- Reworked wave callback code to support 2 input sources (no mixing yet).
- Fixed SDL sound output.
- Beep generator fixes.
- Prepared the SB16 code for FM OPL output support (to be ported from DOSBox).
- Renamed wavedata callback type.
- Handle sample rate in the beep generator (TODO: handle data format).
- Don't call waveready() in the SB16 code.
- Attempt to fix SDL2 wave output using SDL_LockAudio() / SDL_UnlockAudio().
- SDL specific code in the beep thread no longer needed.
- Added framework for polling wave data and use it for beep output in sdl.
- Some work in the beep thread code (to be continued).
- Moved macros required for multithreading to bochs.h.
- added new symbol BX_WITH_SDL2 and prepared build system
- TODO #1: add new option --with-sdl2 to configure script
- TODO #2: add new file sdl2.cc (porting seems hard to do - writing from scratch
might be better)
- added 'sound' option to select the driver and the wave output device
(see bochsrc sample for details)
- the wave device option of sb16 and es1370 is now only used to set up the
wave input device (if necessary)
- cleaned up the speaker code to initialize the 'sound' case correctly
