Wow. So lets see what the time and the next release brings. Maybe we can
use the airport extreme card with this technology.

3rd sensor not shown (adt746x)

[Joerg Sommer]

Hi,

I've installed TemperatureMonitor.dmg.gz on OS X and it showed me three
sonsors. I've took a look on the dmesg output and found this:

adt746x: version 1 (supported)
adt746x: Thermostat bus: 1, address: 0x2e, limit_adjust: 0, fan_speed: -1
sensor 0: PWR/MEMORY BOTTOMSIDE
sensor 1: CPU BOTTOMSIDE
sensor 2: GPU ON DIE

But in /sys/devices/temperatures/ is nothing to see from the first sensor:

$ ls /sys/devices/temperatures/
bus   power  sensor1_location sensor2_location
devspec   sensor1_fan_speed  sensor1_temperature  sensor2_temperature
limit_adjust  sensor1_limit  sensor2_limitspecified_fan_speed

Where is it? And for what is this sensor?

TemperatureMonitor showed me also a sensor in the battery. Is it
accessable from linux? I noticed often while charging the battery gets
very hot.

Bye, Joerg.

Does "GPU ON DIE" control a fan? And why ommit this information, only
why it has no fan? How else can I get this information?

I can't interpret what that means:

Was this so much code, that is would take an extra effort to maintain it?

ioreg for linux

[Joerg Sommer]

Hi,

OS X has a tool /usr/sbin/ioreg. Is there an equivalent in linux? ioreg
shows some more informations about the battery. I would like to get this
informations on linux, too. Exists a document how to sniff a program in
OS X?

Try the old device name: ttyS0

And isn't it possible to use OpenFirmware to switch the console?

I don't know of anyone. Bbut the gcc package /should/ offer the
possibility to build a cross-compiler. But this doesn't work with the
current gcc packages: http://bugs.debian.org/319624 Maybe someone is more

temperature sensor powers off ibook?

[Joerg Sommer]

Hi,

since two weeks my iBook is often powered off after I went to outdoor
with it. This is the first winter since the kernel supports sleep mode
for my iBook G4. I don't have any other explanation for this phenomenon
than there is a temperature sensor in the iBook that shuts it down (while
it sleeps) when the temperature is to low. Is this true?

I have nothing changed in the kernel or the kernel itself before this
problems start and I see it only when I was outdoor. I carry my iBook
only in a second skin and a backpack. Did anyone have the same problems?

Have a nice weekend, Jörg.

Maybe, but I wouldn't expect it. I took my ibook so often under the arm

No. The second skin doesn't leave the space to open the lid.

Yes, now as you say it, I can confirm this for an iBook G4. I had the
same problem with high CPU load. The fan starts spinning and increase
its speed until it runs very fast. Then it starts to pulse (increase
speed -> decrease speed -> inc...) and after a minute or so the iBook
powers off. I thought the firmware caused the shutdown due to a too
high temperature, but if I hear you, it makes me wonder. I think I
could reproduce this, but it happened some times ago. Since then I pay
attention on the CPU load and run programs like firefox with nice to
make cpufreqd do not speed up the CPU.

$ cat /proc/cpuinfo 
processor   : 0
cpu : 7455, altivec supported
clock   : 606MHz
revision: 0.3 (pvr 8001 0303)

detected as : 287 (iBook G4)
pmac flags  : 001b
L2 cache: 256K unified
memory  : 640MB

I've run pbbuttonsd and cpufreqd to scale the CPU.

pbbuttonsd: call pbbcmd in power scripts

[Joerg Sommer]

Hi,

I want to increase or decrease the backlight level upon plug in and
unplug the power supply unit. I achieve this with a script in
/etc/power/event.d/. But it seams the script hangs in the call of pbbcmd.
Is this possible? If I enable the call I get a message "INFO: Script
'/etc/power/pmcs-pbbuttonsd resume ac ram' lauched but killed after 6
seconds". I tracked it down to the call of pbbcmd. So what might happen
there?

Build the bcm43xx with own kernel

[Joerg Sommer]

Hi,

I tried to build the bcm43xx driver from the debian package with a
self-made kernel, but I failed.

Firstly I needed the header files for ieee80211softmac. After building
and installing the package I found the include files in
/usr/src/linux-headers-2.6.15.1. The bcm43xx make file searches for them
in my kernel tree /usr/src/linux-2.6.15.1/. How can I "merge" them except
copy the header files into the kernel directory?

But I did it (copy the header files into the kernel directory) and then
got this message:

I've build from the kernel source tree /usr/src/linux-2.6.15.1/ with
make-kpkg. I did not build a separate kernel headers package. Should I
do?

Kind regards, Jörg.

You should add these lines to debian/rules for the build process

#v+
ifeq "$(wildcard $(KSRC)/include/net/ieee80211softmac.h)" ""
$(MAKE) SOFTMAC_DIR=/usr/src/linux-headers-$(KVERS)/include 
KDIR=$(KSRC) KVER=$(KVERS)
else
$(MAKE) SOFTMAC_DIR=$(KSRC)/include KDIR=$(KSRC) KVER=$(KVERS)
endif   
#v-

BTW: Why did you write the variable _before_ the make command?

But the build raises this messages again:

#v+

No, I thought this was a submenu only, not a config point with real code

Your hint made it working. I've now a new kernel and the bcm43xx module
is loadable.

So, I would suggest the ieee80211softmac source should check for this
option.

bcm43xx with WPA

[Joerg Sommer]

Hi,

I tried to use the bcm43xx driver with wpa, but it does not work. I've
applied the patch from
http://www.mail-archive.com/bcm43xx-dev@lists.berlios.de/msg00480.html
and loaded the new module, but wpa_supplicant reports "operation not

Me too. I fixed it by unpacking the mplayer-skin-blue package,
manipulating the status file, configuring the package installing
mplayer-g4 and reinstalling mplayer-skin-blue.

I build a new package of v0.5.x[1], but it does not work (same message).
How do you bring your interface up? How do you call wpa_supplicant? Run
you other commands?

I did not apply the patch correctly. After doing this, I get
wpa_supplicant working, but not really. The output is at
http://www.minet.uni-jena.de/~joergs/wpa.log and at
http://www.minet.uni-jena.de/~joergs/iwevent.log I put the output of
iwevent while running wpa_supplicant. Can someone tell me what goes wrong?

On IRC, I've got the to build with dscape, but the debian modules do only
provide softmac and the only stuff I found for dscape needs a new kernel
2.6.16-rc1.

I couldn't confirm this. I heard from this problem from people with PC
laptops, but I see the battery load in the task bar of my window manager
and I noticed, it must fall under 95% before a new charge cycle begins.
With PC laptops a new cycle starts by 99% which leads to the effect

At me my ibook wobbles if I remove the battery. You don't have this
problem? What version of ibook you have? G4?

Questions about Open Firmware

[Joerg Sommer]

Hi,

some questions about Open Firmware.

Can Open Firmware read a msdos partition table?

Is it true, that OF can read ext2?
http://www.kernelthread.com/mac/osx/arch_boot.html (Section "Bootloader"
or search for ext2)

If so, why yaboot needs an extra partition?

Bye, Joerg.

d-i: CD/USB image

[Joerg Sommer]

Hi,

monday, I crashed my system and needed a rescure system to repair my
broken install. I've didn't found the file "boot.img.gz" as named in [1].

Because I didn't have mac-fdisk available I wrote the CD from [2] in
/dev/sda. Then I could boot it with 
"boot pci/usb0/[EMAIL PROTECTED]/[EMAIL PROTECTED]:2,\install\yaboot" from the 
Open Firmware
prompt. I've got the yaboot prompt, but there was the end, because the
bootloader thought it was booted from a cd and searches the kernel on the
not existing cd.

Was there a way out? Shouldn't this way named in the d-i manual? It is
really easy and what is more important: you can prepare the image on a
non-ppc system.

Jörg.

Re: Sleep patch and kernel 2.6.10

I've tried to apply the patch by hand, but there where changed from .9 to
.10 which I can't interpret. In radeon_pm.c the radeon_pci_resume()
function changed in a way, that makes applying of the patch impossible. I
think only Ben can do so, because he knows what his patch should do.

PanelOff in X doesn't work

[Joerg Sommer]

Hi,

I compiled xserver-xfree86-dri-trunk with UseFWPLL and no I have a cloned
screen. But PanelOff doesn't work. For the external screen only I use the
following section:

Section "Device"
Identifier  "ATI External"
Driver  "radeon"
BusID   "PCI:0:16:0"
Option  "AGPMode"   "4"
Option  "APGFastWrite"
Option  "PanelOff"
Option  "MergedFB"
Option  "EnablePageFlip"
Option  "MonitorLayout" "CRT"
EndSection

But PanelOff doesn't turn off the panel. A white light cames up from the
bottom and let the screen glow. With pbbutton I can turn off the panel
(make the background light zero)

After X shutdown the panel gets enlighted, but pbbutton doesn't recognize
this, which cause strange effects upon backlight increase/decrease.

Does anyone use PanelOff?

Jörg.

performance of xine

[Joerg Sommer]

Hi,

IIRC the theme is not new, but was there a solution? I've played a dvd
with xine and cpu usage was 100%. With mplayer I get false colors, but it
needs nearly 50%. (this was with XV) With xshm my dvd jumps and it isn't
a usable quality.

BTW: Does xine support OpenGL output?

Right, this helped. Thanks.

And maybe the problem of xine is not in libxine, but more in xine-ui with
uses xv for output. mplayer performes with xv output bad, too. Can xine
use x11 output?

Note: pbbuttons with IPC problems

[Joerg Sommer]

Hi,

I've had a very strange problem. gtkpbbuttons and pbbcmd report

$ LANG=C pbbcmd query SLEEPKEY
ERROR: Problems with IPC, maybe server is not running.
$ LANG=C gtkpbbuttons -a /dev/sound/dsp 
ERROR: Can't create message port for client.

The cause was, there were not enough IPC channels. A simple

echo 32 > /proc/sys/kernel/msgmni

helped. An entry in /etc/sysctl.conf is for permanence.

Hope this information helps someone sometime.

Do you use ntpdate or something? Try it! The hwclock init script should
save and reload the hardware clock on shutdown and boot. Are there any

Bad option.

Is it correct, there is no way to disable sound for a theme with sound?

mouseemu replacement in pbbuttonsd

[Joerg Sommer]

Hi,

my problem with the touchpad is, while typing hitting on the touchpad and
this generates a click and my cursor jumps away. I know mouseemu exists.
But pbbuttonsd already watches for key events. Isn't it possible to make
it switch the mode of the touchpad, while typing?

hdparm on iBook G4

[Joerg Sommer]

Hi,

today I read a cd with only treble speed. I run hdparm and saw it runs on
mdma2. Is this more than udma2? I tried to set the later, but since this
all accesses to the cdrom hang and never returned.

# hdparm /dev/cdrom 

/dev/cdrom:
 IO_support   =  0 (default 16-bit)
 unmaskirq=  1 (on)
 using_dma=  1 (on)

 readahead= 256 (on)
 HDIO_GETGEO failed: Invalid argument
# hdparm -i /dev/cdrom 

/dev/cdrom:

 * signifies the current active mode

Have anyone different configuration? How fast can you read cds?

The manpage of hdparm says about the switch -X: you'll need to prepare
the chipset for UltraDMA before setting dma mode. How to prepare the
chipset? Is this necessary?

Wheter or not I run hdparm -X udma2 /dev/cdrom, I see the above
configuration.

While we talk about hdparm: How to disable the write cache of the disk?
-W0 doesn't work.

No, you don't need a separate partition. You have enough memory and if it
went to the end, you can always create a empty file run mkswan on it and
use it with swapon /file. But with 896MB RAM you may live a long time
without it.

Removing mail completely isn't a good idea. But on a host, where you only
send mail, not receive it via smtp, you can disable the mailer damon. It
is invoked by your mail client.

If you need a mailer damon, but not very often, you can start it with
inetd on demand. This saves time while booting.

Do you know why it is for i386 nearly the double of cpu clock? Or reverse,

I found a statement to this in /usr/share/doc/HOWTO/en-txt/BogoMips.gz.

What did change in kernel version 2.2.14 is the CPU state setting just before
the BogoMips calculation. This affects the BogoMips rating for all Intel and
AMD Pentium variations, resulting in approximately 2*clock, where these were
not 2*clock.

But I found there a PPC should have the double too:
   PowerPC G4/500  992.87  K. Gustilo <[EMAIL PROTECTED]>  
   PowerPC G4/500  996.64  Heinz Nabielek <[EMAIL PROTECTED]>

   PowerPC G4/999 1992.29  Paula <[EMAIL PROTECTED]>
   

Are these wrong values or did something changed in the calculation?

Is this a kernel or a hardware problem? I saw Centrino CPU scaling down

problems playing wav with xmms

[Joerg Sommer]

Hi,

when I play wavs or use the AudioCD Reader with xmms I get no sound. I
hear only a hum and scrape, but no sound. This is with oss and alsa
output plugin.

Does anyone have the same problem? Could you solve it?

xmms: 1.2.10-2
kernel: 2.6.9 (with sleep patch)
$ cat /proc/cpuinfo 
processor   : 0
cpu : 7455, altivec supported
clock   : 606MHz
revision: 3.3 (pvr 8001 0303)
bogomips: 610.30

cd support for iBook G4

[Joerg Sommer]

Hi,

I've an iBook G4 (combo drive):
$ cat /proc/cpuinfo 
processor   : 0
cpu : 7455, altivec supported
clock   : 606MHz
revision: 3.3 (pvr 8001 0303)
bogomips: 610.30
machine : PowerBook6,3
motherboard : PowerBook6,3 MacRISC3 Power Macintosh
detected as : 287 (iBook G4)
pmac flags  : 001b
L2 cache: 256K unified
memory  : 256MB
pmac-generation : NewWorld

I can't read cds with cdrdao. It reads 9 second, sometimes 19 of the cd
and then hangs. Some seconds later the kernel reports:

ide-pmac lost interrupt, dma status: 8480
hdc: lost interrupt
hdc: status timeout: status=0xd0 { Busy }
hdc: status timeout: error=0xd0LastFailedSense 0x0d 
hdc: DMA disabled
hdc: drive not ready for command
hdc: ATAPI reset timed-out, status=0x80
ide1: reset timed-out, status=0x80
hdc: status timeout: status=0x80 { Busy }
hdc: status timeout: error=0x80LastFailedSense 0x08 
hdc: drive not ready for command
hdc: ATAPI reset timed-out, status=0x80

After this, cdrdao eats up my cpu. But cdrdao doesn't come to an end. The
time counter stays, but the file size grows, but very slowly. To read the
cd would take more than two hours (estimated).

When I kill cdrdao and run cdda2wav after, the hole system hangs and I
must do a reset.

After the kernel has reported it disables dma, hdparm still reports dma
is enabled. Is hdparm only a simulation?

I've also problems with burning cds. The speed is seldom more than 8
times and at most 12 times, but I never reached 24 times, what the
hardware should support.

Has anyone better experiences with the cdrom in the g4 ibook?

Jörg.

At which backlight level? I'd never reached four hours with my new ibook

to three, but never four. But I use 12 as backlight level and the level
can increase / decrease the time very heavy.

This was how I tested it. Now I hit a key many times and the trackpad

instruction cache throttling

[Joerg Sommer]

Hi,

inspired by John Steele (<[EMAIL PROTECTED]>,
) I searched a little bit with google
and found that the instruction cache throttling register is named in the
Kernel source (include/asm-ppc/reg.h). A todo note is made in
arch/ppc/kernel/temp.c.

I here next semester a lecture about kernel hacking. My idea is to
implements the instruction cache throttling register in this lecture. Are
there any plans to do this? Should there be a new node in
/sys/devices/system/cpu/cpu?/ to control the contents of the register? Is
there any similar at any other platform?

Jörg.

Yes. You need xkbset to switch on Pointer_Buttons for xmodmap.

xkbset m
xkbset exp =m

Afer this, you can do

xmodmap -e "keycode 113 = Pointer_Button2"
xmodmap -e "keycode 109 = Pointer_Button3"
xmodmap -e "keycode 117 = Pointer_Button3"

BTW: If the fn-Key would be visible in user space I could be used for
this.

iBook G4: Mouse pointer jumping

[Joerg Sommer]

Hi,

I would say, since my update from 2.6.9 to .11 my mouse pointer jumps
from time to time. Sometimes I can correct this with going to sleep and
wake up, but not every time. Because I have the problems in MOL too, I
think this problem liven in kernel.

Has everyone else ever seen this problem? You can't really control the
touchpad, the pointer jumps wild to and from and walk around when you
away from the touchpad. This is really crazy.

Here is the hack http://www.minet.uni-jena.de/~joergs/ictc/. I don't know
if its correct, but it doesn't make the kernel oops.

I used this module today and I don't see any difference to the life
without. I use 254 because 255 cause very high cpu load.

Interesting. I would say my cpu doesn't get hot as normal. But I'm not
sure.

How do you set the ictc? With a value of 254 and 600MHz I play mp3s
with load nearly zero. Because this I think my module do not work.

Do you have any lines of code?

I took the false values. It is not only putting the value into the
register. To enable ictc bit one of the register must be enabled.
Unfortunately I tried powers of two. :-( Now with 15 (divider = 10) it
works and the system behaves like a slower system. Playing a mp3 with
xmms consumes nearly 50 percent of cpu.

But I observed a higher power consumption. I don't know why.

Where?

In the IBM document I read you need to set HID0[DPM] = 1. I don't know,
if this is currently done.

Do you know how to read the ictc register in OSX?

How? I think ICT is useful to reduce power consumption and increase time
working with battery.

How do you measure the power consumption? I look at /proc/pmu/battery_0,
but unfortunately there are only values when running without power
connection (discharge battery).

Battery charge cycles

I have a G4 too, but I found the document before with google.

How system clock calibration is done after switching the frequency in
pmac_cpufreq? We need to adjust the clock after changing ICTC too. My
clock drifts away.

I thought pbbuttonsd counts the cycles itself. Can pbbuttons tell me the

clock drift

[Joerg Sommer]

Hi,

I've an iBook G4 and I observe a clock drift. I don't know if it is new
or there for longer time.

#v+
$ ntpdate -q server; sleep 5; !ntp
ntpdate -q server; sleep 5; ntpdate -q server
server 192.168.0.1, stratum 2, offset 1.169256, delay 0.02589
25 May 13:26:31 ntpdate[31805]: step time server 192.168.0.1 offset 1.169256 sec
server 192.168.0.1, stratum 2, offset 1.170198, delay 0.02589
25 May 13:26:36 ntpdate[31811]: step time server 192.168.0.1 offset 1.170198 sec
#v-

I update my clock with ntpdate -B everytime the interface comes up. This
means after every sleep ntpdate is run. Because this I didn't see every a
big clock drift like some minutes, but the drift above means 16 seconds
per day, which is really heavy.

Does anyone know where this drift comes from? Is it caused by the time
while waking up or going sleep.

I experienced the same problem at me with a 2.6.6 kernel. If the lid is
closed a unknown period the ibook powers off. The G4 doesn't support
sleep-mode currently so the backgroud light is only switched off. But
maybe there is a piece hardware which powers off the iBook if the lid is
close too long. I have also the presumption that this only happens if it
runs with battery, but I'm not sure.

Does anyone else experienced this? Is there a solution?

I wouldn't say its caused by pbbuttonsd, because I suppose pbbuttonsd
shutdown the system cleanly and not call halt -f. I don't think it is a
problem the system is shut down, but is should happen cleanly (unmounting
all filesystems).

current power consumption

[Joerg Sommer]

Hi,

is it possible to get the current power consumtion from
/proc/pmu/battery_0?

$ cat /proc/pmu/battery_0 

flags  : 0013
charge : 3789
max_charge : 3930
current: 195
voltage: 12650
time rem.  : 2603

I've measured a power consumption of 24 Watt, but I don't know where to
find this in values above. What are the units of the values above? Is
charge and max_charge in Ah (Ampere hours) and voltage in mV? Why current
is 0 if the battery is full? The laptop still consumes power.

Bye, Jörg.

Which part of the manpage says what's the meaning of -8. And, well, the
manpage negates the existence of -8.
