For Perf to be able to decode when per-sink trace IDs are used, emit the sink that's being written to for each ETM. Perf currently errors out if it sees a newer packet version so instead of bumping it, add a new minor version field. This can be used to signify new versions that have backwards compatible fields. Considering this change is only for high core count machines, it doesn't make sense to make a breaking change for everyone.

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.
