MPMC-VFBC driver in linux

Hi,

 

I made a core attached to a mpmc memory controller by a vfbc interface. This core is a frame grabber which is connected to a cmos censor. I made a program in standalone version in edk and everything works fine. This core is intended to be used in a linux environment.

 

So the vfbc writes data frames in fixed locations in memory, that means, physical memory. My questions is:

 

How can i read this data frame in a linux user space aplication?

 

What about virtual memory and  MMU constraints?

 

What kind of driver: Block, DMA?

 

I alredy have a running linux system:

 

Virtex 4 Fx's PPC405 processor running Linux  kernel 2.6

64MB DDR2 SDRAM attached to a MPMC controller

 

Any one who can give me a hint or put me in the right direction to acheve this?

 

Thanks in advance.
