HC Leadership Transition
@Andrew Dellow stepped up to take the Chair position for the SOC Infrastructure HC (Ved was the Chair). Call for Candidates for the Vice-Chair position is open.
AI/ML SIG Changes - Philipp (10 min)
AI/ML Apps SIG has never started
Plan to re-charter AI/ML SIG to cover both areas

The SIG has held no meetings since June 19, 2025 (9 months)
When meetings occurred (Mar–Jun 2025), average attendance was 3.2 out of 229 invitees
The mailing list has had 1 message in 2026 (CfC announcement only)
All 3 registered voters have lost voting rights due to inactivity per policy Section 2B #4
The open Call for Candidates (RVC-564) cannot proceed — no eligible voters, no quorum
The SIG has been active for nearly 5 years
The TSC disband the Graphics SIG (RVG-6), effective immediately. If approved, the motion directs:
Closing Graphics SIG Call for Candidates (RVC-564) without an election
Archiving the Graphics SIG in Jira (RVG-6)
Archiving the Group.IO mailing list (sig-graphics), GitHub repo (riscv-admin/graphics), and wiki workspace (link)
Parties interested in restarting the Graphics SIG may submit a new Proposal of Work

Meeting Summary
TSC Participation Status
The meeting reviewed TSC participation statistics for the first three months of the year, noting that some members had not met the 50% participation criteria. Jeff announced he would work with Ken to begin notifying members who were at risk of being put on probation due to low participation.
The team also discussed an unusual 90% participation rates in the voting system, with several members, including Guy and Greg, questioning whether they might have missed a vote, possibly during a Christmas meeting. Jeff agreed to investigate the issue systematically and provide an update to the group about any findings. Andrew clarified questions about attendance and voting rights, with Jeff confirming that alternate attendance counts toward meeting participation but not voting rights, and only one member per organization can vote.
Jeff confirmed later in the meeting that a calculation error was round in the spreadsheet behind the Participations Statistics wiki page. The information had been corrected and updated.
Minutes Approval
The meeting noted they were not yet at quorum and decided to skip minutes approval.
AI/ML SIG Changes
Philipp reported that the AI/ML SIG will be rechartering, merging in the newer AI/ML Apps SIG (not yet formally started and approved) into a single unified group. The rechartered group will work on a joint charter and will be expected to better integrate with other software enablement efforts.
Graphics SIG Disbandment
The discussion focused on proposed disbandment of the graphics SIG due to persistent inactivity and lack of leadership for at least 9 months. Rafael presented statistics showing the group lacks quorum for voting on new positions and has not been meeting or producing deliverables. From those present at the TSC, it was suggested to move to an OpaVote to disband the group, requiring a two-thirds majority approval since the current quorum is insufficient. The meeting then transitioned to welcoming guests from other SIGs, starting with Nick Brown from the HPC SIG.
HPC SIG
Nick Brown presented on RISC-V's progress in the HPC community, highlighting their workshop activities and gap analysis findings from 2025. He reported that 10 out of 15 popular HPC applications are already supported on RISC-V, and discussed five key recommendations including scaling out support, file system improvements, software ecosystem development, and better compiler support. Nick identified hardware as a significant challenge, noting that current RISC-V CPUs are underperforming compared to earlier models like the C920, and emphasized the importance of high-performance CPUs to support NVIDIA's planned CUDA port to RISC-V.
Nick Kossifidis proposed collaborating on bringing back user-level interrupts for HPC, which Nick Brown expressed interest in but noted challenges in fitting this into current HPC priorities. The discussion then shifted to matrix standardization, where Nick Brown expressed skepticism of the relevance of IME for HPC given its lack of FP64 support, though Philipp clarified that HPC requirements were being considered. Krste provided insights on the market dynamics, explaining that CPU developments would likely be driven by the server market rather than HPC-specific needs, with RISC-V potentially playing a role in both CPU and accelerator spaces, particularly for VME rather than IME.
DTPM SIG
The topic focused on the Debug Trace and Performance Monitoring (DTPM) SIG's activities and progress. Ian Robertson, chair of the DTPM SIG, presented an overview of the group's work, including overseeing of four active technical groups (TGs) focusing on event trace, self-hosted trace, instrumentation trace, and external debug security. The SIG is also working on extracting the heart-to-trace interface into a standalone specification and exploring standardization for on-chip logic analyzers.
A key discussion point raised by Philipp was about consolidating gap analysis data into a central location for better tracking and transparency, which Jeff agreed to take as an action item to determine the best approach for leveraging this data. The conversation ended with Jeff noting that quorum was not reached, so the OpaVote for disbanding would proceed, and meeting minutes from the past three months would be carried forward for approval at the next meeting.
Detailed Minutes
TSC Participation Status
Jeff confirmed a bug in the Participation Statistics data which was updated during the meeting.
Please raise any additional questions to Jeff directly or help@riscv.org.
AI/ML SIG Changes
Work underway to merge AI/ML (active) SIG and new AI/ML App SIG together
Next Step: Charter update from AI/ML SIG
Minutes Approval
Did not reach quorum.
Will roll into May meeting.
Graphics SIG Disbandment
Group inactive, we don’t have leadership, nor do we have a quorum for voting
Next Step: OpaVote to TSC to formalize the decision
HPC SIG

Discussion:
How useful is the AME/IME/VME extensions for HPC?
Depends on the datatypes supported. We need more collaboration here between the TGs and HPC SIG.
IME might be the most interesting here with the assumption that it may have higher precision constraints.HPC processors are typically server processors and accelerator processors. RISC-V will likely begin adoption with accelerators out of simplicity of change in architecture.
