u00e6nger af firmware og \u00e6ndres i hver version af macOS, derfor planl\u00e6gger Asahi Linux kun at implementere support for bestemte firmwareversioner. F\u00f8rst og fremmest vil der blive sikret support for den firmware, der f\u00f8lger med macOS 12 \u201eMonterey\u201c. Det er ikke muligt at downloade den n\u00f8dvendige firmware, da firmware installeres af iBoot p\u00e5 stadiet f\u00f8r kontroloverdragelsen til operativsystemet og verificeres med en digital signatur.
