Hello,
I am trying to register a function writh IRQ :
static irqreturn_t uart_test (int irq , void *dev_id)
{
printk("/!\\ Interruption : tx_empty\n");
return IRQ_HANDLED;
}
req=request_irq(0x18,uart_test,NULL,"uart_test",NULL);
printk("Initialisation IRQ UART : %d \n", req);
When I boot linux ppc, the req value is -38.
What is wrong ?
