mstconfig Commands
mstconfig Backup Command
The backup command is used to save the current non-volatile configurations (TLV) in the device into
a file in raw TLV syntax so it can be restored anytime using the set_raw command.
mstconfig backup command allows backing up the all of the configurations which are related only to
the PCI Physical Function associated with the given MST device. To back up all of the device
configurations, perform the operation from every PCI Physical Function the device exposes.
Restoring the configurations must be made from the matching PCI Physical Function.

Generating an XML Template for the Configurations
Users can generate an XML file that contains a template for the configurations. The
template describes the configurations and their parameters. No values are included in the template.
To generate such a template, run the gen_tlvs_file command. This command will generate a
file containing a list of all supported configurations by mstconfig, with a zero appearing in the end
of each configuration. To choose a configuration, change the 0 to 1, then save the file and run
the gen_xml_template command. An XML file containing the required configurations will
be generated.
Example:
# mstconfig gen_tlvs_file /tmp/confs.txt
Saving output...
Done!
# cat /tmp/confs.txt
