A Complex Emulation Stack
Asahi Linux's innovative approach involves a sophisticated emulation stack comprising four translation layers:
- FEX: Emulates x86 instructions for ARM hardware
- Wine: Translates Windows code to Linux
- DVK and Proton: Convert DirectX API calls to Vulkan
This intricate system overcomes the challenges of running x86 Windows games on ARM-based Apple Silicon, making Asahi Linux the world's first Linux distribution to accomplish this feat.
Overcoming Technical Hurdles
The Asahi team faced several technical challenges, including:
- Page size differences : Apple systems use 16K page sizes, while Windows x86 games expect 4K pages. To address this, Asahi developers implemented a virtualized secondary ARM Linux kernel with a different page size.
- Memory management : The emulation overhead requires at least 16GB of system memory for the most demanding games.
- Graphics API translation : Converting DirectX calls to Vulkan presented significant challenges, which the team is actively working to resolve.
Current State and Future Prospects
While still in the alpha stage, Asahi Linux's x86 Windows compatibility has already shown impressive results:
- Playable titles : Cyberpunk 2077, Hollow Knight, Portal 2, Fallout 4, and Control
- Performance : Many indie games run at full speed, while more demanding titles are playable but may not yet achieve 60 FPS
The developers are working towards a 1.0 release, with ongoing efforts to improve compatibility and performance. One notable achievement is the Honeycrisp driver, the first conformant driver for M1 silicon across any operating system.
