Ankit Nautiyal b811a7635a drm/i915/vrr: Use SCL for computing guardband
For now guardband is equal to the vblank length so ideally it should be
computed as difference between the vmin vtotal and vactive. However
since we are having few lines as SCL, we need to account for this while
computing the guardband.

Since the vblank start is moved by SCL lines from the vactive, the delta
between the vmin vtotal and new vblank start was used to account for this.
Now that SCL is explicitly tracked using the `set_context_latency` member,
use it directly in the guardband calculation.

In the future, when the guardband is shortened or optimized, we may need
to factor in both the change in the vblank start and SCL lines. For now,
explicitly accounting for SCL is sufficient.

v2: Fix typo: replace adjusted_mode->vdisplay with
adjusted_mode->crtc_vdisplay. (Ville)

README

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 reStructuredText 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.
