A significant difference with adaptive PEBS is that arch-PEBS record supports fragments which means an arch-PEBS record could be split into several independent fragments which have its own arch-PEBS header in each fragment. This patch defines architectural PEBS record layout structures and add helpers to process arch-PEBS records or fragments. Only legacy PEBS groups like basic, GPR, XMM and LBR groups are supported in this patch, the new added YMM/ZMM/OPMASK vector registers capturing would be supported in the future.

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.
