Managing and Developing Dynamically Loadable Kernel Modules

Managing Dynamically Loadable Kernel Modules

Chapter 12506

kmsystem (1M) Provides an interface to set and get a module’s

planned conﬁguration attributes prior to kernel or

module conﬁguration. Values and attributes

displayed and set with kmsystem will be used to

build a new kernel or module.

• -b

value

option - sets the planned loading phase

of the speciﬁed module.

value

can be 1

(BOOT1), 2 (BOOT2), i (INIT), or a (AUTO),

indicating that once the module is conﬁgured

and registered with the kernel, it should be

loaded during phase 1, phase 2, init, or on

demand, respectively.

• -c

value

option – assigns a value (y or n) to the

conﬁguration flag of the speciﬁed module in

preparation for the next kernel or module

conﬁguration. “y” indicates that the module will

be conﬁgured into the kernel.

• -l option – assigns a value (y or n) to the

loadable flag of the speciﬁed module in

preparation for the next kernel or module

conﬁguration. “y” indicates that the module will

be built as dynamically loadable.

• -q option – prints the values of the planned

conﬁguration attributes of the speciﬁed module.

Prints a - (signiﬁes “does not apply”) when the

attribute does not apply to the type of module.

• no options or -S option only – prints the values

of the planned conﬁguration attributes of all

modules. Prints a “-” when the attribute does

not apply to the type of module.
