QSOE Development Blog

The second QSOE release, v0.2, is out.

v0.1 was a singular machine.

HFI BIOS version 1.3 has been released.

On the 2nd of July I made the first commit in a repository called fu740-bios.

For a few months there has been a compiler in my tree that I have said nothing about, and it has now done the one thing that made me want to write about it at last: it compiles the whole of QSOE/N — the Skimmer microkernel, taskman, the C library, the dyn…

Two things happen in this release, and they turn out to be the same thing seen from opposite ends.

The project of bringing up my GK-208 video card at the early boot stages turned out to be much bigger than originally envisioned — and the approach for accomplishing the goal had to change completely mid-course.

Since 2024 I've wanted one specific thing: a RISC-V board that feels like a real personal computer.

I came across an old post of mine on the comp.os.qnx newsgroup, dated August 7, 2003.

The first QSOE release, v0.1, is out.

The last post ended with QSOE/L still in the emulator, and the next job named in plain words: carry the image across to the Unmatched and find out which of my QEMU assumptions were lies.

The three QSOE/N posts ended with a promise — the other half of the umbrella, QSOE/L, the same userspace running on seL4.

Part 2 left QSOE/N as a working operating system that had only ever run in QEMU.

Part 1 ended with Skimmer at v0.5 — a sound microkernel with QNX-shape synchronous IPC, and nothing running on top of it.

This is the first of three posts tracing QSOE/N from its first commit to its first boot on real hardware.

It was the first of April, and work on QRV — my port of QNX to RISC-V — was in full swing.
