This uses the Rockchip RK3588 SoC with an ARM Mali-G610 GPU. In general, that's a nice chip. My concerns are - are there open source (Linux) drivers for that GPU available now? - is this CPU really suited for battery-powered mobile app

Are you planning to also provide an English translation of your microkernel book? That sounds very interesting...

Virtio is not qemu only. For example, the macOS virtualization framework on Apple Silicon Macs (and x86 machines IIRC) also provides virtio devices, other hypervisors. An overview of the available devices can be found in this presentation:

Comer was also my introduction to OS design and I still like the approach used in his Xinu books. I had a quick glance at the OS in the linked article. This seems to be based on a 32-bit RISC-V with MMU. However, AFAIK, all available RISC-V

Not quite, the ST floppies were DD (double density). One problem that could occur is that low-end ST configurations - especially the 260ST - were delivered with a single sided floppy drive (SF354, 1 side, 80 tracks, 9 sectors of 512 byte pe

It would be interesting to learn more about the hardware and CPU platforms used - e.g. radiation hardened SPARC (Gaisler Leon-based?) or PowerPC systems - and if the source code for the satellite platforms' NetBSD port is available. Wh

No comment on your website, sorry - but at first glance I thought there was bad kerning ("keming") involved and your domain name is actually "pornostudy.io"... maybe a slight name variation would help to reduce that conf

Unfortunately, this thing still costs more than half the price of a basic M4 Mac Mini... Even though it looks a bit like the Arm-based Windows Dev Kit 2023 PCs (which the tomshardware article mentions) it seems to be based on some Intel CPU

Dupe, see https://news.ycombinator.com/item?id=42171124 As I mentioned in my comment to that article, the JH7110 is not an ideal platform for a mobile device, since suspend to RAM is not supported.

There is, but you have to select the M1 SoC to get it.

The 2014 Mac Minis were such a downgrade, the entry model was downgraded from a 2.5 GHz dual-core Ivy Bridge Core i5 (3210M) in the 2012 models to a 1.4 GHz dual-core Haswell Core i5 (4260U).

To add some details - the source code for QNX was available from 2007 until the takeover by RIM/Blackberry in 2010. So do you plan to offer access to QNX source code again in the future? https://www.qnx.com/news/pr
