On Google Coral and Reef family Chromebooks with Intel Apollo Lake SoC, firmware clobbers the header of the L1 PM Substates capability and the previous capability when returning from D3cold to D0. Save those headers at enumeration-time and restore them at resume. [bhelgaas: The main benefit is to make the lspci output after resume correct. Apparently there's little or no effect on power consumption.] Link: https://lore.kernel.org/linux-pci/CAFJ_xbq0cxcH-cgpXLU4Mjk30+muWyWm1aUZGK7iG53yaLBaQg@mail.gmail.com/T/#u Link: https://lore.kernel.org/r/20230411160213.4453-1-ron.lee@intel.com Signed-off-by: Ron Lee <ron.lee@intel.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
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.
