According to Intel GFX PRM on 01.org, the MI_DISPLAY_FLIP command can either request display plane flip synchronously or asynchronously. In synchronous flip, flip will be hold until next vsync, which is not implemented yet in GVT. In asynchronous flip, flip will happen immediately, which is current implementation. The patch enables the sync flip on handling MI_DISPLAY_FLIP, and increment flip count correctly by only increment on primary plane. v2: Use bit operation definition for flip mode.

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 Restructured Text 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.
