Hmm, how do they come up with these numbers? I thought these latencies were in PCI clock cycles. Since the PCI clock is 33MHz, one cycle is 30ns. Thus, 128 cycles would be 3840ns, and 38 cycles would be 1140ns...? > Min Latency is the minimum latency necessary for the SAA7146 to send all > data off from his queue and max latency is the maximum latency until to > be in turn again before the queue of the SAA7146 gets an overflow. I don't understand :( What is the "minimum latency"? The "Latency: 128" number above? And what does the "Minimum Grant" number mean? more confused than enlightened, -- Robert Schlabbach e-mail: [EMAIL PROTECTED] Berlin, Germany -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
