The kernel part is open and provides access to buffer management.
The Imagination driver has a sort of texture streaming extension. That
allows you
to attach special shared memory buffers, that were allocated by for the GPU.
TI added a so called buffer class as a loadable module [1], to manage
the buffer allocation. All in all maybe not enough to implement proper
sharing of
buffers, but maybe it can be abused somehow....
