Ma\u00edra Canal von Igalia hat ein Projekt zur Neuschreibung des VGEM (Virtual GEM Provider) Treibers in Rust vorgestellt. VGEM umfasst etwa 400 Codezeilen und bietet ein hardwareunabh\u00e4ngiges Backend f\u00fcr GEM (Graphics Execution Manager), das f\u00fcr den gemeinsamen Zugriff auf die Puffer von Treibern f\u00fcr Software-3D-Ger\u00e4te wie LLVMpipe verwendet wird, um die Leistung der Software-Rasterisierung zu verbessern. <\/p>\n

VGEM wird der zweite grafische Treiber in Rust sein, der auf Kernel-Ebene arbeitet (der erste war der DRM-Treiber (Direct Rendering Manager) Asahi f\u00fcr die GPU Apple AGX, die in Apple M1\/M2-Chips verwendet wird). Bei der Entwicklung war es notwendig, neue Bindungen zu schaffen, um aus Rust-Code mit der Plattformhardware, dem XArray-Typ und den mit dem direkten Zugriff auf den Speicher verbundenen Abstraktionen, wie z.B. DMA-Barrieren (DMA fences), zu arbeiten. In der aktuellen Entwicklungsphase ist der Treiber nahezu fertig, hat die meisten IGT-Tests bestanden, mit Ausnahme von zwei Pr\u00fcfungen (vgem_slow und vgem_basic@unload), ben\u00f6tigt jedoch noch Unterst\u00fctzung f\u00fcr IOCTL.
