Costa Shulyupin 3a4080e5e4 tools/rtla: Add unit tests for utils.c
Add unit tests for utility functions in src/utils.c using the Check
testing framework. The tests verify parse_cpu_set(), strtoi(), and
parse_prio() functions.

Unit tests are built conditionally when libcheck is available.
Run tests with 'make unit-test'.

The test framework uses the Check library which provides process
isolation for each test, preventing failures in one test from
affecting others.

RTLA: Real-Time Linux Analysis tools
The rtla meta-tool includes a set of commands that aims to analyze
the real-time properties of Linux. Instead of testing Linux as a black box,
rtla leverages kernel tracing capabilities to provide precise information
about the properties and root causes of unexpected results.
Installing RTLA
RTLA depends on the following libraries and tools:
- libtracefs
- libtraceevent
- libcpupower (optional, for --deepest-idle-state)
- libcheck (optional, for unit tests)
For BPF sample collection support, the following extra dependencies are
required:
- libbpf 1.0.0 or later
- bpftool with skeleton support
- clang with BPF CO-RE support
It also depends on python3-docutils to compile man pages.
For development, we suggest the following steps for compiling rtla:
$ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git
$ cd libtraceevent/
$ make
$ sudo make install
$ cd ..
$ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git
$ cd libtracefs/
$ make
$ sudo make install
$ cd ..
$ cd $libcpupower_src
$ make
$ sudo make install
$ cd $rtla_src
$ make
$ sudo make install
For further information, please refer to the rtla man page.
