Hi, On 23/12/2014 04:43, manish jaggi wrote: In gic.c, gic_update_one_lr, gic_hw_ops is called to read and write to an LR. The function gic_update_one_lr is only used to update the LRs of the current vCPU. why is read/write not done on the LRs stored in the vcpu context ? The LR array in the vCPU context is only used when to save/restore the state of the vGIC vCPU.When the vCPU is not sync, the state of this LRs is invalid. Think about the vCPU running on another pCPU. Regards, -- Julien Grall _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
