The QAT driver includes infrastructure to report power management (PM) information via debugfs. Extend this support to QAT GEN6 devices by exposing PM debug data through the `pm_status` file. This implementation reports the current PM state, power management hardware control and status registers (CSR), and per-domain power status specific to the QAT GEN6 architecture. The debug functionality is implemented in adf_gen6_pm_dbgfs.c and initialized as part of the enable_pm() function.

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.
