Currently we support only static linking with kernel's libtraceevent (tools/lib/traceevent). This patch adds libtraceevent package detection and support to link perf with it dynamically. The libtraceevent package status is displayed with: $ make VF=1 LIBTRACEEVENT_DYNAMIC=1 ... ... libtraceevent: [ on ] Default behavior remains the same (static linking). Committer testing: $ make LIBTRACEEVENT_DYNAMIC=1 VF=1 O=/tmp/build/perf -C tools/perf install-bin |& grep traceevent Makefile.config:1090: *** Error: No libtraceevent devel library found, please install libtraceevent-devel.

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.
