* bugfix: C-EDF, clear scheduled field of the correct CPU upon task_exitwip-timer-traceAndrea Bastoni2010-12-25
| | | | | | | | | Do not use the "scheduled_on" field to address the cpus structure within a cluster. cpus may contain less items than num_online_cpus and we may cause an out-of-bound access. Instead, use "scheduled_on" to directly access the per-cpu cpu_entry_t structure. Reported-by: Jonathan Herman <hermanjl@cs.unc.edu>
* bugfix: avoid underflow in budget_remaining()Bjoern B. Brandenburg2010-11-29
| | | | | | | budget_remaining() reports incorrect values due to the operands being switched, which leads to an integer underflow. Reported-by: Chris Kenna <cjk@cs.unc.edu>
* bugfix: fix out-of-bound array access in cedf_activate_plugin()Andrea Bastoni2010-11-29
| | | | | | | Make sure to check for maximum index value when accessing cedf_domain_t array in cedf_activate_plugin(). Reported-by: Jeremy Erickson <jerickso@cs.unc.edu>
* add optional [function@file:line] tag to TRACE() logBjoern B. Brandenburg2010-11-22
| | | | | | | | | | | Add information to each trace message that makes it easier to locate where it came from. It is disabled by default since this adds a lot of clutter. Example: 81281 P1 [gsnedf_schedule@litmus/sched_gsn_edf.c:406]: (rtspin/1483:1) blocks:0 out_of_time:0 np:0 sleep:1 preempt:0 state:0 sig:0 81282 P1 [job_completion@litmus/sched_gsn_edf.c:303]: (rtspin/1483:1) job_completion(). 81283 P1 [__add_release@litmus/rt_domain.c:344]: (rtspin/1483:2) add_release(), rel=41941764351 81284 P1 [gsnedf_schedule@litmus/sched_gsn_edf.c:453]: (rtspin/1483:2) scheduled_on = NO_CPU
* log job number in TRACE_TASK() and TRACE_CUR()Bjoern B. Brandenburg2010-11-22
| | | | | | | | | | | | | | | | For some problems it can be helpful to know which job of a task generated a log message. This patch changes TRACE_TASK to add :<jobno> to the existing (<comm>/<pid>) tag. The result is a trace such as the following, in which the third job of rtspin/1511 completes and the fourth job is added to the release queue. 137615 P0: (rtspin/1511:3) job_completion(). 137616 P0: (rtspin/1511:4) add_release(), rel=262013223089 137617 P0: (rtspin/1511:4) scheduled_on = NO_CPU The job number for non-real-time tasks is always zero.
* Bugfix: synchronize with all other CPUs before switching pluginAndrea Bastoni2010-11-20
| | | | | | | | | | | The CPU triggering the plugin switch should wait until all other CPUs are in a proper state (synch_on_plugin_switch()) before performing the actual switch. Based on the original patch from Jeremy Erickson <jerickso@cs.unc.edu>. This should solve (for most practical cases) the C-EDF-related plugin-switch problem reported on the ML.
* Improve help message for TRACE() bufferBjoern B. Brandenburg2010-11-16
| | | | | It's not being allocated per cpu anymore. Further, provide a hint to the user where to find the data in userspace.
* Make TRACE() buffer size configurableBjoern B. Brandenburg2010-11-16
| | | | | | | | | | | Let the user choose an appropriate buffer size (instead of scaling with NR_CPUS). The kfifo api requires the buffer to be a power of two, so enforce this constraint in the configuration. This fixes a previously-existing compile-time error for values of NR_CPU that are not a power of two. Based on a patch by Mac Mollison <mollison@cs.unc.edu>.
* Workaround: do not set rq->skip_clock_updateBjoern B. Brandenburg2010-11-11
| | | | | | | | | | | | | Disabling the clock update seems to be causing problems even in normal Linux, and causes major bugs under LITMUS^RT. As a workaround, just disable this "optimization" for now. Details: the idle load balancer causes tasks that suspsend to be marked with set_tsk_need_resched(). When such a task resumes, it may wrongly trigger the setting of skip_clock_update. However, a corresponding rescheduling event may not happen immediately, such that the currently-scheduled task is no longer charged for its execution time.
* Remove LITMUS^RT TRACE_BUG_ON macroBjoern B. Brandenburg2010-11-11
| | | | | | Linux now has a macro of the same name, which causes namespace collisions. Since our version is only being used in two places that haven't triggered in several years, let's just remove it.
* Avoid warning on 64bit buildsBjoern B. Brandenburg2010-11-11
| | | | | The specifier %u doesn't match sizeof() if sizeof() returns a 64bit quantity on x86_64. Always cast it to int to avoid the warning.
* Cleanup TRACE() implementationBjoern B. Brandenburg2010-11-11
| | | | | | | | | | | | | | Since the intial rebased from .24 to .32, the TRACE() implementation was a hybrid between our old ringbuffer implementation and the new generic kfifo API. This was a) ugly and b) not save for TRACE() invoctations during early boot. This patch rips out the old parts and replaces the actual buffer with a static kfifo. This also increases TRACE() buffer size considerably. As we avoid a dynamic allocation, this a larger size is less problematic for debug builds. This helps a bit with holes in the debug log if the buffer-flushing task is starved.

| | | | Call into scheduler state machine in the IPI handler.
* Implement proper remote preemption supportBjoern B. Brandenburg2010-11-11
| | | | | | | | | | | | To date, Litmus has just hooked into the smp_send_reschedule() IPI handler and marked tasks as having to reschedule to implement remote preemptions. This was never particularly clean, but so far we got away with it. However, changes in the underlying Linux, and peculartities of the ARM code (interrupts enabled before context switch) break this naive approach. This patch introduces new state-machine based remote preemption support. By examining the local state before calling set_tsk_need_resched(), we avoid confusing the underlying Linux scheduler. Further, this patch avoids sending unncessary IPIs.
* hook litmus tick function into hrtimer-driven ticksBjoern B. Brandenburg2010-11-11
| | | | | Litmus plugins should also be activated if ticks are triggered by hrtimer.
* Split out TRACE() from litmus.h and cleanup some includesBjoern B. Brandenburg2010-11-11
| | | | | | | | | | The TRACE() functionality doesn't need all of litmus.h. Currently, it's impossible to use TRACE() in sched.h due to a circular dependency. This patch moves TRACE() and friends to litmus/sched_debug.h, which can be included in sched.h. While at it, also fix some minor include ugliness that was revealed by this change.
* sched_trace: make buffer size configurableBjoern B. Brandenburg2010-11-11
| | | | | Large sched_trace buffers cause boot problems on the ARM box. Allow the user to specify smaller buffers.
* ARM: hookup LITMUS^RT system callsBjoern B. Brandenburg2010-11-11
| | | | | Includes the LITMUS^RT-specifc unistd.h extension and modifies the actual syscall table.
* ARM: Include LITMUS^RT KConfigBjoern B. Brandenburg2010-11-11
| | | | Make the ARM built aware of the LITMUS^RT-specific options.
* ARM: provide get_cycles() for RealView PB11{MP,76} and Cortex-A8Bjoern B. Brandenburg2010-11-11
| | | | | Use the CCNT register to override the default get_cycles() implementation in arch/arm/asm/timex.h. This is useful for overhead measurements and debugging.
* ARM: allow mach/timex.h to define get_cycles()Bjoern B. Brandenburg2010-11-11
| | | | | | Some platforms have access to a cycle coutner (CCNT) register in the CP15 coprocessor. This trivial change will allow such platforms to provide specialized implementations.
* C-EDF: move /proc/litmus/cluster_cache to /proc/litmus/plugins/C-EDF/clusterBjoern B. Brandenburg2010-11-11
| | | | | | | Make use of the new per-plugin proc file infrastructure to avoid littering the global namespace. While at it, also move all the relevant bits to sched_cedf.c. In the future, each plugin's parameters should be handled in the respective plugin file.
* Litmus core: refactor the implementation of /procChristopher Kenna2010-10-23

* Litmus core: per-plugin proc directoriesChristopher Kenna2010-10-23
| | | | | | Change the Litmus proc layout so that loaded plugins are visible in /proc/litmus/plugins/loaded and add Litmus functions make_plugin_proc_dir() and remove_plugin_proc_dir() to add per-plugin proc directories.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running make clean, Kbuild doesn't process the .config file, so nothing generates a platform-y variable.

To overcome this, let's not block till the host signals it has given back the virtio ring element we passed it. Instead, send the buffer to the host and return to userspace. This operation then becomes similar to how non-blocking writes work, so let's use the existing code for this path as well. This code change also ensures blocking write calls do get blocked if there's not enough room in the virtio ring as well as they don't return -EAGAIN to userspace.
