Hi,
I successfully ported SqueakNOS to Pharo, and want to share it with you!
It works with Pharo 4.0 image, networking included, ping works!
What is different:
- I use my own CMake build file, with "out-of-tree" build support, instead of "build.xyz" directories inside source tree + some template scripts to build any VM type, but it is not complete...
- I use MUSL instead of GlibC, cross-compiling GlibC statically on 64bit for 32bit seems impossible, but anyway I use 32bit environment to build it
- It works with pre-opensmalltalk-vm migration directory structure, so the "sync" with latest trunk remains #TODO, or maybe start a new branch again from the latest upstream commit should work too
- freetype is included, but will not load any fonts, since the filesystem driver is image-side... so you will need to make new fonts embedded, if you want them
- known issues: image snapshot and fileout are not working, current date+time hacked to make fat32 timestamps work
- revision needed: timer (heartbeat) vs. GC vs. interrupts enable/disable
- there are even some hacks to image-side methods
PharoNOS platform directory sources: [pharonos branch]
SRC: https://gitlab.com/johnnyzz/pharonos
VM sources: [dev branch]
SRC: https://gitlab.com/johnnyzz/pharo-vm
- added platform directory, build scripts and CMake templates
- added VMMaker configs
Build Environment (32bit) - Docker image repository, with CI:
https://gitlab.com/johnnyzz/dev-build
PharoNOS CI (uses previous Docker image):
CI: https://gitlab.com/johnnyzz/pharo-nos-build
How to run it:
You can download fresh disk image from CI and then run:
(sudo) kvm -hda build/NOS.img -enable-kvm -cpu kvm32 -vga qxl -m 256 -netdev tap,id=user.3,ifname=tap2,vhost=on -net nic,model=rtl8139,netdev=user. 3 -global isa-fdc.driveA= -serial stdio
One more thing:
Statically linked Pharo Spur32 (headless) VM, with only one dependency - Linux kernel:
CI: https://gitlab.com/johnnyzz/pharo-build-static
Size: 2,4MB (too big?, but Freetype included too!)
enjoy
