Sharing DRM buffers across process

Hi,

I need to share DRM buffers across 2 processes. I am allocating  Bo using omap_bo_new API.

In my current implementation I am allocating omap_bo in one process and updating its content. From the second process I am referring to same omap_bo allocated in the previous process.What I have observed is mapped bo content is always having some  junk values.

Is this the right method for sharing DRM buffers?

Any suggestions would be greatly appreciated.

Thanks in advance
