Type:void

Parameter:

Type	Parameter	Name
struct cpuinfo_x86 *	c

31

If CPUID functions returning a single datum >= 0xC0000001 Then

32

tmp = cpuid_edx(0xC0000001)

35

If (tmp & (ACE_PRESENT | ACE_ENABLED)) == ACE_PRESENT Then

36

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_ZHAOXIN_FCR57, lo, hi)

38

lo |= MSR_ZHAOXIN_FCR

39

wrmsr(MSR_ZHAOXIN_FCR57, lo, hi)

40

pr_info("CPU: Enabled ACE h/w crypto\n")

44

If (tmp & (RNG_PRESENT | RNG_ENABLED)) == RNG_PRESENT Then

45

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_ZHAOXIN_FCR57, lo, hi)

47

lo |= MSR_ZHAOXIN_RNG

48

wrmsr(MSR_ZHAOXIN_FCR57, lo, hi)

49

pr_info("CPU: Enabled h/w RNG\n")

56

x86_capability[CPUID_C000_0001_EDX] = cpuid_edx(0xC0000001)

59

If CPU family >= 0x6 Then set_cpu_cap(c, REP microcode works well )

62

cpu_detect_cache_sizes(c)
