函数名称：init_zhaoxin_cap

函数原型：static void init_zhaoxin_cap(struct cpuinfo_x86 *c)

返回类型：void

参数：

类型参数名称
struct cpuinfo_x86 *c
31  如果CPUID functions returning a single datum大于等于0xC0000001则
32  tmp等于cpuid_edx(0xC0000001)
35  如果tmp按位与ACE_PRESENT按位或ACE_ENABLED的值的值恒等于ACE_PRESENT则
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或等于MSR_ZHAOXIN_FCR
39  wrmsr(MSR_ZHAOXIN_FCR57, lo, hi)
40  打印信息("CPU: Enabled ACE h/w crypto\n")
44  如果tmp按位与RNG_PRESENT按位或RNG_ENABLED的值的值恒等于RNG_PRESENT则
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或等于MSR_ZHAOXIN_RNG
48  wrmsr(MSR_ZHAOXIN_FCR57, lo, hi)
49  打印信息("CPU: Enabled h/w RNG\n")
56  x86_capability[CPUID_C000_0001_EDX]等于cpuid_edx(0xC0000001)
59  如果CPU family 大于等于0x6则set_cpu_cap(c, REP microcode works well )
62  cpu_detect_cache_sizes(c)
