# libdisplay-info
|
|
|
|
EDID and DisplayID library.
|
|
|
|
Goals:
|
|
|
|
- Provide a set of high-level, easy-to-use, opinionated functions as well as
|
|
low-level functions to access detailed information.
|
|
- Simplicity and correctness over performance and resource usage.
|
|
- Well-tested and fuzzed.
|
|
|
|
## Contributing
|
|
|
|
Open issues and merge requests on the [GitLab project].
|
|
|
|
In general, the [Wayland contribution guidelines] should be followed. In
|
|
particular, each commit must carry a Signed-off-by tag to denote that the
|
|
submitter adheres to the [Developer Certificate of Origin 1.1]. This project
|
|
follows the [freedesktop.org Contributor Covenant].
|
|
|
|
## Building
|
|
|
|
libdisplay-info is built using [Meson]. It has no dependencies.
|
|
|
|
meson build/
|
|
ninja -C build/
|
|
|
|
## Testing
|
|
|
|
The low-level EDID library is tested against [edid-decode]. `test/data/`
|
|
contains a small collection of EDID blobs and diffs between upstream
|
|
`edid-decode` and our `di-edid-decode` clone. Our CI ensures the diffs are
|
|
up-to-date. A patch should never make the diffs grow larger. To add a new EDID
|
|
blob or update a diff, use `test/edid-decode-diff.sh test/data/<edid>`.
|
|
|
|
## Fuzzing
|
|
|
|
To fuzz libdisplay-info with [AFL], the library needs to be instrumented:
|
|
|
|
CC=afl-gcc meson build/
|
|
ninja -C build/
|
|
afl-fuzz -i test/data/ -o afl/ build/di-edid-decode
