VMWARE correctly enumerates lack of APERF and MPERF in CPUID, but turbostat didn't consult that before attempting to access them. Since VMWARE allows access, but always returns 0, turbostat got confusd into an infinite reset loop. Head this off by listening to CPUID.6.APERF_MPERF (and rename the existing variable to make this more clear) Reported-by: David Arcari <darcari@redhat.com> Tested-by: David Arcari <darcari@redhat.com> Signed-off-by: Len Brown <len.brown@intel.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 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.
