Hello Everyone,
I'm looking for some information about the Extended Addressing
Mode (XAEN bit of HID0 register) of PPC32 support in Linux.
I do not see anything in the main kernel tree but there may be
some patches available ?
Any information will be appreciate.
Regards.
There are patches from Becky Bruce that are going into 2.6.28.
What are you needing >32-bit for? There are some SW IO MMU changes
that are still pending to complete this work.

We are developing a board based on Freescale 8641D which can get 4GB
of ram. So I need 4GB+IOs (~1GB) of physical addressing space.
My plan is to put a part of this ram above of 4GB to keep accesses
to the IOs below the 4GB limit. It means non-contiguous ram
addressing and XAEN features to be working.
So we have XAEN support in the tree.. however non-contiguous is
something you'll have to work on yourself. Patches are welcome for this
Where can I glance through Becky patches ?
This is the bulk:
