As Ashok Raj has already responded, there was support for APIC-based MSI[-X] on ia64 before my patches. I personally do not know if it worked or not, my suspicion is that it didn't get much airtime due to MSI being off by default until somewhat recently. I believe MSI was working on zx1 after my patch, so I suspect it worked there before my patch as well. I can't speak to MSI-X. Mike, is your driver capable of MSI (vs. MSI-X)? As a datapoint, could you try that?
