Hi,
After some days browsing for info, it looks like I'm being unable to
tune my IRQs to get my sound card on its own, exclusive IRQ.
I'm using 2.6.21.3-rt9 on Debian Etch now, but:
a) sound card is on IRQ 17 with ehci on IRQ 17 too. Both sound card
(intel hda) and usb are motherboard (NVIDIA CK 804) ones. I'm not
getting xruns, and I was thinking it was quite fine and probably
hardware-related.
b) However, I can not get those nice 255 IRQ vectors even if local apic
and io-apic on uniprocessor are active. I even tried to use debian
kernel configuration as much as possible (on 2.6.18 I get the vectors)
but they seem to be unavailable as soon as I patch the kernel with
Ingo's patch.
So I think now this could be software-related and I would be able to set
IRQs. What's the matter? Could you guys give me some up-to-date pointers?
Thanks
Roman
