f90e5f4f44 Add initial implementation of the CET (Control Flow Enforcement Technology) emulation according to SDM071
Only missing items (to be added soon):
  - Supervisor Shadow Stack EPT Control is not implemented yet

2a55ba0a39 Merge set of debugger improvements by Doug Gale <doug16k>
Here is his original comment:

I have made several improvements in the debugger.
I have fixed several issues with proper handling of 64-bit addresses, and added support for 64 bit symbols.
I also have added several symbol lookups.

7a34f00f99 extracted fetchdecode into separated folder under cpu and also out of BX_CPU_C class into stand-alone module. Next step: wrap it up nicely and define clear interace to CPU model to minimize dependencies. Ideally I need fetchdecode to not include CPU at all 2016-06-12 21:23:48 +00:00

ab87549b6b Updates to Bochs debugger:
AVX command split into two: YMM command and ZMM command for AVX-256 and AVX-512.
Later new command AVX will be added whch will print complete AVX state according to what is defined currently, including OPMASK registers

info device <name>
and
info device <name> <string>

could be also used now without having to include device name in quotes as "name".
old style "qouted" option also still working

added missing info cpu command to the help

f65c4e66b8 - debugger command 'info device': implemented support for additional arguments
- ne2k: replaced debugger command 'info ne2k' completely by a new version based
  on 'info device' with additional arguments and removed all of the now obsolete
  stuff (ne2k device stub, macro for print_info())
- pci: added option 'dump=full' for the debugger command 'info device' to show
  the whole PCI config space
- TODO: some other devices could have support for additional options in
  debug_dump()

086266d033 - implemented new debugger command 'info device [string]' that shows the state
of the device specified in 'string'. Added register mechanism and chained
  list to store the device name and pointer. Replace hardcoded debug info
  implementations for pic, pci and vga by the new one.
- TODO #1: improve existing debug_dump() output and add more devices
- TODO #2: add support for additional arguments and replace the NE2k print_info()

92bb77ef1d Merge patch from SF tracker:
[3298173] Breakpoint on VMEXIT event by Jianan Hao

Patch description:

The patch provides a new command "vmexitbp" to set breakpoint when VM guest exit. The simulation will be stopped before first HOST mode instruction is executed.

Usage:
Type "vmexitbp" in debugger command window to switch it on/off (similar to modebp).


Currently, the patch has no corresponding interface on GUI debugger. Someone may add it if interested.
