Coded from scratch by Ron Shabi, mainly to learn the architecture.
- Globally usable, buffered
printk - Exception handler
- KSyms with an
addr2line-like interface and unwind support - GICv3 Support
- Virtual timer IRQ
The Vortex kernel currently compiles with GCC 14.2 for the aarch64-none-elf triplet. Other compilers were not tested, although will probably work, since the code is fairly simple and doesn't use any weird C extensions.
The only tested boad is QEMU's virt for the Cortex-A72. I currently don't plan on implementing more boards/configurations.
See scripts/qemu.sh for specific configuration.
Just make :)
Running make qemu will compile and run the kernel in QEMU
Note that the build is an out of tree build, such that all objects files, generated code and ELFs reside in build which is created by Make.
