Older VBTs don't have all the stuff we've defined for the LVDS options block (40). In particular we're currently parsing the DPS panel type bits even though they may not exist, which could mean we end up flagging the machine as supporting static DRRS when the VBT declared no such thing. We don't actually have a clear idea which VBT versions have which bits so we rely on the block size instead. Here's a quick list from my VBT stash: mgm version 108 -> 4 bytes alv version 120 -> 4 bytes cst version 134 -> 14 bytes pnv version 144 -> 14 bytes cl version 142 -> 16 bytes ctg version 155 -> 24 bytes Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220615151445.8531-2-ville.syrjala@linux.intel.com Acked-by: Jani Nikula <jani.nikula@intel.com>
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.
