KVM: Add KVM_EXIT_SYSTEM_EVENT to user space API header
Currently, we don't have an exit reason to notify user space about a system-level event (for e.g. system reset or shutdown) triggered by the VCPU. This patch adds exit reason KVM_EXIT_SYSTEM_EVENT for this purpose. We can also inform user space about the 'type' and architecture specific 'flags' of a system-level event using the kvm_run structure. This newly added KVM_EXIT_SYSTEM_EVENT will be used by KVM ARM/ARM64 in-kernel PSCI v0.2 support to reset/shutdown VMs. Signed-off-by: Anup Patel <anup.patel@linaro.org> Signed-off-by: Pranavkumar Sawargaonkar <pranavkumar@linaro.org> Reviewed-by: Christoffer Dall <christoffer.dall@linaro.org> Reviewed-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
