有关 Debian GNU/Linux 10 (buster) Linux 4.19.94-ti-r42 上的 can、can-dev 内核模块的信息

我似乎缺少几个内核模块。具体来说，can并且can_dev。当我运行modprobe can或 时，模块不会加载modprobe can-dev。

我认为这是因为模块不在目录中

[/lib/modules/4.19.94-ti-r42/kernel/drivers/net/can]$ ls
slcan.ko.xz  spi  usb  vcan.ko.xz

唯一加载的 CAN 模块是can_raw，它似乎与 SocketCAN 一起工作得很好。我的问题是我正在尝试使用价值CAN这取决于 2 个模块。

我尝试下载内核，当我运行时menuconfig，我没有看到 CAN 模块。

我不知道如何继续。

以下是菜单配置选择。

答案1

这显示模块以及我需要选择什么才能创建它们。我搜索了 can.ko 和 can-dev.ko

    Platform CAN drivers with Netlink support
    modulename: can-dev.ko
    configname: CONFIG_CAN_DEV
    Linux Kernel Configuration
    └─> Networking support
    └─> CAN bus subsystem support
    └─> CAN Device Drivers
    └─> Platform CAN drivers with Netlink support
    
    CAN bus subsystem support
    modulename: can.ko
    configname: CONFIG_CAN
    Linux Kernel Configuration
    └─> Networking support
    └─> CAN bus subsystem support

根据我收集的信息，我将不得不重新编译内核来创建模块。
