# Contributing to dtc or libfdt
|
||
|
|
|
||
|
|
There are two ways to submit changes for dtc or libfdt:
|
||
|
|
|
||
|
|
* Post patches directly to the the
|
||
|
|
[devicetree-compiler](mailto:devicetree-compiler@vger.kernel.org)
|
||
|
|
mailing list.
|
||
|
|
* Submit pull requests via
|
||
|
|
[Github](https://github.com/dgibson/dtc/pulls)
|
||
|
|
|
||
|
|
## Adding a new function to libfdt.h
|
||
|
|
|
||
|
|
The shared library uses `libfdt/version.lds` to list the exported
|
||
|
|
functions, so add your new function there. Check that your function
|
||
|
|
works with pylibfdt. If it cannot be supported, put the declaration in
|
||
|
|
`libfdt.h` behind `#ifndef SWIG` so that swig ignores it.
|
||
|
|
|
||
|
|
## Tests
|
||
|
|
|
||
|
|
Test files are kept in the `tests/` directory. Use `make check` to build and run
|
||
|
|
all tests.
|
||
|
|
|
||
|
|
If you want to adjust a test file, be aware that `tree_tree1.dts` is compiled
|
||
|
|
and checked against a binary tree from assembler macros in `trees.S`. So
|
||
|
|
if you change that file you must change `tree.S` also.
