2008-07-20KVM: SVM: add tracing support for TDP page faultsJoerg Roedel
To distinguish between real page faults and nested page faults they should be traced as different events. This is implemented by this patch. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-04-27KVM: Add trace markersFeng (Eric) Liu
Trace markers allow userspace to trace execution of a virtual machine in order to monitor its performance. Signed-off-by: Feng (Eric) Liu <eric.e.liu@intel.com> Signed-off-by: Avi Kivity <avi@qumranet.com>

2008-01-30KVM: Portability: Move kvm_fpu to asm-x86/kvm.hChristian Ehrhardt
This patch moves kvm_fpu asm-x86/kvm.h to allow every architecture to define an own representation used for KVM_GET_FPU/KVM_SET_FPU.

2008-01-30KVM: Enhance guest cpuid managementDan Kenigsberg
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: Dan Kenigsberg <danken@qumranet.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
