- 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.
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.
- 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.
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.
- 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.
- 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.
- 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.
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.
- 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.
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.
- 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.
- 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.
- 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.
