* Merge branch 'prop/rt_task-init-final' into tempGlenn Elliott2013-03-13

| * 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.
| * Add init_rt_task_param().Glenn Elliott2013-03-12
| | | | | | | | | | Adds init_rt_task_param(). Facilitates setting up default real-time task attributes that cannot be set by memset(0).
| * Cluster-aware rtspin and rt_launch.Glenn Elliott2013-03-12
| | | | | | | | | | | | | | | | | | This patch adds cluster scheduling options to rtspin and rt_launch. The convenience routines in litmus.h were also updated to facilitate clustered scheduling. For partitioned scheduling, just set cluster_size = 1 (default size for rtspin and rt_launch).
| * 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().)

| * 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.

| * 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).
| * 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

| * | Updated sporadic_task() to take sig policy.Glenn Elliott2012-09-07
| |/ | | | | | | | | | | | | Also changed the LITMUS_TRY/LITMUS_CATCH/END_LITMUS_TRY macros to use if/else-if chains instead of switch statements. This is because SIGRTMAX is a variable in libc and not a compile-time constant (switches cant be used).

* 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.
* add sporadic_task_ns() helperBjoern B. Brandenburg2009-04-29
| | | | Allows for higher-precision setup of real-time tasks.

|
* many changesBjoern B. Brandenburg2008-02-03
| | | | | - use declarations from kernel - get rid of stuipd system call macros
* rip out old junkBjoern B. Brandenburg2008-02-03
|
* core: 2 bug fixesBjoern B. Brandenburg2008-01-28
| | | | | | | - Don't apply real-time parameters to thread group leader, apply them to the current thread. - Return 0 if no error occured in init_litmus() to make it consistent with the system calls of liblitmus.
* core: rip out task_active()Bjoern B. Brandenburg2008-01-24
|
* reorganize liblitmus to be more modularBjoern B. Brandenburg2008-01-23
|
* core: remove support for deprecated system callBjoern B. Brandenburg2008-01-22
|
* core: change real-time task creation to new transitioning methodBjoern B. Brandenburg2008-01-22
| | | The old clone based hack will be removed soon.

|
* ABI Change: adapt to new LITMUS syscall interface and incorporate FDSO callsBjoern B. Brandenburg2007-11-15
| | | This will break libso.

|
* add litmus_task_active() APIBjoern B. Brandenburg2007-09-19
| | | | | | Most RT tasks need to do some cleanup before they can terminate. The litmus_task_active() API automates the catching of signals that indicate that the RT task should terminate.
