[PATCH v3 00/16] KVM: arm64: GICv3 ITS emulation

[Pavel Fedin]

 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.
