modprobe: FATAL: Module rdma_rxe not found ;rxe modules not loaded #9

Closed Peng-git-hub closed 7 years ago

Peng-git-hub commented 7 years ago

When i load rdma_rxe kernel module using the command of sudo rxe_cfg start, it was failed saying modprobe: FATAL: Module rdma_rxe not found. rxe modules not loaded

And no file or directory matches the "/sys/module/rdma_rxe/parameters". This problem has been bothering me for a long time，looking for your help.

You probably have an older kernel Are you on upstream kernel?

@manishrajmohanty looks like your kernel is not built with SoftRoce support :(
