Potential Yocto 1.1 Features

Yocto 1.1 - Target release = October 2011

This page contains a list of Yocto 1.1 features. In early March, the Yocto Architect will issue an official call for Yocto 1.1 features. This list contains reprioritized items from 1.0 or features that came up as a result of discussions among Yocto engineers. If you have a feature you would like to see added, send an email to the Yocto Architect with a description of the feature, its impat on the source code, and whether you are willing to help write the code to implement the feature. The Yocto Architect will add this to the potential Yocto 1.1 Features list. The potential Yocto 1.1 Features list will be turned into the Yocto Features List as described in the Program Management Plan.


Yocto 1.1 Themes

The topics below are the themes that some members of the team have started brainstorming for Yocto 1.1. These will grow and change with community input.

Yocto 1.1 Objectives

The objectives of the Yocto 1.1 release are to grow participation in Yocto and increase the number of BSPs written for Yocto and partner products based on Yocto.

Yocto 1.1 Theme List

The Yocto 1.1 Themes towards the Objectives listed above are:

  • Multilibs & OE-core config - This work, which began in Yocto 1.0, needs to be completed.
  • Improve ease of BSP creation - Document the lifecycle and process. Possibly create walkthroughs or tutorials to integrate a new board into the linux-yocto kernel.
  • Build performance – Get to the goal of 1 hour build time on a developer machine.
  • Upstreaming – Submit patches to upstream projects in order to reduce the 2,000+ patches which are currently part of Yocto Project.

Process for Entering New Feature Requests

  • Create a new entry in the appropriate feature table below (Poky, SDK, Hardware)
    • Suggestion: start by copying an existing request as a template
  • Give the feature a short, descriptive name
  • Provide a one or two sentence brief description of the feature
  • Set the priority as appropriate (see the legend below)
  • Set the Status to "Review"
  • In the Source field, enter your name along with the origination of the request (e.g. OSV, OEM, Community) if applicable; provide as much detail here as you can
  • In the Comments / Bugzilla field, provide any additional information for the request, such as a link to a bugzilla entry
  • Preview your Entry to make sure it looks ok and then save it

Legend

Priority: 1 = Must Have, 2 = Nice to Have, 3 = Optional

Status: Accept = Engineering agreement to include in release, Review = Under Review for Inclusion in this release, Reject = Will not be included in this release

QA Items

Feature Name Description Priority Status Source Comments / Bugzilla Links
QA Framework Enhancements
  • Add test for unfs_qemu bootup in the sanity test framework and give Liping his patch (Jiajun)
  • Help to define long-term flexible framework for SDK/meta-toolchain testing.. Under the test folder, we have different groups of test, such as sanity, SDK(tools), meta-toolchain. User could freely select which test cases they want to test. (Control granularity/level group? Or even a single case has a switch) (Jiajun)
  • More test-projects into existing manual test part for meta-toolchain. We should help to find the two typical projects, one c and o C++. (Jiajun)
  • Transform the meta-toolchain manual testing into the unified test-framework. (Liping)
  • Prepare a workable environment for testing all those newly added features. (Liping)
  • After sanity test framework is in the upstream, collect data when selecting different kinds of test components. (MeiLei)

Documentation

Feature Name Description Priority Status Source Comments / Bugzilla Links
Package Documentation Audit Make changes defined in the package documentation audit from Yocto 1.0 2 Review from 1.0 Owner = Saul
Yocto Project Development Guide This manual would be an over-arching document that frames the complete development cycle within Yocto Project. The idea here is that the document would be an umbrella document that spawned and referenced subsequent documents. The organization would be the first chapter overviewing the major development pieces such as recipe creation, building, debugging, publishing, fail-safing, back-door hook creation, etc. Scoping would be about two weeks and length would probably be about 40 pages. Overall development time would likely be a month of uniterruped time. 2 Review from 1.0

Build

This section contains requirements related to the build (autobuilder activities, performance, footprint, etc.)

Feature Name Description Priority Status Source Comments / Bugzilla Links
Autobuilder maintenance Bring scripts into configuration or get git repo working for those that can't be brought in. 1 Review Beth M1; Owner = Beth
Meta targets Part of the challenge of autobuilder is that you have to go into autobuilder, edit script, reconfigure, to change just one build target. This is error prone. What we need is a meta-target where Beth can say she wants to build Poky-image-sato for QEMU x86 and have it just do that. Beth thinks this is done via an override to the web page. (takes ~2 weeks) 1 Review Beth M2; Owner = Beth
License tracking Get common licenses for all packages. (takes ~3 days) 1 Review Beth M1; Owner = Beth
License history Build a parser to do license history more gracefully and make sure all recipes are correct. (takes ~2 weeks) 1 Review Beth M2; Owner = Beth
Audotbuilder infrastructure Bring up additional autobuilders and work with sysadmin to configure. 1 Review Beth M2; Owner = Beth
Overall Project Host a retrospective to discuss what went well and what can be improved in Yocto 1.0. 1 Review Beth M1; Owner = Beth
Release Scripts Create Release Scripts for OCT 2011 release. 1 Review Beth M3; Owner = Beth
Enhanced Performance Also, environmental requirements/suggestions for expected performance; Goal is to build in under 1 hour 2 Review from 1.0
Disk Space Reduction 2 Review Team
Share gcc work directories 2 Review Team
Patch Test System Create a machine where developers can upload/test patches before submitting them to master to ensure builds won't break when patches are added. 2 Review Team
build statistics reporting As someone interested in how long it takes to build different images on different hardware configurations and other assorted build metrics, I would like a web based service, that takes output generated by an extended buildstats.bbclass and stores it, to compare against different machines. The end result should be a way to visualize the collected data. See: https://wiki.yoctoproject.org/wiki/Yocto_Buildbot_Autobuilder_Discussions Review eflanagan/Jay7/ka6sox
