[Why] It's non trivial to configure or specify an ABM reduction level for userspace outside of X. There is also no method to specify the default ABM value at boot time. A parameter should be added to configure this. [How] Expose a module parameter that can specify the default ABM level to use for eDP connectors on DC enabled hardware that loads the DMCU firmware. The default is still disabled (0), but levels can range from 1-4. Levels control how much the backlight can be reduced, with being the least amount of reduction and four being the most reduction.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
