标题: rk3568出厂的Debian系统PCIE3.0是x几的？
rk3568出厂的Debian系统PCIE3.0是x几的？现在我接入一个pcie板卡，能够检测到板卡，但是连接状态位宽是x1，不是x2，导致CPU和板卡通讯速率降低
问一下是什么原因？
这是lspci -vvv查到的信息

硬件是支持PCIe3.0 x 2，你要确认下你的板子是1xLane还是2xLane的。

你好，如何确认我的板子是1xLane还是2xLane的？
我的CPU板型号是TX030D
mainboard类型是35101

Hi,为什么我的3568的板子，pcie控制器显示的是3566，是不是这个原因导致我的pcie是x1
