大佬，不好意思又是我。现在先打算把驱动打到现在的系统上面去，先用起来再说，后续再慢慢研究怎么把驱动集成到内核里。

驱动的github：https://github.com/hanwckf/hd2312

按照驱动的大佬的的DKMS方法编译
我输入sudo apt install dkms linux-headers-$(uname -r)提示
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package linux-headers-6.6.59-ophub
E: Couldn't find any package by glob 'linux-headers-6.6.59-ophub'

可是我看/usr/src目录下是有linux-headers-6.6.59-ophub的，是放在这个目录不对，还是要其他设置？请指导一下，再次感谢。

安装header这步忽略，已经自带。

内核的补丁你本地打进去即可，或者把patch文件按仓库的说明放在固定目录即可自动添加。

输入后续的命令，仍然提示没有 kernel headers 文件
root@N1:/usr/src/hd2312-1.0# dkms build -m hd2312/1.0
Error! Your kernel headers for kernel 6.6.59-ophub cannot be found.
Please install the linux-headers-6.6.59-ophub package or use the --kernelsourcedir option to tell DKMS where it's located.

尝试指定kernel headers文件夹，也还是报错

请问大佬指点一下。

编译时找不到头文件, 可能是 /lib/modules/$(uname -r)/build 没有正确连结至 /usr/src/linux-headers-$(uname -r)

至于编译错误, 相信是你用的内核没有打开CONFIG_DVB_USB相关选项, 可以用指令'zgrep CONFIG_DVB_USB= /proc/config.gz'核查一下

我用的内核是6.1.xxx, 可以成功编译驱动:-

大佬不好意思，可以了。是我ln错了。
重新ln一下就好了
sudo ln -s /usr/src/linux-headers-6.1.116-ophub /lib/modules/6.1.116-ophub/build

现在就想想怎么编译内核的时候把驱动编译进去，这样方便后续编译固件。大佬可以指导一下嘛！非常感谢

大佬再请教一下，这打内核模块的模式，是不是升级内核模块就会失效啦？

看仓库文档第9章，编译内核时添加补丁有文档。
