How many MSIs from PCIe does "Altera MSI to GIC generator" support?

How many MSIs from PCIe does "Altera MSI to GIC generator" support? I'd like to support at leas eight of MSIs. And I'd like to connect directly the eight factors of MSI interrupt with GIC in parallel. Is it possible? Thanks in advanceKushal

I spoke with an engineer that is much more familiar with this hardware and he said that it supports 8 MSI interrupts in parallel. I'm not familiar with MSIs but the engineer said that this hardware supports up to 32 continuous addressable memory so if you want to have non-continuous you would just use multiple hardware blocks to separate out the vectors in the memory space at the expense of consuming more than interrupts. 

 

Let me know if that doesn't make sense or if you have more questions.
