The newbus routines use a certain amount of overhead, but once done, you
forget about it. In some device drivers, the probe methods often need to
try a variety of hardware ports. In the past, inb/outb was used, along with

One more question:
In the probe routines, the values of the hardware ports are changing from

Any devices using the ppbus will end up sharing the hardware port. If i want
to access this resource info, should i store it in my local driver's softc
structure, or extract it from the parent device (ppbus)?

I'd like to finalize the newbus work by changing inb()/outb() calls to

I'm new to hackers, but I'm trying to tackle a couple of bugs in the

which is much faster on reads.
I have 2 questions:

None of this will be source level, correct? Will it at least have labels if

I've used softice for debugging under windows, and i was wondering if gdb
offers similar capabilities. It seems the best way to debug the ECP
parallel port problem is to step through the code during the boot phase.
Can this be done, or is there too much timing-critical stuff going on then?

I just realized i think this machine may not have that part of the source
installed.
Also, the ppc code is even more complex than the ppbus stuff. I don't know
how much good i'll be able to do. Does anyone have any ideas on figuring

I'm trying to trak down why ECP doesn't work undder 4.0. So, far, i can't

Apparently, you make a floppy with the supplied image, boot with it to
