Support for powermac G5?

Support for powermac G5?

[jaspal.kallar.xfree86]

Can anybody say if sound on the powermac G5 is supported ?
I have no idea which chipset it is either.

I've tried with kernels 2.6.5, 2.6.6 and 2.6.7

modprobe snd-powermac
FATAL: Error inserting snd_powermac 
(/lib/modules/2.6.7-r0/kernel/sound/ppc/snd-powermac.ko): No such device


and in /var/log/messages I get

"Jun 20 18:19:09 linux ALSA sound/ppc/pmac.c:1095: pmac: can't request resource 0!
 Jun 20 18:19:09 linux no PMac soundchip found"


Can anybody give me some pointers into what the problem could be. Btw I 
have snd-powermac as a module and not compliled into any of the above kernels.
But I have also tried it compliled into the kernel but with same results.

Dont't know anything about soundchips on G5, but on my new Powerbook I 
had to comment out the chipset identification in pmac.c and set the chip 
to snapper.

Reiner: I presume your commnets are for the function (pmac.c): 
"static int __init snd_pmac_detect(pmac_t *chip)" 

where you commented out the if-statement (line 927 for me) :

if (device_is_compatible(sound, "snapper")) {
                chip->model = PMAC_SNAPPER;
                // chip->can_byte_swap = 0; /* FIXME: check this */
                chip->num_freqs = 2;
                chip->freq_table = tumbler_freqs;
                chip->control_mask = MASK_IEPC | 0x11; /* disable IEE */
}
 
so that it was snapper. A question though. How did you know that you had 
to set the chipset to snapper ? Was this information available somewhere 
in /proc ? For example, (wild guess) is the information in  
/proc/device-tree/ht@0,f2000000/pci@3/mac-io@7/i2s@10000/i2s-a@0/sound/compatible
important ? In my case it gives AOAK2.

Also did you get the same error as me i.e 
"ALSA sound/ppc/pmac.c:1095: pmac: can't request resource 0!"
in /var/log/messages?

Thanks,

Jaspal.

Yes, that's what I did.

It says here: AOAKeylargo
I don't really know much about these things. I read about this 
work-around on the debian-ppc mailing list (This list has been very 
helpful in resolving a couple of issues with the new powerbooks).

Yesterday I updated my kernel to 2.6.7-bk9 and I didn't have to modify 
pmac.c any more. So for powerbooks this seems to be fixed.

No, I haven't seen that.

Reagrds,
Reiner
