I have a derivation for FEX 2408 with working tests over here, if you wanted to use that for reference: https://github.com/Liamolucko/nix-config/blob/31ae4e3240addc81fd79afb4344050619f639813/pkgs/fex/default.nix |

Oh, nice! I unfortunately couldn't finish the tests on the day of making the PR and didn't have much time to work on this recently, hence I marked it as draft. But I'll try to integrate the tests now from your branch and see how it goes. |

I think for now I will not add tests, as they cause build failures on kernels with 16k page size. |

Adds FEX, a fast usermode x86 and x86-64 emulator for Arm64 Linux.
NOTE: When compiling with tests (
doCheck = true), FEX requires a kernel with 4k page size. So this means, e.g. running it directly on something like the 16k page size Asahi kernel won't work (it will cause a<jemalloc>: Unsupported system page sizeerror when compiling). So for testing I used an aarch64 virtual machine.Things done
