And they asked for hardware donation and possibly some monetary incetive (not sure about this one though), in order to get the pegasos supported, even though we made all the work. They seem to be considering dropping powerpc anyway. http://www.linux.com/article.pl?sid=06/11/16/1443243 According to the PowerPC review spec, only 0.8% of downloads from archive.ubuntu.com are for the PowerPC architecture as of November 2006, down from 1.95% in July 2005. Ubuntu founder Mark Shuttleworth and Ubuntu CTO Matt Zimmerman each indicated that dropping official support for Ubuntu's desktop install on PowerPC was on the table. While demand for PowerPC is declining, the work required to keep the port current remains steady. Lack of official support doesn't mean that PowerPC support would go out the window entirely. If demand for PowerPC server installs remains steady, it could be maintained as an unofficial port and moved to ports.ubuntu.com. -- Paul Collins Wellington, New Zealand Dag vijandelijk luchtschip de huismeester is dood -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Re: PowerBook G4 (5.9) Debian Sound problem

The problem is that the Gnome System sounds are working but all other sound like mp3, DVD sound or radio streaming don't. Sometimes I just get a noise and sometimes just nothing. I also have a constant low noise from the speaker all the time. First I thought it's from the harddisk but its from the speakers. I don't know about the second problem, but the first could be caused by DRC (dynamic range compression) -- those event sounds are short enough that it mightn't trigger for those. To check if this is the case, look for the DRC Switch slider in your ALSA mixer program and either crank it up to 100% or mute it to disable DRC. -- Paul Collins Wellington, New Zealand Dag vijandelijk luchtschip de huismeester is dood -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

One thing I would want to add is support for finding the address and bus directly via open firmware instead of that stupid 4..260 loop, you may look at http://git.sipsolutions.net/of-lib.git/ for a WIP library to access the device-tree. I was able to use this code to find the lmu-controller node and read the address from 'reg' - looks like it's the value shifted right one bit. (An old posting[1] does it similarly.)

No, you'll probably need to do of_find_compatible_node(NULL, NULL,
lmu-controller) or something like that, if your compatible property
includes 'lmu-controller' too.
Hmm, no of_find_compatible_node or anything like it that I can see in
the of-lib I pulled today. And delightfully there doesn't seem to be
any 'compatible' property in my lmu-controller node.
Anyway, here's the current version with the sysfs-guided I2C probing.

Otherwise you'd also have to manually load snd_aoa_fabric_layout and possibly snd_aoa_codec_tas or so. If you had them installed the MODULE_ALIAS(sound-layout-51); should have made it load automatically. Yep, I did make install after the build. And modinfo /lib/modules/`uname -r`/kernel/sound/aoa/snd-aoa-fabric-layout.ko shows ones of the aliases as sound-layout-51. I did a fresh boot with snd-powermac renamed out of the way, and now I get even less action: nothing logged in dmesg, and when I unload all five modules and probe snd-powermac (having renamed it back) I get May 20 01:08:29 briny kernel: snd: can't request rsrc 0 (Sound Control: 0x8001:80010fff) Then when I removed snd-powermac and probed i2sbus I got the same May 20 01:10:00 briny kernel: i2sbus: mapped i2s control registers May 20 01:10:00 briny kernel: i2sbus: control register contents: May 20 01:10:00 briny kernel: i2sbus:fcr0 = 0x0 May 20 01:10:00 briny kernel: i2sbus:cell_control = 0x0 May 20 01:10:00 briny kernel: i2sbus:fcr2 = 0xb7f53c May 20 01:10:00 briny kernel: i2sbus:fcr3 = 0x0 May 20 01:10:00 briny kernel: i2sbus:clock_control = 0x0 May 20 01:10:00 briny kernel: layout id is 51 May 20 01:10:00 briny kernel: i2sbus control destroyed Probing snd_aoa_fabric_layout and snd_aoa_codec_tas yielded no further dmesg output and /proc/asounds/cards remains no soundcards. -- Dag vijandelijk luchtschip de huismeester is dood -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Re: 2.6.17-rc3: cpufreq-set -g ondemand does not work
Bernhard Reiter [EMAIL PROTECTED] writes: but my idea would be that an ondemand govenor would just work on a load average with some delay to even out spikes. The userspace governor combined with powernowd will give you this. And since the userspace governor defaults to the lowest CPU frequency, it all works out nicely. I've using it happily on my PowerBook. -- Dag vijandelijk luchtschip de huismeester is dood -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

Re: 2.6.16-1 hyper logging

Dev: powermac/beep, Type: 18, Code: 2, Value: 0 Quite 20 lines per second ! Is there a var to change via /proc/sys or is it necessary to recompile the kernel with less logging ? It looks like the evbug module is loaded, which is designed to do exactly this.

Re: 2.6.16 backtrace at boot (Ibook G4) (related to PowerBook5,4 -- no sound?)
Hi Ben, Benjamin Herrenschmidt [EMAIL PROTECTED] writes: On Tue, 2006-04-18 at 17:20 +0200, Michael Schmitz wrote: Here a trace at boot from the sound driver : I think that bug happens if the sound driver loads before i2c-powermac. i2c-keywest is still request-module()d in 2.6.17-rc1, FWIW. Regarding other sound breakage with 2.6.17-rc1, I traced that to machine_is(powermac) returning zero in sound/ppc/pmac.c:snd_pmac_detect() when loading snd-powermac. The OSS driver spits -ENODEV as well on loading so I'd suspect the same thing here. machine_is boils down to a comparison machine_id == mach_powermac, is that sort of thing illegal after kernel init? Totally untested patch, please let me know if it helps: Results in the following. arch/powerpc/platforms/powermac/setup.c:721: error: 'mach_powermac' undeclared here (not in a function) arch/powerpc/platforms/powermac/setup.c:721: warning: type defaults to 'int' in declaration of 'mach_powermac' make[2]: *** [arch/powerpc/platforms/powermac/setup.o] Error 1 make[1]: *** [arch/powerpc/platforms/powermac] Error 2 make: *** [arch/powerpc/platforms] Error 2 It looks like the EXPORT_SYMBOL() needs to be after the definition. However, I tried adding EXPORT_SYMBOL(mach_powermac); after the define_machine(powermac) and now sound works for me with my original I2C_POWERMAC=y SND_POWERMAC=m configuration. -- Dag vijandelijk luchtschip de huismeester is dood -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
