One simple and quick check

Do you specify ATOMIC_ACCESS when you open the QP ? 

 

yes - IB_AC_ATOMIC | IB_AC_RDMA_READ | IB_AC_RDMA_WRITE |
IB_AC_LOCAL_WRITE are all set on the QP.

what HW do you use?  InfiniHost MT25208 - mthca.sys from openib-windows
svn.849, x64 on WinSvr 2003 (SP2); local process with RC connection to
another local process; should work?

 

if its mellanox HW there should be vendor syndrome in the EQE entry , it
should be in the same offset of the vendor syndrome of the CQE.

You can change the driver to report it - this will might help us to
identify the problem  

 

Thanks for the tip, will instrument the driver to display information
and get back to you.

 

stan.

Hello all,
  I'm working on DAT v2 extensions which include an Atomic
Compare-n-swap operation.
The comp-n-swap operation generates an async QP error callback with
IB_AE_WR_REQ_ERR?
The IB_AE_WR_REQ_ERR code is defined as 'an Opcode violation @ the
responder'?

Any clues as to what might generate an IB_AE_WR_REQ_ERR or what an
opcode violation @ responder implies?

Anyone have an IBAL based compare-n-swap test program they would like to
share?

Thanks,

Stan.
