Hello -
I am attempting to port code that calls the gen1 function
ib_memory_register -- I saw the other posts about this issue -- I have
looked into pci_map_single to map a buffer -- but I am failing to see
how ib_get_dma_mr fits in with this....
The sdp example (in
gen2/trunk/src/linux-kernel/infiniband/ulp/sdp) makes a call to
ib_get_dma_mr (sdp_conn.c:1812) and then calls to dma_map_single
(sdp_recv.c:85 and sdp_send.c:129) although I am failing to see the
connection.
Also, this might not be a question I should ask here, but why not?
What is the difference between pci_map_single and dma_map_single ? Are
they interchangable?
Thanks.
