函数名称：tsx_init

函数原型：void __init tsx_init(void)

返回类型：void

参数：无

86  char arg[5] = {}
89  如果非tsx_ctrl_is_supported()则返回
92  ret等于命令行查找参数
93  如果ret大于等于0则
94  如果非字符串比较则
95  tsx_ctrl_state等于TSX_CTRL_ENABLE
96  否则如果非字符串比较则
97  tsx_ctrl_state等于TSX_CTRL_DISABLE
98  否则如果非字符串比较则
99  tsx_ctrl_state等于x86_get_tsx_auto_mode()
100  否则
101  tsx_ctrl_state等于TSX_CTRL_DISABLE
102  打印错误信息("tsx: invalid option, defaulting to off\n")
104  否则
106  如果IS_ENABLED(CONFIG_FOO) evaluates to 1 if CONFIG_FOO is set to 'y' or 'm',* 0 otherwise.(CONFIG_X86_INTEL_TSX_MODE_AUTO)则tsx_ctrl_state等于x86_get_tsx_auto_mode()
108  否则如果IS_ENABLED(CONFIG_FOO) evaluates to 1 if CONFIG_FOO is set to 'y' or 'm',* 0 otherwise.(CONFIG_X86_INTEL_TSX_MODE_OFF)则tsx_ctrl_state等于TSX_CTRL_DISABLE
110  否则tsx_ctrl_state等于TSX_CTRL_ENABLE
114  如果tsx_ctrl_state恒等于TSX_CTRL_DISABLE则
115  tsx_disable()
122  setup_clear_cpu_cap(Restricted Transactional Memory )
123  setup_clear_cpu_cap(Hardware Lock Elision )
124  否则如果tsx_ctrl_state恒等于TSX_CTRL_ENABLE则
132  tsx_enable()
138  setup_force_cpu_cap(Restricted Transactional Memory )
