This patchset is sent as RFC because RVV v0.9 is still in draft state. However, as RVV v1.0 should be ratified soon and there shouldn't be critical changes between RVV v1.0 and RVV v0.9. We would like to have the community to review RVV v0.9 implementations. Once RVV v1.0 is ratified, we will then upgrade to RVV v1.0. You can change the cpu argument: vext_spec to v0.9 (i.e. vext_spec=v0.9) to run with RVV v0.9 instructions.
