While doing some tests, I've found that rdma_client failed
on my QLogic/Intel QLE7340 / QLE7342 HCA:
# rdma_client
rdma_client: start
rdma_post_send 22
rdma_client: end -1
I had a deeper look on the examples and found that max_inline_data was returned
as 0,
thus IBV_SEND_INLINE is not available and memory must be registered to provide
a valid
lkey in WR.
[BTW, having registered the memory and still use IBV_SEND_INLINE was OK,
that should be an error, isn't it ?]
Please find some patches to
- document IBV_SEND_INLINE and memory registration,
- add a query function to check max_inline_data on QP created by cma,
- fix the examples to not use IBV_SEND_INLINE if max_inline_data is less than
expected.
Yann Droneaud (3):
man: rdma_post_*(): memory region is optional only with
IBV_SEND_INLINE.
adds rdma_query_qp() function.
examples: use IBV_SEND_INLINE if supported
