amdsmi-commit-and-pr-conventions

Use when writing or restructuring git commits or opening/updating a pull request for amd-smi — composing commit titles, commit message bodies, PR titles, or PR descriptions. Defines the Conventional Commits `type(amdsmi):` title convention enforced by the Systems PR Bot, the rocm-systems PR template sections, the unit-test and JIRA/ISSUE-reference gates, brevity caps, and the rule that JIRA tickets appear only in the PR JIRA ID section, never in code comments or commit bodies.

Commit & PR Conventions — amd-smi

The single source of truth for what a commit message and a pull request look like in amd-smi. amdsmi-restructure-commits triggers this skill for message wording; amdsmi-changelog-automation owns CHANGELOG.md entries.

Core principle: Write for an expert who already knows the codebase. Bullets, not prose. State what changed and why — never narrate how the code works.

Title Convention (commits AND PRs)

type(amdsmi): imperative summary

The PR bot (tools/systems_pr_bot) enforces Conventional Commits on PR titles. Use the same form for commit subjects so a single-commit / squash PR auto-titles correctly.

Rule	Value
Type	One of feat, fix, docs, style, refactor, perf, test, build, ci, chore, revert
Scope	(amdsmi) by default; a narrower lowercase scope is fine (fix(cli): …, feat(fabric): …)
Mood	Imperative ("add", "fix", "remove" — not "added"/"fixes"/"fixing")
Length	PR title 10–80 chars (bot limit); keep commit subjects ≤ 72 (git norm, safely under the cap)
Punctuation	No trailing period
Breaking	Append ! before the colon (feat(amdsmi)!: …) for an ABI/behavior break

Good: fix(amdsmi): reject nullptr mode pointer in compute-partition getter Bad: [AMD-SMI] Fixed the partition bug. (legacy tag, past tense, period)

No [AMD-SMI] / [ROCM-NNNNN] tag — the […] form fails the bot's title regex. Ticket references live only in the PR's JIRA ID section (below).

Commit Message Body

type(amdsmi): imperative summary

- Verb-first bullet: what changed and why it was needed
- One bullet per distinct logical change
- Group by file/layer when a commit spans the cascade

Signed-off-by: Full Name <email@amd.com>

Rules:

• Blank line after the subject; wrap body at 72 columns.
• Each bullet starts with a verb (Add, Fix, Remove, Refactor, Implement).
• Include the "why" only when it is not self-evident from the change.
• No JIRA ticket references in the commit body. Reference the code/behavior, not ROCM-NNNNN. Tickets live in the PR's JIRA ID section only.
• No internal labels ("regression guard", sprint names) in the message.
• Signed-off-by is required (git commit -s); preserve original authors and add Co-authored-by: trailers when squashing multiple authors.
• If a single bullet needs a full paragraph to explain, the change is probably too large or the root cause is unclear — stop and reconsider the split.

Pull Request Body

Follow the rocm-systems template (.github/pull_request_template.md) — these exact sections, in order:

Section	Content	Keep it
## Motivation	Why this PR exists, the problem it solves	1-3 sentences
## Technical Details	What changed, grouped by file/layer with bullets	Bulleted, no prose walls
## JIRA ID	JIRA ID: ROCM-NNNNN (or Closes #NNNN for a GitHub issue) — the only place a ticket appears. No links	One line
## Test Plan	How it was verified (commands, hardware)	Bulleted
## Test Result	Outcome of those tests	Brief
## Submission Checklist	The template checkboxes	Leave intact

House style for ## Technical Details (matches the project's best PRs):

## Technical Details

**Header / docs** (`include/amd_smi/amdsmi.h`):
- Corrected the `@retval` list — setter returns `AMDSMI_STATUS_NO_PERM`, not `_PERMISSION`

**Public API** (`src/amd_smi/amd_smi.cc`):
- Getter now rejects a `nullptr` mode pointer with `AMDSMI_STATUS_INVAL`

Rules:

• Bullets, not paragraphs. No ticket numbers outside JIRA ID.
• Assume the reviewer is an amd-smi developer — skip background explanations.
• Don't restate the diff line-by-line; summarize each logical change once.
• Mention the cascade layers touched (header → impl → wrapper → interface → CLI → docs) so reviewers can check coverage.

PR Bot Policy Gate

Every PR to develop is checked by the Systems PR Bot (tools/systems_pr_bot). Two failures add the "Not ready to Review" label and block the PR; the rest are advisory rows in the bot's results comment.

Check	Blocking?	Pass condition
Unit Test	❌ yes	Any changed source file (the amd-smi-relevant set is .c/.cc/.cpp/.h/.hpp/.py/.go/.rs; full list in tools/systems_pr_bot/policy.yml) needs a test_* / *_test.* file in the same PR. Doc/config-only PRs auto-pass
JIRA/ISSUE reference	❌ yes	Description has a JIRA ID: <KEY> / ISSUE ID: <KEY> line, a closing keyword (Closes #N), or a bare #N. A bare Resolves ROCM-NNNNN (no #) does not pass
Title (Conventional Commits)	advisory	type(scope): …, 10–80 chars
Description length	advisory	≥ 30 chars
Forbidden files	advisory	No .pem / .key / .env / .crt / private keys

A source change with no accompanying test is the most common block — pair every code change with a test, or split a docs-only PR out, before opening. Separately, pre-commit is a required CI status check (must be green to merge) but is not part of the bot's label logic above.

Brevity Caps

Symptom	Cap
Comments longer than the code they explain	Explain only a non-obvious root cause; one or two lines max. A paragraph means stop and ask.
PR/commit body reads like a tutorial	Cut anything an amd-smi dev already knows
Comma-separated list of changes	Break into one bullet per item
Ticket number in code or commit	Move it to the PR JIRA ID section

Common Mistakes

Mistake	Fix
Legacy [AMD-SMI] / [ROCM-NNNNN] tag in the title	Conventional Commits type(amdsmi): … (the […] form fails the bot)
Past-tense subject ("Fixed…", "Added…")	Imperative ("fix", "add")
ROCM-NNNNN in commit body or code comment	PR JIRA ID section only
Source change with no test_* / *_test.* file	Add a test in the same PR (bot blocks otherwise)
Resolves ROCM-NNNNN as the only ticket ref	Use JIRA ID: ROCM-NNNNN or Closes #N (bot needs the prefix or #)
Comma-list of changes in body or changelog	One bullet per change
Paragraph-length code comments	One-line root-cause note, or ask
PR body free-form, skipping template sections	Use all six template sections
Skipping -s / dropping a co-author	git commit -s, preserve trailers
