Whether or not they support busses which do 8 byte atomic : reads/writes I am not sure of. : : Thanks for the reality adjustment Warner. =) Yes. Looking at the bus.h in NetBSD/i386 I see: #if 0 /* Cause a link error for bus_space_read_8 */ #define bus_space_read_8(t, h, o) !!! bus_space_read_8 unimplemented !!! #endif The Netbsd/alpha version appears to have it defined.
