Ah, that explains this patchset that was submitted to the Linux kernel today
"KVM: s390: Introduce arm64 KVM"
"By introducing a novel virtualization acceleration for the ARM architecture on
s390 architecture, we aim to expand the platform's software ecosystem. This
initial patch series lays the groundwork by enabling KVM-accelerated ARM CPU
virtualization on s390....."

- rbanffy 6mo agoZ/OS for ARM then? ;-) I’ve been running VM/370 and MVS on my RPi cluster for a long time now.
- kraftverk_ 6mo agoCool, can you share more about the setup?
- rbanffy 6mo agoA 4x RPi Zero Ws Docker Swarm cluster running the dockerised versions of Hercules with VM/370 Sixpack, VM/370 CE and MVS TK 4. All in an IKEA picture frame.
- trebligdivad 6mo agoOh that's a weird way to do it; they used to have an x86 add on block for mainframes which was just a pile of x86 blades with some integration.
- bombcar 6mo agoI loved the era of "daughter cards" which were just entire computers on a board. things like https://www.youtube.com/watch?v=a6b4lYOI0GQ https://www.youtube.com/watch?v=a6b4lYOI0GQ could get you a really interesting form of multitasking

- Teever 6mo agoThat's what I was hoping Apple was going to do with a refreshed Mac Pro. I had envisoned a smaller tower design that with PCI slots and Apple developing and selling daughter cards that were basically just a redesigned macbook pro PCB but with a PCI-E edge connector and power connector. The way I see it a user could start with a reasonably powerful base machine and then upgrade it over time and mix and match different daughter cards. A ten year old desktop is fine as a day to day driver, it just needs some fancy NPU to do fancy AI stuff. This kind of architecture seems to make sense to me in an age where computers have such a longer usable lifespan and where so many features are integrated into the motherboard.

- Grosvenor 6mo agoApple already experimented with this with the prototype Jonathan computer. It's very late 80's in its aesthetic, and I love it. https://512pixels.net/2024/03/apple-jonathan-modular-concept/ https://512pixels.net/2024/03/apple-jonathan-modular-concept...
- raverbashing 6mo agoBut I wonder if this is "much better" than x86 emulation or virt? Is there really SW that's limited to (Linux) ARM and not x86?
- Jarwain 6mo agoTechnically aren't most android apps limited to ARM?
- toast0 6mo agoThere's certainly some, but I don't think most. I'd guess most apps are bytecode only, which will run on any platform. Some apps with native code have bytecode fallbacks. Many apps with native code include multiple support for multiple architectures; the app developer will pick what they think is relevant for their users, but mips and x86 are options. There were production x86 androids for a few years, some of those might still be in user bases; mips got taken out of the Native Development Kit in 2018 so probably not very relevant anymore.
- MikePlacid 6mo ago> Is there really SW that's limited to (Linux) ARM and not x86? MacOS? (hides)
- wmf 6mo agoProbably Intel and AMD aren't willing to do this deal but Arm is.
