8config INSMOD
9	bool "insmod"
10	default n
11	help
12	  insmod is used to load specified modules in the running kernel.
13
14config FEATURE_INSMOD_VERSION_CHECKING
15	bool "Module version checking"
16	default n
17	depends on INSMOD && FEATURE_2_4_MODULES
18	help
19	  Support checking of versions for modules.  This is used to
20	  ensure that the kernel and module are made for each other.
21
22config FEATURE_INSMOD_KSYMOOPS_SYMBOLS
23	bool "Add module symbols to kernel symbol table"
24	default n
25	depends on INSMOD && FEATURE_2_4_MODULES
26	help
27	  By adding module symbols to the kernel symbol table, Oops messages
28	  occuring within kernel modules can be properly debugged.  By enabling
29	  this feature, module symbols will always be added to the kernel symbol
30	  table for properly debugging support.  If you are not interested in
31	  Oops messages from kernel modules, say N.
32
33config FEATURE_INSMOD_LOADINKMEM
34	bool "In kernel memory optimization (uClinux only)"
35	default n
36	depends on INSMOD && FEATURE_2_4_MODULES
37	help
38	  This is a special uClinux only memory optimization that lets insmod
39	  load the specified kernel module directly into kernel space, reducing
40	  memory usage by preventing the need for two copies of the module
41	  being loaded into memory.
42
43config FEATURE_INSMOD_LOAD_MAP
44	bool "Enable load map (-m) option"
45	default n
46	depends on INSMOD && ( FEATURE_2_4_MODULES || FEATURE_2_6_MODULES )
47	help
48	  Enabling this, one would be able to get a load map
49	  output on stdout. This makes kernel module debugging
50	  easier.
51	  If you don't plan to debug kernel modules, you
52	  don't need this option.
53
54config FEATURE_INSMOD_LOAD_MAP_FULL
55	bool "Symbols in load map"
56	default y
57	depends on FEATURE_INSMOD_LOAD_MAP
58	help
59	  Without this option, -m will only output section
60	  load map.  With this option, -m will also output
61	  symbols load map.
62
63config RMMOD
64	bool "rmmod"
65	default n
66	help
67	  rmmod is used to unload specified modules from the kernel.
68
69config LSMOD
70	bool "lsmod"
71	default n
72	help
73	  lsmod is used to display a list of loaded modules.
74
75config FEATURE_LSMOD_PRETTY_2_6_OUTPUT
76	bool "lsmod pretty output for 2.6.x Linux kernels "
77	default n
78	depends on LSMOD
79	help
80	  This option makes output format of lsmod adjusted to
81	  the format of module-init-tools for Linux kernel 2.6.
82
83config MODPROBE
84	bool "modprobe"
85	default n
86	help
87	  Handle the loading of modules, and their dependencies on a high
88	  level.
89
90	  Note that in the state, modprobe does not understand multiple
91	  module options from the configuration file. See option below.
92
93config FEATURE_MODPROBE_MULTIPLE_OPTIONS
94	bool
95	prompt "Multiple options parsing" if NITPICK
96	default y
97	depends on MODPROBE
98	help
99	  Allow modprobe to understand more than one option to pass to
100	  modules.
101
102	  This is a WIP, while waiting for a common argument parsing
103	  common amongst all BB applets (shell, modprobe, etc...) and
104	  adds around 600 bytes on x86, 700 bytes on ARM. The code is
105	  biggish and uggly, but just works.
106
107	  Saying Y here is not a bad idea if you're not that short
108	  on storage capacity.
109
110config FEATURE_MODPROBE_FANCY_ALIAS
111	bool
112	prompt "Fancy alias parsing" if NITPICK
113	default y
114	depends on MODPROBE && FEATURE_2_6_MODULES
115	help
116	  Say 'y' here to enable parsing of aliases with underscore/dash
117	  mismatch between module name and file name, along with bus-specific
118	  aliases (such as pci:... or usb:... aliases).

124	# Simulate indentation
125	bool "Support tainted module checking with new kernels"
126	default y
127	depends on INSMOD || LSMOD
128	help
129	  Support checking for tainted modules.  These are usually binary
130	  only modules that will make the linux-kernel list ignore your
131	  support request.
132	  This option is required to support GPLONLY modules.
133
134config FEATURE_2_4_MODULES
135	# Simulate indentation
136	bool "Support version 2.2.x to 2.4.x Linux kernels"
137	default y

139	help
140	  Support module loading for 2.2.x and 2.4.x Linux kernels.
141
142config FEATURE_2_6_MODULES
143	# Simulate indentation
144	bool "Support version 2.6.x Linux kernels"

147	help
148	  Support module loading for newer 2.6.x Linux kernels.
