AMD and Hygon CPUs have a CPUID bit for RAPL. Drop the fam17h suffix as it is stale already. Make use of this instead of a model check to work more nicely in virtual environments where RAPL typically isn't available. [ bp: drop the ../cpu/powerflags.c hunk which is superfluous as the "rapl" bit name appears already in flags. ] Signed-off-by: Andrew Cooper <andrew.cooper3@citrix.com> Signed-off-by: Borislav Petkov <bp@suse.de> Link: https://lkml.kernel.org/r/20210514135920.16093-1-andrew.cooper3@citrix.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.
