Type:void

Parameter:

Type	Parameter	Name
struct cpuinfo_x86 *	c

126

Access to machine-specific registers (available on 586 and better only)* Note: the rd* operations modify the parameters directly (without using* pointer indirection), this allows gcc to optimize better(MSR_IA32_VMX_PROCBASED_CTLS, vmx_msr_low, vmx_msr_high)

127

msr_ctl = vmx_msr_high | vmx_msr_low

129

If msr_ctl & X86_VMX_FEATURE_PROC_CTLS_TPR_SHADOW Then set_cpu_cap(c, Intel TPR Shadow )

If msr_ctl & X86_VMX_FEATURE_PROC_CTLS_VNMI Then set_cpu_cap(c, Intel Virtual NMI )
