[okl4-developer] Interrupts

[Sebastian Huß]

Hi,

 

I'm trying to implement some interrupt handling, but my approaches don't work yet.

 

First approach: using the [irq_handler] - flag in the corresponding idl4-file

The correct server code is generated and I have the handler-function:

 

void

testdriver_irq_handler(L4_ThreadId_t partner)

{

    printf("IRQ%d, function %d is called!\n", (int)L4_ThreadNo(partner), funcNum);

}

 

 

int main(int argc, char **argv)

{

  L4_ThreadId_t main_tid;

 

  main_tid = thread_l4tid(env_thread(iguana_getenv("MAIN")));

  

  hardware_register_interrupt(main_tid, 11);

    

  printf("<===== Testdriver Started =====>\n");

  testdriver_server_loop();

  assert(!"Shouldn't reach here\n");

}

 

I let it all run in a modified qemu where I can initiate interrupts (and this works with another flavor of L4),

but no interrupts get through to my irq_handler.

 

In another attempt I dismissed the middle-man (the server_loop and the irq_handler-function)

And implemented according to another example here in the mailing list, still no results.

 

 

int main(int argc, char **argv)

{

  L4_ThreadId_t main_tid;

  L4_ThreadId_t from_tid;

  main_tid = thread_l4tid(env_thread(iguana_getenv("MAIN")));

  

  hardware_register_interrupt(main_tid, 11);

  

  printf("<===== Testdriver Started =====>\n");

  

  for(;;)

  {

      L4_Wait(&from_tid);

      printf("from_tid %d is called!\n", (int)L4_ThreadNo(from_tid));      

  }

}

 

 

Additionally, I tried all this with the following (to see anything), without results.

 

for(int i=0;i<45;i++)

{

  hardware_register_interrupt(main_tid, i);

}

 

I think I must be missing something, but I found nothing even grepping through the sources.

 

 

Thanks in advance,

Sebastian
