A performance tracker for XiangShan

After XiangShan#5635, we have uploaded all IPC data generated by Performance Test CI to GitHub artifacts. So external scripts can fetch the data easily.

This repo is inspired by Verilator RTLMeter, and utilizes artifacts mentioned above.

This use a GitHub Action to fetch data daily and commit .json files to this repo. The frontend is built with Vue 3 + TypeScript + Chart.js.

Go to https://ngc7331.github.io/XiangShan-Dashboard/ to use the dashboard.

Data Layout

Data is separated by domain under data:

data/
	test/ # Performance Test workflow
		branch.json
		<branch>/
			data.json
			<commit>.json

Schema constraints:

• branch.json: list of branch name strings.
• data.json: { "data": { run_id: { "hash", "title", "date" } } }.
• <commit>.json / <date>.json: { benchmark: { metric } }.
• run_id: numeric string.
• metric key: ipc or score.
• metric value: float number.
