MSI Interrupt
Hello Every one,

I am developing Linux Device Drivers for feodra with kernel version 3.4.11-1.fc16.x86_64.

I want to enable MSI Interrupt for my device. I tried pci_enable_msi_block for 4 irws, but it was never successful.
Everytime it returned 1, which means it allocated only one IRQ for me.

Can anyone help to fix this issue ? Any example code for enabling/servicing msi interrupt in driver will be highly appreciated.

Thanks in advance.
