User Zone / Re: Gentoo installation issue

« on: October 24, 2024, 11:01:53 pm »

Thank you. I had not figured it out. In the meantime, I had taken the config from the dist kernel, changed it to Power9 and 4K page size and have been running with that. I had not disabled VSX myself. However, looking back, I think my error was that I installed the kernel with the instructions in the PPC handbook, not the PPC64 handbook. That included make-ing the pmac32_defconfig target, which I did think suspicious at the time, but went ahead and did anyway, not realising that I was reading the wrong handbook. I'm going to assume for now that that's how VSX became disabled.

Thank you for your help.

User Zone / Gentoo installation issue

« on: September 08, 2024, 03:15:28 am »

I have an NVIDIA GT710 that I'd like to get working with my Blackbird. After getting past the boot issue by disabling the nouveau module in Petitboot, I still can't get the card to work in the OS. I tried Fedora, Debian and Trisquel. Then, realizing that maybe the 4KB page size issue was affecting me, I decided to try Gentoo. I tried the Distribution (pre-built) kernel, but this also has a 64KB page size, and failed with the same errors as the others. So I compiled a kernel with the options that I thought best, but it won't boot with that kernel. The console output shows:

Code: [Select]

It appears that something is wrong with ld64, but I have no idea what. How should I proceed from here? I wondered about posting in the Gentoo forums, but decided to try here first.

User Zone / Re: Unable to boot with NVIDIA GT710 installed

« on: August 25, 2024, 06:02:42 pm »

Ok, I figured it out... Documenting here in case someone (particularly my self) needs it in the future.
Blacklist kernel module at boot time in nvram by:
1. Exiting to Petitboot shell from Petitiboot menu
2. Executing nvram -p ibm,skiboot --update-config bootargs="modprobe.blacklist=nouveau"
3. Check config by executing nvram -p ibm,skiboot --print-config
3. Reboot
I don't know if this will persist after a firmware update, is there a way to make this permanent?

This resolved the issue with Petitboot, although when the OS boots, it can't initialise the card. The card works fine in my other desktop machine (amd64), but doesn't work in either Trsiquel, Fedora or Debian in my Blackbird system. In all of the distros, Xorg log shows:

Code: [Select]

[   139.646] (EE) [drm] Failed to open DRM device for pci:0000:01:00.0: -19
[   139.647] (EE) open /dev/dri/card0: No such file or directory

Any clue as to what the solution might be for this issue? I don't believe it's firmware, I specifically bought this card because it doesn't require proprietary firmware, there's no mention of missing firmware in the Xorg log, and nonfree firmware is installed in Fedora and Debian.

Thanks for your suggestion. I know how to blacklist a module in an operating system, but not for the boot firmware. Can you provide any reference or tips? I have compiled and installed the OpenPOWER firmware (I was unable to build the OpenBMC firmware), do I need to make some change to the configuration there and rebuild?

Note: the system also boots with an NVIDIA GT1030. I was wondering if the issue was firmware, but the GT1030 requires firmware for the OS to use it, whereas the GT710 does not. Or, at least, it doesn't require proprietary firmware, as it works just fine in Trisquel and Parabola.

I have a Blackbird system in which I'd like to install an NVIDIA GT710. However, after installation, boot gets to the Petitboot menu, but then fails as it searches for boot options. The following is logged in the console:

I've tried with and without the "disable onboard video" jumper installed. The system boots fine with a Radeon HD5450 installed, and the GT710 works fine in another system. What could be causing this problem?
