kw-kernel-config-manager

SYNOPSIS

kw (k | kernel-config-manager) [(-s | –save) <name> [(-d | –description) <description>] [-f | –force]]
kw (k | kernel-config-manager) [-l | –list]
kw (k | kernel-config-manager) [–fetch [(-o | –output) <filename>] [-f | –force] [–optimize] [–remote [<remote>:<port>]]]:
kw (k | kernel-config-manager) [–get <name> [-f | –force]]
kw (k | kernel-config-manager) [(-r | –remove) <name> [-f | –force]]

DESCRIPTION

The kernel-config-manager command manages different versions of the project’s .config file. It provides the save, load, remove, and list operations of such files. By default, if the user does not provide any parameter, the kernel-config-manager will list all configs under kw’s management.

Note

This feature has interoperability with the kw env feature.

OPTIONS

–save <name> [-d <description>] [-f | –force]:

The save option creates a snapshot of the .config file in the current folder in kw’s management system under the specified <name>. Additionally, users can add a description by using the -d flag. Finally, if the user tries to add another config with a name that’s already being managed, kw will issue a warning; -f will suppress such a warning.

-l, –list:

Lists all the .config file versions available. This is also the default behavior when no option is specified.

–get <name> [-f | –force]:

Get a copy of the config file with the provided <name> in the current directory. As this operation overwrites the current .config file a warning is shown; -f will suppress such a warning and carry on any destructive operations.

-r <name> [-f | –force], –remove <name> [-f | –force]:

Remove config labeled with <name> from kw’s management system. As this operation removes a .config file from kw management a warning is shown; -f will suppress such a warning and carry on any destructive operations.

–fetch [(-o | –output) <filename>] [-f | –force] [–optimize] [–remote [<remote>:<port>]]:

Fetches a .config file from a target machine to your current directory. If another config is found in this directory, then kw will ask you whether you want to replace it or not; -f will suppress such a warning and carry on any destructive operations. --output allows you to specify the config file name, and --optimize will run make localmodconfig in order to generate a config that’s optimized for the target machine.

EXAMPLES

In the following examples, we assume your kworkflow.config file is already properly configured.

In case you want kw to save your current .config file, you can use:

cd <kernel-path>
kw k --save my_current_config

You can see the config’s file maintained by kw with:

kw k --list

If you want to fetch a config from a remote machine (available at localhost:2222) as root, you can run:

kw kernel-config-manager --fetch --remote root@localhost:2222
