- Added build_hp_rtthread.py for building the RT-Thread kernel with RV64 support. - Updated build_hp_smoke.py to target RV64 architecture and modified output filenames. - Modified generate_vexiiriscv.py to reflect RV64 configuration and memory management. - Created hp_tools.py for shared utilities related to RV64 builds. - Enhanced package_hp_boot.py to package RV64 workloads and updated versioning. - Implemented run_hp_sim.py for executing and validating HP workloads with specific markers. - Developed setup_hp_rtthread.py for installing RT-Thread source and environment setup. - Updated GenerateRetroSocHp.scala to generate RV64 application cores. - Enhanced tests for HP boot bundles, platform specifications, and tool utilities to accommodate RV64 changes. - Adjusted test cases to validate new workload types and ensure compatibility with RV64 architecture.
Build and Quality Scripts
This directory contains the Python implementation of setup, dependency locking, build manifests, flow execution, simulation checks, regression orchestration, quality checks, metrics, packaging, and cleanup.
apu_mcasm.py, apu_isa.py, apu_interpreter.py, and apu_primitives.py are
the frozen APU microcode V1 assembler/ABI model, P3/P4/P5 target interpreters, and
bit-accurate P4 primitive model. They accept only the APU instruction language
and deliberately have no C, ELF, RV32, dynamic linking, or runtime
code-generation path.
setup_apu_reference.py installs the checksum-pinned libFLAC and official
FLAC corpus as host-only P5 verification inputs and builds libFLAC with Ogg
disabled below the selected build variant. These inputs never enter firmware,
RTL, or shipped APU microcode.
qualify_apu_p5_corpus.py enumerates that exact corpus, records source and
decoded-PCM hashes, and classifies each file against the frozen P5 profile.
run_apu_p5_corpus_rtl.py then runs every classified file through one shared,
verification-only apb4_apu fixture compiled for Icarus and Verilator. It
records exact production result/accounting and PCM hashes in the same manifest;
per-case results are resumable and neither the fixture nor corpus enters a
product filelist.
Scripts are part of the build contract. Prefer existing helpers over ad-hoc
shell behavior, preserve structured JSON results, and keep setup/download
behavior controlled by dependencies/dependencies.lock.json.
development_environment.py is the shared Docker, Nix, and manual bootstrap
entry point. It installs only the checksum-verified open-source tool bundles and
hash-pinned Python dependencies; project-local PDK and source setup remains under
the existing Make targets.
publish_fatfs_artifact.sh is the manual release helper for the lock-pinned
FatFs R0.16 archive. It verifies the archive, GitHub authentication, release
absence, and the published asset checksum before reporting the checksum-pinned
URL.
parse_performance_log.py converts the APP=benchmark UART PERF records
into meta/performance.json. The parser requires the terminal
PERF_BENCHMARK_PASS marker. parse_coremark_log.py converts the fixed
SRAM CoreMark quick report into meta/coremark.json; it requires one valid
COREMARK_RESULT record and COREMARK_PASS. Both reports complement, rather
than replace, the common SIM_TEST_PASS simulation verdict.
generate_vexiiriscv.py verifies the locked VexiiRiscv revision and generates
the fixed HP core below build/; generated RTL is never tracked.
setup_hp_linux.py installs the locked OpenSBI, Linux, and Buildroot revisions
and can resume a checkout left without HEAD by an interrupted fetch.
build_hp_linux.py builds the RV64 lp64d userspace/OpenSBI image set with the repo-owned
external OpenSBI platform. package_hp_boot.py creates the V2 typed LP/HP flash
bundle and its SHA-256/CRC manifest. check_lp_hp_performance.py applies the
measured 2.5x CoreMark/MHz gate.
setup_hp_rtthread.py installs the locked kernel, RV64 bare-metal compiler and
isolated SCons environment. build_hp_rtthread.py stages only the repository BSP
under the variant and records the source/compiler/configuration inputs.
hp_tools.py checks source revisions and RV64 ELF class. run_hp_sim.py keeps
Linux, smoke and RT-Thread logs/verdicts separate and checks every required
workload marker together with a successful process exit.
run_debug_session.py is the local Hazard3 debug acceptance driver. It starts
the Verilator remote-bitbang endpoint, the lock-pinned OpenOCD binary, and
RISC-V GDB, then records their logs and a structured result. Invoke it through
make CONFIG=configs/ci/ihp130-debug.mk SIMU=VERILATOR debug-sim; see
../docs/hazard3-debug.md for its scope and
limitations.
program_xpi_flash.py drives the SRAM-resident XPI loader through an existing
OpenOCD GDB endpoint. It validates and splits a BIN at 4 KiB sector boundaries,
generates a reviewable GDB script, and performs erase/program only when
--execute is explicit. See ../docs/ip/xpi.md.
check_rtl_style.py applies the ownership-aware RTL style rules from
../rtl/rtl_style_manifest.json. The CI
target checks changed self-owned RTL for positional module connections, legacy
constructs, and the staged naming contract. rtl-style-check-all retains the
historical full-tree structural baseline while naming debt is migrated in
module-sized batches. Existing findings must not be expanded by a new change.
migrate_rtl_connections.py is the conservative migration helper for legacy
positional instances. It discovers ANSI-style module declarations in the
production RTL and locked technology/IP trees, rewrites only exact positional
parameter and port lists to named connections, and reports ambiguous instances
without modifying them. Run make rtl-migrate-connections, then
make rtl-format rtl-style-check; review the generated diff before committing.
migrate_rtl_names.py shortens only local identifiers beginning with s_ or
r_ (plus local automatic variables such as read_request). Public module
ports and interface fields are intentionally unchanged. Run
make rtl-migrate-names, then format and lint the resulting diff.
Update or add tests in ../tests for script behavior. Run
ruff check . and python3 -m pytest -q; build-flow changes also require the
relevant dry-run or regression profile from AGENTS.md.
