I posted the patch to some lists. The patch does:
1. change the type of bus_space_handle_t into the struct in PC-98
source.
2. Add new bus space tag, I386_BUS_SPACE_IND.
Warner told me that some drivers assumes that the type of
bus_space_handle_t is integer. This makes it impossible to compile
some driver.
I think this assumption should be fixed, but it may
require hard work. I think following function can hide the problem:
IBM-PC:
inline void
bus_simple_create_i386_io_map(bus_space_handle_t *bshp, u_int16_t port)
{
*bshp = port;
}
PC-98:
inline void
bus_simple_create_i386_io_map(bus_space_handle_t *bshp, u_int16_t port)
{
bshp->bsh_base = port;
}
How about this?
