Description yuboyang 2025-02-12 03:10:22 UTC
Hello, I have a technical question Iā€™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.
