Linux kernel source tree

The oversampling rate used by the Jitter RNG allows the configuration of the heuristically implied entropy in one timing measurement. This entropy rate is (1 / OSR) bits of entropy per time stamp. Considering that the Jitter RNG now support APT/RCT health tests for different OSRs, allow this value to be configured at compile time to support systems with limited amount of entropy in their timer. The allowed range of OSR values complies with the APT/RCT cutoff health test values which range from 1 through 15. The default value of the OSR selection support is left at 1 which is the current default. Thus, the addition of the configuration support does not alter the default Jitter RNG behavior.

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.
