Since old kernel versions wouldn't expose the IN_FORMATS_ASYNC blob, userspace can't really use the absence of the blob to determine that async flips aren't supported. Thus it seems better to always expose the blob on all planes, whether they support async flips or not. The blob will simply not indicate any format+modifier combinations as supported on planes that aren't async flip capable. Currently we expose the blob for all skl+ universal planes (even though we implement async flips only for the first plane on each pipe), and i9xx primary planes (for ilk+ we have async flips support, for pre-ilk we do not). Complete the full set by also expsosing the blob on pre-skl sprite planes, and cursors.

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.
