Hi,
Question for PCI gurus: Is:
void mybcopy( char *from, char *to, int amount) { while ( amount-- ) *to++ = *from++; }
guaranteed to perform byte transactions on a PCI device? (The device at hand doesn't support non-byte tranactions)
"to" is probably on the PCI device, while "from" is usually in main memory, but might be cached closer to the CPU....
Roger.
