Hello all, Starting with the v6.3-rcX kernel releases I noticed that my InfiniBand devices were no longer present under /sys/class/infiniband, causing some of my automated testing to fail. It took me a while to find the time to bisect the issue, but I eventually identified the problematic commit: commit fe998a3c77b9f989a30a2a01fb00d3729a6d53a4 Author: Shay Drory <shayd@xxxxxxxxxx> Date: Wed Jun 29 11:38:21 2022 +0300 net/mlx5: Enable management PF initialization Enable initialization of DPU Management PF, which is a new loopback PF designed for communication with BMC. For now Management PF doesn't support nor require most upper layer protocols so avoid them. Signed-off-by: Shay Drory <shayd@xxxxxxxxxx> Reviewed-by: Eran Ben Elisha <eranbe@xxxxxxxxxx> Reviewed-by: Moshe Shemesh <moshe@xxxxxxxxxx> Signed-off-by: Saeed Mahameed <saeedm@xxxxxxxxxx> I'm not a mlx5 driver expert so I can't really offer much in the way of a fix, but as a quick test I did remove the 'mlx5_core_is_management_pf(...)' calls in mlx5/core/dev.c and everything seemed to work okay on my test system (or rather the tests ran without problem). If you need any additional information, or would like me to test a patch, please let me know. -- paul-moore.com
