Summary | 0016726: mlx4_core driver does not support ConnectX-2 cards | ||||
Description | The above kernel module supports Mellanox ConnectX-2 cards by default as long as it is compiled with switch CONFIG_MLX4_CORE_GEN2. As per https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/ethernet/mellanox/mlx4/Kconfig?h=v5.4-rc7 this is the default setting for recent kernels. CentOS 8 for some reason disabled this setting and ConnectX-2 cards do not work any longer. | ||||
Tags | InfiniBand | ||||
Additional info. Support for these cards is missing in the plus kernel too. # grep MLX4_CORE config-4.18.0-80.11.2.el8_0.centos.plus.x86_64 CONFIG_MLX4_CORE=m # CONFIG_MLX4_CORE_GEN2 is not set |
|
Will make the requested change in the next release of the plus kernel. However any change in the distro kernel must come from upstream (RHEL) . | |
