Hi, I use the kernel which version is 3.12 - rc7 . About the vgic module, there are two bugs:
The first bug is about sgi dispatching, In vgic_dispatch_sgi function, when mode == 0, that is the vcpu of VM should send sgi to the cpu of the target_cpus list. So , there must be a lack of break in switch case 0 branch.

The second bug is about GICD_CFGRn accessing. I have had this error feedback :
