Fwd: GNU Guix POWER9 OpenStack application (was: New POWER9 machines for the Guix build farm?)

Re: New POWER9 machines for the Guix build farm?
Hello, There is libre firmware being worked on, latest news say that it does work but some features are not implemented. I have not tested that firmware however. There is a contest organized by RaptorCS to liberate the firmware: https://www.raptorcs.com/TALOSII/nic_fw_contest.php And here's the ongoing work: https://github.com/meklort/bcm5719-fw https://wiki.raptorcs.com/wiki/BCM5719 An interesting thing to note is that 10Gbit network cards from the same vendor (Broadcom) are implemented fully with hardware ASICs and do not require firmware at all. So that's a work around to the problem. source: developer of the libre firmware. dftxbs3e On 11/29/19 1:50 PM, Marco van Hulten wrote: Hello— On 29 Nov 09:25 dftxbs3e wrote: I'm really happy to hear this!

Fantastic to see this work out! The other free modern architecture, RISC-V, is that like a sort of competitor of POWER9? Or is it more like Talos II being the obvious choice for a server (and workstation) because it is available now/more established? —Marco

It's good to hear this kind of positive experience about these new machines!

I own now a RaptorCS Blackbird[0] with an 8 core CPU and 32GiB RAM for half a year. I use it as my daily desktop driver. It runs openSUSE Tumblweed[1]. Setup was quite easy if you only want to use it as server without an GPU. You only need a long enough (ca 15cm) 4mm hex key to screw the fan on to the CPU. I could borrow mine. The rest of the installation and setup process wasn't that different from installing a x86 server. The nice thing is the openBMC chip, so remote management is quite nice :) All in all the biggest pain point for me, was getting the machine through the customs. But I heard from people in the EU who had a pretty smooth experience with that. I offer my help in the whole process (ordering, customs, setup, installation, maintenance). ~Jonathan P.S: It might be worth to ask RaptorCS and IBM, if they could give us some discounts.

I was curious the other day looking at multiarch compilation using the qemu-binfmt service, is there support for POWER PC? Anyways, I would love to see support for POWER9 come to Guix. I have limited experience with this architecture, but I will keep lurking in this thread. Good luck! -- Brett M. Gilio https://git.sr.ht/~brettgilio/
