HelinKern

just new implementation of my old osdev project. Many components are based on open source implementation, check the files for more information.

Sources

The kernel uses source code and/or the design from there projects:

• SOSO OS
• ToaruOS
• cuteOS
• JamesMolloy osdev
• BrokenThorn osdev
• My old osdev project
• At some point ReactOS
• And many many others projects(all there repos just named as osdev)
• OSDEV wiki
• GRUB(module loading,AHCI and many many other thinks)

  See also

  See also there projects and their branches that i used to make the version:

• SOSO OS
• ToaruOS
• cuteOS
• Project where you can find USB,SATA,PCI realization and many more are here
• ReactOS
• Used GRUB

  Build

  To build you need to install there software(Debian):

• sudo apt install gcc nasm xorriso grub-common grub-pc-bin make qemu-system-i386 gdb -y

Then change cross-compiler path in Makefile(you can leave it empty, so it can be compiled with system tools)

Then do there commands:

# This commands will generate the X86 image. To generate X86_64 image do: ```mv Makefile Makefile_x86 && mv Makefile_x86_64 Makefile && make```
gcc scripts/sym_exp.c -o scripts/smexp -lelf # Before doing this command install libelf headers.
cd scripts && ./smexp && cd ..
make # Build project
make makeiso # Make ISO
make run # Run via QEMU

System Requirements

• 486+ CPU for base system, Pentium Pro+ for newlib applications
• 20M of memory to boot base system
• If the system doesn't boot in graphical mode, then disable UI mode here, and set dontFB here to true and the system must boot in VGA text mode

  For X86_64:

  • Minimum 256M of RAM.
  • Any x86_64 compatable CPU.

Userland

See this file

Current goals

• Implement all POSIX functions defined in the specifications. While many functions are just defines, they will be implemented as soon as possible.

  Supported architectures:

• x86(main project architecture)
• RISC-V(planned, interrupts implemented, MMU and context switch is required)
• x86_64(first 64 bit port for kernel, have some perfomence issues in FB driver, also need to build the userland toolchain yourself)
