- Changed variable type of the plugin_t "type" member from enum to Bit16u.
- Added support for returning device flags with the new mode PLUGIN_FLAGS in
the plugin entry functions. It is currently only used for devices that can
be connected to a PCI slot.
- Code cleanup in core device plugins: checking type no longer necessary.
- The "non-plugin" mode now also uses the "loadtype" member of plugin_t.
TODO: Change PCI slot options to bx_param_enum_c and build the choices list
using the new capabilities of the plugin API.
- Added special mode to all plugin entry functions that returns the plugin type.
- The plugins search function now temporarily loads all available plugins and
reads the plugin type using the new mode PLUGIN_PROBE.
- Added "loadtype" to the plugin structure to store the type used for plugin
loading (currently only the voodoo plugin provides two types).
module code. Sound driver names are now stored as string constants instead
of hardcoded values. Available modules are detected at Bochs startup and stored
in a string array before initializing options. In the plugins case available
modules are read from the plugins list. If plugins are off, the registry of
bx_sound_lowlevel_c is used. Related changes similar to the hdimage and
network modifications.
plugin_entry(). The additional boolean argument "init" is used to select the
requested action. The entry points still have unique names for compatibility
with the "non-plugin" compilation. Added macros for setting up these names
(e.g. PLUGIN_ENTRY_FOR_MODULE for device plugins).
- 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.
- Added INT pin init to method init_pci_conf().
- Moved readonly register handling to the common PCI write handler.
- Moved IRQ line reporting to the common PCI write handler.
- 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.
- 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.
- 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.
- added Android case to the configure script.
- renamed file memory.h to memory-bochs.h to fix conflict with NDK.
- fixed Android issues in some files.
- 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.
- Implemented wave output using the 'soundfile' driver including dual wave
output in wavemode 3. Removed now obsolete output file handling and other
cleanups. The wave input (recording) feature is not affected by the
wavemode setting.
- Moved VOC file handling to the soundfile code.
- Updated iodev makefile dependencies.
- Added the capability to load up to 4 sound drivers and added methods to
get pointers to the waveout, wavein and midiout services of a driver.
- Rewrite of the SB16 midi file output code. In midimode 2 and 3 the midiout
service of the 'file' driver is used. Removed obsolete midi file handling.
- Re-implemented the closemidioutput() method to make runtime changes of the
midi setup work with the new code.
creates the object and returns a pointer to it. TODO: The wavein and midiout
components should also move to separate classes. When finished, it should be
possible to configure the sound support more detailed (e.g. waveout with sdl,
midiout with alsa and the dummy driver for wavein). Creating a separate
module for the output to file(s) is also possible.
- Define new structure bx_pcm_param_t and use it as a parameter for the method
sendwavepacket(). The method startwavepacket() is now called from
sendwavepacket() in case of a parameter change (temporary solution).
- soundsdl: Replaced waveready() call by some more accurate code for buffer
space check in sendwavepacket().
- soundsdl: Moved code for reading from audio buffer to a new function.
- soundsdl: Temporarily increase the audio buffer size.
- Preparing the SB16 code for the OPL emulation port from DOSBox.
A device can set it with setTimerParam() and read it in the timer handled using
triggeredTimerParam(). Simplified some timer handler by using these methods.
TODO: implement HD / CD seek timer
usb device plugins. Loading the plugin means that the user wants to enable it.
Disabling the device on the command line and in the config interface is still
possible.
- ES1370: implemented CODEC registers (AK4531 mixer) and wave volume control
- Moved wave volume application code to new method pcm_apply_volume() and use
it for both soundcards
- TODO: stereo support
- es1370: fixed wave file parameter name
- wx cdrom dialog: use the first item of the cdrom runtime parameter list
- wx ParamDialog: always pause the simulation thread while setting parameters
- wx ParamDialog: call SIM->update_runtime_options() before continuing simulation
- SB16: log file name now also available as a runtime option
- SB16: changed order of the runtime options and minor other changes
- ES1370: changed the "wavemode" parameter type to bx_param_enum_c and set up
more accurate dependencies (similar to SB16)
- ES1370: wave mode and file name now available as a runtime option
- ALSA stuff moved from soundlnx.* to new soundalsa.* files
- SB16 / ES1370: including specific sound driver headers not necessary
- updated dependencies
