Make it useful on non-x86. Thanks for taking this and doing the heavy lifting to get it upstream! I wrote the original SMI detector really for RT debug purposes as we had OEM systems that would generate large latencies and it was easier to prove the point with nice graphs showing where the BIOS was injecting unwanted SMIs. Glad to see the work being done to make it more generic in nature. Maybe I'll come back with some ARM patches ;) Actually this exercise was very informative because it has helped shape my input on ARMv8 designs. I'm very keen to get away from a world in which world+dog feature is implemented inside an SMI-like context. It should be done via a dedicated management processor (on-chip) instead.
