Struct irq_affinity
Webthe irq affinity. The reason is setting offlining CPU as of the affinity is useless. Moreover, the smp_affinity value will be confusing when the offlining CPU come back again.

WebThe current implementation of irq_set_affinity () refuses rightfully to route an interrupt to an offline cpu. But there is a special case, where this is actually desired. Some of the ARM SoCs have per cpu timers which require setting the affinity during cpu startup where the cpu is not yet in the online mask.
WebIn this part we will continue to dive to the interrupt handling and will start with the external hardware interrupt handling. As you can remember, in the previous part we have finished with the trap_init function from the arch/x86/kernel/trap.c and the next step is the call of the early_irq_init function from the init/main.c. the huggabug club let\u0027s go to the zooWebApr 10, 2024 · affinities containing a mix of online and offline CPUs being passed to the irqchip driver.
