如何检查我是否拥有 Thunderbolt x4 或 x2？[复制]

  • 772

我有一个安装了 Ubuntu 的戴尔 XPS 13。我想知道它是否具有 PCIe x4 或 x2。

编辑 1：我已经知道它是 Thunderbolt，只是不知道它有多少条 PCIe 通道。

编辑2：这是我尝试建议的命令后得到的。

$ sudo dmidecode | grep PCI
PCI is supported
Type: x16 PCI Express
Type: x1 PCI Express
Type: x1 PCI Express
Type: x1 PCI Express
Type: x1 PCI Express
Type: x1 PCI Express
Type: x1 PCI Express
Type: 32-bit PCI
    SA - PCIe Version

编辑3：尝试后， sudo lspci -vv | grep -E 'PCI 网桥|LnkCap'

00:1c.0 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port (rev f1) (prog-if 00 [Normal decode])
    LnkCap: Port #1, Speed 8GT/s, Width x2, ASPM not supported, Exit Latency L0s unlimited, L1 <16us
00:1c.4 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #5 (rev f1) (prog-if 00 [Normal decode])
    LnkCap: Port #5, Speed 8GT/s, Width x1, ASPM L1, Exit Latency L0s <1us, L1 <16us
00:1c.5 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #6 (rev f1) (prog-if 00 [Normal decode])
    LnkCap: Port #6, Speed 8GT/s, Width x1, ASPM L1, Exit Latency L0s <1us, L1 <16us
    LnkCap: Port #0, Speed 2.5GT/s, Width x1, ASPM L0s L1, Exit Latency L0s <4us, L1 <64us
    LnkCap: Port #0, Speed 5GT/s, Width x1, ASPM L0s L1, Exit Latency L0s unlimited, L1 <64us

    在终端中输入sudo dmidecode | grep PCI它，它会告诉您您拥有哪些 Pci-e 插槽。

    编辑：这应该以间接的方式工作。输入sudo lspci -vv | grep -E 'PCI bridge|LnkCap'终端，它应该会显示如下内容：

    00:14.4 PCI bridge: Advanced Micro Devices, Inc. [AMD] FCH PCI Bridge (rev 40) (prog-if 01 [Subtractive decode])
00:15.0 PCI bridge: Advanced Micro Devices, Inc. [AMD] Hudson PCI to PCI bridge (PCIE port 0) (prog-if 00 [Normal decode])
        LnkCap: Port #247, Speed 5GT/s, Width x1, ASPM L0s L1, Exit Latency L0s <64ns, L1 <1us
    Capabilities: [b0] Subsystem: Advanced Micro Devices, Inc. [AMD] Hudson PCI to PCI bridge (PCIE port 0)
00:15.1 PCI bridge: Advanced Micro Devices, Inc. [AMD] Hudson PCI to PCI bridge (PCIE port 1) (prog-if 00 [Normal decode])
        LnkCap: Port #1, Speed 5GT/s, Width x1, ASPM L0s L1, Exit Latency L0s <64ns, L1 <1us
    Capabilities: [b0] Subsystem: Advanced Micro Devices, Inc. [AMD] Hudson PCI to PCI bridge (PCIE port 1)
        LnkCap: Port #0, Speed 2.5GT/s, Width x1, ASPM L0s L1, Exit Latency L0s unlimited, L1 unlimited

    现在只需检查哪个版本与您在这里的规格相对应，您应该一切顺利。
