OpenBSD 6.8 will be the first official release of OpenBSD/powerpc64.
And since there are always little bits missing, work is continuing...
Currently OpenBSD/powerpc64 only supports POWER9 processors and runs stably on PowerNV machines based on the Raptor Computing Systems Talos II and Blackbird boards. SMP is not yet supported. Support for POWER8 processors is planned but won't happen unless someone provides us access to suitable hardware.
OpenBSD/powerpc64 does not run under a hypervisor such as PowerVM or PowerKVM.
OpenBSD/powerpc64 is known to work on the following machines:
OpenBSD/powerpc64 is expected to run on IBM PowerNV systems as well. Please give it a try if you have access to such hardware.
Snapshots are made available from time to time, in this location as well as on a few mirrors. Here are the OpenBSD/powerpc64 snapshot installation instructions as well.
There are several types of installation media provided, so that OpenBSD/powerpc64 can be installed or upgraded via miniroot images as well as network installs.
The miniroot provides an easy installation environment. Just dump the miniroot to a USB flash drive with dd and insert it into a USB slot of the machine. After powering on the machine an OpenBSD install option should appear in the petitboot bootloader menu.
It is also possible to boot the OpenBSD/powerpc64 install environment directly from a HTTP or TFTP server.
