With that amount of knowledge you have about your card, it actually
shouldn't
be to hard to develop a driver. I wrote a linux kernel driver for a
volume rendering
graphics card with reconfigurable hardware and an onboard DSP with less
information.
I don't know about the interna of your HPI, but surely you need to
include some low level
code to do the PCI detection and setup of your card with linux. If
that's already in your
HPI it shouldn't be a problem to adapt that to write a wrapper for the
alsa lib.
If you want then you provide your dsp code and distribute it with alsa.
At least some amount of code
goes into the kernel and so has to meet Linus standards :-)
Alright, then. If you have any questions, I see no problem supporting
you, writing that driver.
Cheers, Alex
