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.

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. ________________________________ From: [EMAIL PROTECTED] on behalf of Smith, Stan Sent: Wed 10/10/2007 17:51 To: [email protected] Subject: [ofw] IB Atomic COMPARE_AND_SWAP returns IB_AE_WQ_REQ_ERR? 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. _______________________________________________ ofw mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ofw
