No. You're confusing PV device discovery
OK, so what are we doing here? We're using a PCI abstraction, as a
common abstraction,which is not common really, because we don't have a
common abstraction? So we describe all these non-pci resources with a
pci abstraction?
I don't get it at all. I really think the resource interface idea I

Yes, the cpu flushes all of them.

You have to make QEMU use ALSA as your sound system and specify a mixer
device for input and output. This can be done using some environment
variables that should be set before the qemu binary is run.
The following may work:
export QEMU_AUDIO_DRV=alsa # the default is OSS if I recall

yes, but getting rid of them is an entirely different discussion.
I really think that in the first step, you should be able to
use its "external interrupts" with the same request_irq interface
as the other architectures.

Hi,
I saw some discussions on the topic but no progress. I did an

Hello,
I have found an issue for compiling on 32 Bit machines in
v2.6.22-rc1-g1ab29f3.
I'm not sure if I have set the #ifdef CONFIG_X86_64 at the right place.
Please have a look at it. With this patch v2.6.22-rc1-g1ab29f3 compiles
und runs fine.
