Cmd/mmap with realtime

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi,

I'm using a PC104-DAS16/JR with comedi-0.7.65 and comedilib-0.7.18 with an 
rthai patched 2.4.19 kernel. I would like to use cmd or mmap with realtime, 
so I set the comedi_cmd flag to TRIG_RT, but comedi tells me that it`s not 
possible to set the TRIG_RT flag while in DMA transfer mode. On the other 
hand cmd and mmap require both an IRQ and DMA... I need to use realtime data 
aquisition, because I need the full sampling rate of 100KZH which is provided 
by the board. Without realtime I get I/O errors after some time even if I 
increase the read_buffer_size. I'd appreciate any help,

Daniel Koch
