Proposal: AI-Based Code Review for DPDK

[Jerin Jacob]

Goals
-------

# Leverage modern AI-powered code review tools to accelerate and supplement human review efforts.
# Prevent AI-generated comments from cluttering the mailing list or polluting the main DPDK GitHub repository.

Setup
-------

# Create a dedicated repository:
Set up a new repository, for example: https://github.com/DPDK/dpdk-ai-code-review, under the official DPDK GitHub organization.
This ensures that AI-generated pull requests do not interfere with the main repository (https://github.com/DPDK/dpdk).

# Select an AI review tool:
Use a free, open-source-friendly AI code review service.
One potential candidate is Sourcery: https://sourcery.ai/pricing

# Connect the tool:
Integrate Sourcery with the new repository via: https://app.sourcery.ai/?product=prod_opensource

# Trigger AI reviews:
Once integrated, any pull request to this repository will automatically trigger a code review by the AI tool.
Example of a test PR reviewed by the AI bot:
https://github.com/MarvellEmbeddedProcessors/dao/pull/2

Workflow
-------------

# When a patch is sent to the DPDK mailing list, a bot will convert it into a GitHub pull request on the dpdk-ai-code-review repository.
# The AI tool will review the pull request and leave comments directly on the PR.
# Once the AI review is complete, the bot will close the PR and share the PR URL:
- As a comment in Patchwork URL for the given patch
- With the patch author directly.
# The author can review the AI-generated comments by visiting the PR URL, if they choose to do so.
