Subject: Small patches for SDL/win32
I've tried playing with running SDL compiled for Windows with Wine (and
WineX) under Linux. It didn't originally work too well, but I somehow
managed to make it work. Most of the fixes was patches to Wine(X), but I
also found something in video/windx5/SDL_dx5video.c which, as far as I can
tell, actually is a bug in SDL. The result from the COM method Release,
which returns the new reference count, is compared to DD_OK. Because
QueryInterface is called immediately before, the reference count shouldn't
be DD_OK (== 0).

================================================================= Patch version 0.9 of SDL(Simple DirectMedia Layer) for Nano-X API ================================================================= Authors: Hsieh-Fu Tsai, clare@setabox.com Greg Haerr, greg@censoft.com This patch is against SDL version 1.2.4. It enhances previous patch 0.8 by providing direct framebuffer access as well as dynamic hardware pixel type support, not requiring a compile-time option setting for different framebuffer modes. Tested against Microwindows version 0.89pre9. Older Microwindows versions =========================== If running on a version older than Microwindows 0.89pre9, the following items might need to be patched in Microwindows. 1. Patch src/nanox/client.c::GrClose() It fixes the client side GrClose(). In the original version, GrOpen() can only be called once. When the GrOpen() is called at the second time, the program will terminate. In order to prevent this situation, we need to insert "nxSocket = -1" after "close(nxSocket)" in GrClose(). If you do not have this problem, you may skip this step. 2. Patch src/nanox/clientfb.c to return absolute x,y coordinates when using GrGetWindowFBInfo(). Copy the version 0.89pre9 of src/nanox/clientfb.c to your system, or configure using --disable-nanox-direct-fb. ============= Quick Install ============= 1. ./configure --disable-video-x11 --disable-video-fbcon \ --enable-video-nanox \ --with-nanox-pixel-type=[rgb/0888/888/565/555/332/pal] 2. make clean 3. make 4. make install (as root) ============ Nitty-gritty ============ --enable-nanox-direct-fb Use direct framebuffer access --enable-nanox-debug Show debug messages --enable-nanox-share-memory Use shared-memory to speed up When running multi-threaded applications using SDL, such as SMPEG, set THREADSAFE=Y in Microwindows' config file, to enable GrXXX() system call critical section support. ============================================= Some programs can be used to test this patch. ============================================= 1. http://www.cs.berkeley.edu/~weimer/atris (a tetris-like game) 2. http://www.libsdl.org/projects/newvox/ 3. http://www.libsdl.org/projects/xflame/ 4. http://www.libsdl.org/projects/optimum/ 5. http://www.gnugeneration.com/software/loop/ 6: http://www.lokigames.com/development/smpeg.php3 (SMPEG version 0.4.4) ========= Todo List ========= 1. Create hardware surface 2. Create YUVOverlay on hardware 3. Use OpenGL 4. Gamma correction 5. Hide/Change mouse pointer 6. Better window movement control with direct fb access 7. Palette handling in 8bpp could be improved ===================== Supporting Institutes ===================== Many thanks to go to Setabox Co., Ltd. and CML (Communication and Multimedia Laboratory, http://www.cmlab.csie.ntu.edu.tw/) in the Department of Computer Science and Information Engineering of National Taiwan University for supporting this porting project.
