How to request multiply MSI interrupts?

Ok!

it means my LATTICE_pci_intr_handler function handle all the MSI(0-7) GENERATED IRQ.

But let assume I want to test my CAN and UART by a simple function to make sure the appropriate function will be called depending on which device assert the Interrupt.

void testCAN() { printf ("Called by CAN BUS!\n"); } and

void testUART() { printf ("Called by UART!\n"); } How can I implemented these 2 functions within the Interrupt Handler or should I simply test the IRQ Number and called the related function ??

0--CAN

1--UART
