Date: Tue, 4 Mar 2003 15:05:31 -0800 From: "Jim" Subject: [SDL] Frame Buffer patches... Okay I'm new at patch generation - so please tell me if there's a better way I could have done this. Attached are two patch files generated with 'cvs diff -u' SDL-fb-open-lock.patch applies to SDL_fbvideo.c Modifies the open loop to check /dev/fb/0 found on devfs... Modifies the lock code to return failure if the current virtual terminal is not the one opened for frame buffer writing... Lock would hang forever if switched away (ctrl-alt-F1) ... SDL-fb-mousedrv-screensave.patch applies to SDL_fbevents.c Switches default mouse mode based on SDL_MOUSEDRV - currently only accepts PS2 - otherwise default is MS Mouse. When the screen is switched - exisiting code (wrapped in ifdef SAVE_SCREEN_COTENTS) would save the wrong bit of the screen.... ( I run frame buffer 1600x1200, the size I requested was 800x600 - the save would save the top 800 lines (non biased) and restore them... Adding screen->offset fixed that ) However, if that option is not set, then a call to SDL_UpdateRect (full screen) is made. (which may have had it's contents changed since the screen is not entirely locked because of lock-failure patch) Jim [patches slightly tweaked for SDL 1.2.10]

This is the porting of 1.2.0 version of SDL (the latest stable one)
to AmigaOS/68k.

All the bugs known of the past version have been corrected. And I've
added all the new SDL features.

This version of SDL needs Cybergraphx V3 (r69+) or CyberGraphX V4
and AHI v3+. Probably it works also with P96 or CGXAga, but it's 
untested.

This version is available as linked library for SAS/C and GCC, only 68k this 
time, a powerup (ppcemu compatible) and a morphos version will be ready quite 
soon (i hope).

Implemented:

- 8/16/24/32bit video modes, both fullscreen and windowed.
- Hardware surfaces.
- CGX blitting acceleration.
- CGX colorkey blitting acceleration.
- AHI audio (8/16 bit, with any audio format), always uses unit 0 for now.
- Thread support (maybe not 100% compatible with other implementations)
- Semaphores 
- Window resizing and backdrop windows (NEW)
- Joystick/Joypad support.

To do:

- CDRom audio playing support
- OpenGL (A guy was working on it but I've lost his tracks :( )

The SAS/C library is distributed with debug info attached, to strip debug info 
simply add STRIPDEBUG argument to the linker.

NOTE: SDL includes debug output using kprintf, to disable it add to your 
project a function like this:

void kprintf(char *a,...)
{
}

Otherwise you can redirect the debug to a console window with sushi, sashimi or
similar tools (the default output is the internal serial port). 

For info, support, bugfix and other feel free to mail me:
