67 For Semantic Patch Language(SmPL) grammar documentation refer to:
72 ------------------------------------
74 A Coccinelle-specific target is defined in the top level
76 front-end in the ``scripts`` directory.
78 Four basic modes are defined: ``patch``, ``report``, ``context``, and
82 - ``patch`` proposes a fix, when possible.
84 - ``report`` generates a list in the following format:
85 file:line:column-column: message
87 - ``context`` highlights lines of interest and their context in a
88 diff-like style. Lines of interest are indicated with ``-``.
90 - ``org`` generates a report in the Org mode format of Emacs.
97 - ``chain`` tries the previous modes in the order above until one succeeds.
99 - ``rep+ctxt`` runs successively the report mode and the context mode.
106 To make a report for every semantic patch, run the following command::
112 make coccicheck MODE=patch
115 The coccicheck target applies every semantic patch available in the
116 sub-directories of ``scripts/coccinelle`` to the entire Linux kernel.
118 For each semantic patch, a commit message is proposed. It gives a
119 description of the problem being checked by the semantic patch, and
131 --------------------------
142 ``--chunksize 1`` argument. This ensures we keep feeding threads with work
151 Using Coccinelle with a single semantic patch
152 ---------------------------------------------
154 The optional make variable COCCI can be used to check a single
155 semantic patch. In that case, the variable must be initialized with
156 the name of the semantic patch to apply.
160 make coccicheck COCCI=<my_SP.cocci> MODE=patch
168 ---------------------------------------------------
173 For example, to check drivers/net/wireless/ one may write::
182 For example, to check drivers/bluetooth/bfusb.c, the value 1 is
183 passed to the C variable to check files that make considers
186 make C=1 CHECK=scripts/coccicheck drivers/bluetooth/bfusb.o
188 The value 2 is passed to the C variable to check files regardless of
191 make C=2 CHECK=scripts/coccicheck drivers/bluetooth/bfusb.o
196 This runs every semantic patch in scripts/coccinelle by default. The
198 semantic patch as shown in the previous section.
204 ---------------------------------
217 rm -f cocci.err
222 add both ``--profile --show-trying`` to SPFLAGS when debugging. For example
225 rm -f err.log
227 … make coccicheck DEBUG_FILE="err.log" MODE=report SPFLAGS="--profile --show-trying" M=./drivers/mfd
237 Currently, DEBUG_FILE support is only available to check folders, and
243 --------------------
249 - Your current user's home directory is processed first
250 - Your directory from which spatch is called is processed next
251 - The directory provided with the ``--dir`` option is processed last, if used
257 OPTIONS="--dir $srcroot $COCCIINCLUDE"
278 spatch --print-options-only
289 ----------------
295 make SPFLAGS=--use-glimpse coccicheck
299 is in the file .id-utils.index on the top level of the kernel. Coccinelle
302 mkid -i C --output .id-utils.index
307 make SPFLAGS=--use-idutils coccicheck
312 make SPFLAGS="--use-idutils /full-path/to/ID" coccicheck
314 See ``spatch --help`` to learn more about spatch options.
316 Note that the ``--use-glimpse`` and ``--use-idutils`` options
322 SmPL patch specific options
323 ---------------------------
326 to Coccinelle. SmPL patch-specific options can be provided by
327 providing them at the top of the SmPL patch, for instance::
329 // Options: --no-includes --include-headers
331 SmPL patch Coccinelle requirements

335 may require newer versions of Coccinelle. If an SmPL patch requires
