I think the patches sent out from ST-Ericsson's Johan Mossberg to linux-mm for "HWMEM" (hardware memory) deals exactly with buffer passing, pinning of buffers and so on. The CMA (Contigous Memory Allocator) has been slightly modified to fit hand-in-glove with HWMEM, so CMA provides buffers, HWMEM pass them around. Johan, when you re-spin the HWMEM patchset, can you include linaro-dev and linux-media in the CC? I think there is *much* interest in this mechanism, people just don't know from the name what it really does. Maybe it should be called mediamem or something instead...
