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.

Documentation is available on the website.

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 setup 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
