- 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.
- Changed the name of the entry point of the gui plugin code to
lib{gui_name}_gui_plugin_init(). It is used when loading plugin with the new
type. Added gui init code for the non-plugin version in plugin.cc.
- Some related changes for the "wx" case.
- The function load_and_init_display_lib() now only returns 1 on success.
- Minor other changes.
Prepared "biosdetect" option in the harddrv code.
TODO #1: Add support for a comma-separated list of BIOS options.
TODO #2: Implement support for at least "biosdetect=none" in the Bochs BIOS.
configuration, loading images). Cleaned up "romimage" option parsing and
prepared parameter "options" for the behaviour of the Bochs BIOS.
TODO: implement BIOS option "fastboot" to skip the boot menu prompt.
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.
- Create a file with image name plus extension ".lock" if an image is opened
in read/write mode. This file will be deleted after closing the image.
- Check for a lock file before opening an image and fail if it exists.
- Check for a lock file before creating a undoable/volatile redolog file and
fail if it exists.
- Only keep the comments for the specific gui methods in nogui.cc and add
references to this file in all other gui sources.
- Changed the order of methods and added some useful comments in gui.cc / gui.h.
- Minor other cleanups
- Removed unused functions and declarations.
- Removed unused command line argument handling.
- TODO: Modify the "plugin_init" and PLUGTYPE_* definitions.
- Added gui console support to the rfb and vncsrv guis.
- Started preparing the legacy SDL gui for console support.
- TODO: The sdl and sdl2 guis need a special keyboard handling for shifted keys.
- Moved helper function reverse_bitorder to the common gui code.
- In console_refresh() call flush() after text_update().
- Started preparing rfb, sdl, sdl2 and vncsrv gui for using the console.
- Some other small cleanups.
- vncserv.cc: Fixed sdl font issue.
- Don't check for mouse toggle event if console is active.
- Added support for blinking cursor.
- Added stubs in the gui code to reduce BX_USE_TEXTCONIG usage in x.cc.
code. Now the runtime configuration runs in the Bochs window instead of
console / xterm. The simulation screen is restored when the
simulation continues. This feature can be implemented for all guis
without gui dialog box support (e.g. sdl2/sdl2 on non-win32 platforms, rfb).
"fatal". It can be used for all cases when there is no workaroud present to
avoid application crash or incorrect simulation behaviour. As a first step now
using BX_FATAL() for some data structure size and bit field errors.
- Show message box (modified ask dialog) in method fatal() if not called after
ask dialog or pressing power button.
- Removed code for unsupported actions "ask" and "fatal" from info() method.
- Some related small code cleanups.
- Added new symbol BX_SYNC_EVT_LOG_DLG and method log_dlg() in siminterface to
handle the cases "ask", "warn" and "quit".
- Added support to change action from "warn" to "report in the "warn" dialog
(sdl2, win32 and wx).
- TODO: Add quit message box for the log action "fatal" and add BX_FATAL()
macro for all cases where continuing after BX_PANIC would be dangerous.
- Added new logfunctions method warn() similar to ask().
- Added new siminterface method log_warn() similar to log_ask().
- Modified sdl2, wx and win32 ask dialog to make it usable for warnings.
- On X11 use the new message box dialog to display warnings.
- Some related changes in the logio and siminterface code.
- Rewrite of the existing yes/no dialog to support more button options. Now it
can be used with OK/Cancel buttons or as a simple message box with OK or
Cancel. This message box that can be used to show error messages with a
new action "warn" or for critical panics when continuing would be dangerous
("BX_FATAL"). These features are not implemented yet.
- Partial rewrite of the button handling code (e.g. new method add_button()).
- some malloc/free to new/delete changes.
- The retry timer now calls process_transfer_ring() for enabled slots only.
- On USB3-only ports ignore device speed setup and try to enable super-speed mode.
- Added support for HID devices in high-speed mode.
- Added separate descriptors for MSD devices in high-speed mode.
- NOTE: USB 2.0 values ported from Qemu / tested with USB EHCI.
async mode by default for all USB devices (used by disk, cdrom and floppy).
Whenever we implement a new HC model, it is still possible to set the async mode
to 0 until the async packet completion is working correctly.
- Extended USB callback definition to support different event types sent from
device to HC. Currently we only have the two events "async completion" and
"remote wakeup".
- Implemented event handlers in the UHCI, OHCI and EHCI. For the EHCI version
we currently have no test case.
- The external USB hub now uses this feature at device connect/disconnect.
Now the device change on the hub is correctly detected by the guest OS.
- TODO #1: remote wakeup and async completion for the xHCI.
- TODO #2: event handler for the external hub to make a USB device work on
a chain of hubs.
- TODO #3: the event handler possibly could be used for the packet copy code.
- use get_dwords() and put_dwords() from EHCI sources for reading / writing
xHCI data structures as dword array. This fixes some endianness issues.
- simplified copying data from / to data structures since we can now use the
dword array with the correct byte order directly.
- fixed all remaining "strict-aliasing" GCC warnings.
configuration, get/set status, get descriptor) to the base class to reduce code
duplication. The device calls the common handle_control() method and then it
processes unhandled requests in it's specific code. (similar to Qemu).
- USB xHCI NAK handling fix by Ben. Now openSUSE 13.2 boots without hang with
hub connected to an xHCI port.
- Updated Ben's email address and year in some copyright headers.
- Get rid of device_buffer and use packet init / cleanup functions.
- Read immediate data from memory location instead of possibly byte-swapped
TRB parameter.
- Moved UHCI async packet functions to usb_common.h for using then on both
UHCI and OHCI.
- Modified OHCI packet handling based on the UHCI implementation.
- Renamed EHCI helper function to avoid conflicts.
- TODO: async packet support on xHCI.
- Added missing queue handling code for init, reset and device disconnect.
- Added EHCI status access methods for async and periodic state.
- Added a lot of comments (mostly from the original EHCI core code).
- UFI/CBI floppy: bus-powered, no remote wakeup
- HID (mouse, tablet, keypad): bus-powered, remote wakeup
- MSD (disk, cdrom), printer: self-powered, no remote wakeup
TODO: Remote wakeup is not yet implemented. A device should be able to resume
it's upstream port if suspended.
- HcLSThreshold is writable, but it's usually not modified (same as Qemu).
- BX_ERROR should only occur on an attempt to change the number of ports.
- Don't register read-only items for save/restore.
- Changed some device descriptor fields (using values from Qemu).
- Ported device reset code from Qemu.
- Check device speed setting on connect (only low/full speed supported yet).
- TODO: External hub doesn't work properly in some test cases (device change
not detected by guest OS, openSUSE 13.2 hangs with hub on xHCI).
- USB mouse and keypad now return NAK response when idle and there is no change.
- Implemented HID commands for get/set idle duration.
- Fixed NAK behaviour in UHCI and OHCI.
TODO list: USB tablet should also return NAK (doesn't work yet), review xHCI for
the NAK behaviour, accurate implementation of the idle duration
is currently supported per hub at the same time (same as OHCI).
TODO #1: We should support at least one async operation per connected device.
TODO #2: Async packet support for EHCI and xHCI.
- added a hack to make EHCI work in Bochs, but without asynchronous packet
support (tested with "high-speed" USB disk).
- added missing list for connected USB device state.
- fixed some of the endianness issues
- fixed some of the GCC warnings
- changed some BX_INFO to BX_DEBUG
- FIXME: non-bulk devices not yet working on xHCI. Linux guest hangs during boot
when HID or hub device is connected.
instead of the hub's remove_device() method. The external hub removes connected
devices before clearing it's own list. This fixes crash on exit when devices
are present on external hub.
ignores connected high speed device (fixes panic with EHCI on guest OS init or
shutdown). The other HC's now panic and disconnect device if the user decides
to continue.
Asynchronous transfers are not yet working properly (tested with USB disk device
in high speed mode). That's why the support for "speed:high" is still disabled.
Since we have no test case for the isosynchronous mode, I have not yet ported
the main code for it.
- 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.

- added method to change port ownership.
- fixed UHCI reset and initialized device pointers.
- added symbol UHCI_FULL_DEBUG to reduce debug output if not set.
- renamed connection handling method.
