This adds a new counter tool to be able to test various watch events. A flexible watch array can be populated from command line, each field may be tuned with a dedicated command line sub-option in "--watch" string. Several watch events can be defined, each can have specific watch options, by using "--watch <watch 1 options> --watch <watch 2 options>". Watch options is a comma separated list. It also comes with a simple default watch (to monitor overflow/underflow events), used when no watch parameters are provided. It's equivalent to: counter_watch_events -w comp_count,scope_count,evt_ovf_udf The print_usage() routine proposes another example, from the command line, which generates a 2 elements watch array, to monitor: - overflow underflow events - capture events, on channel 3, that reads read captured data by specifying the component id (capture3_component_id being 7 here).

README
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.
