* Add unit-test for CPU mapping parsingMahircan Gul2016-07-18
| | | | | | | | - Decompose read_mapping into two functions: *read_mapping* which reads CPU mapping data as string from file, and *set_mapping* that actually sets the cpu_set_t according to the mapping - Add unit test for setting cpu_set_t to various CPU indexes
* Add test case for get_rt_task_param()Bjoern Brandenburg2015-12-18
|
* Implement get_job_no() via control pageBjoern Brandenburg2015-12-16
|
* Tests: stress PCP, DPCP, DFLP, and SRP by intentionally migrating awayBjoern Brandenburg2015-07-27
| | | | Triggers a BUG_ON() in the old kernel.
* Test suite: add -v (verbose) option to runtestsBjoern Brandenburg2015-07-27
| | | | | Logging PIDs makes finding the right message in kernel debug traces easier...
* Testcases: create PCP and DFLP locks with invalid CPU parametersBjoern Brandenburg2015-07-27
|
* Testcase: create DPCP lock with invalid CPU parameterBjoern Brandenburg2015-07-27
|
* Add test cases for enforcement of periods of periodic tasksBjoern Brandenburg2014-06-12
|
* Remove over-specification of task parameters from two testsBjoern Brandenburg2014-06-03
| | | | Don't override the defaults unless required.
* FIX: Add S_IRUSR to open() for DFLP.Glenn Elliott2014-05-19
| | | | | This patch adds S_IRUSR as the third parameter to open() in the DFLP locking unit test.
* Remove invalid CPU parameter testBjoern Brandenburg2014-04-01
| | | | | | | | The LITMUS^RT kernel was changed to no longer test for "invalid" CPU paramters to allow reuse of the CPU parameter to denote virtual CPUs, reservations, etc. This patch removes the corresponding test.
* Add add convenience wrapper and tests for the DFLPBjoern Brandenburg2014-04-01
|
* Add test cases for exiting/mode-changing lock holdersBjoern Brandenburg2014-03-19
| | | | | This crashes old versions of the kernel. Kernel patches fixing the various panics have been merged into the kernel staging tree.
* liblitmus/tests: Add PCP-DPCP interleaving testRoy Spliet2014-03-19
|
* Add a test for admission of tasks that are currently runningBjoern Brandenburg2013-06-08
| | | | | Complements the prior test for suspended tasks. All plugins currently pass this test.
* Add testcase for admission of suspended tasksBjoern Brandenburg2013-06-08
| | | | | | The kernel needs to be able to deal with tasks that do not make themselves a real-time task, but get configured by some other task instead.
* Change convenience API routines.Glenn Elliott2013-03-12
| | | | | | | | | | | | | The sproadic_*() macros have become unwieldy. This patch replaces those convenience macros for global, clustered, and partitioned scheduling. A part of this API change is the explicit use of nanosecond time-values. Prior APIs have used lt_t (litmus time), which had an implied time scale of nanoseconds. /bin apps and test suite also updated to use revised API. Modifications to the test suite are mostly centered around using nanoseconds instead of milliseconds.
* Auto-CPU-affinity from part./cluster assignment.Glenn Elliott2013-03-12
| | | | | | | | | | | This patch replaces be_migrate_to() with several be_migrate_*() APIs to automatically assign CPU affinity masks from a task's partition (or cluster) assignment. Routines are release-master-aware such that the release master (if one exists) will NOT be included in the task's affinity mask. (Note that release-master avoidance may be overridden by calling __be_migrate_thread_to_cluster().)
* Make github/staging complatible with -O2.Glenn Elliott2013-03-12
| | | | | Minor changes to test case code to enable compilation with 'gcc -O2' (gcc v4.7.2).
* uncachedev: uncache test tool.Glenn Elliott2013-03-12
| | | | | | | | | | | | | | | | | This adds the uncache test tool (bin/uncache.c). The tool can be used to test Litmus's char device driver for allocating uncacheable CPU memory. The tool runs various checks and gathers basic cache vs. main memory statistics. In the future, uncache could be extended to quantify the benefits of the L1, L2, and L3 caches, instead of treating them as a black box. Note: Uncache works best when compiled with '-O2'. While '-O2' has not been added to the Makefile, other code was updated (code in tests/ and rtspin), to compile with -O2. DEPENDS UPON LITMUS-RT PATCH 888d097deb6d1fdc0c89a4f9667fd81cf416cfc7.
* Add test cases that check whether nesting is prohibitedBjoern Brandenburg2013-02-15
| | | | | The kernel should deny attempts to nest resources in ways that are not supported.
* Add tests for PCP/SRP ceiling blockingBjoern Brandenburg2013-01-11
| | | | | Context: priority inheritance triggered a BUG_ON() in fp_common.c. While at it, add a similar test for the SRP.
* Add testcase for preemptions on wakeup under P-EDF and P-FPBjoern Brandenburg2012-08-14
| | | | | | Resuming higher-priority tasks should of course preempt lower-priority tasks. This test case infers if higher-priority tasks are unreasonably delayed.
* Reduce artifical delay in testBjoern Brandenburg2012-08-14
| | | | | The 2 second delay was quite annoying. Make it short enough to not be so obvious.
* Add tests for the DPCP and the MPCPBjoern Brandenburg2012-08-14
| | | | | Do the basic open/lock/unlock/close test sequence for the MPCP and the DPCP as well.
* test case: reject infeasible densities2012.2archive/unc-master-3.0Bjoern Brandenburg2012-08-01
| | | | | Add a test that makes sure that the kernel does indeed not accept infeasible densities.
* Run test suite for currently active plugin by defaultBjoern Brandenburg2012-08-01
| | | | Try to infer current plugin if no plugin is specified.
* API Update: Support arbitrary deadlines.Glenn Elliott2012-08-01
| | | | | | | | Updated APIs to support arbitrary deadlines. Added macros for implicit deadlines. Note: Had to tweak Makefile to support gcc version >= 4.6 (moved -lrt to the end of the link command).
* Properly report tests that segfault.Bjoern Brandenburg2012-07-23
| | | | | Segmentation faults are clearly test failures; make sure to report them accordingly.
* New test: /dev/litmus/ctrl must be writableBjoern Brandenburg2012-07-23
| | | | | Under any plugin, the control page should be mappable and writable.
* Add test cases for P-FP prioritiesBjoern Brandenburg2012-06-26
| | | | | Make sure out-of-range priorities are always rejected.
* P-FP: make PCP available to user spaceSven Dziadek2012-05-31
| | | | | | PCP was only used for DPCP before tests: add some basic tests for PCP under P-FP
* P-FP: port P-FP plugin used in B. Brandenburg'sSven Dziadek2012-05-31
| | | | | | | | | dissertation (branch bbb-diss) I took the unchanged code but removed references to OMLP which was and is not implemented tests: changed so that they work for P-FP
* tests: add valid budget_policy to rt_task parametersAndrea Bastoni2011-08-26
| | | | | | | Since set_rt_task_param() checks for wrong budget policies, make sure to specify a valid policy to avoid errors like the following. litmus: real-time task 3635 rejected because unsupported budget enforcement policy specified
* tests: allow 'LITMUS' as an alias of all non-Linux pluginsBjoern B. Brandenburg2011-02-03
| | | | This is useful for tests that apply to any plugin.
* add test cases for the FMLP and SRP under GSN- and PSN-EDFBjoern B. Brandenburg2011-02-03
|
* switch to generic locking system callsBjoern B. Brandenburg2011-02-03
| | | | | The new generic lock layer in LITMUS^RT does away with per-protocol system calls. Change accordingly.
* add test that checks that RT class is not inherited across forkBjoern B. Brandenburg2011-02-01
|
* refactor: switch back from SCons to makeBjoern B. Brandenburg2010-11-09
| | | | | | | | | | | | | | | We originally switched from make to scons because 1) our makefiles were not very good; 2) SCons promised to make maintaining the build system simpler. Unfortunately, SCons has become more and more difficult to deal with as we moved to supporting several architecture and cross compilation, to the extend that we ended up re-creating make functionality in SCons. So let's switch back to make using a "clean" Makefile. Thanks a lot to Andrea Bastoni and Chris Kenna for feedback on previous iterations of these patches.

* add test case for set_rt_task_paramBjoern B. Brandenburg2010-02-25
| | | | Specifically, make sure invalid pointers are rejected.
* Introduce test framework for LITMUS^RT.Bjoern B. Brandenburg2010-02-20
This is the beginning of the LITMUS^RT testsuite. The main design goals are flexibility and ease of test writing. To create a new test, simply write a test case in any C file in the tests/ subdirectory. The buildsystem will find the test and hook it up with the testrunner. Have a look at tests/fdso.c and include/tests.h to get an idea for what tests look like. Tests can be executed with the 'runtests' tool. Each testcase is executed in a separate process in order to ensure that tests do not influence each other.
