In IPIC, the 8 MSI interrupts is handled as level intrrupt. 
I just provide a versatile in case it is changed.

Level ? Are you sure ? MSIs are by definition edge interrupts... Or
do 
you have some weird logic that asserts a level input until you go ack 
something ? Sounds weird...

The second one.
The MSI is edge interrupt. The 256 MSI interrupts are divided into 8
groups. Each group can generate a interrupt to core. This interrupts are
level and asserted untile ack MSI interrupt. A little weird.
