From a64003da0ef8e135cda678eb2c8a6f0baf4a9f35 Mon Sep 17 00:00:00 2001 From: Tiezhu Yang Date: Tue, 26 Mar 2024 20:11:30 +0800 Subject: irqchip/loongson-eiointc: Set CPU affinity only on SMP machines for LoongArch According to the code comment of "struct irq_chip", the member "irq_set_affinity" is to set the CPU affinity on SMP machines, so define and call eiointc_set_irq_affinity() only under CONFIG_SMP.
