Proto:static void zhaoxin_detect_vmx_virtcap(struct cpuinfo_x86 *c)

Type:void

Parameter:

Type	Parameter	Name
struct cpuinfo_x86 *	c

96

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)

97

msr_ctl = vmx_msr_high | vmx_msr_low

99

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

101

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

103

If msr_ctl & X86_VMX_FEATURE_PROC_CTLS_2ND_CTLS Then

104

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_CTLS2, vmx_msr_low, vmx_msr_high)

106

msr_ctl2 = vmx_msr_high | vmx_msr_low

107

If msr_ctl2 & X86_VMX_FEATURE_PROC_CTLS2_VIRT_APIC && msr_ctl & X86_VMX_FEATURE_PROC_CTLS_TPR_SHADOW Then set_cpu_cap(c, Intel FlexPriority )

110

If msr_ctl2 & X86_VMX_FEATURE_PROC_CTLS2_EPT Then set_cpu_cap(c, Intel Extended Page Table )
