> I can confirm Mark's observation that the access speeds are slower - around half the speed of the earlier Linux PIO driver, and a quarter the performance of WinXP. Test CF card was a SanDisk UltraII as the target, with CB1410 (Yenta compatible TI clone) as the host CB32 controller. > > The driver works, but appears to use PIO only (PIO 4 is reported, actual performance is nearer PIO 0) > Should the UDMA modes of the CF be usable? Due to lack of documentation - not at the moment. Even the BSD folks haven't managed to get that bit going. Pulling the card registers for the device in Windows PIO4 would be most useful. > Linux throughput of 'dd bs=100MD' writing to FAT16 (Dell 3GHz P4 x86 32bit, kernel 2.6.23): > > 3.1MB/sec for Linux PCMCIA (legacy delkin_cb.c ) > 1.8MB/sec for Linux CardBus 32 (libata pata_ninja32.c) Yes. I've not had time to go back and do more investigating.
