Describe what a "BAD" link-status means for user-space and how it should
handle it. The logic described has been implemented in igt [1].
v2:
- Change wording to avoid "enabled" (Daniel)
- Add paragraph about multiple connectors sharing the same CRTC (Pekka)
- Add paragraph about performing an atomic commit on a connector without
updating the link-status property (Daniel)
v3:
- Fix description of what happens when link-status isn't reset to
"GOOD", and when link-status is reset without ALLOW_MODESET (Daniel,
Ville)
- Changing link-status to "BAD" is a no-op
- Clearly state that "BAD" means black screen (Manasi)

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.
