1____ 2# Design Guidelines - *Delete this section* 3 4* Not all new features need a design document. If a feature can be 5 contributed in a single reasonably small patchset that has little impact 6 to any other areas, it doesn't need a design discussion and documentation. 7* The focus of the design is to define the problem we need to solve and how it 8 will be implemented. 9* This is not intended to be extensive documentation for a new feature. 10* You should get your design reviewed and merged before writing your code. 11 However you are free to prototype the implementation, but remember that 12 you may learn of new requirements during the design review process that 13 could result in a very different solution. 14* Your spec should be in Markdown format, like this template. 15* Please wrap text at 79 columns. 16* Please do not delete any of the sections in this template. If you have 17 nothing to say for a whole section, just write: None 18* To view your .md file, see: https://stackedit.io/ 19* If you would like to provide a diagram with your spec, ASCII diagrams are 20 required. http://asciiflow.com/ is a very nice tool to assist with making 21 ASCII diagrams. Plain text will allow the review to proceed without 22 having to look at additional files which can not be viewed in Gerrit. It 23 will also allow inline feedback on the diagram itself. 24____ 25 26# Example design - this is the design title 27 28Author: 29 < Name and IRC nic > 30 31Primary assignee: 32 < Name and/or IRC nic or None > 33 34Other contributors: 35 < Name and/or IRC nic or None > 36 37Created: 38 < Date initially created, revisions in will be tracked in Gerrit > 39 40## Problem Description 41(1 paragraph) What are we doing and why? What problem are you trying to 42solve? What are the goals and NON-goals? Please make the objective 43understandable for someone unfamiliar with this project by including the 44necessary context, but keep it short. Elaborate on the details below in the 45Background and Requirements sections. 46 47## Background and References 48(1-2 paragraphs) What background context is necessary? You should mention 49related work inside and outside of OpenBMC. What other Open Source projects 50are trying to solve similar problems? Try to use links or references to 51external sources (other docs or Wikipedia), rather than writing your own 52explanations. Please include document titles so they can be found when links 53go bad. Include a glossary if necessary. Note: this is background; do not 54write about your design, specific requirements details, or ideas to solve 55problems here. 56 57## Requirements 58(2-5 paragraphs) What are the constraints for the problem you are trying to 59solve? Who are the users of this solution? What is required to be produced? 60What is the scope of this effort? Your job here is to quickly educate others 61about the details you know about the problem space, so they can help review 62your implementation. Roughly estimate relevant details. How big is the data? 63What are the transaction rates? Bandwidth? 64 65## Proposed Design 66(2-5 paragraphs) A short and sweet overview of your implementation ideas. If 67you have alternative solutions to a problem, list them concisely in a bullet 68list. This should not contain every detail of your implementation, and do 69not include code. Use a diagram when necessary. Cover major structural 70elements in a very succinct manner. Which technologies will you use? What 71new components will you write? What technologies will you use to write them? 72 73## Alternatives Considered 74(2 paragraphs) Include alternate design ideas here which you are leaning away 75from. Elaborate on why a design was considered and why the idea was rejected. 76Show that you did an extensive survey about the state of the art. Compares 77your proposal's features & limitations to existing or similar solutions. 78 79## Impacts 80API impact? Security impact? Documentation impact? Performance impact? 81Developer impact? Upgradability impact? 82 83## Testing 84How will this be tested? How will this feature impact CI testing? 85
