Re: PowerMac7,3 DualG5 with [AMD/ATI] RV360 [Radeon 9600/X1050 Series] GPU not loading firmware...
Thank you for the clue! My knowledge of the inner workings of debian is nascent but growing.
With that clue, I noticed that after installing the firmware packages a new initrd.img was automatically helpfully generated, and the new image does contain the needed firmware as you point out.
old:
:/boot$ lsinitramfs initrd.img-5.14.0-3-powerpc64 | grep R300*
:/boot$
new:
:/boot$ lsinitramfs initrd.img-5.14.0-4-powerpc64 | grep R300*
usr/lib/firmware/radeon/R300_cp.bin
However, updating the grub.cfg to actually use it is a manual step that I didn’t know about/realize I would need to do, so after doing that:
sudo /usr/sbin/grub-mkconfig -o /boot/grub/grub.cfg
The system now boots from the new, proper, image and all is well, the radeon driver is found and used:
$ sudo dmesg | grep radeon

Thanks!
My apologies that people coming into this mailing list are probably often like me, perhaps not deeply versed in debian/linux as yet, and finding themselves having to do a bit more than is needed compared to just booting Ubuntu onto an Intel system (which I have four of at present, for the past several years, and had to do almost nothing to get them to work).
Your patience is much appreciated!
That is now two PowerPC systems converted to debian, one 32bit, and this one 64bit.
I have several more to go!
Best,
Ken
