take RAW_BYTES string out of bx_param_string_c into new param type bx_param_bytestring_c (better name, anybody?)
this is intermediate step, later it would be better to merge bx_param_string into generic template bx_param<type>
but bx_param_bytestring_cis not matching that concept (or probably will continue to inherit from bx_param<string>)
the method dumps param to the FILE
use new method do dump param tree during save/restore
also make more use of parse_param methods which initialize param from a string
- Added capability to save/restore float type values in paramtree / siminterface.
- Added Voodoo2 triangle generator data to save/restore list.
- Implemented bitBLT function "SGRAM fill".
- Minor other changes and cleanups.
- TODO: remaining bitBLT functions, thread handling improvements.
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.
- Add a special list to the MSD state and add pointers to the runtime-only
options for the cdrom. The restore handler of this list calls runtime_config()
to make sure the media path and status are correctly updated.
- Registering a runtime config handler for the USB cdrom is not necessary since
runtime_config() is always called from the hub it is connected to.
- Restore a string parameter value only if it's different from the initial one.
with devices conected at runtime.
- Added restore handler support for the bx_list_c class. If a handler is
registered, it will be called after restoring all of the list's members.
- USB hub: add special lists to the port state and add pointers to the
runtime-only options for each port. The restore handler of this list calls
init_device() to make sure all connected devices can be restored.
- Call restore_logopts() after restoring hardware to make sure all saved
modules have been created.
- TODO: the USB cdrom also needs a fix for it's runtime-only options.
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
This fixes the floppy malfunction after restore and maybe other issues. The
buggy code failed to clear the DMA controller mask bits and the floppy DMA
requests never arrived at the CPU.
- device prefix size needed update, but now using log function name instead
- don't use overlapping strcpy() (increment pointer and one single strcpy())
- now using get_logfn_id() to simplify code
TODO: fix floppy access failure after restore
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
- bx_list_c: added support for removing parameter with other parent list
- USB HC's: remove item from runtime config on simulation exit
- initialize bx_user_quit in bx_begin_simulation()
- only remove optional plugin from list if alrady unloaded
- 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 trigger_timer() methods to refresh_display()
- new argument 'redraw' added to force a refresh of the entire screen
(used in snapshot mode)
- siminterface method refresh_vga() now checks if the Bochs gui init is complete
- use SIM->refresh_vga() in some more cases
undoable, volatile)
- TODO: save state function for the remaining image modes, restore support
- save/restore: when saving binary data to a file, use the full parameter path
(except "bochs." prefix) as the file name to avoid overwriting duplicates
dummy parameter and it's save/restore handlers. Currently only the save
support is implemented and the specific save function is only written for
flat mode images (copies whole disk image file to the save/restore folder).
- TODO #1: implement save function for the other disk image modes
- TODO #2: add restore support (replace disk image file with the one from the
save/restore folder)
- re-implemented siminterface method is_wx_selected() (the old one had been
renamed to has_debug_gui() which is something different now)
- don't use alarm() if the wx gui is selected and instead use the wxTimer based
code that already exists for wxMSW
- ported Qemu block driver (written by Alex Beregszaszi and Kevin Wolf)
- added helper functions bx_read_image() and bx_write_image()
- TODO: use helper function for the other disk image modes
- SIM->opt_plugin_ctrl() now can be used to verify the optional plugin
configuration when using the plugin name "*". The 'load' value 1 makes
sure that all plugins with the value 1 are loaded. The 'load' value 0
unloads all plugin with the value 0 (marked for removal).
- add the default set of plugins to the 'plugin_ctrl' list and load all these
pre-defined optional plugins before parsing the configuration.
- special wx case: verify plugin configuration before showing the plugin
control dialog and before initialising hardware.
- device plugins that have been loaded, but not configured now set their
plugin control value to 0. Added the plugin unload check before signalling reset.
- enh_dbg: fixed defined-but-not-used warnings
- siminterface: renamed 'wx_debug_gui' to 'bx_debug_gui' and updated comments
- TODO: remove the wx debugger and use the enhanced gui debugger instead
