Saves PCIe bandwidth by compressing a few CQEs into a smaller amount of bytes on PCIe.

Small buffers are scattered to the completion queue entry and manipulated by the driver.

128 - completion queue entry size is 128 bytes.

64 - completion queue entry size is 64 bytes (default).

Used by applications that are single threaded and would like to save the overhead of taking spinlocks.

Otherwise - blue flame depends on the size of the message and inline indication in the packet.

Configures every work request that can use blue flame will use blue flame.

Causes the process to hang in a loop of completion with error, which is not flushed with error or retry exceeded occurs/.

The following are the libmlx5 environment variables:

If there is no compatibility between the firmware and the driver, the driver will not load and a message will be printed in the dmesg. Libmlx5 is the provider library that implements hardware specific user-space functionality. mlx5_ib Handles InfiniBand-specific functions and plugs into the InfiniBand mid layer.

Unlike mlx4_en/core, mlx5 drivers do not require the mlx5_en module as the Ethernet functionalities are built-in in the mlx5_core module. mlx5_core driver also implements the Ethernet interfaces for ConnectX®-4. initializing the device after reset) required by Connect-IB® and ConnectX®-4 adapter cards. Mlx5_core Acts as a library of common functions (e.g. The mlx5 driver is comprised of the following kernel modules: Connect-IB® operates as an InfiniBand adapter whereas and ConnectX®-4 operates as a VPI adapter (Infiniband and Ethernet). Mlx5 Driver mlx5 is the low-level driver implementation for the Connect-IB® and ConnectX®-4 adapters designed by Mellanox Technologies. mlx4_en A 10/40GigE driver under drivers/net/ethernet/mellanox/mlx4 that handles Ethernet specific functions and plugs into the netdev mid layer. mlx4_ib Handles InfiniBand-specific functions and plugs into the InfiniBand mid layer. Also controls resource allocation so that the InfiniBand and Ethernet functions can share the device without interfering with each other. Mlx4_core Handles low-level functions like device initialization and firmware commands processing. To accommodate the supported configurations, the driver is split into the following modules: The OFED driver supports InfiniBand and Ethernet NIC configurations. ConnectX®-3 adapters can operate as an InfiniBand adapter, or as an Ethernet NIC. Mlx4 is the low-level driver implementation for the ConnectX® family adapters designed by Mellanox Technologies. The following subsections briefly describe the various components of the Mellanox OFED stack. The application level also shows the versatility of markets that Mellanox OFED applies to. The figure below shows a diagram of the Mellanox OFED stack, and how upper layer protocols (ULPs) interface with the hardware and with the kernel and userspace.
