Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
struct cpuinfo_x86 * | c |
981 | If Max extended CPUID function supported: >= 0x80000008 Then |
984 | x86_virt_bits = eax >> 8 & 0xff |
985 | x86_phys_bits = eax & 0xff |
988 | Else if cpu_has(c, Physical Address Extensions ) || cpu_has(c, 36-bit PSEs ) Then x86_phys_bits = 36 |
