* Add rtspin_edffm launcher functionAndrea Bastoni2010-09-22
| | | | | | | | | | | | | | | | | | It reads the parameter for a task from a text file. The format is: - <task-id, wcet, period, phase, firstcpu, number of slices> (for task parameters). - <task-id, cpu, deadline, wcet, phase> (for slices). Example: 15 2.96343109764 10 0 3 7 15 3 1.428571 1.175260 0.000000 15 7 2.857143 0.700065 1.428571 15 2 4.285714 0.504732 2.857143 15 0 5.714286 0.279637 4.285714 15 1 7.142857 0.185294 5.714286 15 4 8.571429 0.065379 7.142857 15 6 10.000000 0.053062 8.571429

* Support budget enforcement policies. Allows tasks to specifyGlenn Elliott2010-05-20
| | | | | | | | how their execution budgets should be enforced: NO_ENFORCEMENT, QUANTUM_ENFORCEMENT, and PRECISE_ENFORCEMENT (unsupported). NOTE: Users of NO_ENFORCEMENT must call sleep_next_period() at the end of every job to signal to the kernel that its job is complete.

* Improve build system.Bjoern B. Brandenburg2010-03-17
| | | | | | | | | | | | | | | Restructure SConstruct to reduce the likelihood of errors and to provide additional feedback. Features: - Better help. You can now run 'scons -h' to get a listing of all build options. - Local configuration. Build variables are picked up in a local .config file, if present. - Added --dump-config option to display the build configuration. - Use scons substitution system to avoid having to do parameter substitutions manually. - Some assorted fixes.

| * Build fix: support building on i686 systemsBjoern B. Brandenburg2010-03-10
| | | | | | | | | | | | | | 32bit Intel systems don't actually report 'x86' as their architecture, rather, they are i?86 systems. Provide a lookup table to map these codes to the 'x86' name that is used in the SConstruct file.
| * Fix error message.Bjoern B. Brandenburg2010-03-10
| | | | | | | | This is liblitmus, not ft_tools.
* | Add -v (verbose) switch to rtspin.Bjoern B. Brandenburg2010-03-10
|/ | | | | Can be used to dump the delay loop that rtspin is using.

* Remove prototype for non-existing system call.Bjoern B. Brandenburg2010-02-26
| | | | | This syscall hasn't been around since Fall 2007... The RTCSA'08 paper details how we are doing it now.

* | 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.

| * Build: allow cross-compiling to i386 on x86_64 machinesMitchell Jareo2009-02-22
| | | | | | | | | | | | | | | | This patch adds a hook to SConstruct to evaluate the ARCH env variable. Currently, only x86-64 => i386 is supported. Cross compiling works like this: $ ARCH=i386 scons
