The Talos II is a dual socket Power 9 motherboard from Raptor Computing Systems. It features opensource firmware and openBMC.

Hardware

Standard

Device Make/model Status Vendor ID / Product ID Kernel driver(s) Kernel version Notes
CPU IBM Power 9 Works N/A N/A 4.17.12 Requires kernel version 4.16+, ideally 4.17+. Also benefits from very recent gcc releases.
Video card ASpeed Graphics Works 1a03:2000 ast 4.17.12 Kernel driver works without issue. xf86-video-ast has build issues, xf86-video-modesetting works fine with glamor disabled.

Installation

The system uses petitboot as main bootloader. The grub based ppc64le install media iso contents can be copied to a partition of an usb storage and used.

Make sure to pass console=hvc0 as boot argument if you are using the OpenBMC console.

OpenBMC

The openbmc will ask for an address if the first Ethernet port is connected. It would listen to port 22 and port 2200. Petitboot will be directly reachable from port 2200.

Kernel

Use powernv_defconfig.

To enable hardware accelerated virtualization:

KERNEL Enable hardware virtualization, kvm_hv
--- Virtualization
<M>   KVM support for PowerPC book3s_64 processors
<M>     KVM for POWER7 and later using hypervisor mode in host
< >     KVM support without using hypervisor mode in host

Configuration

Bootloader

The Talos uses petitboot as part of its firmware and bootloader. This means there is no need to install grub/yaboot/etc, as all petitboot needs is the config file. kboot has a delightfully simple config format, which is easily written.
