During the bring-up of new platforms, or to take care of specific hardware reworks, it's useful to add a kernel parameter to override the default DMI-based quirks. For example, adding the following line in a .conf file in /etc/modprobe.d/ will change the default quirk and log the changes if dynamic debug is enabled. options snd_soc_sof_sdw quirk=0x802 [ 735.025785] sof_sdw sof_sdw: Overriding quirk 0x10 => 0x802 [ 735.025787] sof_sdw sof_sdw: quirk realtek,jack-detect-source 2 [ 735.025790] sof_sdw sof_sdw: quirk SOF_RT715_DAI_ID_FIX enabled Tested on ICL RVP with add-on board instead of default codec.

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.
