Re: little endian page mapping on PQ3

Hi, Jose!

Hi all,

Looking at PQ3 documentation, it looks like there is a way to select
on a page basis if we would like to map one particular page in BIG or
LITTLE endian.
This is a very nice feature when you need to exchange some data
between a PC and a PQ3 target.

I would be interested, however cannot spend time right now to work
on that subject.

I am wondering if someone have already tryed this PQ3 feature ?
I guess this would require some kind of hook in the kernel ...

Just some random bits I found in the web:
http://developer.apple.com/documentation/Hardware/DeviceManagers/pci_srvcs/pci_cards_drivers/PCI_BOOK.250.html

The Interesting part is:
"Thus, the address swizzle is completely transparent to software."

So, I would just try to setup some memory mapping and turn on little endian
mode to access that area... MMMV. Just a guess.
