3.2. Kernel module dependencies
Certain kernel modules sometimes depend on one or more other kernel modules. The /lib/modules/<KERNEL_VERSION>/modules.dep file contains a complete list of kernel module dependencies for the corresponding kernel version.
depmodThe dependency file is generated by the
depmodprogram, included in thekmodpackage. Many utilities provided bykmodconsider module dependencies when performing operations. Therefore, manual dependency-tracking is rarely necessary.警告The code of kernel modules executes in kernel-space in the unrestricted mode. Be cautious about the modules you are loading.

In addition to
depmod, Red Hat Enterprise Linux provides theweak-modulesscript, which is a part of thekmodpackage. Theweak-modulesscript determines the modules that are kABI-compatible with installed kernels. While checking modules kernel compatibility,weak-modulesprocesses modules symbol dependencies from higher to lower release of kernel for which they were built. It processes each module independently of the kernel release.
