Blackbird / Re: How to implement Secure Boot on the Blackbird
« on: September 27, 2020, 01:47:09 pm »
FWIW, there is a wiki page about it: https://wiki.raptorcs.com/wiki/Secure_Boot_with_your_own_keys

But I have not tried it myself.

Blackbird / Re: How's the FlexVer connector used?

FlexVer modules for Raptor's POWER9 platforms are (at least publically) not available yet...

Firmware / Re: How to setup Secure Boot with PetitBoot
« on: May 03, 2020, 09:52:07 am »
Recently someone on IRC got secure boot working on their Blackbird and posted instructions on the wiki: https://wiki.raptorcs.com/wiki/Secure_Boot_with_your_own_keys

But it's not... "plug and play", you have to recompile the firmware at least two times if I remember correctly.

I have not yet experienced the problem myself (though I also run NVMe SSDs in my system), but I can tell you that zdykstra and q66 in the IRC channel (#talos-workstation) have experienced similar issues.

Blackbird / Re: Heatsink dual fan configuration
« on: December 17, 2019, 04:26:42 pm »
I think that depends on the fans you are using in combination with the firmware.

AFAIK the reason the dual fan mod using two Noctua NF-A9 PWM fans doesn't work on the Blackbird is that it uses a newer firmware than the Talos II. See also the point:
Quote
note, on firmware 04-16-2019 dual-fan mod no longer works reliably, as new less agressive profiles spin down fans below minimum speed and opembmc print a lot of warnings about CPU0 fan being inoperational. fan still spins, but fails every 10 seconds, spins up and fails again endlessly. refer to Fan Tuning page for a fix.
from https://wiki.raptorcs.com/wiki/Dual_92mm_fan_CPU

As explained in the Fan Tuning page, you can adjust the parameters in OpenBMC to make it work.

I suppose you could also use !BMC (https://git.anastas.io/dormito/br-blackbird-external) in place of OpenBMC, where you can configure the fan settings more easily (AFAIK you need to recompile it to update fan the settings, but compilation takes less time and the fan daemon infrastructure is simpler).

Howdy! Glad to see the party move outside of Twitter.
