libkms++ is a C++11 library for kernel mode setting.

Also included are some simple utilities for KMS and python bindings for libkms++.

• testpat - set modes and planes and show test pattern on crtcs/planes
• kmsprint - print information about DRM objects
• kmsview - view raw images
• db - simple double-buffering test
• kmscube - rotating 3D cube on crtcs/planes
• kmscapture - show captured frames from a camera on screen

• libdrm
• Python 3.x (for python bindings)

To build the Python bindings you need to set up the git-submodule for pybind11:

git submodule update --init

And to compile:

$ mkdir build
$ cd build
$ cmake ..
$ make -j4

Directions for cross compiling depend on your environment.

These are for mine with buildroot:

$ mkdir build
$ cd build
$ cmake -DCMAKE_TOOLCHAIN_FILE=<buildrootpath>/output/host/usr/share/buildroot/toolchainfile.cmake ..
$ make -j4

You can use the following cmake flags to control the build. Use -DFLAG=VALUE to set them.

You can use the following runtime environmental variables to control the behavior of libkms.
