Linux kernel source tree
5adac4c9f3
If FBC is already active, we don't need to call FBC activate
routine again unless there are changes to the fences. So skip
this on all platforms that don't have fences. Any FBC register
updates done after enabling the dirty rect support in xe3 will
trigger nuke by FBC which is counter productive to the fbc
dirty rect feature.
The front buffer rendering sequence will call intel_fbc_flush()
and which will call intel_fbc_nuke() or intel_fbc_activate()
based on FBC status explicitly and won't get impacted by this
change.
v2: use HAS_FBC_DIRTY_RECT()
move this functionality within intel_fbc_activate()
v3: update to intel_fbc_activate logic (Ville)

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.
