Subject: [PATCH 1/2] KVM: VMX: Introduce exit reason for receiving INIT signal on guest-mode
Date: Mon, 26 Aug 2019 13:24:48 +0300 [thread overview]
Message-ID: <20190826102449.142687-2-liran.alon@oracle.com> (raw)
In-Reply-To: <20190826102449.142687-1-liran.alon@oracle.com>
According to Intel SDM section 25.2 "Other Causes of VM Exits",
When INIT signal is received on a CPU that is running in VMX
non-root mode it should cause an exit with exit-reason of 3.
(See Intel SDM Appendix C "VMX BASIC EXIT REASONS")
This patch introduce the exit-reason definition.
