7c373b3bd0The selective fetch code doesn't handle asycn flips correctly.
There is a nonsense check for async flips in
intel_psr2_sel_fetch_config_valid() but that only gets called
for modesets/fastsets and thus does nothing for async flips.
Currently intel_async_flip_check_hw() is very unhappy as the
selective fetch code pulls in planes that are not even async
flips capable.
Reject async flips when selective fetch is enabled, until
someone fixes this properly (ie. disable selective fetch while
async flips are being issued).

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.
