v1.0

  • The kernel can run on real hardware. I have tested this on Starfive Visionfive 2 v1.3B.
  • The kernel takes care of SMP more gracefully (by explicitely forbidding more than one hart running at the same time).
  • The kernel has been stripped down from unneeded complexity.

State of the project by the end of SUSE Hackweek 2024

As part of SUSE Hack Week 24 I started this project with the scope in mind to at least have something running. This is what I have achieved by the end of this week:

  • The kernel knows how to parse the Device Tree blob to obtain the memory location of the initrd blob.
  • The kernel can parse the initrd (as referenced by the Device Tree blob) to reference all the user-space binaries.
  • The kernel can parse the ELF binary for each user-space binary in order to get their binary entry.
  • The kernel can react to the OpenSBI timer and count seconds on QEMU.
  • The kernel can schedule each binary entry depending on the requirement of the whole system.

Hence, by the end of the week I already got a kernel that could start on QEMU and show the whole fizz, buzz, fizzbuzz strings as given by user-space processes. Even with rough edges still to be polished, my initial goals have been met.
