A fost lansat\u0103 versiunea proiectului FEX 2412, care dezvolt\u0103 un emulator pentru a rula jocuri \u0219i aplica\u021bii compilate pentru arhitecturile x86 \u0219i x86-64, \u00een medii Linux pe sisteme cu procesoare ARM64 (AArch64). Printre altele, emulatorul FEX este utilizat de proiectul Asahi pentru a organiza lansarea \u00een medii Linux care func\u021bioneaz\u0103 pe sisteme cu procesoare ARM Apple Silicon, a jocurilor din catalogul Steam, compilate pentru arhitectura x86_64. Codul proiectului este scris \u00een C++ cu inser\u021bii Assembly \u0219i este distribuit sub licen\u021ba MIT. <\/p>\n

Bibliotecile necesare pentru a rula aplica\u021bii x86 \u00een medii ARM64 sunt conectate sub form\u0103 de overlay peste imaginea sistemului de fi\u0219iere r\u0103d\u0103cin\u0103 (rootfs), furnizat\u0103 \u00een format squashfs. O astfel de strat permite evitarea cre\u0103rii unui mediu chroot separat. \u00cenc\u0103rcarea imaginilor rootfs deja formate de proiect se face printr-o utilitar\u0103 special preg\u0103tit\u0103, FEXRootFSFetcher. <\/p>\n

Pentru a organiza accesul la anumite func\u021bionalit\u0103\u021bi ale mediului gazd\u0103, cum ar fi instrumentele pentru lucrul cu sunetul \u0219i grafic\u0103 3D, \u00een rootfs sunt plasate biblioteci thunk speciale, care traduc apelurile c\u0103tre biblioteci \u0219i cod pe partea sistemului gazd\u0103 (de exemplu, apelurile c\u0103tre OpenGL \u0219i Vulkan pot fi redirec\u021bionate). Aceste biblioteci pot fi utilizate \u0219i pe partea gazd\u0103 pentru a accesa codul din mediul oaspete. Printre bibliotecile disponibile pentru redirec\u021bionare se num\u0103r\u0103: libEGL, libGL, libSDL2, libX11, libVDSO, libasound, libdrm, libfex_malloc, libvulkan, libwayland-client \u0219i libxshmfence. <\/p>\n

Printre modific\u0103rile din noua versiune se num\u0103r\u0103 solu\u021bionarea problemelor cu lansarea clientului Steam, trecerea emul\u0103rii instruc\u021biunii x86 PAUSE la utilizarea instruc\u021biei ARM WFE \u00een loc de YIELD, asigurarea emul\u0103rii apelurilor de sistem necesare pentru a lucra cu gamepad-uri, \u00eembun\u0103t\u0103\u021birea emul\u0103rii CPUID \u0219i RDTSCP, restructurarea FEXCore (backend-ul emul\u0103rii CPU), corectarea defectelor \u00een emularea extensiilor AVX.
