I'm planning to commit the bus space code(*) supporting indirection
into current for PC-98. As far as I know, only PC-98 needs
indirection. So, it will be enabled only when the `PC98' is defined
to avoid performance loss on IBM-PCs.
(*)The code is submitted by Takahashi-san <[EMAIL PROTECTED]>.
My plan is as follows:
1. copy sys/i386/include/bus.h to sys/i386/include/bus_at386.h
2. put sys/i386/include/bus_pc98.h into the sys/i386/include
directory.
3. Make new sys/i386/include/bus.h file as:
#ifdef PC98
#include <machine/bus_pc98.h>
#else
#include <machine/bsu_at386.h>
#endif
4. Make new file bus_pio_ind.h. This file only defines
_I386_BUS_PIO_IND_H.
New functions isa_alloc_resourcev() and isa_load_resourcev are added
to support indirection in isa.c. Also, nexus.c is modifed. I'll fork
these files int sys/pc98/pc98 and sys/pc98/i386.
Is there any comments?
