Badal Nilawar bf694844da drm/xe/d3cold: Set power state to D3Cold during s2idle/s3 
[ Upstream commit f945dd89fa ]

According to pci core guidelines, pci_save_config is recommended when the
driver explicitly needs to set the pci power state. As of now xe kmd is
only doing pci_save_config while entering to s2idle/s3 state, which makes
pci core think that device driver has already applied required pci power
state. This leads to GPU remain in D0 state. To fix the issue setting
the pci power state to D3Cold.

README 

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.
