Tra l'altro, l'emulatore FEX \u00e8 utilizzato dal progetto Asahi per facilitare l'esecuzione in ambienti Linux su sistemi con chip ARM Apple Silicon, di giochi del catalogo Steam compilati per l'architettura x86_64. Il codice del progetto \u00e8 scritto in C++ con inserimenti in assembly ed \u00e8 distribuito con licenza MIT.    <\/p>\n<p>Le librerie necessarie per eseguire applicazioni x86 in un ambiente ARM64 vengono collegate sotto forma di overlay con un'immagine del file system radice (rootfs), fornita in formato squashfs. Tale overlay consente di evitare la creazione di un ambiente chroot separato. Il caricamento delle immagini rootfs gi\u00e0 formate dal progetto avviene tramite un'utilit\u00e0 appositamente preparata chiamata FEXRootFSFetcher.    <\/p>\n<p>Per consentire l'accesso a determinate funzionalit\u00e0 dell'ambiente host, come gli strumenti per gestire audio e grafica 3D, nella rootfs vengono inserite librerie thunk speciali, che traducono le chiamate a librerie e codice sul lato del sistema host (ad esempio, le chiamate a OpenGL e Vulkan possono essere reindirizzate). Tali librerie possono anche essere utilizzate sul lato host per accedere al codice nell'ambiente ospite. Tra le librerie disponibili per il passthrough ci sono: libEGL, libGL, libSDL2, libX11, libVDSO, libasound, libdrm, libfex_malloc, libvulkan, libwayland-client e libxshmfence.    <\/p>\n<p>Tra le novit\u00e0 della nuova versione, si segnala la risoluzione dei problemi con l'avvio del client Steam, la transizione dall'emulazione dell'istruzione x86 PAUSE all'uso dell'istruzione ARM WFE al posto di YIELD, il supporto per l'emulazione delle chiamate di sistema necessarie per l'uso dei controller, il miglioramento dell'emulazione CPUID e RDTSCP, la ristrutturazione di FEXCore (backend di emulazione CPU) e la risoluzione di difetti nell'emulazione delle estensioni AVX.<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
