multiple MSI interrupts from PLBv46_PCIE bridge

Hi,

 

I need to have more than one MSI interrupts from the PLBv46_PCIe bridge. In order to implement this feature apart from the MSI_request signal I need to export cfg_interrupt_di[7:0] to top level interface of the PLBv46_PCIe bridge. But I do not know if multi-vector MSI option is enabled in the PCIe endpoint netlist which is instantiated in the PLBv46_PCIe bridge. Can I get a clear answer before I proceed to do the change? Or is there any software solution?

 

Cheers

Currently only one MSI is supported. You might be able to tweak the provided source but this wouldn't be a supported flow.
