I have try the kernal-3.4.6 with ipipe-core-3.4.6-arm-4.patch
when I set three same Priority tasks I found untill the tasks stop ,the
interrut founction will not run.
It same like before version kernal-2.6.35.9 with
ipipe-core-2.6.35.9-arm-4.patch
static int test_thread(void *data)
{
//phase=ctrl_mnm1221_m();
while(1)
{
if(flag)
{
printk("runting %lld\n",tt3);
flag=0;
}
SLEEP_MILLI_SEC(50);
}
return 0;
}
int irq_handle_function(int irq, void *device_id)
{
//if(phase==PH_RUNNING)
//ctrl_mnm1221_m();
rt_intr_disable(&intr_desc);
tt1=rt_timer_read();
tt3=tt1-tt2;
if(tt3>300000)
flag=1;
tt2=tt1;
rt_intr_enable(&intr_desc);
return RT_INTR_HANDLED;;
}
void taskOne(void*arg)
{
int i;
for (i=0; i < 0xffff; i++)
{
printk("Iam taskOneand global = %d................\n", tt3);
}
}
void taskTwo(void*arg)
{
int i;
for (i=0; i < 0xffff; i++)
{
printk("Iam taskTwo global = %d................\n", tt3);
}
}
void taskThree(void*arg)
{
int i;
for (i=0; i < 0xffff; i++)
{
printk("Iam taskThree global = %d................\n", tt3);
}
}
static int __init rtex_init(void){
irq= gpio_to_irq(MY_GPIO2_14);
/*err=request_irq(irq, irq_handle_function, 0, "rtex", (void
*)&irq);
if(err)
{
printk("regist irq failure...\n");
return -EIO;
}*/
err =
rt_intr_create(&intr_desc,"MyIrq",irq,irq_handle_function,NULL,I_SHARED|I_EDGE);
/* ... */
rt_intr_enable(&intr_desc);
rt_task_create(&t1, "task1", 0, 1, 0);
rt_task_create(&t2, "task2", 0, 1, 0);/* start the two tasks */
rt_task_create(&t3, "task2", 0, 1, 0);/* start the two tasks */
rt_task_start(&t1, &taskOne, 0);
rt_task_start(&t2, &taskTwo, 0);
rt_task_start(&t2, &taskThree, 0);
}
Every 500m gpio send an interrupt.
The result like blow:
tt1=rt_timer_read();
global = tt3=tt1-tt2;
