version: "1.0.0" name: riscv-security-hc-spec description: > Look up RISC-V Security Horizontal Committee related specifications, including ratified and unratified/development specs. Activate for questions about RISC-V security specifications, memory isolation, memory encryption or confidential computing, I/O isolation, secure interrupts, trusted debug, and control-flow integrity including Zicfilp and Zicfiss.

RISC-V Security HC Specification Lookup

Rule

Do not answer RISC-V Security HC specification-status or source-link questions from memory. First check the bundled specification index and, for current status, verify against the official sources listed there.

Primary Reference

Read references/security-hc-specifications.md when the user asks about:

• memory isolation: PMP, Smepmp, SPMP, Smmtt, Worlds, Smpmpmt
• memory encryption or confidential computing: Security Model, CoVE/AP-TEE, HAC, crypto
• I/O isolation: IOMMU, IOPMP, CoVE with I/O
• secure interrupts: AIA, PLIC, CLIC, NMI/double-trap related privileged extensions
• trusted debug: Debug, external debug security, trigger delegation
• control-flow integrity: Zicfilp, Zicfiss, Smcfilp, Smcfiss, shadow stacks

Status Sources

• Ratified specs: https://riscv.org/specifications/ratified/ and the official RISC-V docs library.
• Development specs: https://riscv.org/specifications/ -> "VIEW DEVELOPMENT SPECS", backed by https://riscv.github.io/adm-spec-dashboard/latest.csv.
• If GitHub access is blocked in this environment, run network commands through bosc-ipv6, for example:

``bash bosc-ipv6 curl -L https://riscv.github.io/adm-spec-dashboard/latest.csv ``

Answering Guidance

When answering, report:

1. specification name and extension names where applicable;
2. status: Ratified, Development, Stabilization, Freeze, Ratification-Ready, or Planning;
3. whether it is ISA, NON-ISA, or both;
4. official source link;
5. the security category.

If a requested category has no direct public RISC-V spec entry, say so and name the closest related specs instead of inventing one.
