Hi Grant,

I'm assuming inb() outb(), inw() outw()?? I've been googling and have
come up short with info that makes sense. It is almost all x86 centric.
in_8, in_be16, in_be32, out_8, out_be16, out_be32 for big-endian
device registers
in_8, in_le16, in_le32, out_8, out_le16, out_le32 for little endian
device registers
We will not be porting these drivers, this is a captive box internal use
only, limited run (200 units or so), 10 to 20 year lifespan once it hits the
field.
So, the virtual address I get back can be used directly. Can I cast to
short * and long * and char *?
heh, yes you can; but if your writing new code why not use good
practice from the start? :)
I apologize for the basic questions, but I expect this will be a final
question for quite some time.
No worries; ask away!
Cheers,

OK. I'm breaking my promise. :) A couple more questions.

Execution of Input/Output) for me, or do I have to do that? I'm still
confused as to that Old MacDonald function.

THANKS AGAIN!!!!

The in functions do isync
The out functions do eieio

read include/asm/io.h. All the IO routines are defined there.
read[bwl] and write[bwl] are just macros to in_* out_*, as are inb,
outb, etc.
