That's not selling a different What I meant was: First revisions may have had incomplete OHCI 1.1 support and were sold as OHCI 1.0 chips, and as soon as they stabilized it they sold them as OHCI 1.1 chips. But that's mere speculation on my part. I can't think of any other reason though why anybody would hide OHCI 1.1 compatibility. > Anyway, I just connected a programmer to the EEPROM (machine "a" in my > previous mail = EPIA-M 600 MHz), wrote "8" to the 16-bit word at address > 0x11 (93c46 EEPROM), and now this VT6307S dated 0239CD (2002, 39th week) > says: > ohci1394: fw-host0: OHCI-1394 1.1 (PCI): IRQ=[12] MMIO=[de000000-de0007ff] > Max Packet=[2048] IR/IT contexts=[4/8] And are you going to test if and how stable OHCI 1.1 features work? (Which features are these? Right now only dual buffer reception comes to my mind.) -- Stefan Richter -=====-=-=== =-=- =---= http://arcgraph.de/sr/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
