我猜 lspci 将是执行此操作的工具，但我似乎找不到任何识别输出。有没有办法从命令行知道机器上是否存在 Thunderbolt 端口？
我知道我有一台计算机有 Thunderbolt 端口，lspci 显示如下：

答案1
至少在我的系统上，对于 Thunderbolt 3，如果没有插入任何东西，则 lshw 和 lsusb 是看不到它的（我确实看到了 USB3 端口）。我有一台 Clevo N131WU 笔记本电脑，您可以从 System76 和 Tuxedo 等供应商处购买。
也就是说，模块已加载：
[tara@tuxmonster ~]$ lsmod | grep 雷声 英特尔_wmi_thunderbolt 16384 0 wmi 28672 1 intel_wmi_thunderbolt [塔拉@tuxmonster ~]$
我仔细检查了我的台式计算机，它没有 Thunderbolt，但运行相同的发行版和内核（Arch，4.18），并且 Thunderbolt 驱动程序未加载在桌面上。
答案2
在 Mac 硬件上，Thunderbolt 热插拔主要由操作系统管理，因此 Thunderbolt 控制器始终可见。
但在 x86 PC 硬件上，Thunderbolt（至少是 Thunderbolt 1）往往由 ACPI 固件管理，并且热插拔的处理方式与标准 PCIe 热插拔事件类似。因此，如果未连接任何设备，Thunderbolt 总线对于操作系统来说是完全不可见的。但是，当您将某些东西连接到它时，从 Linux 的角度来看，许多桥接设备就会突然出现：您将看到大量输出，dmesg因为资源被分配给 Thunderbolt 总线和其中的设备。
Thunderbolt 3 可能会被检测到，因为它与 USB Type-C 连接器共存，因此可能在 Type-C 配置数据中可见。但是，我目前无法访问任何具有 Thunderbolt 3 的系统，因此我现在无法验证这一点。
答案3
Thunderbolt 控制器可能并未完全隐藏。lspci未列出 Thunderbolt 控制器，因为其供应商和设备 ID 为FFFF:FFFF。我的叉子pciutils通过检查其他寄存器来检测此类隐藏的 PCI 设备。
要确定该设备是 Thunderbolt 控制器，请查找 ID=1234 的供应商特定 PCIe 扩展功能。我不确定非 Intel Thunderbolt 或 USB4 控制器的 ID 是否为 1234。
sudo lspci -nnvvv | perl -0777 -nE 'while (/^([^\t\n].*\n)(\t.*\n)*?(\tCapabilities.* Express .*\n)(\t.*\n)*?(\t.*ID=1234.*\n)/mg) { print $1 . $3 }'

您可以更改命令以删除下游和端点设备。上面结果中列出的最后一个设备来自隐藏的 GC-ALPINE RIDGE。对于固件中不支持 Thunderbolt 的 PC 中基于 Alpine Ridge 的 Thunderbolt 3 附加卡，UEFI Shell 中的以下命令可以取消隐藏 Thunderbolt 控制器的 USB 控制器。这些命令假定 Thunderbolt 控制器具有 PCI 总线 0x10。
mm 0010000054C 00 -w 1 -PCIE -n
mm 0010000054C 0D -w 1 -PCIE -n
mm 00100000548 -w 1 -PCIE -n
当然，操作系统需要重新枚举 PCI 设备，因为 UEFI 没有枚举隐藏设备。对于基于 Titan Ridge 的 Thunderbolt 3 附加卡，默认情况下不隐藏 USB 控制器。通常，如果连接了 USB-C 设备，Thunderbolt 控制器应自行取消隐藏。
