Change IceLake Xeon C6 latency from 128 us to 170 us. The latency was measured with the "wult" tool and corresponds to the 99.99th percentile when measuring with the "nic" method. Note, the 128 us figure correspond to the median latency, but in intel_idle we use the "worst case" latency figure instead. C6 target residency was increased from 384 us to 600 us, which may result in less C6 residency in some workloads. This value was tested and compared to values 384, and 1000. Value 600 is a reasonable tradeoff between power and performance. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Acked-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Rafael J.

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.
