I have a server with two Intel Xeon 18-core cpus with hyper-threading enabled. I'm trying to send an IPI between cores and there are only about 5 cores which receive the interrupts. The same is happening when I'm trying to set up MSI vectors for my Ethernet driver. I've disabled x2apic and am using physical addressing mode. The max APIC id is 119 so that should be fine.
I believe I have all steps done for each AP that are mentioned in this post viewtopic.php?f=1&p=201660.

Any suggestions about what I might be missing?
