Como posso verificar se tenho Thunderbolt x4 ou x2? [duplicado]

Question

Eu tenho um Dell XPS 13 no qual eu instalei o Ubuntu. Eu gostaria de saber se tem PCIe x4 ou x2.

Editar 1: Eu já sei que é Thunderbolt, só não sei quantas pistas PCIe tem.

Editar 2: Foi o que consegui depois de tentar o comando sugerido.

$ 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

Editar 3: Depois de tentar, sudo lspci -vv | grep -E 'ponte PCI | 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

    

Answer 1

Digite isto em um terminal sudo dmidecode | grep PCI , ele informará quais slots Pci-e você possui.

Edit: Isso deve funcionar de forma indireta. Digite sudo lspci -vv | grep -E 'PCI bridge|LnkCap' em um terminal para mostrar algo assim:

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

Agora, basta verificar qual versão corresponde às especificações que você tem aqui e você deve estar bem para ir.
