Subject: [PATCH 3/5] KVM: ARM: vgic: Fix sgi dispatch problem
Date: Wed, 30 Apr 2014 04:15:54 -0700 [thread overview]
Message-ID: <1398856556-13199-4-git-send-email-christoffer.dall@linaro.org> (raw)
In-Reply-To: <1398856556-13199-1-git-send-email-christoffer.dall@linaro.org>
From: Haibin Wang <wanghaibin.wang@huawei.com>
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.
