Introduce tracepoints to allow tracing the GLINK packets being exchanged with other subsystems. This is useful for debugging both interaction with remote processors and client driver issues, as well as tracking latency through the communication stack. Channel events are traced with both local and remote channel ids, as well as the textual representation when possible. The channel ids are useful when matching traces with traces from the firmware side logs, while the textual representation is necessary to identify channels when we're starting to trace an already running system.

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.
