This file provides information on the module parameters of many of
|
|
the Linux watchdog drivers. Watchdog driver parameter specs should
|
|
be listed here unless the driver has its own driver-specific information
|
|
file.
|
|
|
|
|
|
See Documentation/admin-guide/kernel-parameters.rst for information on
|
|
providing kernel parameters for builtin drivers versus loadable
|
|
modules.
