drm_info

Small utility to dump info about DRM devices.

Requires libdrm and json-c.

Building

Build with

meson build
cd build
ninja
sudo ninja install

If you don't have the minimum json-c version (0.13.0), meson will automatically download and compile it for you. If you don't want this, run the first meson command with

meson build --wrap-mode nofallback

Usage

drm_info [-j] [--] [path]...

• -j - Output info in JSON. Otherwise the output is pretty-printed.
• path - Zero or more paths to a DRM device to print info about, e.g. /dev/dri/card0. If no paths are given, all devices found in /dev/dri/card* are printed.
