fda4d38959 32-bit systems have a problem to allocate large amount of physical memory for Bochs simulation which makes simulation with 4G address space virtually impossible. But in most of the cases when 4G physical address space defined - it is not touched by default on every run so it is possible to allocate only really accessed blocks. This commit made all necessary preparations for it. 2008-04-17 14:39:33 +00:00

071c5c1a26 A lot of changes but everything is really trivial. 
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

37eb82c69c Totally remove the cosimulation code from Bochs. 
The Bochs anyway even doesn't compile if cosimulation configured enabled.
But in the same time the cosimulation code only disturbs to the future development of Bochs debugger, for example adding x86-64 functionality ...
For those of you who still may want to see the cosimulation code inside I put it in patch and upload it Bochs CVS patches folder. Read comments for the patch ! ----------------------------------------------------------------------

18afa9fd2d This is cumulative patch for bochs debugger, it is only very first step towards working debugger supporting all new simulator functionalitieS. 
- move crc.cc from debugger to bochs folder and make it projct-wide and not local for debugger
 - added new 'info sse' command for debugger
 - extend 'modebp' command to break on any mode change
 - remove unimplemened 'info program' function, it is always printed fixed text
 - move debugger help to parser, cleanup and simplify it

641650e7e1 Added optramimage directive for .bochsrc files, with same syntax as 
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.
