We really want to have fastboot enabled by default to avoid an ugly modeset during boot. Currently we are enabling fastboot by default on gen9+ (Skylake and newer). The intention is to enable it on older generations after it has seen more testing on gen9+. VLV and CHV devices are still being sold in stores today, as such it is desirable to also enable fastboot by default on these now. I've extensively tested fastboot=1 support on over 50 different Bay- and Cherry-Trail devices. Testing DSI and eDP panels as well as HDMI output (and even DP over Type-C on one device). All 50 devices work fine with fastboot=1. On 2 devices their DSI panel turns black as soon as the i915 driver loads when fastboot=0, so having fastboot enabled is required for these 2 to work properly (for lack of a better fix).

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.
