BPF filtering tests can sometime fail. Running the test in verbose mode shows the following: $ sudo perf test 42 42: BPF filter : 42.1: Basic BPF filtering : FAILED! 42.2: BPF pinning : Skip 42.3: BPF prologue generation : Skip $ perf --version perf version 4.18.0-425.3.1.el8.ppc64le $ sudo perf test -v 42 42: BPF filter : 42.1: Basic BPF filtering : --- start --- test child forked, pid 711060 ... bpf: config 'func=do_epoll_wait' is ok Looking at the vmlinux_path (8 entries long) Using /usr/lib/debug/lib/modules/4.18.0-425.3.1.el8.ppc64le/vmlinux for symbols Open Debuginfo file: /usr/lib/debug/.build-id/81/56f5a07f92ccb62c5600ba0e4aacfb5f3a7534.debug Try to find probe point from debuginfo.

The statement above about the result being incorrect looks weird, and it is due to that particular perf build missing commit |

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.
