-q | --quiet | quiet |
-v | --verbose | verbose mode |
| | --no-tree | run without a kernel tree |
| | --no-signoff | do not check for the Signed-off-by line |
| | --patch | treat FILE as patchfile. Since this options is the default option, it needs not be explicitly specified. |
| | --emacs | emacs compile window format |
| | --terse | one line per report |
| | --showfile | emit diffed file position, not input file position |
-g | --git | treat FILE as a single commit or git revision range (single commit: <rev>, <rev>^ or <rev>~n, multiple commits: <rev1>..<rev2>, <rev1>...<rev2> or <rev>-<count>). Git mergesa are ignored. |
-f | --file | treat FILE as regular source file. This option must be used when running checkpatch on source files in the kernel. |
| | --subjective, --strict | enable stricter tests. By default the tests emitted as CHECK do not activate by default. Use this flag to activate the CHECK tests. |
| | --list-types | Every message emitted by checkpatch has an associated type. With this option list the possible message types are listed (and FILE is not read). Compare with --types and --ignore |
| | --types TYPE(,TYPE2…) | show only these comma separated message types. Compare with --list-types and --ignore |
| | --ignore TYPE(,TYPE2…) | ignore various comma separated message types. Compare with --list-types and --types |
| | --show-types | show the specific message type in the output. Compare with --list-types etc. |
| | --max-line-length=n | set the maximum line length, (default $max_line_length) if exceeded, warn on patches requires --strict for use with --file |
| | --min-conf-desc-length=n | set the min description length, if shorter, warn |
| | --tab-size=n | set the number of spaces for tab (default $tabsize) |
| | --root=PATH | PATH to the kernel tree root. This option must be specified if invoking checkpatch.pl from outside the kernel root. |
| | --no-summary | suppress the per-file summary |
| | --mailback | only produce a report in case of warnings/errors |
| | --summary-file | include the filename in summary |
| | --debug KEY=[0|1] | turn on/off debugging of KEY where KEY is one of values, possible, type and att' (default is all off) |
| | --test-only=WORD | report only warnings/errors containing WORD literally |
| | --fix | Experimental: tries to correct correctable errors to the preferred checkpatch style and writes FILE.EXPERIMENTAL-checkpatch-fixes. May create horrible results If correctable single-line errors exist |
| | --fix-inplace | Experimental - may create horrible results Is the same as --fix, but overwrites the input file. It's your fault if there's no backup or git |
| | --ignore-perl-version | Override checking of perl version. Expect runtime errors. |
| | --codespell | Use the codespell dictionary for spelling/typos (default:$codespellfile) |
| | --codespellfile | Use this codespell dictionary |
| | --typedefsfile | Read additional types from this file |
| | --color[=WHEN] | Use colors 'always', 'never', or only when output is a terminal ('auto'). Default is 'auto'. |
| | --kconfig-prefix=WORD | use WORD as a prefix for Kconfig symbols (default ${CONFIG_}) |
