The area of memory that contains the metrics table may contain garbage when the cycle starts. This normally doesn't matter because the cycle itself will populate it with valid data, however commit9f5595d5f0("platform/x86/amd: pmc: Require at least 2.5 seconds between HW sleep cycles") started to use it during the check() phase. Depending upon what garbage is in the table it's possible that the system will wait 2.5 seconds for even the first cycle, which will be visible to a user. To prevent this from happening explicitly clear the table when logging is started.

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.
