Hi Marek and Laurent,
I am working on v4l2 drivers for blackfin which is a no mmu soc.
I found videobuf allocate memory in mmap not reqbuf, so I turn to

I found videobuf allocate memory in mmap not reqbuf, so I turn to videobuf2.
But __setup_offsets() use plane offset to fill m.offset, which is
always 0 for single-planar buffer.
