2.6 Kernel , Xilinx Virtex and PPC 405 On chip memory controllers ( DSOCM and ISOCM )

Hi all,

Just a very simple question about the 2.6 kerenl,

suppose that in my base system I have included 8kbytes of memory for DS OCM=
 and 8K for IS OCM,
I have generated the proper xparameters.h and copied it into kernel

Now I want to know if kernel will use this portion of memory during it's op=
eration?
Does this increase performance?

thanks

No, it won't use that memory as general purpose RAM.  You can make use
of it in device drivers (ie. for DMA space), but you'll need to write
the code to support it.

Cheers,
