9340f3b3f8 - partial sync with BRANCH_SAVE_RESTORE_3 (hardware save/restore not present yet)
* changed data format of text files for save/restore (looks like C/C++ structures,
    similar to the format used in old save/restore branches)
  * don't set the initial value of shadow bool parameters
  * don't set the initial value of bool parameters twice
  * cpu/init.cc: missing #undef added
  * ne2k.cc: variable tx_timer_active was never set to 1 (type now bx_bool)
  * floppy.cc: missing initialization of the 'eot' array in reset() added
  * pic.h: type of member 'byte_expected' changed to Bit8u
  * pit_wrap.h: unused members removed

b2408c2fca Added assertion check CPU method, could be used for "debug mode" run with checking various assumptions before each instruction emulation 2006-04-25 14:42:57 +00:00

52c4666465 - partial sync with BRANCH_SAVE_RESTORE_3 (hardware save/restore not present yet)
* fixed minimum limit of signed variable types
  * don't set the initial value of shadow parameters
  * fixed range check for shadow parameters
  * added support for setting the value base (decimal/hex) of numeric shadow parameters.
    The text format hex number is now initialized in the constructor
  * added missing newline after filename for binary data
  * fixed data size of 64-bit shadow parameters
  * fixed save/restore output format of numeric parameters (signed/unsigned/64-bit)
  * cpu/init.cc: fixed macro name and added missing #undef line

f8c3968d42 Changes list made after CVS service crash:
- Fixed critical bug in CPU code added with one of the prev commits
  - Disasm support for SSE4
  - Rename PNI->SSE3 everywhere in the code
  - Correctly decode, disassemble and execute 'XCHG R8, rAX' x86-64 instruction
  - Correctly decode, disassemble and execute multi-byte NOP 0F F1 opcode
  - Fixed ENTER and LEAVE instructions in x86-64 mode
  - Added ability to turn ON instruction trace, only GUI support is missed.
    Instruction trace could be enabled if Bochs was compiled with disasm
  - More changes Bit32u -> bx_phy_address
  - Complete preliminary implementation of SMM in Bochs, SMI is still PANICs but if you press 'continue' everything should work OK
  - Small code cleanup
  - Update CHANGES and user docs

d6f85c12f6 NMI support inside the CPU.
Added two functions to query NMI and SMI from Bochs debugger.
In future they could be used for generating NMI or SMI by user request using GUI button (could be implemented separatelly later and under configure-time or .bocshrc option)

7b6c2587a9 Now devices could be compiled separatelly from CPU
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 ...

203a9caf31 SMM mode could leave together with pmode or any other (according to amd docs)
so we need separate bx_bool indicator in_smm instead

024ce249bf Define SMM mode for future implementation.
I would like all next commits be aware of SMM mode.
It can't be implemented right now (too many questions w/o answers) but it will be done till next major release definitelly.

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

7bf51e48db Print FS_MSR_BASE and GS_MSR_BASE to debug registers dump (requested in bug report [ 1406387 ] JMP instruction should display absolute address)
Fixed fetch mode mask initialization (bug report 1400027  Boundary instruction cache error for uninitialized memory)
For safety only - everytime when changing CS register update fetch mode mask.
Actually it need to be updated everytime when there is a chance for execute mode change or 16/32 bit mode change.
