Linux on PPC tools

In order to ease testing and usage of the stuff on this page, I set up my own little deb-file repository for apt. Just add the line

		deb http://cedric.pradalier.free.fr/ibook2/ ./

to your /etc/apt/sources.list, and you should be able to access my small package list.

Don't forget to report problems, but also successes.
Thanks and Welcome

A kernel patch for accessing the thermal control chip on ibook2.2 (linux kernel >= 2.6.4).

Note: From kernel 2.6.8, lm-sensors modules support adm1030 chip. So I think there will be no longer need for the adm103x module, but I still use it...

From 2.6.8, I added some ioctl access to the driver. If udev don't handle this automatically, create the /dev node with:

			(for module <1.2.4) mknod /dev/adm103x c 63 200
			(for module ≥1.2.4) mknod /dev/adm103x c 10 131

How to setup the therm-adm103x driver

Install the patch. Go to /usr/src/linux-2.6.x and run patch -p1 < path/to/adm103x-2.6.x.diff.
diff with 2.6.14
diff with 2.6.15
diff with 2.6.19.2
adm103x.tar.gz: complete sources of the independant module.
To see if thermal control is done by the chips that this module can manage, just check that
```
			#cat /proc/device-tree/uni-n*/i2c*/fan*/device_type
			
```
returns adm1030 or adm1031.
This driver provides some thermostat monitoring for ibook2 rev. 2 (ibook2 is not sufficient), equipped with a adm103x fan control chip. It also provides and sysfs access to the adm103x fan control parameters. For instance
```
			  #cat /sys/device/temperatures/info? 
			  T:51°C S:56°C R:10°C  <-- sensor 0
			  T:48°C S:76°C R:10°C  <-- sensor 1
			  #echo "56 10" > /sys/device/temperatures/info0 
			  
```
make the fan starts at 56 degrees and accelerate progressively till max at 66 degrees (56 + 10), on the sensor 0.
New : a dockable app which monitor the sensors state.
The admctl package contains a text utility (admstate) which displays and interpretes all adm1030/adm1031 registers. In the same package, admstate-ioctl uses the ioctl interface of the driver to display the same information.
With new version of the patch, displayed temperature is real temperature with offset removed and full resolution. Starting fan temperature can be set to any integer value.
On my ibook, I used 56° and 60° for first version of the patch (52° and 52° with offsets removed). I now set general temperature limit to 54° and CPU limit to 50°.

Since version 1.4 of the dockable application, a middle click on the window check if the fan is still needed and eventually switch off the fan. This needs the ioctl capable driver (version > 1.2).

A ybin version (based on yaboot 1.3.11 code) which checks yaboot.conf syntax before installing boot partition.

The ycheck binary is just a call to the yaboot config reader with prom_printf replaced by printf. So when ycheck is ok, it means that yaboot will be able to parse the config. I just add 3 lines to make the test on ybin.
This is not a patch since yaboot authors is working on yaboot 2.0 with improved syntax checking.

Install : make and copy files where you want to access them.

A modernized version of ical (an old calendar/schedule utility)

The tar.gz : here
The debian package for linux ppc : here
Modifs : easiest compilation, roll mouse management, other options for the text version...
I'm not the only one to have tried to modernized ical. Please have a look to the ical maintenance project. I'm too lazy to bother to make a patch between these two versions...

A modified version of hotkeys : here

Modification :

Added ibook2.def for ibook2 keyboard definition
Make it compile without any warning with gcc-3.3.3 -Wall (added headers, removing unused, initializing variables, adding forward declarations, removing static for exported functions, added returns...)
Added support for the backlight control buttons of my ibook. In fact backlight control is managed by Kernel. But this generate an X event nonetheless, so I add a showBrightness function which catch this event and I use libxosd to display backlight status. I had to add two keys in the xml specs : BrightUp and BrightDown on the model of VolUp and VolDown.
Added a --with-pmu flag in configure.in to control if backlight management must use pmu.
