Hi Amir, I put in off status the ZCopy with command: # echo 0 > /sys/module/ib_sdp/parameters/sdp_zcopy_thresh I comment out some lines in file sdp_main.c, but now the programs don't compile with a lot of errors. I list out the lines that I have commented out: file sdp_main.c line 2625: struct ib_fmr_pool_param fmr_param lines from 2645 to 2661 lines 2665 2666 lines from 2739 to 2745 All these lines contain a word "fmr". I don't find word "fmr" in file sdp_cma.c; sdp_main.c calls objects of sdp_cma.c SDP doesn't work. The output message of dmesg command is: sdp_init_qp:105 sdp_sock SDP not available on device nes0. I would like identify the problem: if we are almost sure that Fast Memory Region FMR is responsible for that, the bug 2028 solution in July will remove the error and I hope that SDP will work fine. On the other side, if FMR is not involved, there is an unknown situation and I am not happy. Could you evaluate the written error? Could you give me your opinion? Amir and Steve, thank you very much for help.
