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
finally the shutdown handling should be done exactly as in VmWare - the GUI should ask user if the CPU should reset and go to HLT/IF=0 if user choosed to stay in shutdown mode.
CPU configure option reset-on-triple-failt should be extended to shutdown-reset=0|1
small code cleanups and fixes
- 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
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 ...
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.
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.
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
