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

NMI support inside the CPU.

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)

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.
