/sys/class/graphics/fb0/device/drm/card0/ and /sys/class/drm/card0/ point to the same device node. But in some cases, one exists and the other one does not. Prefer to use /sys/class/drm/card0/, and fall back to /sys/class/graphics/fb0/device/drm/card0/. This recovers the "GFXMHz" and "GFXAMHz" columns on some platforms like a SPR server.

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.
