Cosim Build

Build gem5 and QEMU for cosim through scripts/cosim_build.sh. This script is the single source of truth for compilation, metadata, and incremental skip behavior.

Quickstart

bash scripts/cosim_build.sh gem5
bash scripts/cosim_build.sh qemu
bash scripts/cosim_build.sh all
bash scripts/cosim_build.sh gem5 --force

For an isolated gem5 worktree:

GEM5_DIR=/abs/path/to/gem5-worktree bash scripts/cosim_build.sh gem5

When testing that worktree, pass the matching binary explicitly:

--gem5-bin /abs/path/to/gem5-worktree/build/VEGA_X86/gem5.opt

Required Policy

Read references/build-policy-and-provenance.md before deciding whether to rebuild, accepting binary evidence, using a nonstandard binary, or responding to stale metadata.

Read references/worktree-incremental-build.md before creating an isolated worktree, copying build outputs, removing an artifact worktree, or accepting evidence from a nonstandard gem5 worktree.

Do not run raw docker run ... scons, direct scons, or make -C qemu/build commands as substitutes for the build script.

Binary Locations

Component	Binary
gem5	`gem5/build/VEGA_X86/gem5.opt`
QEMU	`qemu/build/qemu-system-x86_64`

The build script creates the Docker image from scripts/Dockerfile.run when it is missing.

Integration

cosim-gpu-flow-plan records source bases before build evidence matters.
cosim-gpu-test and cosim-gpu-debug check provenance before launch.
After any rebuild, all earlier test evidence is stale for current source until rerun with the intended binary.

Verification

bash scripts/cosim_build.sh gem5
cat gem5/build/VEGA_X86/.cosim-build-meta
bash scripts/cosim_build.sh gem5

The second run should report that gem5 is up to date and skip rebuilding.

cosim-gpu-debug

gevico/cosim-gpu-skills

Use as the main entry for cosim debugging: gem5 crashes, assertions, hangs, timeouts, address translation faults, non-PASS test results, guest-side waits, and QEMU exits that may be secondary to gem5. Collect logs, preserve live state when needed, route to gem5 model references, and decide the first failing component.

cosim-gpu-codex-review

gevico/cosim-gpu-skills

Use when delegating independent code review, design review, or focused bug investigation to an AI reviewer. Provides delegation templates and records reviewer evidence; higher-level review flow remains in cosim-gpu-review or cosim-gpu-rlcr-loop.

2026-07-071

cosim-gpu-disk-image-edit

gevico/cosim-gpu-skills

Use when the guest disk image needs modification without a full rebuild. Mount with guestmount, add files, systemd services, kernel module config.

2026-07-071

cosim-gpu-flow-plan

gevico/cosim-gpu-skills

Use as the first step for non-trivial cosim testing, debugging, review, or iterative implementation tasks. Do not use for ordinary repository maintenance such as commit splitting, submodule pointer updates, author config, or documentation-only cleanup.

2026-07-071

cosim-gpu-guest

gevico/cosim-gpu-skills

Use when you need to send commands to a running cosim guest. Console pipe interaction, 9p share mount, GPU status check, manual driver load.

2026-07-071

cosim-gpu-info-gathering

gevico/cosim-gpu-skills

Use when collecting, summarizing, auditing, or comparing cosim evidence from artifact directories, large logs, matrices, verdict files, build provenance, or prior conversation records; also use when reducing raw log reads or checking whether existing artifacts lose information. Enforces full raw evidence preservation, bounded reads, source attribution, compact tables, raw-read plans, coverage self-reporting, and unknown-event preservation before analysis.
