I'm working on a IEEE1394-based research project and am investigating the Linux IEEE1394 drivers. I have a tree of custom 1394 modules and need to be able to support isochronous receives from all of them. 60 channels, roughly 5Mbit/s each. Do the current Linux drivers support this? This line in the ohci1394.h file made me nervous: #define IR_NUM_DESC 16 /* number of IR descriptors */ What are the descriptors? IR is isochronous receive? Do I need one for each channel, and if so, can I just change the define and recompile? I'm new to Linux and IEEE1394, so any general comments and warnings would be greatly appreciated. Thanks, Bennett |
