 Posted: Sat Feb 18, 2023 4:56 am Post subject: Framebuffer goes blank after booting powerpc-minimal |
 |
|
Using `powerpc-minimal-20230215T030201Z` and booting the ISO from USB on a 1.4GHz eMac (PowerMac6,4)
From a video recording of the boot, the framebuffer seems to blank straight after "Wiping /tmp directory ...". Fortunately, I could still set a root password and start sshd to continue investigating.
dmesg: (the machine has a failed internal HDD, presuming this is unrelated, but leaving the log entries in)

I guess I can at least continue to set up Gentoo like this (once my PATA SSD arrives), but does anyone with a similar system have any tips?
aside: Linux PPC looks like a lonely place these days, so say 'hi' anyway :) First time back on Gentoo in a while after running it exclusively from 2003-2011, in addition to x86 and sparcs, I've run it on a G4 mini and 'quicksilver' and was really happy with its performance and reliability on those machines. The heavy eMac feels pretty clumsly these days, and I'm not sure of my long term plans for it, but for now I'm wanting to test a game I made on a big endian system, and no longer have the sparc :(

bent,
Try adding nofb to the command line.
The Fx keys provide a list of options and tell how to apply them.

I also have a PowerMac6,4 but it's on 1.25GHz.
I suspect the issue lies with the radeon drm because my system also got a "unable to locate a BIOS ROM" when I installed OpenBSD on it.
From mailing lists and forums I visited, I noticed the problem was reported and I am under the impression that OpenBSD and freedesktop folks don't seem either to have a clue on this problem either don't seem to have found a solution for it as of yet or (I hope I'm wrong) don't seem to bother with our old video cards...
Back to Gentoo, I could not even get close to what bent displayed since my network card, which works under OpenBSD (recognized as "bge0") does not seem to get recognized by Gentoo installation, because it displayed the following lines about it:
>> Starting network ...
>> Waiting for interface eth0 ............
!! Interface eth0 not found!
** Will not try to start network ...
** Network not started; Not starting sshd ...
If anyone could advise me on this network card issue, I would certainly oblige to ssh to it and see what goes after what seems to be the last line displayed and informing "configuring kernel parameters".
I am not sure if it's worth to note, but anyway, I had set the scan to a good 10-minute delay (scandelay=600).
Cheers, |

It really does help. Thanks!
The network card is actually identified in OpenBSD as "gem0" and not "bge0" - bge0 is from another apple system. I apologize for that confusion.
The driver is "gem", described by OpenBSD man page for "GEM 10/100/1Gb Ethernet device".
I kept the dmesg from a previous FreeBSD installation which described the network card also as "gem0" and the driver "gem" for "GEM/GMAC Ethernet device driver".
Now I have two questions. How to get to configuration scripts the wiki mentions that the Gentoo boot media has so I could run net-setup? And would an ip route identify the network card name in Gentoo?
Thanks again. |

No. I just want to know how to access it from the only Gentoo media that I have, the installation CD, since the wiki you mentioned there are configuration scripts in the Gentoo boot media.

No. I would like to know the name Gentoo gives to the network card so I can set it up - would the ip route command suffice? |

I cannot follow the install wiki since as I mentioned my display goes blank.
I attempted to have dosshd in order to ssh the machine and see what goes on with the display but then the installation system states the network interface was not found.
The wiki explains well how to set up the interface. I have no problem here.
The only media that I have is the Gentoo minimal installation cd.
GRUB offers a command-line environment but that net-setup command is not available from there and I cannot seem to find where else to run it. |

I know FreeBSD minimally recognizes the hardware so that I can have a functional display.
The chroot alternative has instructions that seemed quite easy to follow.
I just need to determine the parameters in FreeBSD mount command that are equivalent to the following parameters in these Gentoo instructions:
| Code: | root #mount --types proc /proc /mnt/gentoo/proc
root #mount --rbind /sys /mnt/gentoo/sys
root #mount --make-rslave /mnt/gentoo/sys
root #mount --rbind /dev /mnt/gentoo/dev
root #mount --make-rslave /mnt/gentoo/dev
root #mount --bind /run /mnt/gentoo/run
root #mount --make-slave /mnt/gentoo/run |
From FreeBSD mount man page, I could determine mount -t is the equivalent of mount --types but I need to determine the FreeBSD equivalent to the other parameters (--rbind, --make-rslave, --bind and --make-slave).
Would you know if there is an online man page for Gentoo or, alternatively, if you have access to Gentoo system, could you please paste the output of man mount here? |
