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]
