Hello List,
aktually I have some disagreements with my interrupt routine for a PCI
board.
I'm writing a driver module an should react on different interrupt sources.T
he interrupt wil be generated for example by the timer. I can check the
correct interrupt levels on the PCI Bus (4V -> 0V if an interrupt occurs),b
ut my interrupt routine is not called. Maybe, and I think it's right, myc
ode has one or more failures. Please can anybody take a look on it,
I don't know whats could be wrong
In my code I create a pointer to a structure:
str_BoardInformations *BoardInformations;
void APCI1500_bh_Interrupt(void)
{
//Send a signal to from kernel to user space
send_sig(SIGIO,tsk_Current,0);
printk("APCI1500_bh_Interrupt()\n");
}
void APCI1500_Interrupt(int irq, void *dev_id, struct pt_regs *regs)
{
INT i;
BYTE b_RegValue;
ULONG ul_Status;
BoardInformations = dev_id;
printk("\nAPCI1500_Interrupt -Function\n\n\n");
/* Here starts code to reset the interrupt line */
}
To set the interrupt routine I do it like this:
(This is in my IOCTL function)
...
i =
request_irq(BoardInformations->s_BaseInformations.b_Interrupt,
APCI1500_Interrupt, SA_SHIRQ, "APCI1500", BoardInformations);
printk("Request IRQ: %d\n", i);
/*Initalization of tq_bhInterrupt*/
tq_bhInterrupt.next=NULL;
tq_bhInterrupt.sync=0;
tq_bhInterrupt.routine=APCI1500_bh_Interrupt;
if(!tsk_Current)
tsk_Current=current; /*Now current point to
the process that at open*/
...
}
Can anybody tell me, why the interrupt routine APCI1500_Interrupt isn't
called?
I need the Interrupt routine to reset the interrupt level. Without
resetting, the PC
hangs everytime an interrupt occurs :-(.
Many thanks for help.
With the best regards,
Eric Stolz
