After a bit of positive testing, I committed a linux1394 git patch plus David's dynamic buffer alloc patch, which is about to be in linux1394 git, to the rawhide kernel. We've now got working iidc streaming on all OHCI 1.0 and 1.1 cards, so far as I know. I'll see about back-porting these bits to the F7 and F8 kernels as well. Would definitely like to hear what *doesn't* work now, short of dv capture with Via VT630x OHCI 1.0 cards, which is known broken and under investigation. -- Jarod Wilson jwilson@xxxxxxxxxx
