Blackbird / Re: Blackbird Cooling

« on: November 16, 2022, 08:25:25 am »

There's an alternative firmware for the BMC on the Blackbird (maybe also Talos 2) called !BMC or bangBMC.

Link: https://gitlab.raptorengineering.com/bangbmc-firmware
Description: https://gitlab.raptorengineering.com/bangbmc-firmware/br-bangbmc/-/blob/raw-first-pass/docs/manual/about.md
Here's the fan daemon: https://gitlab.raptorengineering.com/bangbmc-firmware/op-fan-daemon

It's not mentioned in the wiki AFAICS... It allows to set fan curves at runtime, without requiring recompilation everytime.

I've not used it myself yet and don't know much more than what I've written above.

Sorry FlyingBlackbird for the late reply.

Do you use the NVMe SSD together with any other SATA device (which is my constellation supposed to cause problems - in my case I suspect the optical drive)?

I'm not sure. I have an SATA DVD drive installed now, but haven't used my BB for some time now and don't remember if I used it with the DVD drive, or installed that after stopping using it.

BTW: Did you already try to enable the "cold restart" setting (I don't remember the exact name but it re-initializes the complete hardware when restarting like a real power-on boot phase). There is some documentation in somewhere here and in the wiki

It's called "fast reboot". Personally, I have that enabled because otherwise my GPU (WX3200) sometimes does not reset properly and then disappear from the system (even not in lspci).

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.

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

Firmware / Re: How to setup Secure Boot with PetitBoot

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:

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.
