kam_driver LQ Newbie Registered: Jul 2012 Posts: 4 Rep:	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. Regrads,
