Re: Alsa-driver compile fail on Ubuntu powerpc

Takashi,

The issue is still present with the latest alsa-driver.
Do you think that it's problem with 64 bit resource  with  pcm _mmap.
Here is dmesg :

Which one did you take?  It must be sound-unstable tree.

Anyway, you should better to use sound-unstable-2.6 git tree together
with the latest Linus tree.

Re: Alsa-driver compile fail on Ubuntu powerpc

Takashi,

I'm using the alsa-driver from git  with the latest kernel.org 2.6.26 as you
suggested me.
The issue is the same with alsa-driver stable v1.0.18rc1.

There are two different versions: stable and unstable trees.
The fix for non-coherent platforms is currently only in the unstable
version, and this can't be built externally via alsa-driver build
stub (it could, but works only for x86).

You need to build the  kernel by yourself to include some new
functions, e.g. clone the latest Linus git tree (2.6.27-rc4*), then
pull sound-unstable-2.6.git on that.

thanks,

Takashi

Re: Alsa-driver compile fail on Ubuntu powerpc

Takashi,

I'm not very familiar with git. Please feel free to help with "git pull".
I have already done "git clone" the latest kernel source 2.6.27-rc4
but I still can't merge sound-unstable-2.6.git with the kernel.

Thanks,
TaiNguyen

Re: Alsa-driver compile fail on Ubuntu powerpc

I did compile your alsa-driver-unstable using cross-compile powerpc-linnux-
in a x86 Linux.
Then, I did insmod the modules and aplay -vvv sample.wav.

The issue is the same with the old drivers.
Following is dmesg :
