Support for Kernel 5.10+ ?

Hi, as a lot of changes on the infiniband / rdma stuff were happening in 5.10 kernel the OFED 5.4-1.0.3.0 is incompatible with it, after installation I’m getting lots of errors in the foramt:

Jul 6 13:34:36 at-host-46 kernel: ib_uverbs: Unknown symbol ib_unregister_client (err -22)

Jul 6 13:34:36 at-host-46 kernel: ib_uverbs: disagrees about version of symbol ib_query_srq

Jul 6 13:34:36 at-host-46 kernel: ib_uverbs: Unknown symbol ib_query_srq (err -22)

Jul 6 13:34:36 at-host-46 kernel: ib_uverbs: Unknown symbol ib_destroy_rwq_ind_table (err -2)

Is there an eta for a newer version with support for kernel 5.10+ ?

Where can I find the maximum supported kernel version for a specific OFED release?

Hello Thomas,

Thank you for posting your inquiry on the NVIDIA Networking Community.

Based on the information provided, the errors you are facing appear when the kernel is update and the MLNX_OFED was already installed based on the previous kernel.

To resolve this issue, we recommend to uninstall the current MLNX_OFED installation through the syntax → # ofed_uninstall.sh

and then reinstall MLNX_OFED with the following syntax → # ./mlnxofedinstall --add-kernel-support -vvv -y

Be aware that MLNX_OFED 5.4 GA does not support kernels > 5.10+. Currently there is no information available when MLNX_OFED will support kernels > 5.10+

Thank you and regards,
