[HELP] Preemptive scheduling with suspend and resume task [s32k148evb]
Description / Steps to reproduce the issue
Hello all I am trying to implement a test for checking preemptive scheduling using tasks or pthread in nuttx for S32K148_EVB board. my approach is to take tm_preemptive_scheduling_test.c file and write a wrapper for the called functions. Another approach to achieve the resume and suspend is using semaphore as below.
int tm_thread_create(int thread_id, const char *thread_name, int priority,
int (*entry_function)(int argc, FAR char *argv[]), void *args)
{
threads[thread_id] = task_create(
thread_name, // Task Name
priority, // Task Priority
CONFIG_DEFAULT_TASK_STACKSIZE, // Task Stack Size
entry_function, // Task Function
NULL // Task Arguments
);
}
int tm_thread_suspend(int thread_id)
{
return sem_wait(&g_bench_semaphores[thread_id]);
}
void tm_thread_resume(int thread_id)
{
sem_post(&g_bench_semaphores[thread_id]);
}
void tm_thread_sleep(int sec)
{
sleep(sec);
}
for Nuttx priority i am creating the thread with priority starting for lower with lower value and higher with higher value. Main priority is 100. therefore the change in code tm_preemptive_scheduling_test.c is
/* Create thread 0 at priority 10. */
tm_thread_create(0, 6, tm_preemptive_thread_0_entry);
/* Create thread 1 at priority 9. */
tm_thread_create(1, 7, tm_preemptive_thread_1_entry);
/* Create thread 2 at priority 8. */
tm_thread_create(2, 8, tm_preemptive_thread_2_entry);
/* Create thread 3 at priority 7. */
tm_thread_create(3, 9, tm_preemptive_thread_3_entry);
/* Create thread 4 at priority 6. */
tm_thread_create(4, 10, tm_preemptive_thread_4_entry);
Expected behavior is all 5 thread 0 to thread 4 is in suspend state. (waiting for semaphore) thread_report (prio:highest) goes to sleep thread 0 (prio:6) resume (semaphore release)
release the semaphore of thread 1 thread 1 (prio:7) resume (semaphore release) release the semaphore of thread 2 thread 2 (prio:8) resume (semaphore release) release the semaphore of thread 3 thread 3 (prio:9) resume (semaphore release) release the semaphore of thread 4 thread 4 (prio:10) counter4++; suspend (waiting for semaphore)
thread 3 (prio:9) counter3++; suspend (waiting for semaphore)
thread 2 (prio:8) counter2++; suspend (waiting for semaphore)
thread 1 (prio:7) counter1++; suspend (waiting for semaphore)
thread 0 (prio:6) counter0++; release the semaphore of thread 1 ----> start from top again until sleep for thread_report (prio:highest) expires
Observed behaviour all 5 thread 0 to thread 4 is in suspend state. (waiting for semaphore) thread_report (prio:highest) goes to sleep thread 0 (prio:6) resume (semaphore release)
release the semaphore of thread 1 thread 1 (prio:7) resume (semaphore release) release the semaphore of thread 2 thread 2 (prio:8) resume (semaphore release) release the semaphore of thread 3 thread 3 (prio:9) resume (semaphore release) release the semaphore of thread 4 thread 4 (prio:10) counter4++; suspend (waiting for semaphore) release the semaphore of thread 4
thread 4 (prio:10) counter4++;
thread 4 (prio:10) counter4++;
thread 4 (prio:10) counter4++;
....until sleep for thread_report (prio:highest) expires
