about how to start on hwdep implementation.
Please take a look at snd_emu10k1_fx8010_ioctl in alsa-kernel/pci/emu10k1/emufx.c for examples of hwdep ioctl usage.
that wasn't too hard. I have implemented stubs just to see how it fits together.
It doesn't do quite what I want. The existing HPI ioctl has one device file for the driver, whether one or sixteen cards are installed, and its name doesn't change depending on the card index. (I.e. userspace accesses the whole (HPI) audio subsystem through the one /dev/asihpi)
ALSA makes one device file per card, and the file name depends on the card index. Is there any way I can make a single device for the driver that has an unchanging name (preferably /dev/asihpi)
