Numbers in the squares below refer to the following notes:

 +
# Ruby does not support atomic-mode accesses
 +
# The MI_example protocol cannot support LL/SC semantics
 +
# Ruby does not support probing the O3 LSQ to enforce non-weak consistency models
 +
# ARM MP does not support booting with caches, but works otherwise.  You can boot without caches then switch to running with caches using either a checkpoint/resume or on-line CPU switchover.

The follow six tables describe the current state of component combinations in gem5.

Notes

Numbers in the squares below refer to the following notes:

  1. Ruby does not support atomic-mode accesses
  2. The MI_example protocol cannot support LL/SC semantics
  3. Ruby does not support probing the O3 LSQ to enforce non-weak consistency models
  4. ARM MP does not support booting with caches, but works otherwise. You can boot without caches then switch to running with caches using either a checkpoint/resume or on-line CPU switchover.
