在guest OS的视角看依然存在GIC中断控制器,只不过这个virtual GIC的实现被分为2个部分:vPE会频繁访问的virtual CPU interface被放在硬件中直接支持。而一般只需在boot up阶段setup准备好的redistributor, distributor, ITS在KVM中由软件模拟。 Guest OS写入device的MSIX消息是基于guest OS domain的,也就是device ID, e...

cpuhp_setup_state_nocalls函数,设置好CPU进行热插拔时GIC的回调函数,以便在CPU热插拔时做相应处理; set_handle_irq函数的设置很关键,它将全局函数指针handle_arch_irq指向了gic_handle_irq,而处理器在进入中断异常时,会跳转到handle_arch_irq执行,所以,可以认为它就是中断处理的入口函数了; ...
