Yes, it is the case. I've overlooked that for some exceptions interrupts are enabled before enter_hypervisor_head(). > Can you try the patch below? I tried it, and it works like a charm for the issue. The only notice here is that, I suppose, changes are needed for exceptions taken from a guest mode. For the exceptions taken from hyp, we do not massage gic in enter_hypervisor_head. -- *Andrii Anisov* _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
