Firmware / Re: Firmware 2.10 for Talos-II and Blackbird available
« Last post by r34per on February 28, 2024, 07:09:43 am »
I've been trying to compile the firmware to test it out with my rx5300, but I'm having some trouble building the firmware for my blackbird. Has anyone had success in building the firmware? I tried on debian12 ppc64le on my power8 server, and the build fails with a bunch of errors like this-

Code: [Select]

GPU Compute / Accelerators / Re: Radeon RDNA3 support?
« Last post by MauryG5 on February 27, 2024, 01:01:02 pm »
We need to understand what exactly is needed to make it work properly. In recent times they have made several AMD driver updates, to understand if very recent firmware is needed, which versions of Mesa drivers are necessary. I would like to mount a Radeon Pro 7700 rdna 3 for example...

So this means that in theory it would now be possible to use the graphics card like the Navi10, from the beginning and therefore also to load the petit boot... If I understand correctly...

User Zone / Re: Blackbird User Guide: Wrong TPM connector and 'missing' USB 2.0 port
« Last post by draconx on February 23, 2024, 05:22:55 pm »
Slightly off topic, but one idea I thought of was to make a little USB 2.0 hub expansion board connected to a PCIE bracket for the back of the computer, connected to the lone USB 2.0 port with a USB cable. It wouldn't do anything for USB bandwidth, but would give more USB ports for peripherals and such on the back. There are only 2 ports there now, so having more would bring it more in line with x86 boards.

You can very cheaply buy ready-made one-to-four-port USB2 hubs with normal motherboard headers, then you can just use any off the shelf USB bracket or case with USB ports.  I used this one and cut apart a cable with an angled USB-A connector to connect it to the Blackbird motherboard (I wanted to share photos but apparently uploads are busted on this forum).

Talos II / Re: OpenBMC password
« Last post by draconx on February 23, 2024, 04:15:13 pm »
I tried the instructions at graphcore.ai with no luck. But the instructions on the wiki for Resetting the BMC's Persistant Storage worked for me on two systems. After wiping the persistent storage, I was able to log into the BMC with the default password and get all the firmwares updated.

Wiping the entire persistent storage seems like total overkill if the only problem is that you forgot the BMC root password.

All you need to do is edit the shadow file on the overlay filesystem with a new password.

Follow that wiki page instructions to add overlay-filesystem-in-ram to the boot command line via u-boot.  This enables a root console login with the default root password of 0penBmc.  Once logged in, mount the writable overlay partition somewhere, for example:

Code: [Select]
# mount -t jffs2 /dev/mtdblock5 /mnt
Then the simplest way is probably to just copy /mnt/cow/etc/shadow over /etc/shadow, run passwd, then copy the newly-updated /etc/shadow back to the writable partition, for example:

Code: [Select]
# cp /mnt/cow/etc/shadow /etc/shadow
# passwd
New password:
Retype new password:
Retype new password:
passwd: Password updated successfully
# cp /etc/shadow /mnt/cow/etc/shadow

Or just run an editor on /mnt/cow/etc/shadow and manually change the root password hash to whatever you want.  Then reboot, and voila, shiny new BMC root password.

Is there enough space in bootkernfw for navi10 firmware? Last time I tried on the current FW there wasn't enough room for all of the files.

Yes, the BOOTKERNFW partition size was increased significantly to approximately 5MB.  This is one of the main GPU-related enhancements for the v2.10 PNOR.

What are you referring to?

Good question. My personal life's been hectic lately; maybe I dreamed something.

What are the video hardware compatibility issues this fixes, out of curiosity?
