2009-03-24KVM: SVM: Move EFER and MSR constants to generic x86 codeAlexander Graf1-1/+1
MSR_EFER_SVME_MASK, MSR_VM_CR and MSR_VM_HSAVE_PA are set in KVM specific headers. Linux does have nice header files to collect EFER bits and MSR IDs, so IMHO we should put them there. While at it, I also changed the naming scheme to match that of the other defines.

2008-12-31x86: cpu_emergency_svm_disable() functionEduardo Habkost1-0/+8
This function can be used by the reboot or kdump code to forcibly disable SVM on the CPU. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2008-12-31KVM: SVM: move svm_hardware_disable() code to asm/virtext.hEduardo Habkost1-0/+14
Create cpu_svm_disable() function. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2008-12-31KVM: SVM: move has_svm() code to asm/virtext.hEduardo Habkost1-0/+41
Use a trick to keep the printk()s on has_svm() working as before. gcc will take care of not generating code for the 'msg' stuff when the function is called with a NULL msg argument. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2008-12-31x86: cpu_emergency_vmxoff() functionEduardo Habkost1-0/+23
Add cpu_emergency_vmxoff() and its friends: cpu_vmx_enabled() and __cpu_emergency_vmxoff(). Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2008-12-31x86: asm/virtext.h: add cpu_vmxoff() inline functionEduardo Habkost1-0/+15
Unfortunately we can't use exactly the same code from vmx hardware_disable(), because the KVM function uses the __kvm_handle_fault_on_reboot() tricks. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2008-12-31KVM: VMX: move cpu_has_kvm_support() to an inline on asm/virtext.hEduardo Habkost1-0/+31
It will be used by core code on kdump and reboot, to disable vmx if needed. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
