mellanox / rdmamap

RDMA library for mapping associate netdevice and character devices

rdmamap

This is golang package that provides map of rdma device with its character and network devices.

It uses sysfs and netlink interfaces provided by kernel to perform this mapping.

Local build and test

You can use go get command:

go get github.com/Mellanox/rdmamap

Example:

package main

import (
    "fmt"
    "github.com/Mellanox/rdmamap"
)

func main() {
	rdmaDevices := rdmamap.GetRdmaDeviceList()
	fmt.Println("Devices: ", rdmaDevices)
  
	for _, dev := range rdmaDevices {
		charDevices := rdmamap.GetRdmaCharDevices(dev)
		fmt.Printf("Rdma device: = %s", dev)
		fmt.Println(" Char devices: = ", charDevices)
	}
}

rdmamap's Issues

Get status of a port

Hi,
Would it be possible to report status of a port? This information is available in /sys/class/infiniband/<dev>/ports/<port>/state.

Thanks!

Exporting the getPorts function in rdma_map.go

Hi,

Is there a specific reason why getPorts is not exported in rdma_map? It would be rather useful to have it exported there so ports can be iterated over when looking at statistics in a separate program.

Thanks,

Will.

module name

can you change in go.mod file Mellanox => mellanox ?
