Looks like CCS + async flips has been a thing for a while now. Enable this for TGL+ render compression modifiers. Note that we can't update AUX_DIST during async flips we must check to make sure it remains unchanged. We also can't do clear color. Supposedly there was some attempt to make it work, but apparently the issues only got ironed out in MTL. For now we'll not worry about it and refuse async flips with clear color modifiers. Bspec claims that media compression doesn't support async flips. Based on a quick test it does seem to work to some degree, but perhaps it has issues as well. Let's trust the spec here and continue to refuse async flips + media compression.

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.
