Makefile.perf uses "CONFIG_*" checks in the code. Example the config for libtraceevent is used to set PYTHON_EXT_SRCS ifeq ($(CONFIG_LIBTRACEEVENT),y) PYTHON_EXT_SRCS := $(shell grep -v ^\# util/python-ext-sources) else PYTHON_EXT_SRCS := $(shell grep -v '^\#\|util/trace-event.c' util/python-ext-sources) endif But this is not picking the value for CONFIG_LIBTRACEEVENT that is set using the settings in Makefile.config. Include the file ".config-detected" so that make will use the system detected configuration in the CONFIG checks. This will fix isues that could arise when other "CONFIG_*" checks are added to Makefile.perf in future as well.

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.
