4.13.6 Burning Firmware with SR-IOV

The following procedure explains how to create a binary image with SR-IOV enabled that has 63

VFs. However, the number of VFs varies according to the working mode requirements.

 To burn the firmware:

Step 1. Verify you have MFT installed in your machine.

Step 2. Enter the firmware directory, according to the HCA type (e.g. ConnectX®-3).

The path is: /mlnx_ofed/firmware/<device>/<FW version>

Step 3. Find the ini file that contains the HCA's PSID. Run:

If such ini file cannot be found in the firmware directory, you may want to dump the configura-

tion file using mstflint. Run:

Step 4. Edit the ini file that you found in the previous step, and add the following lines to the [HCA]

section in order to support 63 VFs.

Step 5. Create a binary image using the modified ini file. Run:

The file <file name>.bin is a firmware binary file with SR-IOV enabled that has 63 VFs. It can

be spread across all machines and can be burnt using mstflint, which is part of the bundle, using

the following command:

1. Some servers might have issues accepting 63 Virtual Functions or more. In such case, please set the

number of "total_vfs" to any required value.

# mstflint -dev <PCI device> -image <file name>.bin b

After burning the firmware, the machine must be rebooted. If the driver is only

restarted, the machine may hang and a reboot using power OFF/ON might be required.
