            Bug ID: 219774
           Summary: Interrupt Affinity Inquiry
           Product: Drivers
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Platform_x86
          Assignee: drivers_platform_x86@kernel-bugs.osdl.org
          Reporter: 553216989@qq.com
        Regression: No

Hello, I have a technical question I’d like to ask. I noticed that when an
interrupt uses both smp_affinity and effective_affinity, it is forced to bind
to the CPU specified by effective_affinity. May I ask which part of the code
makes effective_affinity override and take effect over smp_affinity? I would be
very grateful if you could help me with this. Thank you very much in advance.

The effective affinity configuration I would like to inquire about is related
to MSI interrupts.
