Some devices already had one. Some I had to add an empty one.
I did a little cleaning of init() methods to make them more uniform
but generally I left them alone.
- I also put these exact diffs into a patch "patch.iodev-add-reset"
in case I want to revert these changes for some reason, for example
if they break an old patch. It should be deleted after a while.
I use setjmp() to save the context just before calling
bx_continue_after_config_interface(). Then, in
bx_real_sim_c:quit_sim, I use longjmp() to jump back to that context.
This happens in main.cc and in gui/wxmain.cc (wxWindows only).
I haven't tested with the debugger yet. Possibly with debugger
the quit longjmp() should jump back to the debugger prompt loop
instead of actually quitting the program.
- clean up BX_ASYNC_EVT_LOG_MSG implementation by creating a different,
synchronous event called BX_SYNC_EVT_LOG_ASK. The async event
could be used to simply tell the CI that an event has occurred,
for example if the user wanted to view the events on screen
(not implemented). The sync event is used when you want the user
to respond before the simulation can continue, such as a for the
"panic=ask" behavior.
- in wxmain.cc, move the updates to the Start,Stop,Pause,Resume menu
items into a separate method simStatusChanged(). This makes the code that
does important stuff more readable.
- remove wxMutexGuiEnter()/Leave() from MyFrame::OnSim2CuiEvent().
This method is an event handler called in the gui thread, so it
already has the gui lock. This call caused thread lock on my linux
box.
again. This means that the simulation needs to stop in a consistent state,
including the "reentry check" variables in logfunctions::fatal() and
logfunctions::ask().
- fatal() is supposed to quit the simulation. add a clear panic message if it
doesn't quit, but remove the reentry check. The reentry check was causing
problems when you stop and start the simulation again.
- in ask(), keep the reentry check but set in_ask_already=0 before
calling fatal() so that ask() works if we start the simulation again.
and complain if fatal() fails to die.
bx_do_text_config_interface() to make it clear that it's not used
with wxWindows. Before, it was around only the line of that function that
failed to compile.
the terminology a bit. In particular, the term "gui" has started
to mean different things in different contexts, so I've defined
some more specific names for the parts of the user interface, and
updated comments and some variable names to reflect it. See
siminterface.h for a more complete description of all of these.
VGAW: VGA display window and toolbar buttons, the traditional Bochs
display which is ported to X, win32, MacOS X, etc. Implemented
in gui/gui.* and platform dependent gui/*.cc files.
CI: configuration interface that lets the user change settings such
as floppy disk image, ne2k settings, log options. The CI consists
of two parts: configuration user interface (CUI) which does the
actual rendering to the screen and handles key/mouse/menu events,
and the siminterface object.
CUI: configuration user interface. This handles the user interactions
that allow the user to configure Bochs. To actually change any
values it talks to the siminterface object. One implementation of
the CUI is the text-mode menus in gui/control.cc. Another
implementation is (will be) the wxWindows menus and dialogs in
gui/wxmain.cc.
siminterface: the glue between the CUI and the simulation code,
accessible throughout the code by the global variable
bx_simulator_interface_c *SIM;
Among other things, siminterface methods allow the simulator to ask the
CUI to display things or ask for user input, and allows the CUI
to query and modify variables in the simulation code.
GUI: Literally, "graphical user interface". Until the configuration menus
and wxWindows came along, everyone understood that "gui" referred to the
VGA display window and the toolbar buttons because that's all there
was. Now that we have the wxWindows code, which implements both the VGAW
and the CUI, while all other platforms implement only the VGAW, it's not
so clear. So, I'm trying to use VGAW, CI, and CUI consistently since
they are more specific.
control panel: This has been used as another name for the configuration
interface. "control panel" is also somewhat unspecific and it sounds
like it would be graphical with buttons and sliders, but our text-mode
thing is not graphical at all. I've replaced "control panel" with
"configuration interface" wherever I could find it. In configure script,
the --disable-control-panel option is still supported, but it politely
suggests that you use --disable-config-interface instead.
- clean up comments in siminterface,wx* code
- add comments and examples for bx_param_* and BxEvents
- remove some obsolete stuff: notify_*_args,
bx_simulator_interface_c::[sg]et_enabled() methods
- in siminterface.cc, move a few bx_real_sim_c methods to where they belong,
with the rest of the methods. No changes to the actual methods.
- remove some DOS ^M's which crept in and confused my editor.
mirrored the use of enable_control_panel exactly. This should not cause
any change in behavior, and it lets me eliminate these methods which
don't make much sense anymore.
- loading default bochsrc for the wx gui no longer necessary
- the wx gui version of bochs now accepts the same command line arguments as
the other guis
to "*_ENABLED"
- bx_serial_options for all 4 ports moved into an array com[4]
- serial port com1 is enabled by default
- detection of com2, com3 and com4 config options disabled for now
- new parameter "enabled" added to the serial bochsrc options
- error handling for serial and parallel bochsrc options changed. The unhandled
BX_PANICs are replaced by BX_ERRORs.
- new function bx_write_serial_options() added
- serial destructor restores original terminal settings only when serial port
is enabled and the tty_id is valid
parport1 with the new option "enabled". The old option "enable" only
controlled the output. The parport1 is enabled with no output by default.
Changes:
* bochrc option "enable" replaced by "enabled"
* parport option "Oenable" replaced by "Opresent"
* bx_parport_options par1 and par2 replaced by an array par[2]
* initialize parport1 resources only when enabled
* renamed variable "parport_init_list" to "par_ser_init_list" since it
contains parport and serial options
* documentation and bochsrc updates
- the parport variables "output" and "initmode" now belong to the bx_par_t
structure
- TODO: add parport2 (disabled by default), parport detection in the bios
installation dependent values in a global configuration file. If you are
including such a file, you only need to define the disk images and other
guest OS dependent stuff.
- new command line option '-q' (quickstart) added (the same as '-nocp')
- new command line option '-qf' (quickstart + config file) added (the same as
'-nocp -f')
- missing initialization of Ouser_shortcut in bx_options added
- PCI configuration space of the host bridge renamed from array[] to pci_conf[]
- new functions load_ROM() and mem_read() for ROM access
- macros for PCI functions defined in bochs.h
(from plex86 curses.cc)
- set the log action for the log level "panic" to "fatal", because the "ask"
menu causes trouble in the terminal
- logfile output to stderr not allowed
- handle_events(): type of variable 'character' must be 'int'
- two terminal chars added in function get_term_char()
- bit 7 of the vga attribute enables the A_REVERSE flag of the terminal char
(from plex86 curses.cc)
- variable term_attr no longer necessary in function text_update()
- function keys are working now
- clear_screen() function works now
- a few special vga characters converted to terminal characters
- exit() now clears the screen and calls endwin()
- "[TERM]" removed from info/error messages
- debug messages changed to BX_DEBUG
bitmaps. The bochs window now consists of 3 windows: the main window and
it's child windows simulation window and toolbar window.
Changes:
- new windows "mainWnd" and "simWnd" replace the old "hwnd"
- moved the functions of the old window procedure to the new ones
- toolbar functions added in create_bitmap(), headerbar_bitmap() and
replace_bitmap()
- function show_headerbar() no longer needed (must be present for
compatibility)
- a few variables for the headerbar changed or removed
- bitmap and headerbar variables now initialized in specific_init()
- added atapi layer
- updated int13_cdrom, int13_eltorito and int13_cdemu
- added verious DEBUG_XXX to debug only parts of the bios, because we're running low on data space in debug mode
- added a fix so bcc generates good code when #asm follows if or while statements
- updated int13_cdrom, int13_eltorito and int13_cdemu
- added verious DEBUG_XXX to debug only parts of the bios, because we're running low on data space in debug mode
- added a fix so bcc generates good code when #asm follows if or while statements
the guest OS. The shortcut can be defined in the bochsrc or in the config
interface. It is possible to change it at runtime.
These shortcuts are currently recognized:
ctrlaltdel, ctrlaltesc, ctrlaltf1, alttab
Here is the list of changes:
* userbutton.h and userbutton.xpm added in gui/bitmaps
* config options for the userbutton shortcut added
* initialize the new button in the gui.cc
* the new userbutton handler generates keypresses and relaeses depending on
the shortcut keyword
* the gui stops adding buttons to the headerbar if not enough space is left.
This can happen when the screen width is 320 pixels (done for X11 only).
* TODO: build a dialog box for the wxWindows gui
- 4 ata interfaces support (1)
- devices auto-detection
- 16bits/32bits device access
- EDD3.0 support
This is nearly the same BIOS I offered for download on July 12th,
but I hope to get more feedback with the CVS.
I will update this bios with the atapi bit and fixes, and
I'll eventually merge the changes in the main BIOS.
Added Files:
BIOS-bochs-new-ata rombios-new-ata.c
more work in the floppy and bios code.
- floppy and cdrom entries in the runtime config menu can be disabled if the
drive wasn't defined in bochsrc or start menu
- floppy variable "initial_status" and cdrom variable "inserted" renamed to
"status"
- unused variable *ips in function build_runtime_options_prompt() disabled
as no symbol. Now they will be relative to the last symbol.
- when anything was looked up in a segment with a nonzero base address,
it would print "non-zero base" and abort the lookup. I disabled this
behavior so that it would look up the symbol based on the EIP despite
the base. This change makes it possible to trace user processes, in
which the base is 0xc0000000.
- symbol lookup also used to fail in 16-bit code. Since the address
translations rules for 16-bit code are simple enough, I just compute
the 20-bit linear address and look up the symbol with it. Now I
can load a symbol table of the ROMBIOS and it works.
* new floppy type 360k can be used in .bochsrc and the config interface
* media type and geometry can be set for the floppy type
* BIOS changes to make 360k floppy drives work
* bximage can create 360k images now
Port 0x8901 is used. Two time values can be set and
read, along with the difference of the two.
Please look in the patch file for instructions on usage.
