It has been compiled and tested on Linux, with MinGW/MSYS and MSVC nmake.
TODO: Check whether or not the config interface choice "win32config" can be
a plugin, too. Possibly add a new plugin type for config interfaces.
interface to textconfig if the selected gui has a builtin console in
SIM->set_init_done(). This is required on Windows for the rfb and vncsrv guis.
Cleaned up the textconfig code.
plugin is possible now. Added new functions text_print() and text_ask() in
textconfig.cc to replace related methods of bx_param_c classes. Removed a now
obsolete comment section in siminterface.h.
- Don't include paramtree.h in siminterface.h to get rid of duplicates
in a lot of Makefile dependency lines.
- Regenerated Makefile dependencies in iodev and affected subdirectories.
- FIXME #1: including debug.h causes duplicate entries of config.h and osdep.h.
- FIXME #2: cpudb.h appears in most of the iodev* dependencies, but only needed
by config.cc and the cpu class.
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.
- bx_load_plugin() now returns the status of the operation.
- Plugin load failures are now correctly handled by the plugin code (unloading
if necessary, then panic).
string constants instead of hardcoded values. Available modes are detected at
Bochs startup and stored in a string array before initializing options. In the
plugins case additional modes are read from the plugins list. If plugins are
off, the hdimage_locator_c registry is used. Related changes in all parts of
Bochs that need the hdimage stuff.
TODO #1: Network and sound drivers could be handled in a similar way.
TODO #2: Make disk image mode detection work again in plugins mode.
The latest release is from 2001 and it will not work on modern Linux systems.
Parts of the SVGALib code have been moved to the Linux kernel and the X11 and
SDL libraries are using it as a video driver.
Moved status bar update to the gui thread and added a new event type called
BX_ASYNC_EVT_STATUSBAR to invoke it. Changed size and style of the status bar
items.
This code is based on the initial patch by Ben Lunt with some modifications:
using enum parameter, extra parser handler and cdrom handling not necessary,
TODO: hdimage and bximage code, harddrv and USB disk emulation, BIOS.
- Added new PCI chipset choice for the i440BX AGPset. Some basic work is done,
but AGP support is not present yet.
- Added new class for the "virtual" PCI-to-PCI bridge that should manage the
secondary bus (AGP). Since this device must appear with device number #1 at
the primary bus, it was required to change the PCI device numbers for the
i440BX case. Moved the PIIX4 module to device number #7. The presence of the
PCI base address regions now depends on the header type as expected.
- Since the Bochs BIOS cannot handle the modified PCI device layout, all tests
continued with an external BIOS designed for this chipset (GA-6BA_F1.bin).
This BIOS requires additional changes in some devices.
- ACPI: Return value 0 for some status registers and the GPI registers.
- CMOS: Since the PIIX4 supports a 256 byte CMOS RAM, prepared support for it
and enable it in case a 256 byte CMOS image is used.
- PCI: The device numbers for 4 slots starting at #8. The 5th slot could be
used for AGP when available.
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.
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).
- 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.
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
gui init and string paramter handler. The shortcut keys are now stored in an
array of BX_KEY* values in the gui object.
siminterface.h: Fixed some default return values.
for watching the log output at simulation time. This feature has been prepared
and described in the code (BX_ASYNC_EVT_LOG_MSG), but it was never implemented.
A viewer window could be implemented easily in wx. The gui debugger could also
have an option to view the log output while debugging.
- in wx we had two logfunctions for the siminterface (removed duplicate init)
- renamed siminterface prefix to "SIM"
- moved variable "pluginlog" to the plugin interface
- fixed / removed some forward declarations
- added menu item for saving configuration
- use existing cdrom runtime menu instead of hardcoded items
- some code cleanups after cdrom option changes
- removed parameter "present" and use the new drive type "none" instead
- re-implemented cdrom media status parameter as a bx_param_enum_c
- TODO: change floppy media status parameter type to be consistent
- fixed bochsrc line after a "raw byte" string parameter
- changed parameter name "macaddr" to "mac" (same as bochsrc option parameter)
- skip disabled parameters when building the bochsrc line
- added "multiline" switch to select the output format (one or multiple lines)
- renamed siminterface method and use it in the network devices code
- renamed config parameter "i440fx_support" to "enabled"
- new config parameter "chipset" added (current choices "i430FX" and "i440FX")
- don't load ACPI support if the i430FX chipset is selected
- select register values for the core PCI devices depending on the chipset
- USB UHCI must be connected to a PCI slot if the i430FX chipset is used
- rombios changes to make the i430FX chipset work
- TODO #1: implement limitation to 1 cpu and 128 MB RAM for the i430FX chipset
- TODO #2: verify register behaviour of both chipsets
