Emulate cmpxchg8b atomically on i386. This is required to avoid a guest pte walker from seeing a splitted write. [avi: make it compile] Signed-off-by: NMarcelo Tosatti <mtosatti@redhat.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>

This patch adds code to emulate the access to the cr8 register to the x86 instruction emulator in kvm. This is needed on svm, where there is no hardware decode for control register access.

Instead of each subarch doing its own thing, add an API for queuing an injection, and manage failed exception injection centerally (i.e., if an inject failed due to a shadow page fault, we need to requeue it). Signed-off-by: NAvi Kivity <avi@qumranet.com>

Previous patches have removed the dependency on cr2; we can now stop passing it to the emulator and rename uses to 'memop'. Signed-off-by: NSheng Yang <sheng.yang@intel.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>

Non-x86 archs don't need this mechanism. Move it to arch, and keep its interface in common. Signed-off-by: NZhang Xiantao <xiantao.zhang@intel.com> Acked-by: NCarsten Otte <cotte@de.ibm.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>

The current cpuid management suffers from several problems, which inhibit passing through the host feature set to the guest: - No way to tell which features the host supports While some features can be supported with no changes to kvm, others need explicit support. That means kvm needs to vet the feature set before it is passed to the guest. - No support for indexed or stateful cpuid entries Some cpuid entries depend on ecx as well as on eax, or on internal state in the processor (running cpuid multiple times with the same input returns different output). The current cpuid machinery only supports keying on eax. - No support for save/restore/migrate The internal state above needs to be exposed to userspace so it can be saved or migrated. This patch adds extended cpuid support by means of three new ioctls: - KVM_GET_SUPPORTED_CPUID: get all cpuid entries the host (and kvm) supports - KVM_SET_CPUID2: sets the vcpu's cpuid table - KVM_GET_CPUID2: gets the vcpu's cpuid table, including hidden state [avi: fix original KVM_SET_CPUID not removing nx on non-nx hosts as it did before] Signed-off-by: NDan Kenigsberg <danken@qumranet.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>

Split kvm_arch_vcpu_create() into kvm_arch_vcpu_create() and kvm_arch_vcpu_setup(), enabling preemption notification between the two. This mean that we can now do vcpu_load() within kvm_arch_vcpu_setup(). Signed-off-by: NAvi Kivity <avi@qumranet.com>

This is a little more accurate (since it counts actual reloads, not potential reloads), and reverses the sense of the statistic to measure a bad event like most of the other stats (e.g. we want to minimize all counters). Signed-off-by: NAvi Kivity <avi@qumranet.com>
