That would be me. I looked at the VHDL for the hardware. The registers seem to be aligned to 8 bytes but only use the LS byte of each. So it probably doesn't matter whether the memory transactions are 64-bit or 8-bit. I know the hardware doesn't support byte-enables either, which is probably why the registers were padded this way. Probably also why the inb_p and outb_p macros were redefined. >Probably a separate issue, but I did notice it as a result of this patch. > >Thanks, >Geordan _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
