* Simplify Nvidia registration.wip-kernsthreads-nvGlenn Elliott2011-03-31
| | | | | | Cleaned up the interface to register nvidia devices. Removed reliance on use of pid since we always assumed pid was the calling thread (AKA 'current').
* Merge branch 'wip-k-fmlp' into wip-kernsthreads-nvGlenn Elliott2011-03-31

| * Add interface for K-FMLP.Glenn Elliott2011-03-31
| | | | | | | | Added hooks to support K-FMLP.
* | Added function prototype to litmus.h.Glenn Elliott2011-03-08
|/ | | | Make nv-registration visible to user code.
* 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.
* refactor: remove all architecture-dependent code from include/Bjoern B. Brandenburg2010-11-09
| | | | Move the architecture-dependent code to the arch/ subtree.
* refactor: use architecture-specific includes for cycles.hBjoern B. Brandenburg2010-11-09

* 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.
* 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.

| | | | | 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.
