* refactor: remove all architecture-dependent code from include/Bjoern B. Brandenburg2010-11-09
| | | | Move the architecture-dependent code to the arch/ subtree.

* avoid including header files directlyBjoern B. Brandenburg2010-11-09
| | | | | | | | | | | | | | | The kernel warns against including header files directly. For good reason: our previous approach (just -I$KERNEL/include) caused all kinds of files to be included that should have come from /usr/include instead. This patch rewrites the Makfile so that the (few) needed headers are copied into the liblitmus src tree before compiling the library. This avoids having to specify the kernel include directories with -I, and also makes it easier to link against liblitmus (external applications do not need to know where the kernel is). Finally, this allows us to enable -Werror.
* 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.

* Don't show output from `which dialog` in setschedMac Mollison2010-11-09
| | | | | | | | Prevents `which dialog` from outputting (ugly) information to stderr in the case that dialog is not installed. Changes error message to make it more clear that dialog is strictly optional.
* Location change for the /proc loaded plugins file.Christopher Kenna2010-10-22

* rtspin: add -e option to enable PRECISE_ENFORCEMENT2010.2Bjoern B. Brandenburg2010-10-19
| | | | Useful to test how the kernel handles PRECISE_ENFORCEMENT.
* zero out rt_task parameters before setting themBjoern B. Brandenburg2010-09-22
| | | | | | | This avoids passing random stack contents to the kernel if the structure gained some fields due to plugin development. (Also, fix up some white space issues while we are at it.)
* 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.

* | 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.
