rme and also put the
rme96.c in it or put it in the pci/ folder.
- is there a place to put the hdspm test-apps and docu somewhere ?
or should I setup a own page for it (wiki) ?

its safer to use
io_extent= pci_resource_len(pci,0);
(in the hdsp_createfunction instead of giving a fix one.)
3) should we change the the hw_params so that only needed channels are
enabled (and change the ruleset to it) ?

Thanx that cleared a lot.
So I managed now to put it in hw_params and it works in some way.
needed an additional
There is one point I found:
- when I preallocate with for playback and capture
2*4194304 = 8388608 Bytes:
snd_pcm_lib_preallocate_sg_pages_for_all(hdspm->pci, pcm,8388608,8388
;dma_private;
is not assigned.
but when I activate the card (for MIDI for example) there must be
memory asigned und I think doing it in hw_params is to late.
2) If it is bound to substream is always the same substream the
capture or playback or are the assigned dynamically on calling ?
