12	config FEATURE_2_4_MODULES
13	bool "Support version 2.2/2.4 Linux kernels"
14	default n
15	depends on INSMOD || RMMOD || LSMOD
16	select PLATFORM_LINUX
17	help
18	Support module loading for 2.2.x and 2.4.x Linux kernels.
19	This increases size considerably. Say N unless you plan
20	to run ancient kernels.
21
22	config FEATURE_INSMOD_TRY_MMAP
23	bool "Try to load module from a mmap'ed area"
24	default n
25	depends on INSMOD || MODPROBE_SMALL
26	select PLATFORM_LINUX
27	help
28	This option causes module loading code to try to mmap
29	module first. If it does not work (for example,
30	it does not work for compressed modules), module will be read
31	(and unpacked if needed) into a memory block allocated by malloc.
32
33	The only case when mmap works but malloc does not is when
34	you are trying to load a big module on a very memory-constrained
35	machine. Malloc will momentarily need 2x as much memory as mmap.
36
37	Choosing N saves about 250 bytes of code (on 32-bit x86).
38
39	config FEATURE_INSMOD_VERSION_CHECKING
40	bool "Enable module version checking"
41	default n
42	depends on FEATURE_2_4_MODULES && (INSMOD || MODPROBE)
43	select PLATFORM_LINUX
44	help
45	Support checking of versions for modules. This is used to
46	ensure that the kernel and module are made for each other.
47
48	config FEATURE_INSMOD_KSYMOOPS_SYMBOLS
49	bool "Add module symbols to kernel symbol table"
50	default n
51	depends on FEATURE_2_4_MODULES && (INSMOD || MODPROBE)
52	select PLATFORM_LINUX
53	help
54	By adding module symbols to the kernel symbol table, Oops messages
55	occuring within kernel modules can be properly debugged. By enabling
56	this feature, module symbols will always be added to the kernel symbol
57	table for proper debugging support. If you are not interested in
58	Oops messages from kernel modules, say N.
59
60	config FEATURE_INSMOD_LOADINKMEM
61	bool "In kernel memory optimization (uClinux only)"
62	default n
63	depends on FEATURE_2_4_MODULES && (INSMOD || MODPROBE)
64	select PLATFORM_LINUX
65	help
66	This is a special uClinux only memory optimization that lets insmod
67	load the specified kernel module directly into kernel space, reducing
68	memory usage by preventing the need for two copies of the module
69	being loaded into memory.
70
71	config FEATURE_INSMOD_LOAD_MAP
72	bool "Enable insmod load map (-m) option"
73	default n
74	depends on FEATURE_2_4_MODULES && INSMOD
75	select PLATFORM_LINUX
76	help
77	Enabling this, one would be able to get a load map
78	output on stdout. This makes kernel module debugging
79	easier.
80	If you don't plan to debug kernel modules, you
81	don't need this option.
82
83	config FEATURE_INSMOD_LOAD_MAP_FULL
84	bool "Symbols in load map"
85	default y
86	depends on FEATURE_INSMOD_LOAD_MAP && !MODPROBE_SMALL
87	select PLATFORM_LINUX
88	help
89	Without this option, -m will only output section
90	load map. With this option, -m will also output
91	symbols load map.
92
93	config FEATURE_CHECK_TAINTED_MODULE
94	bool "Support tainted module checking with new kernels"
95	default y
96	depends on (LSMOD || FEATURE_2_4_MODULES) && !MODPROBE_SMALL
97	select PLATFORM_LINUX
98	help
99	Support checking for tainted modules. These are usually binary
100	only modules that will make the linux-kernel list ignore your
101	support request.
102	This option is required to support GPLONLY modules.
103
104	config FEATURE_MODUTILS_ALIAS
105	bool "Support for module.aliases file"
106	default y
107	depends on DEPMOD || MODPROBE
108	select PLATFORM_LINUX
109	help
110	Generate and parse modules.alias containing aliases for bus
111	identifiers:
112	alias pcmcia:m*c*f03fn*pfn*pa*pb*pc*pd* parport_cs
113
114	and aliases for logical modules names e.g.:
115	alias padlock_aes aes
116	alias aes_i586 aes
117	alias aes_generic aes
118
119	Say Y if unsure.
120
121	config FEATURE_MODUTILS_SYMBOLS
122	bool "Support for module.symbols file"
123	default y
124	depends on DEPMOD || MODPROBE
125	select PLATFORM_LINUX
126	help
127	Generate and parse modules.symbols containing aliases for
128	symbol_request() kernel calls, such as:
129	alias symbol:usb_sg_init usbcore
130
131	Say Y if unsure.
132
133	config DEFAULT_MODULES_DIR
134	string "Default directory containing modules"
135	default "/lib/modules"
136	depends on DEPMOD || MODPROBE || MODPROBE_SMALL || MODINFO
137	help
138	Directory that contains kernel modules.
139	Defaults to "/lib/modules"
140
141	config DEFAULT_DEPMOD_FILE
142	string "Default name of modules.dep"
143	default "modules.dep"
144	depends on DEPMOD || MODPROBE || MODPROBE_SMALL || MODINFO
145	help
146	Filename that contains kernel modules dependencies.
147	Defaults to "modules.dep"
