DVP

Data Value Prediction Restriction by Context prevents data value predictions, based on information gathered from earlier execution within an particular execution context, from allowing later speculative execution within that context to be observable through side-channels.

For more information, see DVP RCTX, Data Value Prediction Restriction by Context.

This is an alias of SYS. This means:

  • The encodings in this description are named to match the encodings of SYS.
  • The description of SYS gives the operational pseudocode for this instruction.
