Driver rxe does not support kernel ABI #74

Closed fwmiller closed 5 years ago

fwmiller commented 5 years ago

Getting a small error when I try to do an rping test. I'm building rxe into kernel 4.16 and rdma-core using yocto on an Arria10 socfpga containing a dual core A53 ARM processor. I get the kernel modules and userland loaded:

root@arria10:~# lsmod | grep rxe rdma_rxe 102400 0 ib_core 192512 6 rdma_rxe,ib_cm,rdma_cm,ib_uverbs,iw_cm,rdma_ucm

I can configure the rxe0 device but rxe_cfg is giving a strange error:

root@arria10:~# rxe_cfg libibverbs: Warning: Driver rxe does not support the kernel ABI of 1 (supports 2 to 2) for device /sys/class/infiniband/rxe0 IB device 'rxe0' wasn't found Name Link Driver Speed NMTU IPv4_addr RDEV RMTU eth0 yes st_gmac 1500 10.0.1.24 rxe0 (?)

Any hints on what this means, i.e. the kernel ABI error would be appreciated!

Thanks, FM

BTW,I've done an rxe_cfg add of eth0 (which works fine and can ping google for example) but ibv_devices gives this output:

root@arria10:~# ibv_devices libibverbs: Warning: Driver rxe does not support the kernel ABI of 1 (supports 2 to 2) for device /sys/class/infiniband/rxe0 device node GUID

root@arria10:~#

i.e. no device or GUID are listed...

Thanks, FM
