X86 Todo List

Highest priority

• Flesh out and debug 64-bit modern ISA (what's needed by users)
• Complete x87 support
• AVX support
• 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)
• In-order pipeline core model support
• Out-of-order core model (O3) support
• Multiprocessor timing support
  • MP situation is OK in atomic mode since all memory ops are atomic
  • Need to enforce atomicity of locked mem ops in timing cache models
    • Ruby and M5 classic?
• more complete M5 hooks in Linux kernel (porting what we had in Alpha)

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, ??)
• 32-bit user-level support (SE mode)
• 32-bit full-system support (FS mode)
• real mode support
