2015-06-26score: Simplify <rtems/system.h>Sebastian Huber1-1/+1
Drop the <rtems/score/percpu.h> include since this file exposes a lot of implementation details.
2015-06-15Remove use ticks for statistics configure option.Joel Sherrill5-134/+33
This was obsolete and broken based upon recent time keeping changes. Thie build option was previously enabled by adding USE_TICKS_FOR_STATISTICS=1 to the configure command line. This propagated into the code as preprocessor conditionals using the __RTEMS_USE_TICKS_FOR_STATISTICS__ conditional.
2015-04-29libmisc/cpuuse: Top support for current load.Chris Johns1-195/+541
The cpuuse top command now supports the current load where the list of tasks is ordered based on the current load rather than the total cpu usage. This lets you see what is using the processor at any specific instance. The ability to sort on a range of thread values is now supported. Added memory usage stats for unified and separate workspace and C heaps as well as displaying the allocated stack space. Added a few more command keys to refresh the display, show all tasks in the system, control the lines display and a scrolling mode that does not clear the display on each refresh. Removed support for tick kernel builds. The tick support in the kernel is to be removed.

2014-05-07score: Implement forced thread migrationSebastian Huber1-1/+1
The current implementation of task migration in RTEMS has some implications with respect to the interrupt latency. It is crucial to preserve the system invariant that a task can execute on at most one processor in the system at a time. This is accomplished with a boolean indicator in the task context. The processor architecture specific low-level task context switch code will mark that a task context is no longer executing and waits that the heir context stopped execution before it restores the heir context and resumes execution of the heir task. So there is one point in time in which a processor is without a task. This is essential to avoid cyclic dependencies in case multiple tasks migrate at once. Otherwise some supervising entity is necessary to prevent life-locks. Such a global supervisor would lead to scalability problems so this approach is not used. Currently the thread dispatch is performed with interrupts disabled. So in case the heir task is currently executing on another processor then this prolongs the time of disabled interrupts since one processor has to wait for another processor to make progress. It is difficult to avoid this issue with the interrupt latency since interrupts normally store the context of the interrupted task on its stack. In case a task is marked as not executing we must not use its task stack to store such an interrupt context. We cannot use the heir stack before it stopped execution on another processor. So if we enable interrupts during this transition we have to provide an alternative task independent stack for this time frame. This issue needs further investigation.
2014-04-22score: Use common names for per-CPU variablesSebastian Huber1-6/+6
Use "cpu" for an arbitrary Per_CPU_Control variable. Use "cpu_self" for the Per_CPU_Control of the current processor. Use "cpu_index" for an arbitrary processor index. Use "cpu_index_self" for the processor index of the current processor. Use "cpu_count" for the processor count obtained via _SMP_Get_processor_count(). Use "cpu_max" for the processor maximum obtained by rtems_configuration_get_maximum_processors().
2014-04-11rtems: Rename rtems_smp_get_processor_count()Sebastian Huber1-1/+1
Rename rtems_smp_get_processor_count() in rtems_get_processor_count(). Make rtems_get_processor_count() a function in uni-processor configurations to enable ABI compatibility with SMP configurations.

2013-06-14score: Rename rtems_smp_get_number_of_processors()Sebastian Huber1-1/+1
Rename in rtems_smp_get_processor_count(). Always provide <rtems/score/smp.h> and <rtems/rtems/smp.h>. Add _SMP_Get_processor_count(). This function will be a compile time constant defined to be one on uni-processor configurations. This allows iterations over all processors without overhead on uni-processor configurations.
