Subject: Re: [Linaro-mm-sig] [RFC 1/2] dma-buf: Introduce dma buffer sharing mechanism

I've rebuilt my PRIME interface on top of dmabuf to see how it would work,

I've got primed gears running again on top, but I expect all my object
lifetime and memory ownership rules need fixing up (i.e. leaks like a
sieve).

http://cgit.freedesktop.org/~airlied/linux/log/?h=drm-prime-dmabuf

has the i915/nouveau patches for the kernel to produce the prime interface.

Dave.
