The Balancer and DCC strategies were left off on a fear that
these strategies would conflict with the i915's waitboost.
However, on MTL and Beyond these strategies are only active in
certain conditions where the system is TDP limited.
So, they don't conflict, but help the
waitboost by guaranteeing a bit more of GT frequency.
Without these strategies we were likely leaving some performance
behind on some scenarios.
With this change in place, the enabling/disabling of DCC and Balancer
will now be chosen by GuC, on a platform/GT basis.
v2: - Fix typos and be clear on GuC decision on platform basis (Vinay)
- Limit change to MTL and beyond, where GuC started to take
TDP limit into consideration.
v3: Fix compilation. Actually amend the changes...

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.
