From 8f2abe6a1e525e878bdf58f68ccd146d543fde84 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Tue, 25 Mar 2008 18:47:23 +0100 Subject: KVM: s390: sie intercept handling This path introduces handling of sie intercepts in three flavors: Intercepts are either handled completely in-kernel by kvm_handle_sie_intercept(), or passed to userspace with corresponding data in struct kvm_run in case kvm_handle_sie_intercept() returns -ENOTSUPP. In case of partial execution in kernel with the need of userspace support, kvm_handle_sie_intercept() may choose to set up struct kvm_run and return -EREMOTE. The trivial intercept reasons are handled in this patch: handle_noop() just does nothing for intercepts that don't require our support at all handle_stop() is called when a cpu enters stopped state, and it drops out to userland after updating our vcpu state handle_validity() faults in the cpu lowcore if needed, or passes the request to userland Acked-by: Martin Schwidefsky Signed-off-by: Christian Borntraeger Signed-off-by: Carsten Otte Signed-off-by: Avi Kivity --- arch/s390/kvm/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/s390/kvm/Makefile') diff --git a/arch/s390/kvm/Makefile b/arch/s390/kvm/Makefile index 0d8d1135a278..27882b35ef04 100644 --- a/arch/s390/kvm/Makefile +++ b/arch/s390/kvm/Makefile @@ -10,5 +10,5 @@ common-objs = $(addprefix ../../../virt/kvm/, kvm_main.o) EXTRA_CFLAGS += -Ivirt/kvm -Iarch/s390/kvm -kvm-objs := $(common-objs) kvm-s390.o sie64a.o +kvm-objs := $(common-objs) kvm-s390.o sie64a.o intercept.o obj-$(CONFIG_KVM) += kvm.o -- cgit v1.2.3
