Hi all, XEN supported last branch recording(LBR) since 2007. And KVM has supported vPMU, but hasn't support LBR for intel CPUs yet. May I ask why? Is there any considerations to implement it? Thanks. PS: I tried to google some reasons about this, but I got nothing. :( Regards, -Gonglei -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
