Subject: request_irq in a module casues kernel crash
Date: Thu, 22 Mar 2001 21:50:11 -0800 (PST) [thread overview]
Message-ID: <200103230550.VAA03749@shell9.ba.best.com> (raw)
I am trying to write a module where I am trying to register an interrupt
handler using request_irq() sample code for which appears below, when
I try to load this module, I am getting kernel panic. Anybody knows reason
why?
I have compiled the kernel with CONFIG_MODULES=y CONFIG_MODVERSIONS=y
CONFIG_KMOD=y
I am using 2.4.2-pre3 on a 860 platform.
void handler(int irq, void *dev_id, struct pt_regs * regs)
{
printk("Interrupt handler invoked for irq %d \n",irq);
}
/* load the module */
int init_module(void)
{
int result;
result = request_irq (SIU_IRQ7, my_handler,SA_INTERRUPT,
"cxeHandler",NULL);
if ( result )
printk("Interrupt not assigned");
else
printk("Interrupt assigned");
return 0;
}
/* remove the module */
void cleanup_module(void)
{
return;
}
