- Removed "pseudo device plugin" containing common code and specific drivers.
- Moved network module base classes and module handling to the Bochs core.
Now loading network driver plugins in netmod.cc.
- Moved shared networking code used by the 'vnet' driver and 'bxhub' from
netmod.cc/.h to new files netutil.cc/.h.
- Created separate plugins for each network driver implementation.
- Modified Bochs plugin system to support new plugin type PLUGTYPE_NETWORK.
external program 'bxhub' (simulating a two port ethernet hub). It is based on
an old SF patch and it has been updated and extended:
- Windows support (tested with MinGW/MSYS and MSVC nmake).
- Command line arguments for 'bxhub' (base port number, MAC address, TFTP).
- Added support for DHCP, TFTP, ARP and ICMP echo (ping). It uses parts of the
code for the 'vnet' module with some additions from the former "slirp backend".
- TODO: code cleanup to reduce duplication, rewrite of the networking plugins
stuff similar to the work done with the sound drivers.
- 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.
almost implemented, the port owner handling and the UHCI companion controllers
are present. High speed devices are not yet supported, since the EHCI scheduler
code has not been written yet (e.g. porting from Qemu). Low and full speed
devices should be detected correctly and work after port ownership change to
UHCI. 6 ports are available and the bochsrc syntax is similar to other HCs.
emulation and usb_uhci.cc implements the setup for the PIIX3 chipset and the
runtime device change code. The UHCI core is required for the EHCI emulation,
since there can be multiple "companion" controllers for USB 1.1 device handling.
by Ben Lunt. To connect a USB floppy you can use the 'floppy' device with the
path to the image separated with a colon. VVFAT is also supported.
FIXME: The device detection fails on some recent Linux distributions.
FIXME: Only 1.44M media format is currently supported.
TODO: Media change without disconnect is not implemented yet.
VS2013 nmake. In addition to this change in the Bochs code, the environment
variables for the command prompt need to be modified this way:
===
set INCLUDE=%ProgramFiles(x86)%\Microsoft SDKs\Windows\7.1A\Include;%INCLUDE%
set PATH=%ProgramFiles(x86)%\Microsoft SDKs\Windows\7.1A\Bin;%PATH%
set LIB=%ProgramFiles(x86)%\Microsoft SDKs\Windows\7.1A\Lib;%LIB%
set CL=/D_USING_V110_SDK71_;%CL%

implemented important CPU statistics which were used for Bochs CPU model performance analysis.
old statistics code from paging.cc and cpu.cc is replaced with new infrastructure.
In order to enale statitics collection in Bochs CPU:
- Enable statistics @ compilation time in cpu/cpustats.h
- Dump statistics periodically by adding -dumpstats N into Bochs command line
- embedding combined manifest makes BOCHS.EXE usable
- list of DLL plugins now depends on the pci and debugger options
- 'make clean' now removes the generated manifest files
- renamed variable for external rules
- documentation update
complete and usable with the BOCHS.EXE built with the IDE.
TODO #1: fix BOCHS.EXE built with nmake (manifest issue)
TODO #2: make the currently fixed DLL plugin list variable
rules can be built now (keyboard, pit, gameport, serial, vga, svga_cirrus,
hdimage, netmod, soundmod, usb_common). The generated DLLs are usable with the
BOCHS.EXE built with the IDE, but the nmake won't work at all yet.
(bx_hdimage.dll) can be built now. All plugins that require special rules
could be fixed for nmake in a similar way.
TODO: find a way to compile plugins with standard rules (GNU make uses bx_%.dll
in that case, but MSVC nmake doesn't support this syntax).
required an external binary and it couldn't be ported to Windows. Now the new
builtin and portable slirp support based on Qemu's implementation is almost
stable and all the 'vnet' DHCP and TFTP features have been ported to the new
slirp module.
TODO: rename all the "slirp_new" stuff to "slirp"
- added container_of() macro replacement
- fixed unresolved symbol in netmod.cc
- added MSVC-style structure packing pragmas
- check for the presence of min / max macros
- enabled slirp_new for MSVC in configure script
TODO list:
- check for more updates from Qemu
- fix lots of compiler warnings
- reduce code duplication with 'vnet' module (DHCP, TFTP, ARP)
- add separate config file for slirp to make it more flexible (using the
'script' parameter)
- update MSVC workspace files
- add SMB support on Linux
- remove slirp backend module after next Bochs release
is almost a port of the Qemu 1.1.2 implementation. It has been tested successfully
on Linux and Windows (MinGW/MSYS). The networking module is currently called
"slirp_new", since the "slirp" backend module still exists.
TODO list:
- MSVC support (requires container_of() macro replacement)
- apply fixes and improvements from recent Qemu releases
- use our TFTP implementation to reduce code duplication
- check if we can share ARP and DHCP support with "vnet"
- add SMB support on Linux
- finally remove the slirp backend module support
when we use -lwsock32, but don't include it's header if __CYGWIN__ is defined.
Moved DEVICE_LINK_OPTS to a separate variable instead of appending options to
GUI_LINK_OPTS.
- reverted changes in SVN revision 10985 (-DWIN32 now works again with Cygwin)
- don't link Bochs.exe or RFB gui with wsock32.dll in the Cygwin case
- the win32 gui doesn't need to be linked wsock32.dll at all
'all' and 'clean'), minor code changes
TODO: floppy / hard disk image creation, add to VS2008 workspace
TODO: finally remove the legacy utilities bximage and bxcommit
- ALSA driver is now default on Linux (if present)
- SDL sound driver is now default if no platform-specific driver is available
and the SDL gui is enabled
- soundlnx.cc: sendwavepacket() now exits with error if device is not opened
- soundmod.cc: exit beep loop if sendwavepacket() returns error
- ALSA stuff moved from soundlnx.* to new soundalsa.* files
- SB16 / ES1370: including specific sound driver headers not necessary
- updated dependencies
- use the CXXFLAGS and link options provided by the libvncserver-config script
- added Windows support for MinGW/MSYS (compiles fine, but crashes sometimes)
higher resolutions and > 8 bpp graphics modes. The RFB gui with limited
capabilities is still available.
TODO:
- fix random segfaults in dimension_update()
- Windows (MinGW) support
- fixes for clients not supporting 'rfbEncodingNewFBSize'
- fix cursor shape after dimension update()
- scroll window has 16 visible items and the virtual size is not limited
- CPUID parameter list now using this feature
- FIXME #1: scroll window is not resized if browse button column is present
- FIXME #2: only one scroll window per dialog is supported
- PCI slot configuration, memory and i/o BAR registration, PCI i/o space
handlers now present in devices.cc
- configure: E1000 emulation and USB support need PCI
- vga: fixes for the non-PCI case
I am copiling using Cygwin+mingw and cnfigure script by default doesn't find and GUI library and therefore I supply --with-win32.
But seems it is not enough to get GUI debugger compiled - Makefile was missing win32_enh_dbg_osdep.cc
is based on a patch originally designed for DOSBox. Currently only the Voodoo1
adapter model can be emulation. The emulation is currently slow, but we intend
to clean up and optimize the code. Running the 3D engine in a separate thread
is also planned. To compile with Voodoo support the configure option
"--enable-voodoo" must be used. Then the device can be activated with
"plugin_ctrl: voodoo=1" in bochsrc or on the command line. The device will be
assigned automatically to a PCI slot unless you do that manually. A specific bochsrc
option to select the adapter model will be added when the code has support for it.
