[mx]

Update (2019-02-06): rewrite six, [nx], can be found here.

---

The fifth rewrite of what never was, OrionOS. As of version 0.9.0, [mx] has surpassed Orion-X4 in its featureset.

Disclaimer

[mx] often faces stretches of active development followed by complete abandonment. This project will never die (only rewritten), fear not.

Current Features

• Long mode (x86-64) + Higher Half, thanks to [fx] loader.
• BGA Support, works in QEMU, VirtualBox and Bochs.
• Working IPC system -> rewrite in progress
• Basic networking support (DHCP, DNS, IPv4, TCP/UDP)
• Somewhat complete libc written
• New in 0.8.2: [fx] loader! Now loads the [mx] kernel (as a GRUB module)... it's basically a stripped down version of Orion-X3/4 TBH.
• Also new in 0.8.2: [mx] runs in Bochs!

TODO List

High Priority

• execve() and family
• Stabilty fixes here and there -- it's gotten much better now
• HPET Support

Low Priority

• APIC Stuff, including IOAPIC/LAPIC
• Startup an AP CPU for fun?
• Fix the StandardIO implementation in Iris -- it's fugly (and broken)
• Finish pthreads beyond basic stuff

Trying out [mx]

Required Software ####

• QEMU
• C++ compiler (that targets your own platform)
• Clang is optional but highly recommended.
• Sudo access if you're on Linux, not necessary on OS X. Windows not supported (ATM, or ever)

Building [mx]'s toolchain

• Run the ./bootstrap script (you may have to chmod +x it first. Rest assured it's not malicious :P)
• Everything will be done automatically -- you will need to enter some commands (guided) into QEMU to install GRUB.
• It will take a long time -- the script will first clone patched versions of GNU Binutils and GCC.
• It will then proceed to build these, along with GNU's libstdc++ as well as [mx]'s homegrown libc (the former taking a much longer time)

Building the kernel

• Once the bootstrap script is done, you should be able to run 'make' in the root directory and have it run.

• If it does not, report an issue on Github.

• Note: if you are not using Clang++ to compile the kernel, you can use the toolchain you just built (found in build/toolchain)

• You will have to modify the CXXFLAGS variable in the makefile to fit GCC instead of Clang. One day I'll patch clang to target this.

• One day.
