I may have gotten carried away. - I missed some stuff for end parenthesis because I accidentally searched within project files instead of the entire directory (so some thunk/test/windows stuff was missed), cleaned those up. - `INTERFACE`, `PUBLIC`, `PRIVATE`, `RUNTIME`, `LIBRARY` should be on the same line as the target name. (I should really invest in making a style guide...) - Some short statements were unnecessarily split across multiple lines--cleaned those up - Made a common `LinkerGC` module that applies gc-sections etc. to a target in Release mode - Usually for functions you want to have something on the first line, e.g. `FILES`/`DIRECTORY` for install, or the target/a positional argument, etc etc. Not always though, notably for some custom_command calls TODO: - What's with the `list(APPEND LIBS...)` stuff? It's used really inconsistently, sometimes not at all, sometimes it looks like there're duplicates? A more thorough cleanup is in order there. Signed-off-by: crueter <crueter@eden-emu.dev>
FEX: Emulate x86 Programs on ARM64
FEX allows you to run x86 applications on ARM64 Linux devices, similar to qemu-user and box64. It offers broad compatibility with both 32-bit and 64-bit binaries, and it can be used alongside Wine/Proton to play Windows games.
It supports forwarding API calls to host system libraries like OpenGL or Vulkan to reduce emulation overhead. An experimental code cache helps minimize in-game stuttering as much as possible. Furthermore, a per-app configuration system allows tweaking performance per game, e.g. by skipping costly memory model emulation. We also provide a user-friendly FEXConfig GUI to explore and change these settings.
Prerequisites
FEX requires ARMv8.0+ hardware. It has been tested with the following Linux distributions, though others are likely to work as well:
- Arch Linux
- Fedora Linux
- openSUSE
- Ubuntu 22.04/24.04/24.10/25.04
An x86-64 RootFS is required and can be downloaded using our FEXRootFSFetcher tool for many distributions.
For other distributions you will need to generate your own RootFS (our wiki page might help).
Quick Start
For Ubuntu 22.04, 24.04, 24.10 and 25.04
Execute the following command in the terminal to install FEX through a PPA.
curl --silent https://raw.githubusercontent.com/FEX-Emu/FEX/main/Scripts/InstallFEX.py | python3
This command will walk you through installing FEX through a PPA, and downloading a RootFS for use with FEX.
For other Distributions
