For HP Inc. mobile workstation with hybrid graphics support, dGPU can directly output to external monitors; however, Nvidia and AMD's Linux drivers aren't able to support this feature. The OEM _OSI string "Linux-HPI-Hybrid-Graphics" is used by BIOS to implement dGPU direct output to external monitors. The form of the OEM _OSI strings is defined by each OEMs and is discussed in Documentation/acpi/osi.txt. Signed-off-by: Alex Hung <alex.hung@canonical.com> Signed-off-by: Rafael J.

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.
