From ba58dcdc5ad6ca021c723d279f33e3f14e1184df Mon Sep 17 00:00:00 2001 From: Arthur Hanson Rasmusson Date: Fri, 2 Oct 2026 08:36:35 -0400 Subject: debug: add green-eye GSP/uproc RISC-V VM runtime analysis tooling Adds open-iov/debug/risc-v-gsp-rm-vm: a GDB-free instrumentation stack that boots uproc/GSP firmware in qemu-system-riscv64 and provides Frida-like hooks, breakpoints, watchpoints, memory dumps, structure decoding, snapshot diffs, recorded sessions, declarative probes, a plugin API and a Ghidra symbol/hit bridge. Verified: 25 tests green (including a live QEMU smoke test); the demo uproc boots with correct hook/leave/watch/schema/snapshot/fault evidence; the optional TCG trace plugin builds and recorded 15M trace lines in 3 s; the TU104 570.144 fwimage probe reports its first exception (load access fault at firmware vaddr 0x4009014 reading 0x2000000000000A00). Documentation: lean tool docs under debug/risc-v-gsp-rm-vm/docs/00-10, a new docs/05-operations/03-risc-v-gsp-rm-vm.md debugging document, and '# TOOL IN DEVELOPMENT - NOT READY YET!' markers in docs/README.md, the onboarding tooling table and the debugging workflows doc. Vendors qemu-plugin.h from QEMU v8.2.2 (GPL-2.0-or-later), with its license header intact, so the optional TCG plugin builds without a QEMU source tree. --- docs/07-developers/onboarding-and-standards.md | 1 + 1 file changed, 1 insertion(+) (limited to 'docs/07-developers') diff --git a/docs/07-developers/onboarding-and-standards.md b/docs/07-developers/onboarding-and-standards.md index 241e03f..e62ec28 100644 --- a/docs/07-developers/onboarding-and-standards.md +++ b/docs/07-developers/onboarding-and-standards.md @@ -158,6 +158,7 @@ The following rules each come from a real bug and are enforced in review: | `tools/firmware_analyzer.py` + Ghidra scripts | firmware analysis pipeline | | module debug parameters | guest-memory scanning/poking, VRAM inspection | | QEMU gdbstub workflow | guest virtual-memory inspection/writing | +| `debug/risc-v-gsp-rm-vm/` (green-eye) | **# TOOL IN DEVELOPMENT - NOT READY YET!** — RISC-V GSP/uproc VM runtime inspection, session recording and `gsp-rm-vfio` accuracy measurement (see [`../05-operations/03-risc-v-gsp-rm-vm.md`](../05-operations/03-risc-v-gsp-rm-vm.md)) | | `wiki/` documents | protocol and firmware deep dives | ## 5.
