Hello! > LPIs do not have an active state, at the redistributor or otherwise. Then what do they become after they were ACK'ed and before EOI'ed? I tried to google up this thing, and came up with this email: http://www.spinics.net/lists/kvm-arm/msg16032.html. It says that "SW must issue a write to EOI to clear the active priorities register, hence the CPU interface still requires an active state for LPIs". They give a link to some document which seems to be top-secret and never published, because my arch reference manual does not have section 4.8.3 named "Properties of LPI". And another thread, http://lists.xen.org/archives/html/xen-devel/2014-09/msg01141.html, says that virtual LPIs actually do have active state in LR.
