[PATCH 3/5] KVM: ARM: vgic: Fix sgi dispatch problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Haibin Wang <wanghaibin.wang@xxxxxxxxxx>

When dispatch SGI(mode == 0), that is the vcpu of VM should send
sgi to the cpu which the target_cpus list.
So, there must add the "break" to branch of case 0.
