From 31e27d455969d33190d28917ef98f034888d217b 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. --- debug/risc-v-gsp-rm-vm/greeneye/errors.py | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 debug/risc-v-gsp-rm-vm/greeneye/errors.py (limited to 'debug/risc-v-gsp-rm-vm/greeneye/errors.py') diff --git a/debug/risc-v-gsp-rm-vm/greeneye/errors.py b/debug/risc-v-gsp-rm-vm/greeneye/errors.py new file mode 100644 index 0000000..fab5874 --- /dev/null +++ b/debug/risc-v-gsp-rm-vm/greeneye/errors.py @@ -0,0 +1,30 @@ +"""green-eye error types.
