Add a pseudo event called branch-brs to help use the FAM Fam19h Branch Sampling feature (BRS). BRS samples taken branches, so it is best used when sampling on a retired taken branch event (0xc4) which is what BRS captures. Instead of trying to remember the event code or actual event name, users can simply do: $ perf record -b -e cpu/branch-brs/ -c 1000037 .....

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.
