Linux kernel source tree
a58b9e3d6e
Currently our crtc_state->vrr.{vmin.vmax,flipline} are mangled on
TGL to account for the SCL delay (the hardware requires this mangling
or the actual vtotals will become incorrect). Unfortunately this
means that one can't simply use these values directly in many places,
and instead we always have to go through functions that undo the
damage first. This is all rather fragile.
Simplify our lives a bit by hiding this mangling deeper inside
the low level VRR code, leaving the number stored in the crtc
state actually something that humans can use.
This does introduce a dependdency as intel_vrr_get_config()
will now need to know the SCL value, which is read out in
intel_get_transcoder_timings(). I suppose we could simply
duplicate the SCL readout in both places should this become
a real hinderance. For now just leave a note around the
intel_get_transcoder_timings() call to remind us.

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.
