How to configure YouCompleteMe to develop kernel drivers and devices?

I would like to configure vim to crack the kernel, so I installed YouCompleteMe to automatically terminate. However, no matter what I do, it looks like I cannot configure it correctly. It does not perform semantic completion properly; It offers only the semantics already used in the current file, not even in the headers or other translation units, and if that is not possible, then ycm is pretty useless. Does anyone know how to do this for a specific purpose? If you need to include mine .vimrcor .ycm_extra_conf.pyplease post in the comments. Also, if I need additional tools, please specify them so that I can customize them as well.

This is how I set up the kernel programming environment with vim.

Used tools:

  • OmniCompletion : built-in vim function (without additional plugins) for automatic completion
  • ctags : creates the code index database, which is necessary for OmniCompletion (and some other vim plugins)
  • cscope : a tool for code navigation (for example, you can go directly to the definition of the function under cursor, etc.). Creates its own code index database (other than ctags).

1. Install tools

First install vim, ctags and cscope:

$ sudo aptitude install vim vim-gtk cscope exuberant-ctags

2. Create an index database

cscope ctags. script ( ):

#!/bin/bash

list_sources() {
    echo "---> Listing sources..."

    find .                                   \
        -path "./arch*" -prune -o            \
        -path "./tmp*" -prune -o             \
        -path "./Documentation*" -prune -o   \
        -path "./scripts*" -prune -o         \
        -type f -name "*.[chsS]" -print >cscope.files

    find arch/arm/include/                   \
        arch/arm/kernel/                     \
        arch/arm/common/                     \
        arch/arm/boot/                       \
        arch/arm/lib/                        \
        arch/arm/mm/                         \
        arch/arm/mach-omap2/                 \
        arch/arm/plat-omap/                  \
        -type f -name "*.[chsS]" -print >>cscope.files
}

create_cscope_db() {
    echo "---> Creating cscope DB..."
    cscope -k -b -q
}

create_ctags_db() {
    echo "---> Creating CTags DB..."
    ctags -L cscope.files
}

cleanup() {
    echo "---> Removing garbage..."
    rm -f cscope.files
}

list_sources
create_cscope_db
create_ctags_db
cleanup

script ARM ( OMAP). (, x86), find script.

script , :

  • (cscope.files), find.

  • cscope ( cscope.files ) (. -k man cscope), :

    $ cscope -b -q -k

  • ctags (tags), cscope.files (. man ctags):

    $ ctags -L cscope.files
