libkms++ is a C++11 library for kernel mode setting.
-Also included are simple test tools for KMS and python wrapper for libkms++.
+Also included are some simple utilities for KMS and python bindings for libkms++.
-## Test tools
+## Utilities
+- testpat - set modes and planes and show test pattern on crtcs/planes
- kmsprint - print information about DRM objects
-- testpat - set modes and show test pattern on crtcs/planes
- 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
## Dependencies:
- libdrm
-- SWIG 3.x (for python bindings)
- Python 3.x (for python bindings)
## Build instructions:
+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
## Cross compiling instructions:
-Directions for cross compiling depend on your environment. These are for mine (buildroot):
+Directions for cross compiling depend on your environment.
-As above, but specify `-DCMAKE_TOOLCHAIN_FILE=<path>/your-toolchain.cmake` for cmake, where your-toolchain.cmake is something similar to:
