Linux Test Project is a joint project started by SGI, OSDL and Bull developed and maintained by IBM, Cisco, Fujitsu, SUSE, Red Hat, Oracle and others. The project goal is to deliver tests to the open source community that validate the reliability, robustness, and stability of Linux.

More information at https://github.com/linux-test-project/ltp/blob/master/README.

The code for realtime test cases of ltp is available at: https://github.com/linux-test-project/ltp/tree/master/testcases/realtime

Following are the steps to quickly download ltp and build all the realtime related testcases:

$> git clone https://github.com/linux-test-project/ltp.git
$> cd ltp
$> make autotools
$> ./configure
$> cd testcases/realtime
$> ./configure
$> make

Detailed installation instructions can be found at https://github.com/linux-test-project/ltp/blob/master/INSTALL.

Following is the list of real-time testcases which are currently available in LTP:

• ./func/hrtimer-prio
• ./func/gtod_latency
• ./func/prio-wake
• ./func/thread_clock
• ./func/pi-tests
• ./func/prio-preempt
• ./func/periodic_cpu_load
• ./func/rt-migrate
• ./func/matrix_mult
• ./func/async_handler
• ./func/sched_football
• ./func/pthread_kill_latency
• ./func/measurement
• ./func/sched_latency
• ./func/pi_perf
• ./func/sched_jitter
• ./perf/latency

Description of all the test cases: https://github.com/linux-test-project/ltp/blob/master/testcases/realtime/00_Descriptions.txt

To run all the test cases, just traverse to ${SRC}/testcases/realtime and run the following command as root:

# please make sure to include the '-l' argument even though it is specified as optional 
# because there is a bug in ltp which throughs out a syntax error if the argument is not specified.
$> ./run.sh -t all -l 1

The user can also run functional, stress and performance test by providing func, stress and perf as argument to -t switch respectively.
