I don't know if you received my last message, but, if not, feel free to
adopt this package.

Thanks for the pointers. I will try to work on these ASAP (including
some at least another package of mine), since the new version that
they may have package is sure to have many, many fixes and new
features, compared to what we currently have in Debian.

Will do (and migrate everything to salsa and modernize the package,
eliminate patches etc.).

Re: Debian sid testing progress
Hi.
It's been a while (several months) since I last updated my iBook G4 with
Debian, but I recall some stuff not working correctly and I saw those
mentioned in the thread pointed to in a previous email.
On 2018-08-13 14:29, swamprock wrote:
FWIW, I am currently trying to fix the Rust compiler on 32-bit PowerPC so
that we will eventually be able to use Firefox and Thunderbird on PowerPC

That would certainly be very nice, Adrian, since without that, we have
essentially no browser on PowerPC (and, the ones that we had had many
issues that I can't recall right now).
BTW, which browsers are other people working?
Brian, if you can, please tell other people to subscribe to the list or
to use Thunderbird to read the list via news.gmane.org gateway (this
way, people don't get flooded with emails if they don't read their
emails in a timely fashion).
Nice. I wish my coding skills weren't so old-school, or I could offer help
beyond just testing. It would be nice to see Quantum's speed and efficiency (to
the extent that it would be effective) on PPC machines. This could possibly
have a carry-over affect on TenFourFox, the Mac OS X/PowerPC fork of
Firefox-ESR, as Cameron is basically left to applying security patches and
optimizations to the old ESR code.
Some of the code (that is, the non-OSX parts) that Kaiser Cameron is
producing (especially the Altivec optimizations to decoding videos and
the JIT of Firefox) would be quite welcome if supplied in a clean
fashion to Mike Hommey, the Debian maintainer of Firefox (who also
happens to be an upstream developer at Mozilla).
Thanks to all involved with maintaining this port.
You're welcome. Please join us on #debian-ports on OFTC on IRC if you would
like to get into contact. New help is always welcome.
Will do, time permitting. I'll notify the MacRumors thread of your reply.
Thanks!
I saw people mentioning that playing videos with mplayer, vlc etc is
slow on G4 machines. That is because packages in Debian are compiled for
the lowest common denominator, which is no Altivec at all.
Unfortunately, even if I grab the sources of the Debian ffmpeg package
and recompile it with Altivec enabled, but without the -mabi=altivec (or
something like that---don't recall exactly, since, as I said, it's been
months without touching my iBook), there is no change in performance.
Once I add that option (which changes the ABI), ffmpeg can transcode
videos 2x as fast and so on. I expect the same things to happen with
other multimedia libraries/programs (and other programs in general).
Oh, some hints to get VLC, mplayer, mpv etc. working faster on the
PowerPCs is to disable the loopfilter for H.264 videos (the "mp4"
videos) and to enable the "fast" processing of lavf.
Something like the following in your ~/.mplayer/config would help:
lavdopts=fast=1:skiploopfilter=nonref
You can substitute nonref by all (but then, the video gets very blocky).
If you can/wish, you (and other members of the forum) can probably
compile these facts as a FAQ on the Debian wiki (there is an Ubuntu wiki
about PowerPC that is likely to be outdated, but it had some good advice
that may not be appliable anymore, due to software having evolved).
https://wiki.debian.org/PowerPC/FAQ
https://wiki.debian.org/DebianOnPowerPC
https://wiki.debian.org/PowerPC/SoundCards
https://wiki.ubuntu.com/PowerPCFAQ
https://wiki.ubuntu.com/PowerPCKnownIssues
(Maybe unify the contents of the pages above would help and also make
clear what are the issues that are still present or not).
Ideally, some of these issues could be automated and the installs should
"just work".

Specifying the MTD partitions in a device tree
Hi.
I am sending this message to Debian/powerpc, Debian/arm lists because and
linuxppc-dev. While the issue that I'm having is with a powerpc machine,
the arm people may also be of valuable help with device trees, since they
have to deal with them seemingly all the time.
Anyway, the problem that I have is as follows: I have a Kurobox HG (powerpc)
NAS that Riku Voipio donated me a few years ago.
Everything worked fine and I was able to get Debian (since kernel 2.6.20 or
similar) running up to with kernels 2.6.28 (if my memory serves me well).
With kernel 2.6.29, the partitions of the MTD device that this machine has
were not displayed anymore (only one big device was presented to the user).
In a recent exchange [0] with Scott Wood from the linuxppc-dev, I was
finally able to partition the MTD flash device with the original layout of
the device by passing an `mtdparts` option to the kernel.
[0]: http://permalink.gmane.org/gmane.linux.ports.ppc.embedded/80215
It seems, though, that the proper way to fix this issue for good is to
include such description in the DTS files for the particular board (in fact,
at least 2---but potentially 4---boards are affected by this).
I tried a few experiments with writing a patch to the existing dts files,
but I wasn't successful, since I am not sure about a good amount of the
things and I would appreciate some assistance here.
In particular, I don't know if I filled all the fields correctly and, also,
I don't know where I should graft the description of the flash chip in the
rest of the device tree.
Can anybody help here? I am sending a verbosely and dirty patch (not yet
suitable for inclusion in the main kernel tree) that I created (and which
didn't work) with as much information that I know about the system, but I
can surely collect more information.
Ideally, I would like to get many of the things automated and add support
for the Kurobox HD/HG to the Debian installer, so that people with these
devices can breathe new life into their systems (instead of the original
2.4.20 kernel that came with it).
I would ge greateful for anybody that can help here. I hope to both learn
and help with the maintainance of such machines.
Once again, thanks a lot for any help,
Rogério Brito.

This is based on my (successful) experience with partitioning the MTD flash

For the sake of documentation, the option that works is:
mtdparts=physmap-flash.0:3072k@0k(firmimg),448k@3072k(bootcode),64k@3520k(status),512k@3584k(conf),4096k@0k(full)
Unfortunately, my attempts at mimic'ing the line above in
arch/powerpc/boot/dts/kuroboxHG.dts didn't bear fruits so far.

Thanks for the description, but I have some questions.

In which order are they patches to be applied (I haven't looked at them

unsuitable for inclusion upstream (if they are not already)?
3. installed the dependencies and compiled. I followed the instructions on
creating deb packages found on the Debian forums here
http://forums.debian.net/viewtopic.php?f=16t=38976.
Great! Can you put the source Debian packages somewhere (the .dsc and
the .tar.{xz,bz2,gz} ones)? That would be great for continuing from
where you stopped (even better if you put the packaging in a git tree).
Thanks once again,

Hi.
I am trying to use any kind of Java Virtual Machine that is not the Zero VM

Luckily, a reverting all the packages to version 7u65-2.5.2-4 make things
work again.
Is there any information else that I can provide so that we can have this
fixed for jessie?
Thanks,

mesa: Having the same issues as Elimar
Package: mesa
Followup-For: Bug #746272
Hi.
I am having the sasme issues as Elimar is having, under very similar
circumstances (with the exception that my card is a Mobility Radeon 9550,
while his is a 9600).
In particular, I can't run some programs, as they refuse to run. One example
is mpv with the driver opengl. I get, among other things:
,
| libGL error: failed to load driver: r300
| libGL error: failed to load driver: swrast
| [vo/opengl] no GLX support present
| [vo/opengl] OpenGL context creation failed!
| Error opening/initializing the selected video_out (-vo) device.
| Video: no video
| Video: no video
`
And no video appears. I can't also use other programs (desktop environments)
that need any hardware assistance.
If any further information is needed, please let me know. I don't have
access to this notebook as frequently as I'd like, though.
Thanks,
Rogério Brito.

Alternative java/JVM working on armel/powerpc?
Hi there.
I would like to run some programs that require a JVM on alternative
platforms, like armel/powerpc (these are arches for which I have hardware
running Debian, but others might also be of interest). (Please, feel free
to cross-post this message to other ports, if you deem this to be relevant.)
But anything related to Java is too slow on such architectures with the
default, unoptimized Zero JVM and I'm having some problems while trying to
use other JVM implementations that we have in the archive.
Based on this information, is there anybody out there that can help with
investigation of what works and what doesn't? I would love it if people
could perform a simple test by installing the packages scala and clojure1.4?
* Running clojure and typing (+ 1 1) (without the quotes) should give you
back the answer 2.
* Running scala and typing 1 + 1 (again, without quotes) should also give
you back the answer 2.
For each of these cases, does it get faster if you type it again (in which
case the JVM might be caching things)?
After that, can you install alternative JVMs? The packages are:
* jvm-7-avian-jre (for the Avian JVM)
* icedtea-7-jre-jamvm (for JamVM).
To make each be use by default, simply reorder the lines in
/etc/java-7-openjdk/jvm-your-arch-here.cfg
In particular, does running with avian even work? All I got was an illegal
instruction. It is supposed to be a fast and memory efficient JVM and would
be a great thing to get running on arches where you can't upgrade your
memory as easily as with amd64 or i386.
Thanks in advance for any help here,

No 3D on iBook G4
Hi there.
I have an iBook G4 with a RV360/M12 [Mobility Radeon 9550] and I just
(re)installed Debian on it.
I mainly need only to play videos (like lectures from Coursera and
other MOOC initiatives) and, honestly, I don't really care for 3D
graphics, but the video players that I tried seem to do (especially
when they choose an opengl backend).
Anyway, with my current setup, I don't get any kind of OpenGL and I
have provided a snapshot of how things are configured in my system
at:
http://www.ime.usp.br/~rbrito/linux/debug-r300/1385003057-g4-linux-3.12-trunk-powerpc.tar.xz
Please note that I am currently booting with the options
radeon.agpmode=-1 video=offb:off video=radeonfb:off
After struggling a lot, I could get mplayer/mpv/vlc to play some
videos if I force XV to be used as the video backend, but, with mpv, I
get the following message:
[vo/xv] X11 can't keep up! Waiting for XShm completion events...
While this is obviously based on impressions, the whole system feels
like everything is so slow regarding to graphics. :(
Also, not really sure if things are connected to this graphics thing
or not, with Iceweasel 17, I can use things OK, but with Icewease 24,
I simply get a segfault right at the start. Reverting back to version
17 makes it work again. Going back to version 24 makes it segfault
again. And so on. (Yes, everything with both clean and unclean
profiles).
I am now, BTW, using qupzilla for posting this (via gmail). :)
I suspect that newer versions of Iceweasel may be using something
related to WebGL and causing a crash?
If anybody has any hints, please let me know and I will do my best to
provide the necessary information.
Thanks in advance,

Creating a PowerPC task force?
Dear people,
Motivated by:
* the results of the last call to porters
* the fact that PowerPC (at least) used to be an architecture where Debian
shined
* the lack of external support (which means that we should help ourselves)
* the documentation that is too spread
* the need of architecture-specific tools (pbbuttonsd? mouseemu?
gtkpbbutons? anything that needs to be revived? yahoot? grub2?)
I thought: perhaps are people out there that may be interested in shaping up
the powerpc port of Debian?
In fact, since:
* Ubuntu doesn't offer an official PowerPC release anymore.
* Apple has long given up updating the operating system for PowerPC users.
* Major projects like Chromium/v8/nodejs are not available for PowerPC.
* Firefox for PowerPC is essentially dead as far as Mozilla is concerned,
with only a very bright enthusiast working on building it with JavaScript
acceleration (http://tenfourfox.blogspot.com/),
we are essentially orphans of the architecture. Again, would anybody else be
interested in addressing the current problems that PowerPC seems to have?
It would be super nice to work on having the installs as good as possible
(meaning: working with as little fiddling as possible after a fresh
install), integrating intelligence about snd-aoa, snd-powermac etc. in
debian-installer, making the 3D thing work as well as feasible,
automatically suggesting programs (alas, even firmware) that are of use for
a powerpc user?
What about this idea?
Perhaps we can already grab/compile the resources that others have already
kept (say, the Gentoo pages, which are very good, the Ubuntu PowerPC FAQ,
which is another very good resource), an old document that I, a long time
ago, started writing at https://github.com/rbrito/powerpc-tutorial etc.
Of course, having both the document for those people that want to know how
things are done and having the code that just works is the golden goal...
Please, let me know if you are interested in joining efforts. I will only
commit efforts if I see other people contributing, as I have my hands full
already.
Thanks,

Re: No 3D on iBook G4
Dear Michel,

FWIW, it's definitely recommended to use XVideo over OpenGL for video
playback on Apple PPC laptops.
I suspected that since my struggles with xine to get a DVD to be played with
xine, but I needed an expert opinion.
http://www.ime.usp.br/~rbrito/linux/debug-r300/1385003057-g4-linux-3.12-trunk-powerpc.tar.xz
Looks like OpenGL is disabled due to the problem described in:
https://lists.debian.org/debian-powerpc/2013/11/msg00045.html
To be honest, I didn't understand Rubén's intented message when he said
¡Oh, I see!. I guessed (incorrectly?) that he had solved the problem, but
there were no further details...
https://bugs.freedesktop.org/show_bug.cgi?id=71789
Someone will need to investigate this upstream in Mesa.
Ah, OK, so I will try with a bitdepth of 16 as a workaround. For videos,
that should definitely be enough (especially for low bitrate videos).
But, well, I lied that I don't care about 3D at all: I would like to
participate in this course here:
https://www.edx.org/course/uc-berkeley/cs-184-1x/foundations-computer-graphics/1003
which says somewhere that the students will need an OpenGL 2.1 environment,
at least. But that can wait. The current studies are more important than
that one at this moment.
Still, I would love to help so that I can get that working in time for the
next offering (if I can be of any assistance).
After struggling a lot, I could get mplayer/mpv/vlc to play some
videos if I force XV to be used as the video backend, but, with mpv, I
get the following message:
[vo/xv] X11 can't keep up! Waiting for XShm completion events...
This looks like it just can't keep with decoding / displaying the video
in realtime.
I didn't notice if frames were being dropped, but I will pay more attention
and report back what I find after I finish this e-mail and experiment with
the 16 bits per pixel.
While this is obviously based on impressions, the whole system feels
like everything is so slow regarding to graphics. :(
One likely reason for the slowness is that you're disabling AGP with
radeon.agpmode=-1. If your iBook isn't stable with the default AGP mode,
try radeon.agpmode=1 or the other values.
I will try it as well.
I now remember that I reported a bug on kernel.org's bugzilla (to which you
replied) which was related to this notebook locking hard whenever I played a
video (it didn't matter the codec of the video).
Also, not really sure if things are connected to this graphics thing
or not, with Iceweasel 17, I can use things OK, but with Icewease 24,
I simply get a segfault right at the start. Reverting back to version
17 makes it work again. Going back to version 24 makes it segfault

Not necessarily WebGL, but it might be related to OpenGL, yes.
Thanks for confirming that my impressions are, at least, not totally crazy.
IIRC, iceweasel 24 was also when Mike Hommey enabled gstreamer playing in
Debian. Not sure what gstreamer may be choosing as a backend to play HTML5
videos.
One would need to look at a backtrace of a crash to tell though.
The only thing that I tried at that point was a simple strace, but I guess
that running iceweasel under valgrind/gdb would be the better thing to do.
Thanks for your always so nice replies,
Rogério.

Re: YouTube on iBook with Wheezy...?
Hi there.
On Jan 07 2012, Jeff Gordon wrote:
I've tried the FlashVideoReplacer plugin for Firefox/Iceweasel, but that
doesn't seem to work -- no matter which player I've set it for, nothing

Weird.
I see the file being transferred and cached, but pressing Play only
results in the message Stopped in less than a second.
I'm talking with the upstream maintainer of that plugin and I have some
patches that are waiting for him to merge. You can see part of my work at my
github tree:
https://github.com/rbrito/flvideoreplacer/branches
Please, do keep in mind that I am a *real* beginner in Javascript.
If you don't mind grabbing videos on the command line, then you can use
youtube-dl, which I maintain here in Debian and to which I also contribute:
https://github.com/rbrito/youtube-dl
I am more proficient with Python than with Javascript, as you can see.
Also, if you feel alone when you want to browse, say, iTunes U, then you can
try to use tunesviewer, which I am starting to contribute to:
https://github.com/rbrito/tunesviewer/branches
Well, perhaps you see some commonalities in the projects that I maintain
(most of them related to videos), but that's because I like visual stimuli.
:-)
It begins to look like HTML5 may, eventually, be the answer...? But it
seems to require something called WebM...?
Which version of Iceweasel are you using? If you are using what is in Debian
testing or in the backports right now, then you have everything needed.
Then, just visit:
http://www.youtube.com/html5
click the link at the bottom that says Join the HTML5 trial and youtube
will send you a cookie that indicates that you prefer WebM videos.
Then, when surfing many (most?) videos on Youtube, you will see them played
right in Firefox.
Only, when I follow the link at YouTube for that and land at the mozilla
site, the site will only tell me I need a newer version of Firefox and
won't I please download it now.
Those browsers distributed by mozilla won't work on PPC machines, as they
are compiled for x86 machines.
If I go ahead and download it, will I have something that will run in
Wheezy on PPC?
No.
Aternatively, is there any other way to acquire WebM? And will _it_ be
useful on PPC?
See above. Lots of ways of watching videos on non-{x86,x86_64} platforms.
Hope this helps,

Re: Experiences on using zram with ARM?
Hi.
2011/7/14 Rogério Brito rbr...@ime.usp.br:
As many ARM systems (and other embedded architectures) happen to be
memory-starved, I thought about playing with zram (the new name of
zramswap) on some of my systems, but I found out that not all platforms
have zram enabled in the stock kernels in Debian.
So, my question is: does anybody have experiences running zram with
non-{i386,amd64} platforms? It would be nice to know before I start
compiling many kernels and stuff.
I sent this message about 5 days ago and I didn't have any responses
in debian-arm. For that reason, I am resending it to debian-arm and
also crossposting it to debian-{powerpc,user}. Any experiences shared
here regarding the use of compressed ram would be more than welcome.
Just for the record, if the module is available, it should be simply a
matter of issuing:
modprobe zram # load the module
echo 67108864 /sys/block/zram0/disksize # size of RAM to reserve to
be compressed
mkswap /dev/zram0 # create a swap in that area
swapon /dev/zram0 # use the swap on the compressed RAM
The basic idea here is that by compressing a portion of RAM:
* we may be able to hold more content in RAM.
* while we use some CPU cycles, it should beat the option of going to disk.
So, again, if anybody has any feedback on using this on a non-x86
arch, it would be very much appreciated.
Thanks,

Have you tried booting from an OSX disc and running Disk Utility
to repair that device? The OSX installer has a menu option to run
it in case you need to partition your drive.
If he has not yet tried, he could try to use hfsprogs from Debian, which is

Re: Squeeze on Lombard
Hi, Michel.
2011/5/6 Michel Dänzer daen...@debian.org:
Hmm weird, probably an X driver bug. Does the option have any effect on
the distortion of 3D apps though?
I reenabled ColorTiling and the weird problems that affected Emacs
(and other applications) are gone. Should this be filed in any BTS?
Which one?
Unfortunately, this only shows where the GPU lockup is noticed, not what
caused it.
Do the lockups occur with radeon.agpmode=-1 (may also require radeon.no_wb=1)
as well?
No, with radeon.agpmode=-1, I am able to use the computer OK, with no
signs of GPU lockup like before, but the graphics of any 3D
application are still messed like the ones in those photos that I took
before.
I have not yet tried radeon.no_wb=1 till now. Should I use it?
Thanks,

Yeah, as Gerhard pointed out, radeonfb needs to be disabled explicitly. That's nice (thanks again Gerhard), because, then, I was able to use Debian's kernel, which has network and sound working. For some reason, with my own kernel I don't have any of these working, despite the configuration not having anything remarkable of difference. * When I use any 3D application, I get distorted output, as you can see in the pictures in the URL above. Does Option ColorTiling off in xorg.conf work around this? (Verify in Xorg.0.log that the option is taking effect) With that option (and it taking effect), the colors of regular applications (like Emacs) are distorted (like an endian error). If not, does this happen with e.g. glxgears as well? glxgears also have the same kind of striped output and, then, it locks up, as before. :-( But the machine is still working and I can access it via the network, which is the important bit.

Would it be a good idea to file this in some kind of BTS/bugzilla, now
that, at least, I could identify the problem more precisely?

Re: Squeeze on Lombard
Hi once again, Michel.
Sorry for not being as speedy, but I had to go to the doctor yesterday
after those tests.
2011/5/3 Michel Dänzer daen...@debian.org:
Probably the radeon driver is loaded from the initrd (or even built into
the kernel), but the firmware is not available in the same place.
Well, now I could make KMS work:
http://www.ime.usp.br/~rbrito/linux/debug-r300/2.6.39-rc6/
I had to compile my own kernel, because just passing video=radeon to a
regular Debian kernel doesn't supersede radeonfb, even if I make sure
that radeon is in the initrd.
That's because the DRI is completely disabled.
Now, that's not a problem anymore. But there are other problems, though:
* When I use any 3D application, I get distorted output, as you can
see in the pictures in the URL above.
* When I boot with KMS, after, say, 1 minute or so (can't be precise
here) almost all feedback from the window manager stops and I can only
move the mouse cursor. Nothing else is updated. After some 30 seconds
more, the monitor becomes completely dark (but the backlight is still
on).
Have you seen that before?
Thanks,

Oh, you're right. I have put some logs of pure radeon there (see
under the 2.6.39-rc5+ directory there), but I still only got a
software rendering fallback. Just for your information, my main intent
with this machine is to run XBMC, which requires OpenGL 2.0, but, when
falling back to software rendering everything is sooo slow.
There's one catch, though: I had to boot with radeon.modeset=0, since,
if I didn't, I just got a corrupted console, with unreadable
characters and, perhaps, with the boot stuck with init entering
runlevel 2 (just guessing here). Nothing else worked. I can (of
course) provide further information on what I am doing, if told just
what I should do. :-)
Everything here is sid/experimental and I can experiment stuff here,
as it is not in production.

Hi, Michel.
First of all, thank you very much for your speedy and precise answers. It is
appreciated a lot.

Try adding radeon.agpmode=1 to the kernel command line and, if that
alone doesn't help, radeon.no_wb=1 as well.
After waiting about 2 minutes with KMS enabled and radeon.agpmode=1 (I was
actually taking a picture to show you), the system went on and loaded my
desktop. It was full of some weird colors, typical of endianness problems.
I put the pictures that I got, together with some interesting debugging
stuff in the directory:
http://www.ime.usp.br/~rbrito/linux/debug-r300/2.6.39-rc5+.kms/
In particular, notice that radeon DRM is complaining that it couldn't load
the firmware file, but it is there, readable for all:
http://www.ime.usp.br/~rbrito/linux/debug-r300/2.6.39-rc5+.kms/firmware-issue.txt
Also, notice that the glxinfo output, even with the LIBGL_DEBUG=verbose
environment variable set doesn't say anything else to the luser (me) why it
has fallen back to the software rasterizer.
So, if you could provide any assistance here, that would be great.

Just for the record, I have converted both my iBook G3 600MHz and my iBook G4
1.3GHz to grub2 and both are working very well (well, my iBook G3 seems to be
overheating once again, but when it works it is enough to test some programs).
I would recommend it for others to try it and go back only if you have annoying
problems. You problably won't, but who knows? :-)
My main concern with yaboot has been (until now) its inability to specify
initrd, unless given in cfg file. Typically with external disks, when root
device has changed, and the boot stops.
Is it possible with grub2 to specify initrd manually?
As Michel already told you, this problem doesn't occur with grub2: it detects
the kernels that you have already installed (with no need to mess with update
yaboot.conf and run ybin), you can use tab-completion (very handy when you are
in some difficult situation) and all your filesystems can be ext2/3/4, xfs,
btrfs etc.
I just converted things here (in both notebooks) to ext4, as I want to take
advantage of delayed allocation and extents, so I don't know how it would work
with something outside of the ext-family.
I highly recommend it for other people.
And, of course, once you are satisfied with it, you can simply set it as default
in the NVRAM (say, with the boot-device variable of OF).
Hope this helps, Rogério Brito.

Oh, one correction: the R400 above was a typo. It should have been R300.
What's the problem(s) you're having?
Everything is falling back to software rendering and using the CPU to the

Do you want me to show you the output of glxinfo with debug information?
That, and the corresponding Xorg.0.log and dmesg output (at least the
agp/drm/radeon related messages) should be a start.
OK. I just put a before-and-after comparison on my homepage at:
http://www.ime.usp.br/~rbrito/linux/debug-r300/
There you have a description of the notebook, and logs from it running both the
2.6.32 and the 2.6.38 debian kernels.
Please, notice that I have reverted X to the state at stable, but everything
that I said there holds true to the software rendering problem with KMS. When I
use UMS, I get *much* faster framerates in an OpenGL benchmark available in the
repositories (package: globs).
If you need anything else, please let me know.

Would you care to share your configuration for 2.6.39-rc*? Up to -rc3, I was
getting some problems (probably, problems with udev, but I don't quite know for
sure).
Starting pbbuttonsd the cpu_usage gets up much and the backlight dimms to
nearly 0. Without pbbuttonsd the backlight can be controlled via `echo
(0-255) /sys/class/backlight/radeon_bl/brightness` but there is no chance to
control keyboard illumination, sound et al.
OK, so we have people using pbbuttonsd and, I would guess, its company utilities
(gtkpbbuttons, powerprefs etc.). I see that these were removed from the archive.
Are there any good alternatives to this combo? In particular, how does pmud work
in comparison to pbbuttonsd? I am considering (well, now, for quite some time)
jumping in and maintaining it, if the alternatives are not as good as it.

Using a second screen with an iBook G4
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA384
Hi there.
Since I have one iBook G4 here, I think that one use for it would be to put it
to work as a home-theater PC. Unfortunately, it seems that we have some
problems:
* When I plug an external (1920x1080) monitor on it, I can only get 1024x768 on
the external monitor, which is, of course, quite bad. More than that, I can only
use the external monitor if I disable the internal monitor, because, otherwise,
I get a message (paraphrased) that tells me that the largest screen that can be
allocated is 1024x1024.
I can provide the full details if desired. I am using gnome 2's monitor/randr
applet to choose which output to use.
This is weird, because I remember using a hack in OpenFirmware that unlocked the
iBook's ability to use two screens as its monitor in the past. It worked fine
with MacOS X 10.5, but I don't have MacOS X installed anymore. [0]
[0]: http://www.rutemoeller.com/mp/ibook/ibook_e.html
Is it possible to get rid of any of those limitations? Any one of the use of the
external monitor in some higher resolution or the use of the external monitor as
an extension of the internal one would be nice additions.
* It seems that the ready made media center programs (XBMC) use a lot of
OpenGL stuff and that is sufficient to bring this notebook to its knees, even
when browsing the menus. Almost unusable. I tried moovida, and it is definitely
faster, but it has some bugs and upstream seems to be dead (well, the released a
closed source version, but that's only for other operating systems).
This is a pity, since Moovida seems like a very good choice for weaker machines,
but I don't know of any effort to continue maintaining the 1.x series. Sad.
Finally, MythTV seems to insist in having a capture card installed in its
backend and, for that reason, I didn't go much further with it.
Any comments regarding this situation would be quite appreciated.
Thanks,
Rogério Brito.

Sure, no problems. In the worst case of lack of memory, I think that I can try
to lower the ColorDepth to, say, 16. It's not like I will be able to notice
anyway.
BTW, the “Open Firmware” limitation is just a hint for the OS, I think;
you can get larger resolution in linux without this hack. It's just a
soft limitation.
Did not know about that. I thought (but have not investigated) that it had some
effect on the device-tree that is exposed under /proc.
Thanks for the comments. I will post back my results.
BTW, just one invitation: what about if we documented some of the
difficulties/solutions in the Debian wiki for PowerPC? That would be a very good
thing with many good side effects, I think:
* Documenting/making a compilation/knowledge base is fun.
* It may help many others and can be used as a reference (and may help even
ourselves when we forget the exact steps that we took a few months ago and need
to repeat some procedure).
* Make it easy to spot points that need to be fixed/automated in a way that the
rest of the distribution works fine with PowerPC out-of-the-box.
* Make it apparent that the PowerPC port is alive and healthy.
The page at http://wiki.debian.org/DebianOnPowerPC is a good starting point.
I have some collected stuff at
https://github.com/rbrito/powerpc-tutorial
which I surely wouldn't mind including in the wiki pages and, the parts that are
suitable, in the Debian installation manual.
Some things that are simple but which need to be written and not just part of
the folklore are, for instance:
* How can I prepare a rescue/live bootable CD for PowerPC? If our solution is
good enough, this can be integrated into live-helper or whatever it is called
nowadays.
* Booting from a Firewire disk is probably well known for Mac users, but the
same is not as well known for a USB stick/drive/whatever, despite this being
simple enough (just a few lines).
If other people would join me in this, I can start working on this, as I want
PowerPC to have a long life (well, at least, as much as I have access to such
hardware, but possibly more).

Thanks for the comments. I will post back my results.
Just for the record, the solution above works almost perfectly. It even showed
the correct frequencies that the monitor is able to handle (something that
wasn't displayed before). Here is what works:
* only the notebook video enabled.
* both the notebook and the external monitor enabled, with the monitor as the
extension of the internal monitor.
* I could not put the display on the external monitor only. When I turned off
the internal monitor, the external one showed a message that it was not running
at an optimum resolution and, besides that message, was completely black.
Anyway, I am much happier now than earlier.

Kernel compilation working?
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA384
Dear people,
I used to be able to always compile my own kernels, for various reasons.
While I was trying to see if the radeon KMS changes with drivers from
sid/experimental were working, I noticed that my the 2.6.39-* kernels that I
compiled did not boot correctly: they booted up to a certain point (with visible
messages appearing OK), until they hang at a certain point and apparently,
didn't invoke init (I can get more precise information than this).
OTOH, the same kernel configuration works perfectly with 2.6.38 (well, with the
questions for new devices all set to no, as I don't have them).
So, before I endure a long session of git bisecting, is there anybody here that
already know of some issue that may be known?
Just for the record, I have been trying to get something working since 39-rc1,
and having these problems.
Thanks for any help,

Can you provide more information on this? Just for the record, I have revived
*both* my iBook G3 600MHz and my iBook G4 1.33GHz so that I can develop with
Debian here and both of them are working fine (today's sid), without any
problems.
In fact, since I keep my important files in a git repository and I clone it
whenever I need to use another computer of my own, I can't tell (apart from the
keyboard and the speed) that I am using old laptop, and not ia32 one.
What is the most important feature in laptops? Standby mode. The
machine wakes up but the desktop doesn't. Kernel or X issue?
Here the issue may be hairy, because many things may be involved. More details?
Then there are smaller things. Like Finnish keyboard mapping is not
working out-of-the-box.
This sucks. But I am sure that you can fiddle (for now) the contents of
/etc/default/keyboard and have them reflected on X.
Hard to see any progress here. Why is this happening for things that
have been working in previous version?
I had a long hiatus working on ppc here with Debian (and I am just returning),
but I would say that the lack of people actively developing and testing makes
things worse. Now that the bootloader problem seems to be partly addressed, I
hope that we can have more people testing the daily installation images.
I hope to get more involved with debian-boot/debian-cd when it comes to PowerPC,
but I don't have many resources (I only have those 2 notebooks and one Kurobox).
I know nothing about PREP/CHRP/other beasts.
And Wheezy... what is it going to bring us? At least it doesn't boot
at all without video=ofonly on any PowerMac i know.
What kernel are you using? I am not having problems here with any kernel
2.6.39-rc. Something must have changed with the .39 release cycle, because the
configuration files that I have don't work anymore. But I see that Debian only
has 2.6.38 kernels precompiled...
Enough complaining. Maybe I just had too high hopes.
Well, perhaps Debian has set some good precedents and you are just used to them.
:-) But the good thing is that we can fix those problems.

Something that we don't want to happen to PowerPC on Debian
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA384
Dear people,
I know that this is probably not as serious for PowerPC as it was for some other
platforms, but it was, in my opinion, very sad to know that Debian has dropped
support for 2 architectures: alpha and hppa.
For some personal reasons, I felt particularly sad about alpha (I planned to buy
one used machine for my own use), but, now, I sincerely hope that people more
knowledgeable about the architecture reintroduce them as official ports of
Debian again.
As I would really hate to see these things happen to PowerPC, would other people
join me in collecting data for a future requalification of PowerPC as a release
architecture in Debian? Previous qualification/certification data are available
in:
http://wiki.debian.org/powerpcEtchReleaseRecertification
http://wiki.debian.org/powerpcLennyReleaseRecertification
I know that this may sound a bit premature at this stage, but it is better if
we, as a whole, report the errors as early as possible (and, for those that can,
provide a few patches), so that ppc is as healthy as feasible and not in any
danger of being dropped out.
For those that didn't know about alpha and hppa being dropped from Debian,
please read this:
http://lists.debian.org/debian-devel-announce/2011/04/msg0.html

some video hardware acceleration. What were the last versions of the kernel + X

I have one iBook G4 here that has some packages from experimental, a 2.6.38

endianness issues or all those things together.
Hints here would be welcome.

A short tutorial on running GRUB2 on a PPC
(Please, keep me CC'ed, as I am not currently subscribed to -powerpc)
Hi there.
As some people may not consider yaboot to be a bootloader for the long term
(well, depending on your views, not even for the short term), I took some
time to distill, experiment, pull my hair, become frustrated, and write a
moderately introductory post on getting GRUB 2 on my iBook G4.
The post is here:
http://rb.doesntexist.org/blog/posts/running_grub2_on_powerpc_macs/
Please let me know if you find this useful.
BTW, I am just playing with getting Freevec on my computer (well, it should
be faster, since Altivec is essentially not used in current Linux
distributions) and I will keep those that want posted (if you want) when I
have something to show.
Well, right now, I have a very crufty solution that works for me, but that I
am ashamed to publish and ruin the rest of reputation that I have. :-)
Finally, a stupid question: is there anybody out there that knows if the
current Iceweasel in experimental (4.0) has any kind of JIT for PowerPC? I
mean, like TenFourFox (http://www.floodgap.com/software/tenfourfox/)?
If not, their patches are available
(http://tenfourfox.googlecode.com/files/TenFourFox-changesets-20110323.zip).
And the developer's blog is very instructive (http://tenfourfox.blogspot.com/).
(Yes, I know that I could just ask Mike Hommey, but let's see if anybody
here has already tried this).
Feedback is welcome.

Re: Which module should one use for sound on pmacs? (was: Re: debian-testing-powerpc-xfce+lxde, 7/26/10)
Hi, Johannes.
First of all, thank you very much for your really appreciated message.
On Jul 29 2010, Johannes Berg wrote:
The old way was to just load snd-powermac on Macs, and then have it do
nothing. That's wasteful in a sense, but it doesn't hurt.
OK. Thanks for clarifying.
There's no auto-loading built into snd-powermac, and the way I see it
there's no chance there ever will be since nobody even cared years ago
when I worked on this stuff.
Nice. BTW, would writing an auto-loading part be hard for a kernel-illiterate?
snd-powermac will not work on machines where snd-aoa works, they're
mutually exclusive but some older machines need snd-powermac, which,
unfortunately, cannot load automatically.
Yes, indeed. The iBook that I have here needs it.
I suppose one way would be to load snd-powermac only when snd-aoa
didn't auto-load?
Right. The way that things are currently is that snd-aoa is force fed
and causes some machines to not have any kind of sound.
Otavio, who should we talk to to get it working this way for the
upcoming release?
Thanks for your input,

Right. I am CC'ing some people that can potentially have answers to this
question. If you have any comments, it would be nice to get this sorted
out for the distributions. :-)
From a very quick look at the source code of snd-aoa, it seems that the
chips supported are onyx, tas and toonie.
How should the distribution side of this be handled (say, with the
automatic loading of the proper module) with machines that use, say,
tumbler?
It is my understanding that snd-powermac works for more users (almost
all?) of stock apple-based powerpcs and Linux.
Last I tried snd-aoa didn't work. (iBook G4 1,2 GHz) I have to use
snd-powermac to get the sound working. I'm curious as well why it is
so.
snd-aoa works great here on a PowerBook5,8 ;-)
OK, fine that it works for you. :-) It would be nice if it worked for
many others, though. :-) What about snd-powermac, OTOH?

There's this very cool program called dvdisaster, which, among other

In the particular case of CDs, it can also give you a very nice idea of
if the medium is going to die or not, showing you how many C2-errors it

Re: patches to ybin
Hi there, people.

Unfortunately, there are lots of places that still expect absolute
device names. Ybin is one of them.
I've got a patch that fixes this (at least it fixes it in my test
environment -- G4 PowerMac running Debian Squeeze).
That's good. Two questions, though:
1 - have you been able to make a bootable CD or DVD with your patched
yaboot/ybin?
2 - did you have any chance of trying GRUB2?
the details are in Debian bug report #580455
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=580455
Is there some way to get this patch (or something even better)
accepted? What can I do to help?
I just started a revamp of the packaging of yaboot at:
http://git.debian.org/?p=users/rbrito-guest/yaboot.git
The best way to get things now would be to push any patches that we may
have upstream (if applicable in general). I have separated the whole,
monolithic patch in the original debian packaging in smaller patches,
but other things may be desired.
As I am without access to a powerpc box right now, I would appreciate it
if anybody could build the package to see how is its status right now.
If you want it, I can include your patch in my tree.
To the debian-boot people: since I have not heard from anybody, I just
decided to take action and change the packaging. I hope that you don't
mind me preparing an non-maintainer-upload.
BTW, I plan on importing the newer upstream versions into the repository
that I listed above.
That's it for the moment.

Re: please take a look at Debian Bug#589701: installation-reports: Install yaboot on a hard disk - Failed to install boot loader

This is bad. I will try to see what I can do to test the installation on
a new ppc (the bad thing is that, as I told before, my newworld
ppc---an iBook G3---is moribund).
I have provided a partial fix in Debian bug#580455 but I have not
gotten any feedback from the developers.
I look into that with a little more care after I get some sleep. Perhaps
a non-maintainer upload of yaboot is in order.

BTW, I will be in NYC for this year's DebConf (well, assuming that the
plane doesn't crash/fall/etc :-)) and I hope to work on some of the
issues that are annoying us. If you can attend, that would be superb
(and, of course, getting to know more people would be really nice).

Are powerpc packages being sent to incoming from buildds at all?
Hi there.
Something that is making me a little worried: are the powerpc packages
getting from the buildds to incoming?
A quick perusal would make me believe that the answer would be no, since
I only saw 3 packages in incoming.d.o and two of them (irssi plugins)
were uploaded by Rhonda (which I believe still uses her trusty
PowerBook, right Rhonda?) and another one was an non maintainer upload
for quick-installer.
Is there any problem that was not communicated?

Question about a package in experimental built but not present in the archive
Hi there, people.
Please excuse my lack of knowledge about the buildd network, but I would
like to use a package (forked-daapd) that is only present in the
experimental section of the archive, but not present in binary form.
In particular, I just saw that
https://buildd.debian.org/build.php?arch=powerpcpkg=forked-daapd
was attempted and concluded nicely, but that the package has not been
integrated in the archive for the past 7 days
http://qa.debian.org/madison.php?package=forked-daapd
Is there any package of this available? I would like to run forked-daapd
in a system that is way too slow to cope with all the build
infrastructure (which includes a java VM).
Thanks in advance for any help,

That is great. One question, though, if you have the opportunity to
reinstall stuff: do you need a working system for production right now
or can you spare some time to help with potential issues?
In the first case, the way to go would be to just install the current
stable installation and update to a newer version with the packages that
you want.
In the second case (which would have bigger, better long term effects,
even for you, if you happen to need to reinstall in the future), it
would be nice if you could test the newest install CD that you can find,
take notes of the errors that you see and report them to the
debian-{boot,installer,powerpc} mailing lists.
Any ideas??
Hope that helps,

Re: Debian PowerPc installer initramfs-tools generates malformed yaboot.conf created when alternate partitions use UUID= in fstab
Hi there, Rick.

to them).
On Jul 14 2010, Rick Thomas wrote:
I'm willing to give it a try on some of my test machines.
How do I go about installing/testing Grub2 ?
I wrote a summary of what I did some time ago:
http://lists.debian.org/debian-powerpc/2010/06/msg00028.html
One particular point that may not be that obvious is that your current
HFS partition may not be big enough to hold an initial grub2 image with
all the modules (those found in /usr/lib/grub/powerpc-ieee1275/).
Some of the modules may not be necessary, if you are only using
something like ext{2,3,4} on your system: them, XFS, JFS, and Co. can be
avoided to be included in that binary.
Another thing that is worth noting is that the command to create that
initial image seems to have been changed, and it should be grub-mkimage
with a parameter --format=powerpc-ieee1275, instead of grub-mkelfimage.
(Fear not: the comments above may not make sense if you have not yet
tried to play with grub2, but they will after you read my e-mail listed
above).
Another slight problem that may make the automatic installation not so
obvious is that the grub.cfg file will probably list the partition that
you will be booting from as (hd0,foo), where it currently needs to be
(hd,foo), without the zero after hd.
I don't know if the hd0 string that the grub configuration puts in the
grub.cfg is used with/taken from OpenFirmware (in case it would be the
hd alias that OpenFirmware uses for the disk), but flexibilizing this
for systems that may have more than one HD would be desireable (i.e.,
stay with the numbering with the HDs).
But that doesn't prevent one from using grub2 right now.
Hope that this helps,

http://lwn.net/Articles/395459/
The content is probably for subscribers only (but will be free'ed the

It does mention the situation of the various distributions and the

Apparently, the CD that you have is for a x86 architecture. If that is indeed
the case, then it won't boot from a powerpc.
Depending on how much RAM you have, you might like to use a live CD (like
Ubuntu's) and run gparted from there (without mounting any partition from your
hard drive, of course).
Failing that, is there anything like the Firewire/target mode for powermacs? In
that case, you might want to use that as a way to resize your root partition. Or
you could temporarily move the HD to another machine that can run gparted for
you.

Re: Debian PowerPc installer initramfs-tools generates malformed yaboot.conf created when alternate partitions use UUID= in fstab

That being said, I would like to go on and take some care of powerpc (as I have

version of yaboot, to be a little more in sync with upstream.
Two questions, therefore:
1 - is there any problem with that?
2 - would there be anybody to sponsor a possible upload to unstable?
I am including people from debian-boot and the person that is currently listed
as the maintainer of yaboot as carbon copies.
Also, it would be very nice if we had reports from people that tried to use
GRUB2 on powerpc.

That's one of the problems of using a less popular platform. :-(
I was just writing a small summary of what worked for me with GRUB2 on Debian
and I found out that our yaboot in Debian could be more up to date.
According to the Package Tracking System, the latest upload to the archives was
made in 2006 [1] and the yaboot people has progressed a little bit with the
sources available in a git repository. [2]
[1] http://packages.qa.debian.org/y/yaboot.html

We could, perhaps, offer two boot loaders for NewWorld ppc machines in Debian
and phase out yaboot once we know that GRUB2 works fine. (That still leaves
those users of miboot and quik without good alternatives).
- there are currently no DD that care about powerpc problems (or we
could rather say that no people who care about PPC are DDs)
We don't exactly need to have DD's to take care of the PPC problems.
While that would make things easier, it is not a strict requirement, as
long as one has a powerpc machine.
As Michel has told us, we don't strictly need DD's. I also would think that he
would not be completely opposed to sponsor uploads to some of the PPC-related
packages.
That being said, is there anybody in debian-boot that could say any word on the
status of the ppc bootloaders?
My iBook G3 is currently having some weird issues (shutting itself down
or freezing hard), and I suspect that it is due to heat. I intend to
get grub2 to work, once I get it to boot, though.
Just as the quick reminder, I was partially succesful with this and having a
familiar, flexible GRUB environment booting out of this machine was very nice.
The basic guidelines that I followed were those of Jörg Sommer [3], with a few
modifications:
1 - you have to use grub-mkimage instead of grub-mkelfimage;
2 - you have to pass the kind of image that you want grub-mkimage to generate
with the -O switch;
3 - you still have to strip the 0 from (hd0) in the device map file that grub
creates, so that it can generate correct grub.cfg files for the boot time.
[3] http://lists.debian.org/debian-powerpc/2009/06/msg00064.html
So far, I am booting with grub2 by hand from Open Firmware, but that's just
because I didn't want to save the things to the nvram yet.
Does yaboot FTBFS, apart from a powerpc 64 issue? That patch could be
integrated, though, but I don't have any ppc64 machine to see if it
makes sense.
Just for the record, upstream's yaboot already has this issue fixed [4].

That being said, I don't know if it would be worth investing some time

My iBook G3 is currently having some weird issues (shutting itself down

get grub2 to work, once I get it to boot, though.
The short story is to make sure that:

* the grub binary loads the kernel
The longer story:

I wanted to help for a problem with the buildd but Frans Pop told us
that it needed a DD to be solved, and I also have a patch for
util-linux specific to PPC that is waiting for monthes. But there are
only users and simple developers left on the debian-powerpc ML, so
we're a bit alone and hopeless ...
Which patch do you have? Did you push it to the maintainers of the
util-linux package? Or to upstream? Just curious.
Does yaboot FTBFS, apart from a powerpc 64 issue? That patch could be
integrated, though, but I don't have any ppc64 machine to see if it

A build spin of yaboot would be nice, regardless, even if it is just to
make some janitorial changes to the debian packaging. I can prepare some
of those, if Aurélien doesn't mind.

I think that I could help a little bit. If you have access to a faster

You can get a lot of details regarding kernels in Debian here:

something more recent than that 2.6.26 kernel, then you could try the
kernel in squeeze:

ppc with a newer kernel.
I think I got the older stick 3-4 years ago. I'm sure it was the

which distribution I was using at the time - Slackware? Certainly not

around. Getting that to work was comparatively - well, ridiculously
- easy. Apparently, the zd1211rw stuff needed was included in the
2.6.26-2-powerpc kernel. I just put the firmware in /lib, and that
was it.
Well, that's nice that you now have some working wlan. BTW, how/where
did you get the firmware from?
I don't know how much familiar with the concept of a distribution like
Debian, but we usually advise people to prefer to things that are
already packaged. Is that the case of your firmware?

Re: Making module for WLAN stick on iBook
Hi, Sakari.

The compilation script/makefile that came with your module is looking
for the kernel headers where /lib/modules/version/build is telling.
OK; persistent googling led me to
http://blog.calmblue.net/?p=105
Clearly, what was missing was this:
apt-get install linux-headers-2.6.26-2-powerpc
I thought that you had this one already.
Once this was done, the correct version of the kernel headers appeared in
/usr/src, as did the crucial link in /lib/modules/version:
Right.
So, 'make'ing the module for the WLAN stick starts up. However, it soon
stops:
OK.
(...)
/home/sakari/rtl8192su_linux_2.6.0003.0810.2009/HAL/rtl8192u/r8192U_core.c:11754:
error: implicit declaration of function ‘vfree’
(...)
Let us see. If the suffix 0810.2009 means the date on which this
module was made available, then we have a serious problem, as kernel
2.6.26 was released in July of 2008 [1].
[1] http://kernelnewbies.org/Linux_2_6_26
Since the kernel is now in the staging subtree of the kernel, it means
that this kernel module has been receiving heavy rewrites for quite
some time and function calls, number of parameters are not guaranteed
to be stable.
I wish this was easier.
Perhaps you should try a newer kernel, see things working and then try
to understand what happens with your system?
This is more likely to succeed than if you try first to understand the
infra-structure of the kernel (as you would need to understand a
little bit of the kernel development and the peculiarities of this
module and of the wifi subsystem) and then compile a new kernel.

The announcement that it was removed from unstable.

It actually consists of two parts: one for declaration of taxes and
another one for transmission. The one for transmission (even when run

Re: Making module for WLAN stick on iBook
Hi, Sakari.
On Apr 14 2010, Sakari Aaltonen wrote:
It *was* pretty easy. What was obviously missing was prototypes for
vmalloc() and vfree(). So, I added one line to r8192U_core.c:

.
With this change, 'make' succeeded.
Great. That's the easy part (getting it to compile).
'make install' didn't, but all that seemed to be needed was making
directories /etc/acpi and /etc/acpi/events, which didn't exist
previously.
Have you tried installing pbbuttonsd and gtkpowerprefs? Alternatively,
pommed may be of use here.
But this ACPI stuff is, probably, just a peripheral matter.
Everything looked OK, so I rebooted and mounted the WLAN stick.
Unfortunately, nothing seems to be happening with it. 'lsmod' shows
that module r8192s_usb has, in fact, been loaded (automatically),
and 'dmesg' reports
.
Linux kernel driver for RTL8192 based WLAN cards
.
Great.
However, when I say 'ifconfig wlan0 up', the answer is
wlan0: ERROR while getting interface flags: No such device
That's not so great. Did you use iwconfig before ifconfig, though?
Depending on how your wireless network is set up, you may want to
install wpasupplicant etc.
Also, the two-computer (Network Manager?) icon at the top of the
screen that would normally drop down a setup dialog for a wireless
network stays inactive.
However, this is getting close, isn't it?
Yes, it is, but debugging this will get quite harder now. I still would
suggest you to pursue the road:
,
| git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
| cd linux-2.6
| cp /boot/any-config-that-you-want .config
| make oldconfig
| make deb-pkg
`
And install the deb package that is generated. (You may, perhaps, have
to install fakeroot for the make deb-pkg step, but that's just a minor
package).
And, if you don't delete this tree, you can periodically grab only the
small changes that go into Linus's tree and keep following it, seeing
the everything works as intended and having direct contact with the
developers.

Re: Making module for WLAN stick on iBook
Hi there.
On Apr 12 2010, Sakari wrote:
I installed 5.0.4 on an oldish iBook and was pleasantly surprised by how easy

That's great. I have two iBooks here (one G3 and one G4) both running
Linux smoothly and it is a very nice thing to have them useful, with a
newer operating system.
Can anyone comment on what is needed to build a module? I think kernel
sources are needed (at least),
Yes.
but I cannot find a package for 2.6.26-2-powerpc, which seems to be
the version here. My very first attempt failed because the original
5.0.4 installation did not even include the 'make' program.
Would you be opposed to the idea of using a newer kernel? This driver is
already part of the stock (read: Linus Torvalds's) tree, in the staging
area (that is, drivers that are not yet of high quality, but which are
getting improvements).
Perhaps the newer precompiled kernels of Debian's testing or unstable
already have this module neatly maintained so that you can simply
install them an happily use your wlan stick.
(I have not used Debian before, so I may be ignoring something completely
obvious.)
If you want to compile your own kernels, having only build-essential is
enough (it will pull in various other packages needed for compilation of
kernels).
If you want to fine tune your kernel with specific options, you can also
install libncurses-dev and run a more comfortable make menuconfig,
select the features etc.
And, to generate a proper deb package from upstream's sources, just use
something (on the root of the kernel sources):
make deb-pkg

But... When I say 'apt-get install build-essential', the answer is
that 'build-essential' is already installed and the latest version.
However, here are the contents of /usr/src/linux:
OK. That's an important step.

**
So, there is only the .bz2 package. That is not enough, is it?
Quite probably. Just unpack the .tar.bz2 package somewhere else and you
will have the tree that was used to compile your kernel.
Actually, a hint here: it is *not* necessary to compile your kernel as
root. In fact, it is a good idea to use the root account as little as
possible. The compilation of a kernel (or of a module) is not one that
would require being the root user.
Also, the directory that the earlier 'make' complained about,
/lib/modules/2.6.26-2-powerpc/build, is still missing.
Usually, /lib/modules/version/build is just a link to any place where
the kernel is put. You can see where it is pointing to (or if it is not
present at all) with something like:
ls -l /lib/modules/2.6.26-2-powerpc/build
When you unpack the kernel sources (and you can put it anywhere you
like), just make sure the link cited above points to where you unpacked
your kernel.
I suspect there is some very basic capability that I lack to build
modules. I mean, it's not just the A-Link WLAN module that cannot be
built - I don't think I can build *any* module with the current
setup.
The compilation script/makefile that came with your module is looking
for the kernel headers where /lib/modules/version/build is telling.
Anyway, are you really sure that you wouldn't like to use a newer
kernel? The 2.6.26.x kernels are way, way too old.
Hope this helps,

Re: Problems with Debian PowerPC

Debian on PowerPC seems to be in trouble...
I just purchased me a new (used, in fact) iBook G4 and this is the
first altivec-enabled box that I have. It is also a bit faster than my
other powerpc machines.
(BTW, if you can donate a powerpc machine, I am interested in
that---please, reply privately if you can).
1) The daily d-i CDImage for PowerPC hasn't been updated since Dec 12th.
http://cdimage.debian.org/cdimage/daily-builds/daily/arch-latest/powerpc/iso-cd/
I will see with Otávio what can be done from the d-i side of it (I'm not
really up to d-i things, since I've been working with the main
distribution instead of with installers). But I can try to look at it.
2) Even if it were updated, it still would not be possible to install
Debian Sid on PowerPC due to the lack of a linux-image package more
up-to-date than 2.6.30. This problem has existed for several weeks.
Did not know that, as I am usually running my own kernels. Is there any
breakage in any drivers with a current git tree? I just compiled
yesterday a kernel from Linus' tree for an OldWorld mac and it was
successful (actually, that was a cross-compilation).
3) When I install a graphical desktop environment with Squeeze
using the above d-i images, I get a system that is missing almost
all of gnome due to un-resolvable dependency conflicts.
Can anything be done about to fix this? What can I (as a user, non-
developer, but willing tester) do to help?
Well, there is probably things that can be done. The problem would be to
get a more precise diagnostic. And, yes, a tester is always, always
wanted.
For instance, which part of gnome is not installable? Have you tried
seeing the subpackages which gnome uses (if you're going for the
full-blown metapackage---I always stay away from that for philosophical
reasons, as I want a different gnome from what one gets by default).

This would definitely work. Also, do you need a extremely modular

to compile in ext4 support in the kernel.
Then, you could potentially avoid the extra partition with a trick like
Branden's installation instructions, putting things in the same HFS
partition that yaboot gets installed on.

Bug#557892: RFH: hfsprogs -- mkfs and fsck for HFS and HFS+ file systems
Package: wnpp
Severity: normal
I would kindly request assistance with maintaining the hfsprogs package,
which is a pair of programs for mkfs and fsck for HFS/HFS+ filesystems.
The package is developed by Apple, but only a small fraction of the
package is actually used. The current packages in Debian use source code
from Apple's MacOS X 10.4 version (codenamed Tiger).
The original patches adapting things to Linux that I got were monolithic
and I cleaned them up, broken them up (for ease of future work) and
were ported forward against some 5 or 6 (I forgot how many) upstream
releases, but still in the 10.4.x branch of their filesystem.
Now, things are getting cleaner and I have started porting the patches
against the first MacOS X 10.5 version, and most of the patches are
already appliable against that version (with the exception of one
patch).
The package has no bugs in its current version, has no lintian
warnings/errors (when using a new lintian version) and is packaged with
format 3.0 (quilt).
In other words, it is in a mostly sane situation, but as is a tautology,
things can be improved.
There are some things to do and I would kindly appreciate some help with
the forward porting the patches.
The package long description:
,
| The HFS+ file system used by Apple Computer for their Mac OS is
| supported by the Linux kernel. Apple provides mkfs and fsck for
| HFS+ with the Unix core of their operating system, Darwin.
| .
| This package is a port of Apple's tools for HFS+ filesystems.
| .
| For users, HFS+ seems to be a good compromise to carry files between
| MacOS X and Linux Machines, as HFS+ doesn't suffer the problems of
| FAT32 like:
| .
| * huge space waste (in slack space as devices grow faster);
| * ability to create files that are more than 4GB in size (especially
| good for those working with multimedia and that need to carry large
| ISO files);
| * ability to use case preserving (and even sensitivity!);
| * ability to use uid's and gid's on the filesystem.
| .
| Users in general can enjoy such benefits since it is expected to have
| more HFS+ filesystems in use, as Apple has announced Macintoshes for
| ix86-64, besides the filesystem being already supported by PowerPC
| systems since the beginning.

Scary. I think that I will try to understand the general infra-structure

The only problem that I see is that I don't have any powerful machine

Hi, Vincent.
There must be something wrong somewhere, because the original package
*does* have the file mentioned:
http://packages.debian.org/sid/powerpc/pbbuttonsd/filelist
For this reason, I'm lowering the severity and tagging it moreinfo.
Please, could you give us more details regarding since when you started
seeing this?
Also, did you happen to have any power-related package installed?
Can you reinstall the package? Does this fix the problem? If not, can
you purge pbbuttons and reinstall it? Does this fix the problem? This
would, of course, give some hint that other program may have messed up
with pbbuttonsd's configurations (perhaps even a logging/rotating
system).
I'm CC'ing the -powerpc list so that other people can comment on their

I can set it up but I need the correct initrd.gz to make it work.
Well, you can boot a specific kernel with a specific initrd via yaboot
directly from OF, if you need it.
Branden's instructions to install Debian without (temporary) physical
media uses this method of booting.
Hope this helps, Rogério Brito.

Re: 720p video on G4?
Hi there,
Sorry for jumping in late here.

A simple way to check if the CPU can decode the 720p, even with an
ideal GPU :
Gee, I wish that I had both a fast GPU CPU like you guys have (I only
have a G3 and Rage 128 here).
mplayer -vo null movie720.avi
Indeed. Using
$ mplayer -nosound -vo null -benchmark foo.avi
is also a good idea to see how the machine works (if it is not CPU
bound), especially after doing something like:
$ dd if=foo.avi of=/dev/null
to get the file in the cache. Depending on the format of the video (say,
a H.264 video), it takes quite a good amount of CPU to decode the video.
Converting it to a simpler format (say, MPEG-4 Part 2) might be a good
workaround.
To check the memory bandwidth of your machine, one simple-minded tool
that I used in the past is mbw (try: apt-cache show mbw).
And I can report that I got some low-resolution H.264 videos to be
playable on my 600MHz G3 iBook with mplayer and the options:
-vfm ffmpeg -lavdopts fast
This proved to be useful to play even Steve Job's video from this month.
For a source of some short 720p videos, you can try some available on
youtube or on Apple's quicktime section of the site.

Actually, no. Since I have been building my own kernels, I have no

OTOH, many people on -powerpc has sent messages along the lines I
just installed lenny/etch/squeeze/foo on my {Power,i}{Book,Mac} and I
can't get any sound, is there anybody here that can help me?.
It seems that on some G5 machines, snd-powerpc could cause some lock
ups, but the problem was reported ages ago and it seems to have been
fixed. I'm not sure if Charles Plessy (in CC) still has his dual G5
and can test it, but I seem to recall that he once had the problem
and, months latter, tested it again and didn't find any problems with
snd-powermac.
(Is this correct, Charles? My memory seems to be failing me lately.)
So, for a distribution kernel, I guess that, once nobody complains
about the problems, we can just standardize on snd-powermac (and have
people have a working setup) and document the potential (perhaps
nonexistent?) problem in the release notes for the arch.
I am willing to learn a bit about the kernel, but I don't have
knowledge about hardware.
Opinons?

P.S.: Ben, are there low-hanging fruits in the kernel for PowePC on

Re: PowerPC 8500??
Hi, Frank.
On Sep 08 2009, Frank Rubinsky wrote:
I have an old PowerPC 8500/132 (actually, I think it was upgraded -
150 maybe??). I'd like to install Debian on it (my first experience
with Linux).
Since this will be your first experience with Linux, installing on an
OldWorld PowerPC won't be as easy, but still quite doable and, in fact,
a way to rescue such machines, as Apple doesn't seem to care about
them.
The HCL at http://kmuto.jp/debian/hcl/Apple doesn't list the 8500 -
the oldest machines on it seem to be G3s.
So what's the best version of Debian to install?
Others may suggest you to boot into MacOS (the classic version, not
MacOS X), use BootX and then load Linux.
It seems that a version of MacOS 7.x can be downloaded legally somewhere
from Apple's site (please, if you go that route, it would be a good
thing if you posted the link here to the list).
OTOH, I prefer to use something that doesn't require another OS to run
Linux. In that situation, I would use either a boot floppy made with a
tool called miboot or boot using quik (which is, in some ways, similar
to using LILO).
Unfortunately, the OldWorld machines have some problems with their
bios (actually called Open Firmware) and they don't always show you
what is going on if you activate it (pressing the combination Command +
Option + O + F right after the chime when the machine is turned on).
Unfortunately #2, for legal purposes, it is not allowed to distribute
bootable CDs for OldWorld machines (like yours), which is, essentially,
what makes this a patience exercise. If it were not for that, then
installing Linux on your powermac would be as easy as on PCs.
I don't know if modern versions of Debian support installation on your
machine, but you can surely install anything if you get Debian's woody
version of the boot floppies, install a minimal system from there and
just upgrade things to a newer release (having the world of Free
Software at your fingertips).
What I described in the paragraph above is not for the faint of the
heart, but it used to work (I have to get the dust off my PowerMac
9500/180MP which has a G3 upgrade card).
Any special hints/pointers for a newbie appreciated.
Do yourself a favor and read at least a tiny bit of NetBSDs guide to
Open Firmware and the partitioning guide that Branden Robinson wrote
about installing Debian on his old iBook.
Despite the fact that the iBook has a slightly different procedure to
boot the system, once you are running the system, things are much more
similar.
Thanks for your help.
Hope this helps, Rogério Brito.

Right, but now the snd-powermac driver is what is being used instead of

Perhaps BenH (one of the principal developers of Linux on PowerPC) could
shed some comments here with the final word so that we can settle this
snd-aoa vs. snd-powermac for the time being.
If one of the above works, then it will be one point more for the
installer not to install the snd_aoa* drivers by default.
thanks.
i dont know if i will understand if you tell me
the meaning of the commands we have used...
or at least the aim of them.
Basically, I just told you to load one driver for the sound card that
was more likely to work with your hardware (which is more or less
similar to mine) than the driver that was being loaded by default.
ill try to find out on manuals.
To learn a little bit more about what I told you to perform, you can
read the following manuals:
,
| man modprobe
| man rmmod
| man insmod
| man lsmod
| man 5 modules
| man shutdown

(You should have the man-db and manpages packages).
you want any other report?
No, thanks. That's fine for now (unless you have another problem).

Re: Fan control ?
Hi.
Not having a TiBook with a fan, I can't really help here.
OTOH, I have a small comment.
On Sep 07 2009, Shawn H Corey wrote:

To find out which process is using the most CPU time, run `top`.
(To quit, press 'q'.) Once you get its process id (pid), run `ps

You can find things a little bit more conveniently running a
beautified version of top, which does both things pointed above in a
very user friendly way.
apt-get install htop
You can see threads of processes, set CPU affinity (OK, not that useful
for single processor, single core systems, but quite useful otherwise),
kill processes *way* easier than regular top (without memorizing
pid's),
And the best feature of all: it is *SMALL*. (I hate bloated programs
with a passion).
Also, for the problem at hand, a good thing to do would be to use
powertop. Perhaps some other benchmarking tools would be useful to
isolate the problem.
(I'm not sure if the tibook in question needs the fan thermal monitoring
module for powerbooks).

Using flash/video on non-mainstream arches and youtube-dl (was: Re: view flash website)
Hi.
I'm including -mentors on this reply, since some may be interested in
the newer packages that I offer. Please, keep the CC'ies.
On Sep 03 2009, the grv wrote:
And, for your consideration, every three days i want to visit You
tube, Vimeo website, myspace, and so on web services that use a
flash tecnology. Many people use this services, every day.
Are you using Flash for the video player part? If so, then you might
want to check some alternatives.
(Here begins the part that may be of interest to -mentors)
For instance, youtube-dl (present in the unstable part of our
repository) is a handy tool to download the files and it is frequently
updated.
I have newer version of youtube-dl at http://rb.doesntexist.org/debian/
that may be more interesting for anybody using it (it is signed with my
cryptographic key), and you can get the sources at:
dget http://rb.doesntexist.org/debian/youtube-dl_2009.08.08-1~try01.dsc
I frequently use it with aria2c, so that I can download the videos
faster (and, actually, it is a good thing to follow, say, some courses
from universities).
(Here ends the part of interest to debian-mentors).
If you just trust me (you shouldn't, since you don't know me), you can
get a ready-made package from:
http://rb.doesntexist.org/debian/youtube-dl_2009.08.08-1~try01_all.deb
After you get the videos, you can play them with vlc, mplayer, xine,
totem, whatever.
The package clive is another alternative to grab videos from all over
the place. You may want to check the mozilla/firefox plugin for mplayer
so that you can play your videos in place.
All this is available for powerpc too (I use it, and I'm interested in
the platform, as I have some very old powerpc boxes that are still going
strong).
If you are not using a flash player for videos, then using swfdec or
gnash may be an alternative (I'm not sure, since I don't use those).
The lack of flash for those alternative views is actually a plus, since
my computer doesn't get slower when I visit one site or another that
happens to have 100 ads all flying in just one page of my browser and
taking over my CPU from me.
I prefer to *not* use the flash plugin, even for platforms where Adobe
offers one (like amd64), as a way to keep my computer free of non-free
software.
Anyway, you right. I need to shutdown my debian, when i MUST to visit
flash websites.
I'm not exactly sure what you mean here. Which of the uses above is not
covered by your needs?
If you have anything that is not covered here, then you might want to
talk with the swfdec and with the gnash developers. Free software is
shaped by your views, if you participate.
If you don't, then your problems will probably not be addressed the way
that you prefer and the programs won't work your way.
Thank you.
GRV
I'm not sure about others, but I prefer not to talk to a person whose
name I can't really see. I have already read all the arguments (a name
is just a label etc), but I like to talk to a human.
This isn't mandatory, but just a way to get more feedback (at least from
my side).

If you have xorg, then you probably already have the necessary drivers.
It would be helpful if you sent the output of /var/log/Xorg.0.log to the
list (perhaps put it at http://paste.debian.net/ and send the resulting
URL here).
Anyway, if you are not experienced with the command line, you may want
to use aptitude instead of apt-get. Just install it (if it is not
already) and type:
aptitude
without any parameters.
i have /etc/X11/xorg.conf empty.
someone said to copy it from
http://theapt.org/openbsd/xorg.conf
how is this done without typing everything?
cd /etc/X11 wget URL
But I guess that, given your background, you may not be able to fix your
problems if you start with a given configuration.
Just post the details of your machine (hint: use lshw) and post it here
and other people may be able to send you a file that work for them.
Or just Google a little bit. There were (are?) many people running
Debian on TiBooks.
cp [source] /etc/X11/xorg.conf
what is the source path [source] for a pendrive?
That depends on what you are using. If you already have some programs
installed, the pendrive may be already mounted.
mount and dmesg are your friends.
Perhaps you should try to see if anybody in debian-user can help you
with non-powerpc specific parts (like, say, invoking apt-get correctly
or seeing how to grab something from the web).

Do they have powerpc binaries? If not, then I would not follow that

If your company/client bought powerpc-based computers, then I think that

Oracle).
Talking about RDBMSes already in Debian, they should work on powerpc the
same way that they would run on other platforms (ideally). Actually,
most software *does* happen to run as well on ppc as on, say, amd64.
The exceptions are really the vast minority.

Nice. What were the problems that you were seeing and that it fixed?
Please, provide more information with your e-mails or it will be hard to
help you.
It would be a good thing if you could post your xorg.conf file on the
Debian wiki, so that other people can be referred there (and it is also
a very good source of information in general, BTW).
One of the starting points would be:
http://wiki.debian.org/PowerPC
does normal apt-get install xerver-xorg-video-raedon
(Gee, pay attention with your spelling)
modify anything else than xorg.conf ?
Do you really have a radeon card? I'd think that an old TiBook would
have a Rage Mobility M3 card, but there were so many revisions of the
Tibooks that I may be mistaken. Which one do you have?
You can check what is your card by looking at the output of lscpi
(better yet would be to gather information once and for all with lshw
run as root).
Regarding if installing the radeon driver, if you installed it it would
not touch your configuration. Debian systems don't change the
configuration made by the user (or, if they do, they would be
conspicuous about this).

I have a PowerBook G4 and I running Ubuntu 8.04 LTS. I am not
completely satisfied with it and I am thinking of converting to
Debain.
What exactly are the problems with Ubuntu?
(Well, I have my share of problems, but some of them are actually tied
to Linux, not exactly to a given distribution, even though some of them
*are* distribution problems---I'm filing bugs in Ubuntu regarding the
packages that I maintain to get them sync'ed with Debian).
Just how different is the 'Official CD/DVD images of the stable
release' http://www.debian.org/CD/http-ftp/#stable from Ubuntu?
Mathematically speaking, they are different. :-) You might want to check
the testing release, perhaps, if you need newer packages. Or, if you
want a middle ground between stable and testing, you may want to check
debian-volatile and debian-backports.
Does it use GNOME? How hard is it to set up the internet (if I get
that going, I can strikebug/strike ask you about anything else)?
What is set up the internet? If you need a simple DHCP client, this is
quite easy and I'd think that the default user installation would give
you something like dhcp 3.
Otherwise, the files that Debian uses are the same that Ubuntu uses:
just look at /etc/network/interfaces, for instance.
Regarding, what desktop environment gets installed, the first CD
determines what gets installed. The default is GNOME, but, of course,
you can change that.
As a side note, to get support about things that are not specifically
PowerPC, you might want to check debian-user, instead of debian-powerpc.
This way, you will get a good amount more of people reading your posts
and answering them.
If, OTOH, you need PowerPC-specific things, this is the right mailing
list to check.
But, do you really need a whole DVD (or CD, for that matter) for the
installation?
If you can have an Internet connection on the powerbook, you might want
to grab the netinstall CD images, instead. That way, you only get what
you need and you help save some of the mirrors' bandwidth.
I have my /home mounted on a separate partition. Can I easily
remount it under Debian? (I will make backups before I start).
Yes, don't forget to take backups (well, I wish that mondo already
supported powerpc, since that's what I use everyday---but I may be
implementing that in the not-so-distant future; at least for NewWorld
macs).
Regarding your /home filesystem, it should present you no problems
mounting on Debian. I would expect to be zero problems with that.

I meant SysRq, not Ctrl+Alt+Del or Ctrl+Alt+Backspace or Ctrl+Alt+Fn.
i have tried all combinations of keys you guys have told me,

Did you try to start with just the X server? (See the manpage of X).
Also, the logs of the X server should contain precious information (see
/var/log/Xorg.0.log or files named similarly).
so my feeling still is that all works fine, but i just can not see it.
so i would have to type blind all commands to change settings,
wich looks quite hard to achieve.
Well, blindly typing things is not that hard, if you do it with
attention. Also, if you have another computer, you could try to log
into it to see if there was a kernel panic or something similar.
i think i need to restart form the begining, if theres no better idea
A reinstallation from start is usually not necessary.

Re: Proper partitioning
On Aug 19 2009, Jason Hsu wrote:
What are the appropriate partitions for using Debian on a PowerPC?
What powerpc do you have in mind? The partitioning scheme differs
regarding the bootloader that you are using.
If you are using uBoot, then a simple partition scheme like the old PC
scheme works for me. I'm not sure if there is any PowerPC that uses a
partitioning scheme like EFI (or, even, if it would make sense for the
platform).
If you are using a Mac based on PowerPC, you would employ essentially,
the route of creating:
* a first partition that describes the other partions (Apple calls this
the partition map);
* one (plain) HFS partition where OpenFirmware (the BIOS that Macs
use) can load things from---this partition is usually very small
(usually just 800KB of size).
* the other partitions that you would like to have (swap, root, usr, var
etc).
On NewWorld PPC machines, the yaboot boot code is installed in the small
HFS partition (which OF is able to read from), when ybin is run.
IIRC, just using the standard fdisk for Macs gives you a way to erase
everything and create the first partition automatically (perhaps the i
option or something similar). The rest are just regular partitions.
I would be interested to know how other people are using GRUB2 with
NewWorld machines, as when I tried to install it, it complained
something about not knowing how to handle the graphical framebuffer and
I went back to the tried and trusted yaboot route.

I do this when, say, I get a new kernel version (together with other

Of course, if the goal is privacy, then a long time will be needed with

Yes, there isn't much difference. The only problem I faced were initramfs uImages, which were not recognized by the kernel. initrd uImages however worked fine. Actually, one has just to be careful to feed the right kind of kernel image to the bootloader. Knowing which one is needed is half way to the success. Regarding the initramfs/initrd images, I'm not using them at the moment (yes, I do loose the flexibility of, say, mounting the filesystems via UUID, which is kind of neat if you are experimenting with using an PATA or SATA driver for your drive), but I intend to, as soon as I get my own copy of uBoot compiled and a recipe of how to create them, with all the steps described (I still intend to write a tutorial on that). Yes, I do. I have now 2 powerpc-based kuroboxes here: * a Kurobox HD (a simpler one, which is the one that I'm using); * a Kurobox HG (which has more memory, but I still didn't put it to run). I'm quite excited to have them work out of the box with Debian, with pure Free Software (and no non-free Software). Same here. Debian GNU/Linux everywhere (except for the WRT54GL router with OpenWRT). :-) I also have another PowerPC box here which is an old iBook G3 (but still a NewWorld mac), whose form factor I love and would instantly buy a more powerful machine that has all the balance between battery autonomy and the ability to play videos (these are, BTW, my most demanding applications). Well, in the mean time, I'm sticking to what I have and I'll wait for the industry to catch up with necessities. I may be getting an arm-based kurobox in the near future (and, of course, I will be interested in getting better support for it with Linux). I thought arm/armel already supports U-boot images. Thus I was a little bit disappointed when I couldn't find any reference for arm + u- boot in the kernel-package sources. I will, perhaps, get the arm-based kurobox tomorrow and investigate a little the kernel-package sources (but not much). If I can't figure out a solution soon, I will simply try to adapt the script that I sent you (perhaps, polishing it a bit, for instance, to deal with the reinstallation of a package, to be managed properly by the postinst script, a decent preinst/postrm etc). If you have already made some of these modifications, please let me know and I will integrate them. I had problems with kernel versions 2.6.26 - 2.6.30, because a lot of things were changed in the PPC MMU and DMA code. For the embedded platform that the kuroboxes use, I had some problems with the MTD devices. I still have to check what their status is and, perhaps, send one patch to the lkml (or some call to help :-)). The ones mentioned here: http://bugs.debian.org/497738 Thanks for the link! You're welcome. As far as I understand it kernel-package is designed around the old Linux ppc architecture, where every subarch (CHRP, APUS, PReP) needed their own kernel image. The powerpc architecture should allow to run one kernel image on different platforms (given that they share the same CPU type). Yes, the change in the kernel from ppc - powerpc brought some unification, but I don't know many subarch'es to speak in any authoritative way (well, far, far from it---we have some much better informed members here in the list that are knowledgeable about hardware design/issues). IMHO kernel-package should define subarchs like ppc32, ppc64, 40x, 44x, 85xx, 8xx and e200 for the powerpc architecture (like the Kconfig option for the processor type). Then the BIOS or the bootloader would just select the correct dtb or a specific cuImage file. Theoretically... Yes, that would be a good thing in principle, but the fact that we have many bootloaders just seem to make things a bit harder. For instance, we would have to teach quik, yaboot and grub2 to load appropriate kernels for ppc32 (I am not familiar with other bootloaders for OldWorld machines, like BootX or miboot etc). Also, I don't know what is the bootloader that ppc64 uses (if somebody could teach me here, I would be grateful, but as I don't have any access to this platform at all, it would be for documentation purposes). Regarding the bootloader choosing the correct dtb and kernel image, that would be fine, but wasteful for embedded systems. Perhaps generating many binary packages for different flavours, like the kernel maintainers do would be a good thing. Nice that the script I provided you is of use for you. Please, if you happen to make improvements, just send me a patch. For sure! I'll try to add cuImage support. However my bash shell scripting skills are a little bit rusty
