Modify framebuffer and NGA framebuffer to read screen size from board model dtb file. Optimise memory usuage of frame buffer
Add example minigui application with hooks to profiler (which writes results to S:\). Modified NGA framebuffer to run its own dfc queue at high priority
========================
Using SDL with PicoGUI
========================
- Originally contributed by Micah Dowty <micahjd@users.sourceforge.net>
PicoGUI is a scalable GUI system with a unique architecture, primarily focused
on scalability to various embedded systems. You can find more information
including a FAQ at http://picogui.org
To use the patch:
1. When compiling, add the "--enable-video-picogui" switch to ./configure
2. When running your program, ensure that the picogui driver for SDL
is in use by setting the SDL_VIDEODRIVER environment variable
to "picogui".
3. The program must also be linked to the C client library for PicoGUI
(libpgui.so). If the program is being compiled with a patched SDL
installed this should be done automatically. If you want to use an
existing binary with PicoGUI, you can set the LD_PRELOAD environment
variable to the path of your libpgui.so file.
Capabilities:
So far only basic functionality is provided on true color (linear16/24/32)
devices. Accessing a memory mapped bitmap, updating the display, and handling
mouse/keyboard input. This functionality has been tested with several
applications, including mplayer, Xine, sldroids, and Abuse.
TODO list:
- YUV overlays will be helpful for watching video on set top boxes or other
embedded devices that have some graphics acceleration hardware
- Account for rotated bitmap storage in pgserver
- Support for hiding or changing the cursor
- The display should be centered when the SDL application is smaller
than the PicoGUI panel
- Fullscreen or any other special modes
- Support for indexed and grayscale modes
- Probably much more...
