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
提问于 2023-03-27 12:02:51
我似乎缺少了几个内核模块。具体来说，can和can_dev。当我运行modprobe can或modprobe can-dev时，这些模块不会加载。
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，它似乎可以很好地与SocketCAN一起工作。我的问题是，我试图使用ValueCAN，这取决于两个模块。
我试着下载内核，当我运行menuconfig时，看不到CAN模块。
我不知道该怎么做。
下面是menuconfig选择。

这展示了模块，以及为了创建它们我需要选择什么。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。
