weston gdlbackend is available on gitorious now

[Juan Zhao]

  Hi All,

     I've successfully run weston and its shm and egl/gles client over 
Intel CE platform SDV now. The screen-shot is like this:
wayland screenshot
     The code can be accessed on 
https://gitorious.org/wayland-and-weston-with-gdlbackend . The main code 
is just compositor-gdl.c, a gdl backend for weston. and this file is 
licensed as BSD.
     For the trying, you need to clone the weston TVgdl branch. And the 
driver should support gbm and wl_egl interfaces.

     Here are some info about weston gdlbackend:

running
#cd $WLD/bin
#./weston or ./weston --mode=720p

#cd WaylandSourceCode/client/
#./simple-shm or others


supporting modes
{ name, width,height, refresh, interlace }
{ "480i", 720, 480, GDL_REFRESH_59_94, GDL_TRUE },
{ "480p", 720, 480, GDL_REFRESH_59_94, GDL_FALSE },
{ "576i", 720, 576, GDL_REFRESH_50, GDL_TRUE },
{ "576p", 720, 576, GDL_REFRESH_50, GDL_FALSE },
{ "720p", 1280, 720, GDL_REFRESH_59_94, GDL_FALSE },
{ "720p50", 1280, 720, GDL_REFRESH_50, GDL_FALSE },
{ "1080i", 1920, 1080, GDL_REFRESH_59_94, GDL_TRUE },
{ "1080i50",1920, 1080, GDL_REFRESH_50, GDL_TRUE },
{ "1080p", 1920, 1080, GDL_REFRESH_59_94, GDL_FALSE },
{ "1080p50",1920, 1080, GDL_REFRESH_50, GDL_FALSE },
{ "1080p24",1920, 1080, GDL_REFRESH_23_98, GDL_FALSE },
{ NULL, 0, 0, 0, 0 }

*note:* 1080x is not supported now, because we are using cairo-image, 
and we will meet cairo SSE2 segment fault error when the mode is higher 
than 720p


summarize

method

Render to

	

Render to gbm buffer object and copy to gdl surface

	

Render to eglsurface which is on screen directly

modify the code to choose one method:

Enable FBO+GBM

	

#define GDL_USEFBO 1
#define TEST_GBM 1

Enable Render to Surface

	

#undef GDL_USEFBO
#undef TEST_GBM

Enable Performance Calc

	

#define PERFORMANCE_TEST 1


Thanks,
