Miller, Eric Dumazet, Jakub Kicinski, Paolo 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. It uses vfio_pci_core to register to the VFIO subsystem and then mlx5 core is modular and most of the major mlx5 core driver features can be selected (compiled in/out) at build time via kernel Kconfig flags. ehrhardt@canonical. 36 2 2 Hi, I am trying to run krping code which I got from the below link on the Linux kernel 4. Example: 8. Set default ToS to 24 (DSCP 6) mapped to skprio 4: # cma_roce_tos -d mlx5_0 -t 24. Means NIC 1 port 0 goes to NIC 2 port 0, this is working fine Firmware Downloads . Procedure.

Windows 2012R2 may generate a Blue Screen crash: DRIVER_IRQ_NOT_LESS_OR_EQUAL when attempting to install Mellanox drivers for ConnectX-3 / Pro. With TX inlining, there are some checks that fail in the underlying verbs library (which is called from DPDK during QP Creation) if a large number of descriptors is used. Miller, Eric Dumazet, Jakub Kicinski, Paolo Since the same mlx5_core driver supports both Physical and Virtual Functions, once the Virtual Functions are created, the driver of the PF will attempt to initialize them so they will be available to the OS owning the PF. Once the rings and memory pools are all available in both the primary and secondary processes, the application simply dedicates two threads to sending and receiving messages respectively.
