如何在 Debian 中为多个内核映像版本编译 DKMS 模块？

Question

我安装了 3.16 和 4.0 版的linux-image软件包。在登录期间，我可以在“高级选项”菜单项中选择要启动的内核。但是，当我安装 DKMS 模块时，它仅针对较新版本进行编译：

Setting up fglrx-modules-dkms (1:14.12-1) ...
Loading new fglrx-14.12 DKMS files...
Building only for 4.0.0-1-amd64

3.16 也安装了相关包 ( linux-headers, linux-kbuild, linux-compiler-gcc)。

为什么没有为旧内核映像编译包？我可以配置的内容，以免被编译？

您可以使用 DKMS 安装命令 (Ref:)man dkms为特定内核重建和安装模块。下面是通过删除一个内核版本的 virtualbox 模块创建的示例。

sudo dkms install <module-name>/<module-version> -k <kernel-version>

$ dkms status
vboxhost, 5.0.10, 4.2.0-21-generic, x86_64: installed
vboxhost, 5.0.10, 4.2.0-22-generic, x86_64: installed
vboxhost, 5.0.10, 4.2.0-23-generic, x86_64: installed
vboxhost, 5.0.10, 4.2.0-25-generic, x86_64: installed

$ sudo dkms remove vboxhost/5.0.10 -k 4.2.0-22-generic
...

$ dkms status
vboxhost, 5.0.10, 4.2.0-21-generic, x86_64: installed
vboxhost, 5.0.10, 4.2.0-23-generic, x86_64: installed
vboxhost, 5.0.10, 4.2.0-25-generic, x86_64: installed


$ sudo dkms install vboxhost/5.0.10 -k 4.2.0-22-generic
