kms++ - C++ library for kernel mode setting

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

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

Utilities

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

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.

Option name	Values	Default
CMAKE_BUILD_TYPE	Release/Debug	Release
BUILD_SHARED_LIBS	ON/OFF	OFF
KMSXX_ENABLE_PYTHON	ON/OFF	ON
KMSXX_ENABLE_KMSCUBE	ON/OFF	OFF

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

Variable	Description
KMSXX_DISABLE_UNIVERSAL_PLANES	Set to disable the use of universal planes
KMSXX_DISABLE_ATOMIC	Set to disable the use of atomic modesetting
