Linux Desktop on Apple Silicon/M1 in Practice

I bought M1 MacBook Air. It is the fastest computer I have, and I have been a GNOME/GNU/Linux user for long time. It is obvious conclusion that I need practical Linux desktop environment on Apple Silicon/M1.

Fortunately, Linux already works on Apple Silicon/M1. But how practical is it?

• Two native ports exist, but they don't have enough device support yet. It certainly takes some time.
  • Corellium https://corellium.com/blog/linux-m1
  • Asahi Linux https://asahilinux.org
• QEMU can run with Hypervisor.framework with:

Create template actions that's used to verify Go language pull requests before merging. It's easy to custom the flow, tools with your case.

Put pr_checker.yml or pr_checker_simple.yml to .github/workflows/ and see how it works with your pull requests. Make sure you are allows to use actions of Github.

• pr_checker.yml is using by mine with full checking tools. It will make sure every Go langauge pull requests will be buildable, testable, passed security checking and error-able code checking.
• pr_checker_simple.yml is more simpler with buildable, testable.
