  • Thread-topic: VHPI restore mechanism at save/restore
Hi,Isaku
I have a question about the mechanism for save/restore vhpi.  In current 
save/restore code, vhpi register is only saved and restored by 
vlsapic_save/load, but it maybe not enough for ensuring correctness.  IMO, we 
need to call PAL_VPS_SET_PENDING_INTERRUPT again to set it， and make cpu aware 
of its value.  Do I miss something ? :)
Thanks
Xiantao
