[rtl] Problem with IRQ

[Alex Montecinos L.]

Hello:

I have followed many advice in the list of mail and profit not to install
an interruption for the parallel port 

In / proc/interrupts it does not appear IRQ 7 

That it can be happening? 

This example was lowered of the list of mail 

#define MODULE
#include <linux/module.h>
#include <linux/kernel.h>
#include
<linux/rtf.h>
#include <asm/rt_irq.h>
#include <asm/rt_time.h>
#include
<linux/rt_sched.h>
#include <asm/io.h>
#include <linux/cons.h>

#define
myfifo 0
#define size 8192
#define EPP 0x378 /* Base_addres for Paralel
Port */
#define STS EPP+1
#define CTR EPP+2
#define ADD EPP+3
#define DATA
EPP+4 /* Read Register for Extended Paralel Port */

void intr_handler()
{

  int data;
   data=inb(EPP);
   rtf_put(myfifo, (char *) &data,
sizeof(data));
}

int init_module()
{
   outb(0x3F & inb(CTR),CTR);

rtf_create(myfifo,size);
   request_RTirq(7,intr_handler);
   return
0;
}

void cleanup_module()
{
   rtf_destroy(myfifo);
   free_RTirq(7);
}

Thanks
