8952c144bd Some work on the i440BX chipset and related changes.
- Fixed PCI BAR initialization (now using memset()).
  - Fixed reset failure (set all PAM memory types to ROM).
  - Added stub for the AGP aperture (register BAR #0, handle APSIZE and read
    GART entry in read/write handlers).
  - Added some more PCI register defaults and write masks.
  - Fixed a warning in the ES1370 code.
  - Voodoo Banshee: set up PCI subsystem ID depending on bus and model.
  - Volatile BIOS write support must also be present in ISA BIOS memory.

87145baf61 Rewrite of the PCI base address (BAR) handling to reduce code duplication.
- Added new structure bx_pci_bar_t that contains all parameters related to the
  PCI BARs (type, size, address and r/w handlers).
- Added new methods init_bar_io() and init_bar_mem() to set up the new structure
  in the pci device init code.
- Added new method pci_write_handler_common() to handle writes to the normal
  BARs and the ROM BAR. Writes to other registers are forwarded to the device
  specific PCI write handlers. Removed BAR and ROM BAR handling from the
  specific code.
- Added new method pci_bar_change_notify() to execute specific code after BAR
  update (vga, ne2k).
- Moved normal BAR handling to method after_restore_pci_state().
- Store pointer to PCI device name in bx_pci_device_c and use it for i/o setup.

93b51df2cb Including stdint.h is not required here, since we are using Bit8u, Bit16u etc,
(thanks to Ben Lunt).

bdd8875692 Reverted BX_THREAD_KILL() changes in the lowlevel sound code. Now using control
variables again to let the threads end normally. Re-implenented the method
closewaveoutput() for some modules, move the destructor code to it and call it
after leaving the mixer thread. This fixes a deadlock in the "soundwin" module
if Bochs is compiled with plugin support.

5db2596317 The resampler and mixer threads are now stopped with BX_THREAD_KILL(). 2017-05-21 15:08:20 +00:00

c160fd4830 Bochs thread handling improvements:
- Modified win32 thread macros to use the handle instead of the id.
- Added new macro BX_THREAD_KILL to terminate threads.
Voodoo thread changes:
- Let the cmdfifo_thread sleep while the CMDFIFO is disabled.
- Kill the cmdfifo_thread in destructor and removed old thread control code.

c897ffa619 Cleanups in the Bochs system timer code
- Now using macro DEV_register_timer() in all devices and lowlevel modules.
- Removed unused timer stuff from the plugin.cc/.h code.

76b54ecb61 Renamed bx_pci_device_stub_c to bx_pci_device_c and derive it now from class
bx_devmodel_c. The early version of the combined vga / svga_cirrus code
required the now obsolete implementation. Some related cleanups in the
devices code.

d46a9b7205 Some work on the PCI devices code.
- Since the pci_read_handler() method is identical in most devices, move it
  to the base class to reduce code duplication. Only the 'pcidev' device has
  it's own implementation (NOTE: it is not maintained yet).
- Minor other fixes and cleanups in some PCI devices.

df6adaaf1f Added symbol VSIDE in the MSVC workspace files and and the manifest section
of win32res.rc to compile Bochs correctly with both IDE and nmake.
Fixed MSVC warnings in some devices.

29e9b54cfd Added dummy waveout class to make sure that resampling and mixing features
are not used. It also fixes a possible crash in the speaker code.

eeec43d811 Implemented self-registering static objects in the lowlevel sound code similar
to the network module handling. Now the 'dummy' sound driver can be a real
plugin, too.

0456c1034f Rewrite of the "no-plugins" code for loading/unloading gui, optional and sound
plugins. Now the plugin type is stored in the structure, so we need only one
array and one load function for plugins of these types.

Volker Ruppert
449c8ae620 Some more fixes in the new sound plugins code.
- Builtin sound driver plugin support should depend on BX_SUPPORT_SOUNDLOW.
- Added some symbols required for the MSVC plugin of sound driver "file".
- Clean up threads and audio buffers only when shutting down the primary sound
  driver (pcm_callback_id >= 0). Fixes crash on exit with wavemode 3.

60d24943c6 Rewrite of the sound driver plugin code.
- Renamed OSS sound driver files from soundlnx.cc/.h to soundoss.cc/.h.
- Removed "pseudo device plugin" containing common code and specific drivers.
- Moved common sound code, base classes of sound drivers and the dummy driver
  to the Bochs core. Now loading sound driver plugins in soundmod.cc.
- Created separate plugins for the platform/library specific drivers and the
  "file" driver.
- Modified Bochs plugin system to support now plugin type PLUGTYPE_SOUND.

f971dccddb Implemented SDL2 "wavein" service (Audio capture support is new in SDL 2.0.5
and does not yet work on all platforms).

f844e846b7 Added PCM output data resampling in a separate thread. The resampler requires
either libsamplerate or the SoX resampler library installed. If not installed,
the data is only copied to the output buffer and sample rate of the output
driver is changed similar to legacy code. Related changes:
- Added check for libsamplerate or SoX resampler header files in configure
  script.
- Added functions for converting source format to float (requied by resampler)
  and float to output format.
- Added support for float type data in the audio buffer code. Buffer chain #0
  receives float data from sendwavepacket() and buffer #1 receives data for
  mixing and output in format "16-bit signed little endian stereo".
- ALSA: Disable builtin resampling feature if resampler is present to avoid
  doing it twice.

1ac159ba52 Modified sleep rate in conversion thread to get more continuous output. 2015-08-18 17:26:25 +00:00
Volker Ruppert
ee6bfaa4c4 Added separate thread for the PCM data conversion. Only in case of dual output
sendwavepacket() directly calls the conversion method and output(). In all other
cases it puts the unmodified data into a buffer and the conversion thread is
doing the main job and puts the data into the output buffer chain.
TODO: resampling could also be done by the new thread.

377d920956 Created a new class for the audio buffer handling to make multiple buffers

fd690a3a31 Fixed compilation errors found on Cygwin64
- The 'Bits' type used in the opl files is incompatible with Bit64s. Modified
  typedef to fix this issue.
- On Windows use Sleep() directly, since msleep() doesn't exist in Cygwin.

a32bc18d9e Renamed SB16 parameters "midi" to "midifile" and "wave" to "wavefile" (same
as ES1370). Legacy parameter names are still supported.

92f48fa92f Implemented MIDI output support for the ES1370 soundcard. Data written to the
UART data port is sent to file or device similar to the SB16.

d8ca04c79f The current frame count registers are readable as word (not mentioned in specs).

a52bcdfa88 Minor fixes and cleanups in the SB16 code (no functional changes).
- the "remaplist" has 256 entries, but the limit was too high (4096).
- the "patchtable" had 4096 entries, but the index was never > 15.
- removed disabled / outdated code.

a256414d32 Some work on the ES1370 emulation.
- Undocumented "legacy" register at offset 0x1b is used to probe for the ES1370
  interrupt by the Win9x driver. Using bit #0 to control the IRQ line fixes
  driver installation.
- Added more detailed BX_ERROR messages for the UART registers.
- Small code cleanup in the write handler.
- TODO: fix possible bluescreen in Win98 guest after wave playback.

72cbbe9e8b Fixed incorrect calls of virtual functions in constructor/destructor.
- Removed useless set_pcm_params() call in base class contructor.
- SDL waveout destructor needs to call the unregister_wave_callback() method
  of the SDL stuff, since the base class destructor doesn't do that.
2015-03-29 15:53:56 +00:00
