Right, but that was the *only* case where multi-packet DMA RX could realistically be used. And you couldn't actually know if a given request came from mass storage. > And on the > OMAP-L1x, you can use the new "generic RNDIS" mode with the programmed > transfer length (and AutoReq feature, of course). Sounds better. Of course, the older "RNDIS" mode wasn't actually fully conformant with RNDIS specs, or it could have been used for all transfers. All RNDIS did was follow the DMA policy that (non-UHCI) PCI based host controllers use to avoid extra IRQs. - Dave _______________________________________________ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
