Gregory Nutt 093348030e sched/: Update signal default STOP action. If waitpid was called with the WUNTRACED then wake up waitpid. Also fix some compile problems.. How did this work before? 2018-09-02 13:51:52 -06:00

Gregory Nutt e24f281401 This commit adds a new internal interfaces and fixes a problem with three APIs in the SMP configuration. The new internal interface is sched_cpu_pause(tcb). This function will pause a CPU if the task associated with 'tcb' is running on that CPU. This allows a different CPU to modify that OS data stuctures associated with the CPU. When the other CPU is resumed, those modifications can safely take place. 
The three fixes are to handle cases in the SMP configuration where one CPU does need to make modifications to TCB and data structures on a task that could be running running on another CPU.  Those three cases are task_delete(), task_restart(), and execution of signal handles.  In all three cases the solutions is basically the same:  (1) Call sched_cpu_pause(tcb) to pause the CPU on which the task is running, (2) perform the necessary operations, then (3) call up_cpu_resume() to restart the paused CPU.

Gregory Nutt e879d0f423 Move scheduler instrumentation hooks out of sched.h (where they seem like application interfaces) and into nuttx/sched.h where it is clare that these are OS internal interfaces. 2016-03-16 11:00:31 -06:00

Gregory Nutt 72d3920295 Rename cpuset_t to cpu_set_t which is the type used in some non-standard Linux/GNU interfaces. Move definitions of cpu_set_t to include/sys/types.h. Add prototypes for sched_setaffinity(), sched_getaffinity(), pthread_attr_setaffinity_np(), pthread_attr_getaffinity_np(), pthread_setaffinity_np(), and pthread_getaffinity_np(). No implementation is yet in place. 2016-02-19 15:57:07 -06:00
