Vinay Belgaumkar 55f9720dbf drm/i915/guc/slpc: Provide sysfs for efficient freq
SLPC enables use of efficient freq at init by default. It is
possible for GuC to request frequencies that are higher than
the 'software' max if user has set it lower than the efficient
level.

Scenarios/tests that require strict fixing of freq below the efficient
level will need to disable it through this interface.

v2: Keep just one interface to toggle sysfs. With this, user will
be completely responsible for toggling efficient frequency if need
be. There will be no implicit disabling when user sets min < RP1 (Ashutosh)

v3: Remove unused label, review comments (Ashutosh)

v4: Toggle efficient freq usage in SLPC selftest and checkpatch fixes

v5: Review comments (Andi) and add a separate patch for selftest updates

Fixes: 95ccf312a1 ("drm/i915/guc/slpc: Allow SLPC to use efficient frequency")

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 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.
