Void Linux for PowerPC

Hi dreadone,

Great work! Very interesting! Could you please post the output of “vblank_mode=0 glxgears” with your Radeon HD6970?

Thanks,
Christian

Ok....stay at home in corona times...::)

here some results of short tests:
- Blender crash.txt is:

- VPN is working with Netzwerk-Manager-Applet.
- Supertux2, Xonotic working.
- KDE connect working.
- Firewire Soundmodul terratec aureon 7.1 works (VLC for example), but in ALSA/JACK/Ardour5 is crashing: see pic.

- USB Audiomodul Tascam us-428 is not recognised. ALSA contain Tascam 428 firmware and .conf in /usr/share/alsa/firmware. Maybe there is something missing?
- USB emi6/2 audiomodul: firmware is in the lib/firmware folder. May be the firmware loader is not working correct?

- Printer still doesn`t work. Keyboard still faulty here.
- Cannot install arcticfox/spidermail,-and web. Are this apps working in Void?
 
xeno74: may be because of 64bit?

wicknix: also the "arcticfox-27.10.1.linux-powerpc64.tar.bz2" - installer?

Greetings
 
No installer in the tarballs. Just extract anywhere and run it from the extracted directory. Also that build wont work on 64-bit void-ppc. All these browsers would have to be rebuilt on void 64 for void 64 (same for the musl versions as well), which might not be possible as void ships with gcc9 i believe. I've only had success building these with gcc4.8 - gcc6.5 on ppc linux.

Cheers
 
Hmmm. So i was going to install the new 32-bit iso on my powerbook again to play with, but then i noticed it has the same endianness color issues i ran in to with spiderweb/interweb with online videos, but this time for regular downloaded videos. RGB is reversed. :-/
Can anyone else verify this? Or try another player on an installed system?
Cheers

wanna install Linux on my dual 1Ghz QS, how Void linux is working whit Nvidia?
Is also a good option for a media server? I have a GE G4 for playing iTunes and download Torrents. Would be any good Itunes alternative on the packages?

thanks.
 
blender just doesn't work on big endian systems, don't even bother trying right now

x1900 mac cards won't work, they use a reduced video BIOS where a part of it is supplied by the OS later, I don't think anybody figured out how to make it work on linux

as for arcticfox 64bit builds, it won't work because void is using modern ABI (the same one as ppc64le) while debian/old fedora are using legacy ABI (the one designed in early 90s); they are completely different, require a different userland, and you'd need to compile the browser for it (32-bit works because there is only one 32-bit ABI)

since it apparently requires gcc6, and we only ship modern gcc, that'd need to be fixed first

@-MB- not sure if a GRUB issue or a kernel issue, you can try booting the live image via yaboot and see what that does.

@pochopsp nope, no chromium on ppc

@powermi about as well as any other distro, nouveau is likely to be pretty buggy

@wicknix another player is likely to work alright, probably an endianness bug in some gstreamer component, likely a specific codec plugin, since gstreamer otherwise seems fine

@z970mp big endian systems will work with any AMD/ATI card that's older than GCN, i.e. TeraScale architecture and older (i.e. HD6000 and some specific 7000/8000 and older, though most 7000/8000 were GCN)

my testing G5 has an R5 235 (which is basically a rebranded and somewhat overclocked HD 6450), which is about as good as makes sense in that machine - plus it's single-slot so it won't block a second internal PCIe slot, you're likely to fill them anyway, you have 4 and you need... the original GPU, the modern GPU, perhaps a USB3 controller, and maybe a PCIe M.2 SSD, that means none of the other slots can be blocked

nvidia is likely to be a hit and miss, because of nouveau bugs; even AMD is going to be relatively buggy in some places, but at least stuff like video and a lot of games will work fine

on little endian systems, any AMD card, e.g. I'm running an RX 5700 XT right now

Ok, ....as i said once before, i don't need a nvidia card to boot the g5q; booting only with the 6970 card after installation. To install linux,i needed it.

By the way: i installed the new debian 10 sid (19.04.) in my g5/2.3. Without problems i installed it with Grub and Mate.

I was thinking, if it were possible to compile google chrome from source, then it'd be possible to use google stadia on powerpc. Modern gaming on powerpc!

honestly i don't know about how well that'll work out chief
stadia's kind of a failure and these systems are 15 years and older at this point. they are sluggish on pretty much everything but it's still nice to see some light being shed upon them ^^
 
there's no guarantee for the libffi symlink to work, the soversion changed because the ABI changed, and if anything inside ever encounters the changed ABI it'll break in an either subtle or very obvious manner
 
Well it works for now in my testing. Anyway, I noticed gcc-6.5.0 is in the repo. Arctic Fox builds fine with 6.5, so you should be able to build void native packages.

Cheers
 
Ahh bummer. Well, Riccardo is close to implementing the ability to build with gcc7. Hopefully when that hurdle is overcome it'll be possible for 8 or 9 eventually as well.

Cheers

@q66_ Does the AMD FirePro V7900 have any problems with big endian that you know of? No ROM issues like the X1900?
 
Hello,
i upgraded today (G5 ppc64) and got this notice:

"linux5.4-5.4.39_1: configuring ...
Executing post-install kernel hook: 20-dracut ...
/etc/dracut.conf.d/vfio.conf: line 5: vfio_pci: command not found
dpkg-architecture: warning: cannot determine CC system type, falling back to default (native compilation)
Executing post-install kernel hook: 50-grub ...
Generating grub configuration file ..."

Maybe it is harmless , or is it necessary to do something?
 
@q66_, since you have included the 4.4 kernel, have you ever thought about packaging the old xf86-video-ati UMS drivers?

The only way to get hardware acceleration working with a Radeon 7500 is running the 4.4 kernel with Radeon UMS enabled at compile-time and the old radeon driver from the UMS times. Otherwise, the screen freezes and flickers endlessly with the new ones. It's a shame, since these machines would work perfectly without that problem, and without 2D acceleration they are unusable.

I have tried to compile an old version of the driver myself lots of times, but it seems like I'm too dumb for that. I always get some compilation errors.
 
these drivers don't work with modern xorg, so no

@dreadone there is no /etc/dracut.conf.d/vfio.conf in the default system, so i don't know what you have been doing, but your local changes are yours to deal with
