Related configure options (--enable-pae, --enable-mtrr, --enable-global-pages, --enable-large-pages) are deprecated.
Less configure options - less configure problems :)
'sdl'. Now both display libraries can be compiled together and used with the
'show ips' feature. TODO: win32-specific 'show ips' timers for 'rfb' and 'wx'
the existing runtime dialog ('textconfig' is still available)
- removed notify callback redirection from sdl.cc and win32.cc
- removed win32 specific code from textconfig.cc
- fixed parent window for folder selection dialog
- minor size changes in start menu dialog
* initialize plugin system before parsing bochsrc and command line
* pass previous value to bx_param_string_c handler
* load / unload plugin in bx_param_string_handler()
* handle user plugins after optional ones in plugin device init, reset and
save/restore functions
* added new siminterface method unregister_user_option()
* removed first version of config option handling for user plugins
* added new parameter subtree for user-defined options
* added new bx_list_c method remove()
* removed unused bx_devmodel_c method init_mem()
There is a trick in MSVC is to turn on the -Gr compiler switch which tells MSVC to compile all functions using fastcall calling convention. This way you don't have to edit each function declaration. But certain functions must NOT be fastcall, and those are callbacks from Windows which are defined either as cdecl or stdcall. The entry point main() also has to remain cdecl.
Patch by Darek Mihocka
Make save/restore default feature, the configure option for save/restore removed from configure script and save/restore made available forever. All code now assume it is exists. Bochs save/restore tree previosly called "save_restore" renamed to "bochs" tree and it will be havily used everywhere, starting from save/restore and ending by various bochs debugger functions. I am going to rework debugger code to get rid of debug CPU access functions and use this "bochs" param tree instead
* wxBochsStopSim flag is now reset before starting the SimThread
* the siminterface 'init_done' flag now controls the execution of the hardware
cleanup in bx_atexit()
[ bochs-Bugs-1562172 ] TLB_init() fails to initialize priv_check array if USE_TLB 0
2. Paging is always exists for i386+
To disable paging it is better to use normal model without special code, only by setting cr0.pg=0
done by the object destructor (changes in cmos, hard drive and keyboard)
- bx_unload_plugins() now deletes the devmodel object in non-plugin mode
- CMOS device now prints the time on exit in human-readable format
- added exit() method to the devmodel object for devices that need to do special
cleanups on exit. Device plugins should call this method from their plugin_fini()
function. If Bochs is compiled without plugin support, for non-core plugins
the exit() method is called directly from bx_unload_plugins().
- exit() method implemented in the keyboard device
- wx "Show Keyboard" feature now only appear when the wxdebug keyboard subtree
is not empty
- cpu cleanup must be done before the devices cleanup
- moved PCI chipset dump call to the devices exit method
* don't initialize cpu specific parameters for the wx debugger if they already
exist
* separate siminterface method init_save_restore() added
* old wx specific handling in quit_sim() removed
* new bx_list_c method clear() deletes all parameters from the list
* moved devices cleanup code from the pc_system to a new devices method exit()
* pc_system init code now sets ticksTotal to 0
* register_state() will be called after init() and registers the device members
required for save/restore
* before_save_state() can do some work before the device state is saved by the
siminterface
* after_restore_state() can do some work after the device state has been
restored (updating dependant stuff)
- for the BrowseDir() function Bochs for win32 needs to be linked with SHELL32.DLL
(currently used for the save/restore support only)
- save/restore support symbol name changed
- log options must be restored after initializing all devices
- menu items and descriptions for save/restore updated
- TODO: implement access to save/restore functions for win32 and wx
- don't load another config file if the restore flag is set
- disabled restore_hardware() for now (will be enabled when save/restore is
complete and stable)
parameters of the wx debugger possible
- started rewrite of shadow parameters and converted keyboard parameter stuff
- test function print_tree() now shows raw byte strings correctly
- removed unnecessary spaces
Averything that required cpu.h include now has it explicitly and there are a lot of files not dependant by CPU at all which will compile a lot faster now ...
- parameter tree structure updated (TODO: should be moved to development.dbk)
- code cleanup: bx_options stuff and obsolete parameter access methods removed
- TODO: rewrite of shadow parameter stuff (for subtree "save_restore")
- siminterface get_param_*() methods num support a base parameter like the generic
get_param() method
- new parameter lists now also have a generated id
- test function print_tree() now handles enum parameters correctly
- proposed parameter tree updated
- boolean parameter type now supports new parameter handling
- new parameter object constructors now supports label initialization
- bx_list_c constructor now supports title initialization
- textconfig: initial support for new parameter handling
- wx: missing CPU config dialog added
- wx: ParamDialog now handles disabled parameters correctly
- removed unnecessary spaces from function calls
* memory parameter handling rewritten (not yet complete)
* new reset() method for bx_list_c for recursive reset of all list members
* memory options in wx now handled in a ParamDialog (ConfigMemoryDialog removed)
* removed obsolete BXP_* constants in siminterface.h
* updated proposed parameter tree
- constant BX_N_OPTRAM_IMAGES for optional RAM images limit added
Change BxSupportPAE and BxSupportGlobalPages macros to Bochs style names
Set bx_cpu_id in BX_CPU_C constructor (safe way)
Backup cpu-level check for paging features at compile time (already checked in configure)
Some warnings and indent fixes
speed up get_segment_base method for x86-64 case
optromimage. You can load up to 4 arbitrary binary images into RAM.
I didn't do any checking on the addresses, so it's up to you to make
sure they don't collide with anything else. Should only be used for
placing files into standard RAM.
present and a quickstart option exists, too
- improved check for GTK 2.x (only needed if basename of wx is 'wx_gtk2')
- moved/added some deprecated configure options to the end of the script. These
checks should force users and distrubutors to update their config options.
- fixed pcidev targets in iodev/Makefile.in
- updated all Makefile dependencies using a default setup (.conf.linux).
TODO: dependencies should be generated at compile time since they depend on
the config settings
- vgaromimage option now compatible with the other rom options. Old style syntax
(without 'file=...") is still supported.
- load order for the rom images fixed (system, vga, other)
- rom images sizes not multiple 512 cause a BX_INFO for now. The original check
will be enabled after updating the vgabios files
- optromimage error messages fixed
- some updates of the bochsrc sample
2. Fixed bug
[ 989478 ] I-Cache and undefined Instruktions
The L4 microkernel uses an undefined instruction to
trap for a special requests into the kernel (LOCK NOP).
The handler fixes this up and gives the user a special
code page with syscall stubs. If you're not using the
I-Cache optimization everthing works find on bochs. But
if you enable the I-Cache (--enable-icache), then the
undefined opcode exception is thrown only once for ever
virtual address it occurs. See the demodisk of the
L4KA::pistachio
(http://www.l4ka.org/projects/pistachio/download.php).
In this case the pingpong benchmark of this demo is of
interest. Everything runs fine until the program tries
to spawn a new task for its measurements. This new task
shares the code of the creating program. But the new
task stops executing at the undefined instruction
explained above and no exception is thrown.
bochs.h already not include iodev.h which reduces compilation dependences for almost all cpu and fpu files, now cpu files will not be recompiled if iodev includes was changed
- textconfig runtime menu: some options moved to submenu "Misc runtime options"
- bx_param_c: variable group_name and methods set_group() / get_group() added
- bx_list_c: new flag SHOW_GROUP_NAME added (used for SB16 options in runtime menu)
