It is not the onboard sound card that works but the pci sound card.


No worries.
I do know the onboard system works so just waiting for the Amiga drivers.
As for installing Deb, you just would not believe how fast I can mess up a whole system while tinkering around where my fingers probably don't belong. My fingers, my computer. :D
And, most times I learn something interesting. So it's worth it.

Besides, crashing a computer doesn't hurt as much as crashing my bike. :shock:

In my effort to get SBLive emu10k1 working with Deb (squeeze 6.0.5) without omitting the PAsemi IOMMU in the kernel build I tried doing some rookie hacking.

The problem is that the memory window is too large for 32 bit DMA that uses 0x7FFFFFFFF for a mask value and initialization of the card fails. What I did is change the value for the iommu_table_iobmap.it_size from 0x80000000 to 0x7FFFFFFFF in the file /arch/powerpc/platforms/pasemi/iommu.c .

It may not be the right thing to do, but it worked. No more DMA window error.

There also seems to be....not a conflict, but a contention for which sound source/card will have use of system resources on squeeze. Not including the intel HDA stuff in the build, the SBLive started to perform flawlessly, even though it was recognized and I was able to tell alsamixer was indeed seeing and able to control it with only the DMA change.

Would be nice to have a kernel guy look at this and some of the other warnings that pop up during build.

Good to know. Thanks.

I will most likely do more with Linux in the near future.

I have been messing around with getting a grip on Xena and tinkering with some other Amiga software and of course trying to increase my understanding of the X1000 hardware.

Just not enough hours in the day.
