C++ (Cpp) issue_cpu_interrupt Examples

Example #1

File: schedule.c Project: Stimels7/toy

static void run_cpu_task(int cpu, struct cpu_task *task) {
  struct cpu_data *cpud = &cpus[cpu];
  acquire_spinlock(&cpud->lock);
  cpud->task = *task;
  cpud->task.error = ERR_BUSY;
  issue_cpu_interrupt(get_cpu_desc(cpu)->apic_id, INT_VECTOR_SCHEDULER_TASK);
  while (cpud->task.error == ERR_BUSY);
  *task = cpud->task;
  release_spinlock(&cpud->lock);
}

Example #2

File: schedule.c Project: AlexSnet/toy

  struct cpu_data *cpud = &cpus[cpu];
  acquire_spinlock(&cpud->lock, 0);
  cpud->task = *task;
  if (get_cpu() == cpu)
    handle_task_int(NULL, 0);
  else {

    issue_cpu_interrupt(cpu, INT_VECTOR_SCHEDULER_TASK);
    while (cpud->task.error == ERR_BUSY);
  }
  *task = cpud->task;
  if (task->type != CPU_TASK_SELF_HALT)
    release_spinlock(&cpud->lock);
