3.5. Displaying information about kernel modules

Prerequisites

• The kmod package is installed.

Procedure

• Display information about any kernel module:

  $ modinfo <KERNEL_MODULE_NAME>

  For example:

  $ modinfo virtio_net
  
  filename:       /lib/modules/6.12.0-55.9.1.el10_0.x86_64/kernel/drivers/net/virtio_net.ko.xz
  license:        GPL
  description:    Virtio network driver
  rhelversion:    9.0
  srcversion:     8809CDDBE7202A1B00B9F1C
  alias:          virtio:d00000001v*
  depends:        net_failover
  retpoline:      Y
  intree:         Y
  name:           virtio_net
  vermagic:       6.12.0-55.9.1.el10_0.x86_64 SMP mod_unload modversions
  …​
  parm:           napi_weight:int
  parm:           csum:bool
  parm:           gso:bool
  parm:           napi_tx:bool

  You can query information about all available modules, regardless of whether they are loaded. The parm entries show parameters the user is able to set for the module, and what type of value they expect.

  注意

  When entering the name of a kernel module, do not append the .ko.xz extension to the end of the name. Kernel module names do not have extensions. However, their corresponding files do.
