Subject: [PATCH RFC 10/39] KVM: x86/xen: support upcall vector
Date: Wed, 20 Feb 2019 20:15:40 +0000	[thread overview]
Message-ID: <20190220201609.28290-11-joao.m.martins@oracle.com> (raw)
In-Reply-To: <20190220201609.28290-1-joao.m.martins@oracle.com>

From: Ankur Arora <ankur.a.arora@oracle.com>

Add support for HVM_PARAM_CALLBACK_VIA_TYPE_VECTOR and
HVM_PARAM_CALLBACK_VIA_TYPE_EVTCHN upcall. Some Xen upcall variants do
not have an EOI for received upcalls. We handle that by directly
injecting the interrupt in the VMCS instead of going through the
LAPIC.

Note that the route @vcpu field represents the vcpu index and not a vcpu
id. The vcpu_id is architecture specific e.g. on x86 it's set to the
apic id by userspace.
