| 08:59.30 | Elowan | hi there, PMFJI - i got jessy installed on a ibook G4 1.07 Ghz and sound is not working. 'aplay' returns, that there is no soundcard found |
| 09:00.58 | Elowan | I un-commented some lines of modules.conf and added "snd_powermac" and got nothing sound-releated blacklisted anymore... |
| 09:04.14 | Elowan | but still no sound. on boot it says: :~$ systemctl status systemd-modules-load.service â systemd-modules-load.service - Load Kernel Modules Loaded: loaded (/lib/systemd/system/systemd-modules-load.service; static) Active: failed (Result: exit-code) since Do 2016-01-07 17:19:17 CET; 13min ago Docs: man:systemd-modules-load.service(8) man:modules-load.d(5) Main PID: 135 (code=exited, status=1/FAILURE) |
| 09:05.49 | Elowan | on shutdown it say something like "can not put back soundcard / alsamixer" |
| 09:05.51 | bikerr | hm, just noticed i dont have sound on my powerbook g4 either, but that might be due to the kernel , just compiled 4.3.3 |
| 09:06.24 | bikerr | [ 14.536208] snd-powermac no longer handles any machines with a layout-id property in the device-tree, use snd-aoa. |

| 09:07.25 | Elowan | ja, I heard, this is a kernel issue with some ic2-thing... I remember yesterday, I did apt-get update and there was a kernel update 3.something, but not 4.x |
| 09:08.01 | bikerr | ok, im on testing on this machine, but im having issues across the board... no gfx accel etc ... |
| 09:08.21 | bikerr | only hope is that the people doing the kernel and mesa for the amiga x1000 etc have a fix |
| 09:08.41 | bikerr | mesa has endian issues, which atleast on my radeon system can take down the whole boat |
| 09:10.42 | Elowan | glxgears works on my end, but for Raedon cards just above mine, it wont - there is an know bug |
| 09:11.14 | Elowan | did you try: |
| 09:11.16 | Elowan | . |
| 09:11.17 | Elowan | Linux radeon.modeset=1 video=offb:off video=1024x768-32 video=radeonfb:off radeon.agpmode=-1 |
| 09:11.19 | Elowan | ? |
| 09:12.30 | Elowan | my raedon 9200 works |
| 09:12.42 | Elowan | without any "fix", right out of the box |
| 09:13.48 | Elowan | 9200 is a rv280 , I guess, but rv300 will not work - so no 3D accel |
| 09:15.13 | Elowan | 9500 and up are rv300 and do not work AFAIK |
| 09:16.14 | bikerr | video=offb:off video=radeonfb:off radeon.agpmode=-1 was working until now |
| 09:16.47 | bikerr | i did manage to apply a patch to mesa 10.6 or so half a year ago that worked somewhat, but would fail and crash the kernel under heavy load |
| 09:17.05 | bikerr | i have rv300 ofc |
| 09:17.21 | bikerr | 9200 i hear is working better yes |
| 09:17.51 | bikerr | squeeze had reasonable performance |
| 09:18.06 | bikerr | bit tweaking ofc , but very decent |
| 09:19.10 | Elowan | so : |
| 09:19.49 | Elowan | image=/boot/vmlinux |
| 09:19.55 | Elowan | label=Linux |
| 09:20.00 | Elowan | read-only |
| 09:20.07 | Elowan | initrd=/boot/initrd.img |
| 09:20.13 | Elowan | append="radeon.agpmode=-1 video=offb:off" |
| 09:20.38 | Elowan | in yaboot and a sudo ybin -v does not work anympore? |
| 09:20.46 | Elowan | ok, good to know ;) |
| 09:20.47 | bikerr | <PROTECTED> |
| 09:20.50 | bikerr | ought work |
| 09:20.58 | bikerr | that forces pci mode |
| 09:21.10 | Elowan | ah, right |
| 09:21.24 | bikerr | but your wise in making a vmlinux.old |
| 09:21.36 | bikerr | going to make a vmlinux test entry too now ... |
| 09:22.09 | Elowan | ok |
| 09:25.45 | Elowan | but anyways - how can I patch the current kernel, to get sound working on ibook G4? do you have any ideas? I´ve found an already patched Kernel on some blog - but you never know, who you can thrust ^^ |
| 09:26.15 | Elowan | so I´d like to patch it myself, but as I am totally new to linux, I got not the slightest idea, how to do this |
| 09:27.57 | bikerr | hehe, well, patches not applied are usually not applied for a reason, and it's a rather laborious effort on our old powerpcs, i compiled 4.3.3 which took like 6 hours, this i5 can do it in .. pff. 20-30 minutes? so the config ought be working out of the box, you dont want to spend 13 hours just because you missed a config entry |
| 09:28.04 | bikerr | but you're on debian stable then i presume ? |
| 09:28.18 | bikerr | lemme do some quick googling , surely there is something |
| 09:28.51 | bikerr | https://ubuntu-mate.community/t/15-10-ppc-on-ibook-g4-bugs-and-general-performance/3231 here maybe ? |
| 09:29.31 | bikerr | the crash described there is quite similar to the one i experience, however thats a Mesa issue, |
| 09:30.42 | bikerr | hehe, ends up with the exact options i've already mentioned .. . |
| 09:30.52 | bikerr | ok, well then sound is a kernel issue.. |
| 09:31.36 | Elowan | yes, on jessy stable |
| 09:31.53 | Elowan | *Jessie |
| 09:32.31 | bikerr | these guys are making gfx work on newer radeons, using a modified mesa |
| 09:32.37 | bikerr | http://amigaworld.net/modules/newbb/viewtopic.php?topic_id=40435&forum=34&40 http://amigaworld.net/modules/newbb/viewtopic.php?topic_id=40682&forum=34&11 |

| 09:33.28 | bikerr | be mike |
| 09:34.00 | Elowan | https://ubuntu-mate.community/t/15-10-ppc-on-ibook-g4-bugs-and-general-performance/3231 was actually written by me, hehehe ;) |
| 09:34.07 | bikerr | if your read that thread, thats pretty much as far as i got, the latest reply tho i will be testing today if i get that far |
| 09:34.17 | bikerr | hah |
| 09:34.44 | bikerr | so were two active i/pbook users then :D |
| 09:35.21 | Elowan | unfortunatly, MATE 15.10 did not work well - I got it running, but CPU was at 30-40% when idle... |
| 09:35.33 | bikerr | seem to be quite knowledgeable for a fresh linux user tho, thats good |
| 09:35.52 | Elowan | on Debian 8.2 install (also with a MATE desktop), CPU was 10-20% IDLE |
| 09:36.26 | bikerr | interesting, but the swrast diver the desktop is not usable really.. . |
| 09:36.44 | bikerr | a slow painful death is preferable to be stuck on that :D |
| 09:36.49 | Elowan | now I did some 'stylish-hipster setup' with i3 windowmanager and a few cool tweaks... |
| 09:37.08 | bikerr | nice, im using xfce everywhere myself, but i |
| 09:37.13 | bikerr | thats down to prefs |
| 09:37.19 | Elowan | and CPU is at 50% speed at 3-10% load on idle |
| 09:37.26 | bikerr | used lxde too for a while .. |
| 09:37.33 | Elowan | ja, this works, too |
| 09:37.49 | Elowan | openstep/box and awesome and such do also very well |
| 09:38.26 | bikerr | i guess this is the only hope now http://amigaworld.net/modules/newbb/viewtopic.php?topic_id=40468&forum=34&start=20&viewmode=flat&order=0#775069 |
| 09:38.31 | Elowan | I got the book maily for learning a bit, 'how to linux' and maybe -if all went well- as fileserver for my owncloud |
| 09:38.39 | Elowan | *mainly |
| 09:38.54 | bikerr | they had similar issues, but they are geard towards newer gpu's |
| 09:39.18 | bikerr | they work good , and i always learn something when i sit down and work with them |
| 09:39.31 | bikerr | did the port of e-uae-ppc-jit to linux |
| 09:39.45 | bikerr | had to figure out cache flush stuff, which meant reading, and im still learning |
| 09:40.17 | bikerr | apparently i have to take into account ppc isa 2.03+ .. .which has different routines for sync after flush |
| 09:47.25 | Elowan | I know e-uae-ppc, think I had it running on MorphOS |
| 09:47.41 | Elowan | and some version on OSX ppc 10.5.8 |
| 09:52.43 | bikerr | nice, i've got mos on the powerbook, not payed for it tho, it ends up being powered off when i dont have time to use it |
| 09:53.37 | bikerr | got it running as low as 10.2 , but at this rate i'll be headed to netbsd on ppc if the condition cant be cured |
| 09:53.55 | bikerr | and i seem only to have time during vacations |
| 09:54.57 | Elowan | japp, time is a precious thing |
| 09:55.13 | bikerr | patch im working on now will cover the x2000 and such, and updating the build script to be compliant with newer automake/conf , so it'll probably be "done" now |
| 09:55.18 | bikerr | the nix part of things |
| 09:55.35 | Elowan | I´d spent a-lot on the ibook |
| 09:55.39 | Elowan | hey, that´s good news |
| 09:56.16 | bikerr | indeed, found a similar cache flush routine in llvm powerpc, had some casting and stuff that i didnt, ended up speeding up a few % |
| 09:57.21 | bikerr | tried my hand on a powerpcspe port too, but not as lucky as with the amcc stuff.. quite difficult when i dont have the hw |
| 09:57.22 | Elowan | ok - if you´re done, please fix the soundcard problem, heheheh ;) |
| 09:57.26 | bikerr | hahah |
| 09:57.31 | bikerr | yeah, then mesa! |
| 09:57.45 | bikerr | is even newer kernel broken? or just 3.x? |
| 09:58.48 | Elowan | from what I´ve read, sound worked in Debian 7 "wheezy" and got broken with Debian 8 "Jessie" |
| 09:59.24 | Elowan | dont know the kernel versions... |
| 09:59.41 | bikerr | if you do a apt-get build-dep kernel-source and get the so called kernel-package ( gotta find the actual name ) you can get away with taking the config-3.x-blaah from boot, stuffing it in a vanilla kernel.org kernel in say /usr/src/linux-4.2 and " fakeroot make-kpkg --append-to-version=-powerbook-kvm --verbose -j3 --initrd kernel_image kernel_headers " |
| 10:00.06 | bikerr | kernel-package - utility for building Linux kernel related Debian packages |
| 10:00.22 | bikerr | but of course, that will take "years" to finish |
| 10:00.56 | bikerr | if you can be bothered with going trough the kernel config and configuring it JUST for your hardware, it can be achieved in a much more timely manner |
| 10:01.32 | bikerr | i ended up having to go trough the config last time tho, and modifying a default config with the network setup of a debian kernel to have network working again... |
| 10:01.49 | bikerr | can find that config, but again, it took hours |
| 10:02.04 | Elowan | ok, but I am not familiar with this stuff! |
| 10:02.11 | Elowan | maybe I shoudl trust http://ppcluddite.blogspot.de/2015/08/debian-kernel-with-sound-fix.html |
| 10:02.23 | Elowan | and just get the already patched Kernel from there |
| 10:02.49 | bikerr | my guess it it's likely fine |
| 10:02.57 | Elowan | guess it, too |
| 10:03.19 | bikerr | any other posts about it on forums etc? |
| 10:03.25 | bikerr | is he distributing the source? '' |
| 10:03.41 | Elowan | but when I really use that old laptop as fileserver for personal data.... I ´d like to be 100% sure ;) |
| 10:04.18 | Elowan | I dont know, he mention 2 patches: https://lists.ozlabs.org/pipermail/linuxppc-dev/2015-May/129212.html and https://lists.debian.org/debian-powerpc/2015/04/msg00086.html |
| 10:05.10 | bikerr | yeah! very much! but the patch doesnt seem to be too complicated . so if you can confirm it's working , the build process for a kernel really isnt that complicated, if you have loads of time, then the method i explain above produces a .deb with kernel image and kernel headers |
| 10:05.24 | Elowan | but it a bit hard for me to wrap my head around it. english is not my main language, as you may guessed already and tweaking config files and installing windowmanager is quiete different from patching the kernel |
| 10:05.58 | bikerr | yep... quite true, and an addictive process :D |
| 10:06.48 | Elowan | time is relative... if it will take 10 hours to compile - no problem, if I am not force to attend this process and I can run it at night |
| 10:07.13 | Elowan | problem is, I put in so much time an efforts, i do not want to kill my sytem |
| 10:07.19 | bikerr | quite true , i made the mistake of leaving my powerbook in the bedroom D: |
| 10:07.26 | Elowan | heheheh |
| 10:07.30 | bikerr | and i run without a battery! |
| 10:08.04 | bikerr | i can write up an something easy enough for you to get stuff compiling |
| 10:08.38 | Elowan | wooot? |
| 10:08.44 | Elowan | sounds good to me :) |
| 10:08.56 | bikerr | should take me like 5 minutes ; ) |
| 10:09.23 | Elowan | take your time ;) |
| 10:10.44 | Elowan | I will not have enough time to try this on my ´book until Monday evening |
| 10:11.22 | Elowan | so... if you manage to write some step-by-step guide till next week, it would be great |
| 10:11.45 | bikerr | http://pastebin.com/THUp1fHS theres the .config i use , will probably need some tweaking for ibook tho, unsure |
| 10:14.15 | Elowan | <PROTECTED> |
| 10:15.37 | Elowan | maybe I should let go, fixing this problem |
| 10:15.55 | Elowan | a fileserver does not need sound anyways ;) |
| 10:16.27 | Elowan | but you know - would be cool, if everything works |
| 10:17.18 | bikerr | Ok, so you see the config for the debian kernels in /boot, think of that as somewhat of a answer sheet for how debian is configured. |
| 10:17.18 | bikerr | first you need the build tools, a simple apt-get build-dep will do, so: |
| 10:17.18 | bikerr | apt-get build-dep linux-image-4.3.0-1-powerpc linux-headers-4.3.0-1-powerpc |
| 10:17.18 | bikerr | then |
| 10:17.18 | bikerr | apt-get install kernel-package |
| 10:17.20 | bikerr | after this. you can either get the sources for a debian kernel, say if you're in /usr/src , as root ofc |
| 10:17.22 | bikerr | apt-get source linux-image-4.3.0-1-powerpc |
| 10:17.24 | bikerr | or go to kernel.org to get a good vanilla kernel, which in many cases can make problems go away! |
| 10:17.26 | bikerr | you then dump the config into the extracted sources, say cp /path/to/somewher/config-4.3.3-powerbook /usr/src/linux-4.3.3/.config |
| 10:17.31 | bikerr | then you go tru the config with |
| 10:17.33 | bikerr | make -j3 menuconfig |
| 10:17.35 | bikerr | after you're satisfied and the kernel should be confiured correctly simply: |
| 10:17.37 | bikerr | fakeroot make-kpkg --append-to-version=-powerbook-kvm --verbose -j3 --initrd kernel_image kernel_headers kernel_source |
| 10:17.40 | bikerr | note, you might even need to be root on debian systems to do fake root, -jn is simply the number of jobs. append to version is simply a name. |
| 10:17.43 | bikerr | you can drop kernel_source if you have space constraits |
| 10:17.45 | bikerr | that should do |
| 10:19.24 | bikerr | ah, you wont need to be root, but since or of building in /usr/src you cant write files to /usr/src , which is where the finished .debs land |
| 10:20.10 | bikerr | after that process simply dpkg -i linux-image-4.3.3-powerbook-kvm_4.3.3-powerbook-kvm-10.00.Custom_powerpc.deb linux-headers-4.3.3-powerbook-kvm_4.3.3-powerbook-kvm-10.00.Custom_powerpc.deb |
| 10:20.18 | Elowan | ok, I will be fine, when loggin in as root, then |
| 10:20.40 | Elowan | but - why shoudl I build a kernel, when there is a new one already made, like linux-image-4.3.0-1-powerpc |
| 10:20.52 | bikerr | just a |
| 10:21.06 | Elowan | I tthought, I just donwload a kernel, but it somewhere and link it in yaboot? |
| 10:21.12 | bikerr | just an example, you need to apply the patch fist , which i dint go trough there, that is simply the process of getting building |
| 10:21.17 | bikerr | applying a patch is easy tho |
| 10:21.23 | Elowan | aaahhhh ok |
| 10:22.18 | bikerr | <PROTECTED> |
| 10:22.18 | Elowan | can I stay with my 3.x kernel and patch this one, instead of going with linux-image-4.3.0-1-powerpc and have the chance of introducing even more bugs? |
| 10:22.52 | bikerr | i'd say thats a good idea , the process i explain simply uses what i had available in my distro to use as an example = ) |
| 10:23.00 | Elowan | is there a way to test a kernel, if there is some malware inside? |
| 10:23.58 | Elowan | or can you tell, in which frequence there will be new kernels for ppc |
| 10:24.02 | bikerr | http://pastebin.com/GDn3NrJW |
| 10:25.13 | Elowan | ok, let´s see if I understood: |
| 10:25.20 | bikerr | well, thats hard, say if you knew what gcc version he had used, then you could figure it out if you built the exact kernel he did, with the exact options ... |
| 10:25.27 | bikerr | with the exact patch .. . |
| 10:26.06 | bikerr | if they are not exactly similar , then toss it out, but of course even a minor difference in system setup and config might cause the resulting binary to differ... |
| 10:26.18 | bikerr | it would be easier to learn the process enough to do it yourself |
| 10:26.24 | Elowan | after DL a patch, I set: patch -p1 -i ~/Downloads/nameofthearchive |
| 10:26.33 | bikerr | its quite well explained so |
| 10:26.58 | bikerr | i'll find a link to the applying-patches.txt in its entirety |
| 10:27.01 | Elowan | then I go: zcat path/to/patch-x.y.z.gz | patch -p1 |
| 10:27.12 | Elowan | and that´s it? |
| 10:27.16 | bikerr | https://www.kernel.org/doc/Documentation/applying-patches.txt |
| 10:28.13 | Elowan | so assign patch -p1 to a patch-file, then zcat it and done? |
| 10:28.33 | bikerr | well , that process for z and stuff is how you would go forth patching a kernel archive with a newer version , minor patches like that one for powerpc isnt too so big it's worth zipping , so patch -p1 /path/to/patch from inside the kernel dir |
| 10:28.48 | bikerr | patch -p1 < ../patch-x.y.z |
| 10:28.58 | bikerr | remember the < ! -..- |
| 10:29.15 | Elowan | hmm, wait |
| 10:29.38 | bikerr | if you've already touched parts of the kernel, then do make mrproper as explained, mind this will nuke the .config , so always keep a backup of that if you've spent hours |
| 10:29.41 | bikerr | yeah, no :> |
| 10:29.44 | bikerr | np* |
| 10:29.45 | bikerr | :D |
| 10:29.52 | bikerr | gonna grab some coffee |
| 10:34.00 | Elowan | so I do not need to install: fakeroot, kernel-package, kernel-source-x.y.z ? |
| 10:35.31 | Elowan | Kernel directory is that : /usr/src/kernel-source-x.y.z on my system ( I am not in front of my ibook right now)? |
| 10:39.01 | Elowan | so I navigate into /usr/src, then do: patch -p1 < ../FILENAME and <enter> ? |
| 10:39.01 | bikerr | to build a kernel the "debian way" you need kernel-package. that contains scripts used to generate the final image, and will install the required tools |
| 10:39.16 | bikerr | fakeroot ought come along with that package |
| 10:39.22 | Elowan | oh dear ^^ |
| 10:39.49 | Elowan | I think it is a tad too much for me, right now |
| 10:39.50 | bikerr | sine you plan on using the debian kernel, i'd say just apt-get install kernel-source-x-y-z |
| 10:40.38 | Elowan | thanks for your help an explainations, bikerr |
| 10:40.51 | bikerr | it's not something done in 2 mins, but once you've learnt the process its quite easy. that said i have small files detailing the process as i can never remember all things from build to build :D |
| 10:40.54 | bikerr | np , np = ) |
| 10:41.13 | bikerr | i learnt this the hard way around kernel 2.4 |
| 10:41.28 | bikerr | easy as crashing a bike these days :D |
| 10:41.28 | Elowan | I can not even tell, what or where I can find that patch on the threads, I linked ^^ |
| 10:41.35 | Elowan | ;) |
| 10:41.44 | bikerr | ah, you can just copy that to a file |
| 10:42.02 | Elowan | ja, but what exactly?! ;) |
| 10:42.09 | bikerr | if you take from under the --- to the --- your fine |
| 10:42.30 | Elowan | first or second link?! |
| 10:42.35 | bikerr | both :D |
| 10:42.47 | Elowan | oh hehehe |
| 10:42.52 | bikerr | from the text i'd say begin with the second one ... . |
| 10:43.02 | bikerr | , this one applied on top of this one, that fix the sound bug. |
| 10:43.09 | Elowan | yes, right |
| 10:43.19 | bikerr | would be wise in naming your files there after :D |
| 10:43.26 | Elowan | sounds, like the first one did not do right |
| 10:43.41 | bikerr | probably for a different device tree |
| 10:45.05 | Elowan | so.... I need to apt-get install kernel-package, then copy the code from the 2nd thread between --- and --- and save to a file |
| 10:45.18 | bikerr | and remember this in /etc/yaboot.conf |
| 10:45.18 | bikerr | image=/boot/vmlinux.old |
| 10:45.18 | bikerr | label=old |
| 10:45.18 | bikerr | read-only |
| 10:45.18 | bikerr | initrd=/boot/initrd.img.old |
| 10:45.19 | bikerr | <PROTECTED> |
| 10:45.29 | Elowan | then navigate to kernel dir |
| 10:45.43 | Elowan | then patch -p1 < ../patch-x.y.z and done?! |
| 10:46.21 | Elowan | so I need to set patched kernel in yaboot? thought, it would automatically do this |
| 10:46.23 | *** join/#debianppc kelsoo_ (~kelsoo@86.53.50.178) |
| 10:46.25 | bikerr | apt-get install kernel-package && apt-get build-dep kernel-image-x.y.z |
| 10:46.35 | bikerr | that will grab the needed files |
| 10:46.51 | Elowan | ok, so I need the exact kernel verison number first |
| 10:47.52 | bikerr | if you do a , apt-cache search linux-image you can see whats available |
| 10:48.32 | bikerr | should not have said this would take 5 minutes to explain as i've now managed to not explain it too well :D |
| 10:48.44 | Elowan | heheeh ;) |
| 10:51.49 | Elowan | got to quit for now - thanks for support and good luck fixing RV300 |
| 10:52.41 | bikerr | thanks np! |
| 10:52.49 | bikerr | good luck to you too |
| 10:53.01 | bikerr | all the docs you need are in the linux-src/Documentation dir |
| 10:53.31 | bikerr | at least i think i've managed to cover the gists of everything |
