Infiniband Support #1228

Open jiayu-hotstar-zz opened 2 years ago

jiayu-hotstar-zz commented 2 years ago

Hi, I'm using Bitfusion 4.0 server which resides on Photon OS 4.0. It has some infiniband related kernel modules like ib_core, ib_uverbs but there is no ib_ipoib kernel module. Only with this module can bitfusion server get connected with client. In fact, all modules under drivers/infiniband/ulp are missing. How could I bring in these modules?

Looks like I cannot install kernel source with yum/tdnf on photonOS, how could I build kernel module?

good question. Do you use a Mellanox setup? In the Mellanox forum are some hints about „why I can‘t load MLX5 in kernel 4.19“. It might be helpful for Ph4 flavors as well.
