Introduction
X11 Extensions:
x-composite : This extension should support redirecting of egl Surfaces to x11 pixmaps too.
+x-damage : This extension is required to render surfaces only, if there content has changed.
GLX / OpenGL :
Furthermore it should be supported to create an texture from an x11 pixmap.
-Beagle board platform
-===
-
-If you have choosen the BeagleRenderer as rendering backend, than the following
-kernel module must be available too :
-
-CMEM Module is needed, it can be downloaded from
-
-http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/linuxutils/index.html
-
-The EGL implementation on the beagle board should support the following egl config:
-
-EGL_SURFACE_TYPE = EGL_WINDOW_BIT | EGL_PIXMAP_BIT
-EGL_RENDERABLE_TYPE = EGL_OPENGL_ES2_BIT,
-EGL_RED_SIZE = 8
-EGL_ALPHA_SIZE = 8
-EGL_BIND_TO_TEXTURE_RGBA = EGL_TRUE
-
-Furthermore the application which should be rendered by the layermanagement, should initialize egl
-by the following steps:
-
-1. Get EGL Display
-2. Initialize EGL
-3. Bind API
-4. Choose EGL Config
-5. Allocate native pixmap Structure
-6. Allocate native pixmap space by CMEM_alloc
-7. Get physical address of native pixmap using the CMEM module, and assign the address to the native pixmap structure.
-8. Create egl pixmap surface using the allocated native pixmap.
-9. Create egl context.
-10. Make egl context with the surface as current.

+Change the Environment during Runtime
+=====================================
+The following environments can be set to change the runtime behaviour.
+
+LM_PLUGIN_PATH set the path for the location of communicator and renderer PlugIns
+ default : /usr/lib/layermanager
+ Example : export LM_PLUGIN_PATH= /usr/local/lib/layermanager
+
+LM_USE_SESSION_BUS enables the DBUS communication to run on Session bus instead of Systembus
+ default : disabled run on system bus
+ Example : export LM_USE_SESSION_BUS=enable
+
+Commandline parameter :
+LayerManagerService : -w<horizontalresolution> - default 1280
+ -h<verticalresolution> - default 480
+ -c<console debug level> - default 2 (only errors and info)
+ -f<file debug level> - default 0 (disabled) log file location is /tmp/LayerManagerService.log
+ possible debug levels : 0 disabled
+ 1 errors
+ 2 info,errors
+ 3 info,errors, warnings
+ 4 info,errors, warnings,debug
+ -v shows version of layermanager
+
+Running Testapplications
+=====================================
+
+1. Starting the service
+
+precondition :
+
+install prefix is /usr/local
+no compositing manager is running like openbox xfce metacity, kill these if needed
+
+run:
+#> export DISPLAY=:0
+#> export LD_LIBRARY_PATH=/usr/local/lib:/usr/lib
+#> export LM_PLUGIN_PATH=/usr/local/lib/layermanager
+#> LayerManagerService &
+
+2. Running OpenGL / OpenGL ES 2.0 Example Applications
+
+precondition :
+
+install prefix is /usr/local
+LayerManagerService Running
+
+run:
+#> export DISPLAY=:0
+#> export LD_LIBRARY_PATH=/usr/local/lib:/usr/lib
+OpenGL ES Example
+#> EGLX11ApplicationExample &
+OpenGL Example
+#> GLX11ApplicationExample &
+
+3. Running LayerManagerControl
+
+The LayerManagerControl can be used to change and debug
+the runtime behaviour of the service.
+
+Please Call :
+LayerManagerControl without arguments to see a list of supported commands
+
+Examples
+ LayerManagerControl get scene
+ LayerManagerControl get layers
+ LayerManagerControl get layer 1000
+ LayerManagerControl get surfaces
+ LayerManagerControl get surface 0xa
+ LayerManagerControl analyze surface 10
+ LayerManagerControl scatter
+ LayerManagerControl watch surface 0xa
+
+precondition :
+
+install prefix is /usr/local
+LayerManagerService Running
+
+run:
+#> export DISPLAY=:0
+#> export LD_LIBRARY_PATH=/usr/local/lib:/usr/lib
+#> LayerManagerControl [command]
