Notes
Meeting Agenda:
The agenda was approved upon a motion by David Weaver and seconded by Andrew Dellow.
CHERI:
Jira Legacy server System Jira serverId 4d3dce95-b4be-35da-b49f-ec8432d8f473 key RVS-2141 There are no issues with trademarks or other related concerns, as the University of Cambridge is ensuring that it is in the public domain.
Is there any impact on the hypervisor (see https://github.com/riscv/riscv-cheri/blob/main/src/hypervisor-integration.adoc ) or the debug/trace functionality (see https://github.com/riscv/riscv-cheri/blob/main/src/debug-integration.adoc).
How is this divided up in multiple extensions? (add the link here)
All initial 4 are extensively prototyped.
Freeze all as a package:
CHERI is disabled by default.
Coordinate with Memory Tagging Group on OPCODES (
)Jira Legacy server System Jira serverId 4d3dce95-b4be-35da-b49f-ec8432d8f473 key RVG-161 By design, one HART can run with CHERI enabled while another runs without it.
Ensure Guerney Hunt have a deep discussion within the CHERI TG/SIG.
Robert Chyla asked to consider some time prior the start of the internal review to better evaluate the plan and the proposal.
What other security extensions can/cannot be used in conjunction with CHERI?
Performance: CHERI Core vs non-CHERI core.
Small performance penalty.
Python, C, C++, Java, Rust as languages/run-times supporting CHERI.
Tariq Kurd Work with Allen Baum on ACTs definitions.
Convert Codasip tests to ACTs.
Extension will use a relaxed and longer period of time for reviews.
