GEM is actually pretty sane when you get your head around it a spot. The main thing it took me a bit of time to get my head around is that it allocates backing memory and handles but it doesn't allocate address space on the card side.
I'm not sure I understand you correctly. I have no address space on the card side since my 'card' just uses main memory. The memory I need must be a physically contiguous portion of sdram. I'm afraid shmem backing memory is not of much use for me.
Correct me if I mix things up...
