    11 niro 532 help
    12 niro 816 Directory that contains kernel modules.

    19 niro 816 Filename that contains kernel modules dependencies.
    20     Defaults to "modules.dep"

    23     bool "Simplified modutils"

    25     help
    26 niro 816 Simplified modutils.
    27 niro 532
    28 niro 816 With this option modprobe does not require modules.dep file
    29     and does not use /etc/modules.conf file.
    30     It scans module files in /lib/modules/`uname -r` and
    31     determines dependencies and module alias names on the fly.
    32     This may make module loading slower, most notably
    33     when one needs to load module by alias (this requires
    34     scanning through module _bodies_).
    35    
    36     At the first attempt to load a module by alias modprobe
    37     will try to generate modules.dep.bb file in order to speed up
    38     future loads by alias. Failure to do so (read-only /lib/modules,
    39     etc) is not reported, and future modprobes will be slow too.
    40    
    41     NB: modules.dep.bb file format is not compatible
    42     with modules.dep file as created/used by standard module tools.
    43    
    44     Additional module parameters can be stored in
    45     /etc/modules/$module_name files.
    46    
    47     Apart from modprobe, other utilities are also provided:
    48     - insmod is an alias to modprobe
    49     - rmmod is an alias to modprobe -r
    50     - depmod generates modules.dep.bb
    51    
    52     As of 2008-07, this code is experimental. It is 14kb smaller
    53     than "non-small" modutils.

    97     This option makes output format of lsmod adjusted to
    98     the format of module-init-tools for Linux kernel 2.6.

    105 niro 532 help
    106     Handle the loading of modules, and their dependencies on a high
    107     level.
    108    
    109     Note that in the state, modprobe does not understand multiple

    118 niro 816 Say 'y' here to enable support for the 'blacklist' command in
    119     modprobe.conf. This prevents the alias resolver to resolve
    120     blacklisted modules. This is useful if you want to prevent your
    121     hardware autodetection scripts to load modules like evdev, frame
    122     buffer drivers etc.

    156     help
    157     By adding module symbols to the kernel symbol table, Oops messages
    158     occuring within kernel modules can be properly debugged. By enabling
    159     this feature, module symbols will always be added to the kernel symbol
    160     table for properly debugging support. If you are not interested in
    161     Oops messages from kernel modules, say N.

    167     help
    168     This is a special uClinux only memory optimization that lets insmod
    169     load the specified kernel module directly into kernel space, reducing
    170     memory usage by preventing the need for two copies of the module
    171     being loaded into memory.

    178     Enabling this, one would be able to get a load map
    179     output on stdout. This makes kernel module debugging
    180     easier.
    181     If you don't plan to debug kernel modules, you
    182     don't need this option.

    189 niro 816 Without this option, -m will only output section
