Additional Notes:

The quorum for the meeting was achieved by 07:10 AM PT.
UnifiedDB SIG Proposal - @Derek Hower
- At 07:23 AM PT, UnifiedDB was approved by TSC Chairs (@Philipp Tomsich and @Greg Favor (Unlicensed)) to proceed to the broader review by RISC-V Members.
- The relationship between UnifiedDB and TSC/CSC will be determined later, as the new policy does not include the concept of a dotted-line relationship.
- Recommendation from @Philipp Tomsich to @Derek Hower is to be clear on the dependencies/relationships and on the roadmap of UnifiedDB.
Strategic Priorities - @Greg Favor (Unlicensed)
- Help @Guy Lemieux on how to handle multiple inputs (large scale) that will emerge from Community (Orgs and Individuals).
- What other Profile Families should be developed?
- From @Philipp Tomsich on software: ecosystem is evolving. A lot happening upstream.
- From @Ravi Sahita what about Security?

Presenter: Derek Hower (Qualcomm)
Discussion Points:

Background on UDB:
- An open-source project capturing machine-readable versions of the RISC-V spec.
- Aims to improve documentation generation, certification artifacts, and interoperability.
- Significant community engagement, with multiple companies contributing.
Proposal for UDB SIG:
- Merge previous proposals into a unified framework for organizing and structuring specifications.
- Close collaboration required with ARC (Architecture Review Committee), Documentation SIG, ISS/IDL teams, Toolchain SIG, and Compliance & Security Committees (CSC).
- Potential role in automating test plans and validation tools.
Governance & Next Steps:
- SIG to be placed under the ISA Infrastructure Committee.
- Proposal will be reviewed further, with next steps involving TSC and Board approval.

Decision:

Approved to proceed to the next step (POW review).
Concerns noted:
- Overlapping efforts with other initiatives like the Golden Model.
- Coordination with ongoing documentation and certification processes.
- Need for clear scope and integration with existing standards.

Presenter: Greg Favor (Ventana)
Discussion Points:

Objective: Identify architectural gaps that need to be addressed for RISC-V’s roadmap.
High-priority areas from the Board:
- AI/ML
- Automotive
- Security Model
Process Overview:
- Each TSC voting member (Strategic, Premier, Community Representatives) will receive a template Wiki page to outline their architectural gaps and priorities.
- Five key categories:
  1. ISA Gaps
  2. Hardware Non-ISA Extensions
  3. Software Non-ISA Extensions
  4. Profiles
  5. Platforms
- Members will submit priorities within two weeks.
- The TSC will review and aggregate the responses to identify common themes.
- The results will be redirected to the relevant SIGs, ICs, or HCs for potential action.
Discussion & Clarifications:
- Security concerns will be addressed across categories rather than as a separate section.
- Emphasis on practical implementation, not just identifying gaps.
- Need for actionable results from this effort.

SIG & Task Group Elections:
- Elections for SIG and Task Groups are being planned.
- Policy stabilization discussions will continue in the next Technical Operations meeting.
