Vector version supported by Olympia?

[quasiquote1]

Hi - I was wondering what is the latest status of the vector specification that is supported in Olympia? I was told in the Performance Modeling SIG that the support may not be fully there. Thanks.

@kathlenemagnus can you give a brief update on this?

Hi @quasiquote1. Unfortunately, vector is not fully supported in the Olympia model yet. Here is what is supported today:

• RVV 1.0 decoding with Mavis
• Vector uop generation for RVV 1.0 excluding some permute instructions (see Added Vector 1.0 Uop Generation Support #247)
• Vector instruction execution for RVV 1.0 vector-vector instructions
• Vset instruction processing in Decode with proper stall handling

Aside from my occasional contributions, I am not aware of anyone who is actively working on extending vector support for Olympia.
