Linux kernel source tree

The system resume display mode restoration should happen with an output configuration matching that of the suspend time saved mode. Since the restored mode configuration is subject to the bpp fallback logic, starting out with an unlimited bpp and reducing the bpp as required by any (MST) link BW limit, the resulting bpp will match the one during suspend only if the BW limit checks during suspend and resume are applied in an identical way. The latter is not guaranteed at the moment, since the pre-suspend MST topology may not be in place during resume (for instance if the MST sink was disconnected while being suspended), which makes the MST link BW check accept the unlimited bpp mode configuration unconditionally without ensuring that the required BW fits into the available MST link BW. To fix the above, initialize the bpp fallback logic with the max link bpp / force-FEC limits left behind by the suspend time mode save.

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.
