From 99040447cee777498c1b2125f16402b8af88355c Mon Sep 17 00:00:00 2001 From: Pranavkumar Sawargaonkar Date: Thu, 19 Jun 2014 18:06:25 +0100 Subject: kvm: Handle exit reason KVM_EXIT_SYSTEM_EVENT In-kernel PSCI v0.2 emulation of KVM ARM/ARM64 forwards SYSTEM_OFF and SYSTEM_RESET function calls to QEMU using KVM_EXIT_SYSTEM_EVENT exit reason. This patch updates kvm_cpu_exec() to handle KVM_SYSTEM_EVENT_SHUTDOWN and KVM_SYSTEM_EVENT_RESET system-level events from QEMU-side.
