Greetings,
While I like the idea of SqueakNOS (Squeak on Bare Metal), having a
short life I prefer to work on value added.
The (old) idea being to use a "shim" OS which takes care of memory,
networking, USB drivers and which I do not have to support.
I basically develop on aarch64/arm64 chips, so naturally took a look at
revitalizing the framebuffer display: vm-display-fbdev.
Progress so far:
I can run both Cuis and Squeak images on Rasperry Pi 3 under Alpine
Linux, which is a very slim Linux using MUSL (vs libc) and busybox (vs
many separate commands). Both stack and Cog VMs run.
The VM _is_ the window system. You will need to build the VM.
If any intrepid explorers out there wish to help out or just take a
look, I have a repository with instructions and the fb-display-fbdev
code:

Also, the complete build tree for aarch64+MUSL+libevdev with updated
mvm's:

Bug reports (or better yet, fixes!) and help cleaning up the C code is
very much appreciated!
Enjoy!
