Hi,
Is it possible for ddi_intr_alloc() to return an odd value (Eg: 3,5,
7, etc) for *actualp (which is pointer to the number of interrupts
actually allocated) for MSIX?
Or would it always return a value which is power of 2?
The implementation today always returns a power of 2, last I looked.
(Hmm... that might have been for MSI rather than MSI-X.)
I would not depend on that though. It could change.
