    POPSHM, RCCE shared memory - how to set page table flags?


      Hi there,


      We are trying to play a bit with sharing the off-chip memory between the cores, but there are a few things we haven't been able to figure out easily:

      1) When using POPSHM, or the shared memory API provided by RCCE, what is the default memory mapping used? I guess it's cached non-MPBT but just to check.

      2) Is there an easy way to change the mappings without having to hack the kernel? What do you propose?
