 Posted: Sun Jul 19, 2015 7:54 pm Post subject: Gentoo on PowerMac G5 |
 |
|
Hi all,
Thsi is my first post and first installation of Gentoo.
I'm trying to install Gentoo on a late 2005 PowerMac G5 with 2x dual core processors.
Unfortunately right after the yaboot screen I get a gray screen with the following:
| Code: |
done
found display : /pci@0,f0000000/NVDA,Parent@0/NVDA,Display-A@0, opening... done
copying OF device tree...
Building dt strings...
Building dt structure...
Device tree strings 0x0000000000d05000 -> 0x0000000000d06764
Device tree struct 0x0000000000d07000 -> 0x0000000000d16000
Calling quiesce...
returning from prom_init
_
|
I can't really tell what the issue is.
I used both the g5_defconfig for compiling the kernel and tried one just by doing manual configuration, both with the same result.
In addition I selected the gnome-systemd profile with eselect profile set.
Any help is appreciated.
Thanks,
Chris[/code] |

Hey so, what's your yaboot.conf? Reason I ask is your ofpath looks kind of funny. Also, what kernel are you using? I'm using 4.1.4(64bit userland) with no problems at all.

Thanks for taking the time to help, installation issue has been "resolved".
I reinstalled the system by:
starting from the partitioning, I left the partitions the same as the previous install and simply rerun mkfs.ext4 on /root
compiled the kernel with g5_defconfig - no options changed, no initramfs installed
selected the desktop profile(no gnome/kde/systemd)
copied yaboot.conf from the previous install, I'm not in front of the ppc now so will need to check if changed anything.
Install went flawlessly, although not sure what I did wrong the first time, but now I'm trying to get graphics working properly, Nvidia NV43 card.
I recompiled the kernel with nouveau support and used VIDEO_CARDS="nouveau" in /etc/portage/make.conf but kernel option video=nouveau leads to a blank screen, sounds like this issue https://forums.gentoo.org/viewtopic-t-1020900.html ?
Furthermore, I installed awesome window manager but the colors are distorted, kernel was booted with video=ofonly and the Xorg log issues errors about kms : [drm] kms not enabled. |

The combination that just gets me to console is: video=nvidiafb:1900x600-32@60 nouveau.modeset=1. Now far as a working Xorg, that is a task that has not been successful for me.

Unfortunately that doesn't work at all for me, some screen output comes up right after yaboot and then a blank screen.
Btw, the kernel I have is 4.0.5.
Would installing an initramfs with nouveau make a difference? |

By the way if you got a properly configured kernel you shouldn't really have to put no yaboot parameters for OFW to use. So, you should try that first and it will by default use offb. At boot prompt boot: Linux nouveau.modeset=0 . For example make sure nvidiafb is compiled as a driver inside kernel. I tried without nvidiafb and wouldn't boot at all with/without any parameters.

That's great info.This is the kernel config I have at the moment:
http://pastebin.com/SQCEnPJ3
Boot parameters:
| Code: | | video=nvidiafb:1280x1024-32@60 nouveau.modeset=1 |
One peculiar thing is that the card only boots when it's connected on the right DVI port as seen from the back otherwise it goes blank.
I can start X with awesome and no distorted colors now.
Got vlc/mplayer running although I had to load the snd_aoa_i2sbus for sound to work.
A[/code]lso both mplayer/vlc complain about low frame which is probably due to X loaded with software rendering:
| Code: | [ 1007.351] (II) AIGLX: Screen 0 is not DRI2 capable
[ 1007.351] (EE) AIGLX: reverting to software rendering
[ 1007.871] (II) AIGLX: Loaded and initialized swrast
[ 1007.871] (II) GLX: Initialized DRISWRAST GL provider for screen 0

Hi Chrishas
Thank you for sharing your experiences in setting up a Power Mac G5 with Gentoo. I'm trying in setting up the same type of equipment and did run into some issues, including the black screen and poor video performance. x86 and x86_64 are by far easier in compare. I will give it another try and use some of your recommendations.

Hi CarstenIQ
I tried troubleshooting/debugging the issue further but I put it on hold until now when I have time again. The following bug report has a patch for the issue in kernels 4.3+ but I haven't tried it:
https://bugs.freedesktop.org/show_bug.cgi?id=91319
Hope that helps,[/url]

Hi Chrishas!
Thank you for sharing this information. I will give it a try and patch the nouveau driver. I was able to get the basic system up and running on the PowerMac G5 but not with full resolution though. If I use the max supported screen resolution of 1440x900 , it is off center. All has moved good 10 to 15cm to the right and trunks the image. I hope that the patch will solve this issue as well.
I still have no Xorg and Desktop Environment working yet. The reason for that is that I wanted Pantheon but it seams impossible to emerge for me since it requires systemd to function and a lot of package conflicts. I prefer OpenRC. So a no go for pantheon there. I hoped to install LXQT as second choice since I use mostly QT based apps or apps that support both, GTK or QT. But I also run into some issues there, too many package conflicts  .
I'm not able to emerge spidermonky-1.8.5-r4, by blocking it I can emerge version 1.8.2.15-r2 without any problems but the dependencies are not anymore satisfied. I will post the emerge error log and emerge info once I have access to the Machine again.
What desktop environment would be recommendable for PPC64 machines? Which supports the best this arch?

I went for KDE, XFCE is also an option. What profile did you select for the installation?
Unfortunately I can't really help much with the resolution issue, what monitor are you using? I've only seen something similar when connecting to a monitor which had smaller maximum resolution. |

Hi Chrishas
today I had access to the Mac G5. The Monitor is a I-INC model iF191D.
My profile:

I did a emerge --sync and an update and so far so good. I will try xfce4 since it is a bit lighter as KDE even it uses GTK.
Here is my emerge --info

Hi Chrishas
I like to express my gratitude for your assistance. I finally got everything working with XFCE4 but the kernel patch did not work for me at all, sadly. It seams to be for kernel version 4.3.
Just to let people know which might also struggle with nouveau and ppc64 arch. I used the vanilla-source version 4.4.0 which seams to have a fully functional nouveau kernel module. Took me a while to figure out  . The stable gentoo-source version 4.1.12 was problematic and had a non-functional kernel module for nouveau. Also I might note, to follow very closely the nouveau Gentoo guide and disable all other frame-buffer device modules. Since I have a Nvidia GeForece FX5200 Ulta in this Power Mac, I uses in yaboot.conf following kernel commands: nouveau.modeset=1 video=offb:off video=nouveaufb:1280x1024-24@60 video=TV-1:d
I hope it will be of use to someone.
