snd-aos not working on a PowerBook6,2 (PowerBook G4 12")
Hi! (Please CC: me as I am not subscribed.) In order to make some final tests for the Lenny debian-installer, I have resurrected my PowerBook G4 12" from its grave (CD, keyboard and hard disks are all more or less broken). The sound is not working out of the box with either kernel 2.6.25 (currently in testing) or kernel 2.6.26 (currently in sid). snd-aoa-i2sbus gets loaded automatically, but does seem to register any sound device. No single messages in the kernel log. I can get some sounds back by doing: # alsa unload ; modprobe snd-powermac Is the issue already known? Could anyone point me to the relevant bug reports in such case? As snd-powermac seems to work fine, I think this should be fixed by either making snd-aos works or by automatically loading snd-powermac. Any help on achieving this would be great! :) Cheers, -- Jérémy Bobbio.''`. [EMAIL PROTECTED]: :Ⓐ : # apt-get install anarchism `. `'` `- signature.asc Description: Digital signature

With Iceweasel it is slow on G5 and fluid on Intel.
With the same graphics card and drivers?
Good point.
A last example to explain the feeling of slowness: aptitude. To avoid
differences in package lists, I ran `aptitude full-update' in an up to
date sid cowbuilder (yes, there can be smarter system for benchmark, but
on the other hands we can expect some kind of standardness). On a dual
2GHz G5, the command takes around 4.1 seconds to complete. On a Core2Duo
2 GHz (amd64), it takes around 1.5 seconds.
If you want to factorize out pure cpu/memory performance versus video
performance, you'd have to make sure the commands you're trying don't
trigger any screen output.
Run something like:
LOGFILE=`tempfile`; time $your_command > "$LOGFILE" 2>&1
(Or, to make sure there's no difference if one of your systems have /tmp
on tmpfs and the other doesn't, run
time $your_command > /dev/null 2>&1
)
With my lack of technical knowledge, I am obviously going nowhere. But I
hope that I can trigger the curiosity of somebody who would eventually
find "someting missing" in the default config of powerpc machines…
Have a nice day,
Some ideas:
- check whether cpu frequency scaling works, i.e. you're not always
running on a lower than maximal cpu frequency. (How?: this works on my
x86_64 machine:
$ grep -i mhz /proc/cpuinfo
Or, better:
$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
(as root):
# cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq
and to set it manually to "performance" mode:
# for f in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do
echo performance > "$f"; done
)
- a simple cpu benchmark I'm often using for quick checks is:
(this is on a Core 2 duo at 2.5 Ghz, with perl 5.10.0-11.1 from lenny)
[EMAIL PROTECTED]:~$ time perl -we 'for(1..1000) { $z++ } print "$z\n"'

Obviously this is also a little dependent on the Perl version but that
factor shouldn't make more than maybe 10% of a difference. And Perl
*might* also be tuned better for x86{,_64} than ppc, of course -- but on
G3 machines this gave very comparable numbers for me (I did not see much
of an advantage for the x86 architecture).
Also make sure your system isn't running any background jobs, of course;
check with top. BTW if you press "1" in top you'll see the load on each
cpu separately.
Christian.

hardware to give away
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
hi debian hackers!
first off, i thank all of you for your efforts, debian and debian-
based distributions wouldn't be as good as they are without a porting
team as agile and eager as you guys are.
i'm writing today because i have hardware to give away. i'm moving out
of a house and into a flat, so there is no space to keep all this
stuff anymore. please feel free to contact me with detailed questions
about the hardware. it is absolutely free, but given away only on 2
conditions:
a) you have to get it yourself. i will neither ship it nor will i
bring it to you by other means. i live in ingolstadt, bavaria, germany.
b) you are not allowed to sell it. this is the same term i agreed to
when i got most of the hardware, it is and stays free!
here's the list:
MIPS:
6x SGI Indigo2 (mixed green and black, no R10k unfortunately, one has
a pc-compatible serial port soldered to it)
1x SGI Challenge S
1x Cobalt CacheRaq 2
1x Cobalt Qube
SPARC:
1x UltraSPARC 30 complete with monitor, keyboard and mouse
1x SparcStation 20 complete with monitor, keyboard and mouse
1x SpacStation 5, keyboard and mouse included.
PowerPC:
1x PowerMac 7600/132
1x PowerMac 7300/166
m86k:
1x Mac Performa 630
1x Mac Quadrata 950
1x Mac IIcx
x86:
1x Compaq(!) ProLiant 3HE 2xPentium2 400 with 128 MB of ECC RAM and
some fat raid controller (this baby really needs a new home...)
these MIPSen have been lended to me, but i have yet to hear from the
owner, so you can queue up for access:
1x SGI Indy (with linux compatible graphics card, iirc. complete with
camera and monitor)
1x SGI IRIS Indigo ("the coffee maker")
i can not guarantee all this stuff is working, but it should. i'm
pretty sure one of the monitors was broken, so that info might be off
a bit. most of the disks have been completely wiped, the machines were
donations by companies using them beforehand, so you know why that's
kinda obvious.
background information: i have been maintainer of the ROCK Linux MIPS
and SPARC ports, and done some work on PowerPC, too. I guess you know
the SGI IRIS Indigo is not supported (R3000), and that the Indigo2
have graphics cards unsupported by linux. I have no clue about m68k.
please respond soon, i will have to get rid of this enormous amount of
matter as of around august 25th.
be safe,
fake
P.S.: sorry for cross-posting on all the lists, i admit i'm lazy
P.P.S.: please CC me in case of on-list discussions/questions, i am
not subscribed to any of your lists. thanks.

New ATI RADEON Mac Edition
Hello people. I installed today a new graphic card for my PowerMac G4. But have problems with GNU/Linux... No detects the correct Video Card. Linux detect this model: ATI Technologies Inc Radeon R100 QD [Radeon 7200] But this model have 64MB of video memory... my video card have only 32 and the kcontrol detects 128mb How i will change the model...

Sorry, this number should have been (I did forget the wait call first
and then added it without also giving the new timing results):
