* Add basic locking support to rtspinBjoern Brandenburg2013-02-04
| | | | | | This is useful for testing locking protocol implementations (not intended for benchmarking!), and also serves to document how to use the LITMUS^RT locking API.
* Include PID info in test failuresBjoern Brandenburg2013-01-14
| | | | Useful for correlating test failures to events in traces.
* 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.
* rt_launch: add support for -q <priority>Bjoern Brandenburg2013-01-11
| | | | This mirrors the option in rtspin.
* Make release_ts a bit more userfriendlyBjoern Brandenburg2013-01-11
| | | | | | | The -f option required manually *also* setting the -w option. This is no longer required. While at it, simplify the code by using the /proc interface.
* Pull fpmath.h for use in liblitmus.2012.3Glenn Elliott2012-12-21
| | | | | | Branch litmus-rt/prop/robust-tie-break added fpmath.h for fixed-point computations. Updated Makefile to pull this header from litmus-rt so it may also be used in liblitmus.
* Add control page offset checksstagingBjoern Brandenburg2012-12-06
| | | | | Make sure the kernel and userspace compilers have the same idea of the layout of the control page.
* 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.
* Implement lt_sleep() syscall wrapperBjoern Brandenburg2012-08-14
| | | | | Wrap nanosleep() to make sleeping for a given number of nanoseconds easier, using the LITMUS^RT time type lt_t.
* Implement get_nr_ts_release_waiters() /proc wrapperBjoern Brandenburg2012-08-14
| | | | | Add a wrapper for /proc/litmus/stats to make it easy to query the number of tasks already waiting for a task set release.
* 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.
* Add convenience wrappers for the DPCP and MPCPBjoern Brandenburg2012-08-14
| | | | For consistency reasons and to document the cpu parameter of the DPCP.
* git: ignore files generated by the build systemBjoern Brandenburg2012-08-14
| | | | Prevents accidental staging of auto-generated files.
* 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.
* Add a little explanation to the basic task prototypesBjoern Brandenburg2012-08-01
| | | | Also add the priority parameter, which was missing.
* 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.
* Make use of kernel-provided FP macrosBjoern Brandenburg2012-06-26
| | | | | | Use the kernel's notion of fixed priorities. Also, add some clarifying comments to the task setup wrappers.
* 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
* Change default path to remove *2010 tag.2012.1wip-2011.2-bbbBjoern B. Brandenburg2011-11-24
| | | | | This is not the 2010 version anymore, so let's use a version-agnostic path.
* Switch to new np-section protocol.Bjoern B. Brandenburg2011-11-24
| | | | Everything is in one 32-bit word now.
* update headersBjoern B. Brandenburg2011-11-24
| | | | we need uint64_t in litmus.h
* 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.
* Export wctime() and cputime() from rtspin to library clientsBjoern B. Brandenburg2011-02-03
| | | | | The timing functions are quite handy when building benchmark tasks. Avoid copy&paste reuse by making them available via the library.
* bugfix: switch operangs in delay computationBjoern B. Brandenburg2011-02-03
| | | | | We want the positive loop length, not the negative, to prevent jobs from overruning their budget.
* add test that checks that RT class is not inherited across forkBjoern B. Brandenburg2011-02-01
|
* Remove old delay loop configuration cruft from rtspinBjoern B. Brandenburg2011-01-30
| | | | | Using cputime() is much more accurate than the old delay loop auto-configuration. There is no good reason to keep it around.
* Modify RTSpin so that it can read execution time data from a CSV file.Christopher Kenna2011-01-30
| | | | | Still need to figure out what to do with the period is less than the exec_cost (or budget).
* fix header detection on ARM2011.1Bjoern B. Brandenburg2011-01-25
| | | | | | The ARM port uses <litmus... instead of "litmus..., so let's use egrep with a proper regular expression to reliably find the line that includes the Litmus system calls.
* don't require LITMUS^RT headers for 'make help'Bjoern B. Brandenburg2011-01-25
| | | | It should be possible to see the help when the configuration is broken.
* add installation instructions to liblitmus (and 'make help')Bjoern B. Brandenburg2010-11-24
| | | | | Some initial documentation to aid new users get started with compiling the library.
* add cscope target to MakefileBjoern B. Brandenburg2010-11-23
| | | | | cscope is very nice for exploring the library and finding related code. Let's support it by pre-building an index of all files.
* add TAGS and tags targets to MakefileBjoern B. Brandenburg2010-11-23
| | | | | It's nice to have a TAGS file around when exploring the library. Let's generate one for vim and emacs.
* Patch so Make will die if it detects non-LITMUS^RT kernel headers.Christopher Kenna2010-11-22
|
* Provide standard Makefile rules for clients of liblitmusBjoern B. Brandenburg2010-11-22
| | | | | | We avoid doing the same thing over and over in all repositories using liblitmus if we just pull in common rules & configurations from liblitmus. This gives us the ability to cross-compile for free.
* rtspin: transition back to non-real-time modeBjoern B. Brandenburg2010-11-22
| | | | | rtspin produces prettier schedules if it transitions to non-real-time mode before terminating.
* remove asm/atomic.hBjoern B. Brandenburg2010-11-09
| | | | | | | | | | | For historic resons, we carry old atomic operations support in liblitmus. This is no longer useful: 1) There is actually no client for these calls in liblitmus. 2) There is now a standard gcc API for this purpose. http://gcc.gnu.org/onlinedocs/gcc/Atomic-Builtins.html Thus, we can reduce our maintenance burden.
* generate error message if build config seems fishyBjoern B. Brandenburg2010-11-09
| | | | | Failing loudly is a lot better than just producing a cryptic error message about some dependency file.
* output header to STDERR in measure_syscallBjoern B. Brandenburg2010-11-09
| | | | This hopefully helps a bit to clarify the output.
* add emergency exit to rtspinBjoern B. Brandenburg2010-11-09
| | | | | | This should only trigger if the execution time tracking is broken (as it was on District10). With the emergency exit, we at least prevent the system from becoming unresponsive.
* don't require /bin/bashBjoern B. Brandenburg2010-11-09
| | | | | We don't have BASH on District10 at the moment, and the scripts work just fine with busybox's /bin/sh replacement (ash).
* add ARM architecture-dependent filesBjoern B. Brandenburg2010-11-09
| | | | | The atomic.h file is currently only a dummy, but it is sufficient to get basic real-time tasks to run.
