Revision 1372, 10.2 kB (checked in by ppalmers, 12 years ago)

Host controller reliability changes:

  • make receive DMA mode selectable (but still hardcoded ATM). Some controllers seem to work better in bufferfill mode.
  • introduce a maximum number of ISO buffers for receive, lower the max nb of ISO buffers for xmit
  • make the number of buffers for receive and transmit a power of two
  • ensure at least two hardware interrupts per complete ISO buffer wraparound
