Cutting edge XanMod kernel for WSL2, built with Clang ${{ needs.build.outputs.clang_version }} shipped by [archlinuxcn](https://github.com/archlinuxcn/repo). | |
Provide builds on different archs with matrix build utility of GitHub Action. | |
* `bzImage-x64v{2,3,4}` for generic-x86_64-v{2,3,4} | |
* `bzImage-skylake` for intel skylake | |
To check supported x86_64 level on your machine, see [how to check supported x86_64 level of the hardware](https://unix.stackexchange.com/questions/631217/how-do-i-check-if-my-cpu-supports-x86-64-v2?msclkid=42ca61e9aa7111ecbcab7bb1a4204357). | |
And if you happen to use intel skylake chips (just like me), you can choose `bzImage-skylake` for best tuning. | |
**NOTE for Win11**: the minimum requirement of Win11 ensures generic-x86_64-v3 support, so feel free to use `bzImage`. | |
