Hello,

I am writing an RTDM driver to replace one that uses UIO. The device
resides in a physical address > 4 GB on a PPC440EPx. The UIO could
not handle this address so I made a proposal to address it, details at:
http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-April/070097.html

Function rtdm_iomap_to_user() has same issue with the physical I/O
address
   unsigned long src_addr

I am new to Xenomai and would like to get some ideas on how to solve
this
issue.

Thanks,

Luis G. Herrera-Bendezu
