xiangshan-mpt-dut skillA

xiangshan-mpt-dut is agent-read markdown (skill) from openxiangshan/xiangshanlab: Generate or update a compact Chisel/Scala DUT that isolates XiangShan MPT checking logic from the full core. Use when working on XiangShan MPT, MptChecker.scala, L2TLB MPT wiring, backend/decode mfence support, or the custom smmpt/mmpt CSR path, especially when asked to regenerate a simple DUT around MPT upstream/downstream logic for simulation or verification..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add openxiangshan/xiangshanlab/xiangshan-mpt-dut@git:20260724.bb8f3f1
Exact content
mdr add openxiangshan/xiangshanlab/xiangshan-mpt-dut@sha256:5aadaf6dc64ac302

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
