Add --metric-no-group that causes all events within metrics to not be grouped. This can allow the event to get more time when multiplexed, but may also lower accuracy. Add --metric-no-merge option. By default events in different metrics may be shared if the group of events for one metric is the same or larger than that of the second. Sharing may increase or lower accuracy and so is now configurable.

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.
