When invoked by the user, this task creates a file containing the
differences between the original config as produced by
do_kernel_configme
task and the changes made by the user with other methods
(i.e. using
(do_kernel_menuconfig
).
Once the file of differences is created, it can be used to create
a config fragment that only contains the differences.
You can invoke this task from the command line as follows:
$ bitbake linux-yocto -c diffconfig
For more information, see the "Generating Configuration Files" section in the Yocto Project Linux Kernel Development Manual.
