如何在 Linux 中查找有關設備的資訊

我想在 Linux 中查找設備的以下資訊：

• 匯流排速度（例如 66 MHz）
• IRQ 設置
• 供應商辨識
• AGP 速率（例如 1x、2x、4x）
• MAC地址

我只能找到最後一個/sbin/ifconfig | grep HWaddr

如何在 Linux 中找到這些資訊？

用作lspci具有不同詳細程度的根（-vto -vvv）；最詳細的設置將顯示匯流排速度和 IRQ（我不知道 AGP 速率 - 這裡沒有帶有 AGP 圖形的機器）。

例如

lspci:

lspci -v:

對於 MAC 地址ifconfig，您可以隨意使用或ip link | grep link.
