`evtest` 如何确定 PS/2 键盘的按键事件列表？

我有一个相当老旧的 PS/2 键盘，有 125 个键，其中一些键只发出扫描码，不与任何键码绑定。现在我想启动setkeycodes服务systemd来为这些“有问题的”键分配键码evtest。然而，运行 时，显示了一些奇怪的键码，它们与我主板上的任何（物理）键都不对应，而 F16 到 F22 键（以及为清楚起见我在这里省略的许多其他键）根本没有被提及：

Input driver version is 1.0.1
Input device ID: bus 0x11 vendor 0x1 product 0x1 version 0xab41
Input device name: "AT Translated Set 2 keyboard"
Supported events:
  Event type 0 (EV_SYN)
  Event type 1 (EV_KEY)
    Event code 1 (KEY_ESC)
    // Standard PC keycode omitted
    Event code 85 (KEY_ZENKAKUHANKAKU)
    Event code 86 (KEY_102ND)
    // F11 & F12 omitted
    Event code 89 (KEY_RO)
    Event code 90 (KEY_KATAKANA)

    Event code 155 (KEY_MAIL)
    Event code 156 (KEY_BOOKMARKS)
    Event code 157 (KEY_COMPUTER)
    Event code 158 (KEY_BACK)
    Event code 159 (KEY_FORWARD)
    Event code 163 (KEY_NEXTSONG)
    Event code 164 (KEY_PLAYPAUSE)
    Event code 165 (KEY_PREVIOUSSONG)
    Event code 166 (KEY_STOPCD)
    Event code 172 (KEY_HOMEPAGE)
    Event code 173 (KEY_REFRESH)
    Event code 183 (KEY_F13)
    Event code 184 (KEY_F14)
    Event code 185 (KEY_F15)
    // Where are F16 thru F22 (#186 thru #192)?
    Event code 217 (KEY_SEARCH)
    Event code 226 (KEY_MEDIA)

我怎样才能使缺失的 F 键出现在此列表中？并且：它们是否必须在此处列出才能使用setkeycodes？我的操作系统是 AMD64 上的 OpenSuSE Leap 15.5。
