No, because the mm maintainers corre
mapped in user space, my buffer can be safely used by
both CPUs and GPUs and that the VM will never swap it?

Thanks for the answer
I actually have no a rather simple prototype doing shared memory between CPU
and GPU. Basically:
1/ I create a buffer B
2/ I map B and get a pointer to it
3/ I exec a batch buffer with B
functions. However, I am not sure I can get symbols from i915 properly. Is a
i915 patch the only solution?

Now it's under limited use for the buffer that is sure to be cached,
e.g hw status page, etc. code lives in drivers/char/agp/in
