How to request multiply MSI interrupts?

Hi,

Once more thanks a lot for your advice about Linux Driver Programming. Rigth now how to deal with Interrupt Service Routine because I have 8 MSI Source. Should I write 8 ISR?

Here is a piece of my code

--- Quote Start ---

------------------------------------------------------------------------------------------

/* Interrupt Handler */

void LATTICE_pci_intr_handler (int irq, void *dev_id, struct pt_regs *regs)

{

unsigned long intr_flag;

/* Lese Interrupt-Flag, um zu pruefen, ob das LATTICE PCI-Board ueberhaupt */

/* Quelle des Interrupts ist. (Moeglicherweise Shared Interrupt!) */

intr_flag = readl (LATTICE_pci_dev.virt_addr + LATTICE_INTR_REG_ADDR) & 1;

if (intr_flag) return; /* Kein Interrupt durch das LATTICE PCI-Board */

/* Hier beginnt die eigentliche Interrupt-Bearbeitung... */

printk ("LATTICE PCI-Board: Interrupt!\n");

}

........

/* Interrupt-Handler registrieren */

if (request_irq (LATTICE_pci_dev.intr_line, LATTICE_pci_intr_handler,

SA_SHIRQ, LATTICE_PCI_NAME, &LATTICE_pci_dev))

{

printk ("LATTICE PCI-Board: can't get assigned IRQ %d.\n", LATTICE_pci_dev.intr_line);

result = -EIO;

goto exit1;

}
