X86 Todo List

Highest priority

• Flesh out and debug 64-bit modern ISA (what's needed by users)
• FS-mode core timing issues
  • Debug TimingSimpleCPU issues?
  • In-order pipeline core model support
  • Out-of-order core model (O3) support
• Multiprocessor timing support: need to enforce atomicity of locked load/op/store sequences in timing cache models
  • Ruby and M5 classic?
• Performance correlation
  • With real hardware and/or existing correlated simulator
  • Micro-op counts for functional implementation
  • Timing for out-of-order core (requires O3 support)
• Complete x87 support
• AVX support

Useful but not strictly necessary

• Split up ISA output for faster compiling
• Improve ISA description language support for x86

To do eventually but not right away

• ACPI support
• KVM-based fast functional CPU model
• Virtualization extensions support (AMD SVM, etc.)

Could be done but might never happen

• other OS support (OSX, Windows, ??)
• complete real mode support
