Potential Yocto Project 2011.10 Features

Yocto Project 2011.10 (a.k.a. Yocto Project 1.1) - Target release = October 2011

Yocto Project 2011.10 Themes

The topics below are the themes that some members of the team have started brainstorming for Yocto Project 2011.10. These will grow and change with community input.

Yocto Project 2011.10 Objectives

The objectives of the Yocto 2011.10 release are to grow participation in Yocto and increase the number of BSPs written for Yocto and partner products based on Yocto.

Yocto Project 2011.10 Theme List

The Yocto Project 2011.10 Themes towards the Objectives listed above are:

  • Multilibs & OE-core config - This work, which began in Yocto Project 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)

Systemtap integration Make it easy and convenient for the user to write and execute Systemtap scripts from the IDE. http://www.eclipse.org/linuxtools/projectPages/systemtap/ might provide a good starting point and may be something we can contribute to. We may also need to contribute further up the chain to provide e.g. remote target capabilities. 2 Review Tom

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 overviews the major development pieces such as recipe creation, building, debugging, publishing, fail-safing, back-door hook creation, etc. This manual will also include migration information. Scoping would be about two weeks and length would probably be about 40 pages. Overall development time will likely take up to the release given my experience on the creation of the ADT manual (there is no uniterruped time). 1 Not Started from scratch Owner = ScottR
Various Demo Videos The idea here is to create screen-capture type tutorials similar to what exists for the ADT Eclipse Plug-in. However, we want to contract out some help for professional voice-over talent to be used with the images. These don't have to be limited to screen-capture material but could include well-done PPT decks - similar to how other business units in Intel create various training modules. For 1.1 it would be good to capture the script for the existing ADT Eclipse Plug-in module and have it voiced over. Also, for 1.1 it would be good to create a similar module for the Image Creator application. 2 Not Started From ADT module and scratch Owner = ScottR
Open-source Newbie Information This information will be for developers new to open-source. These people do not know what IRC means. Targeted for developers coming from a non-open-source environment. I think the best place for this information would be the website. I haven't looked yet but I suspect information already exists on the web. For Yocto it will be a matter of collecting the best and most useful information, orginizing it and properly referencing/leveraging it. 2 Not Started From scratch Owner = ScottR
Tarball Doc process Right now tarball docs are frozen shortly before a release. The tarball never gets updated beyond that during subsequent documentation development. However, website docs are periodically updated as changes are made during the next development cycle. We need a documentation process where the tarball docs are updated along with the website docs. Perhaps releasing and building a separate documentation tarball is an answer... This whole scheme needs thought about and something implemented. 3 Not Started From scratch Owner = ScottR
OOB documentation Create an out of box guide for giveaway systems built using Yocto. 1 Review Julie Owner = ScottR

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 and consolidate base file licenses. (takes ~3 days) 1 Review Beth M1; Owner = Beth
License tracking Build a parser to do license tracking 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 that can be used for both a weekly release and for OCT 2011 release to be run by autobuilder 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
BSP builds Autobuilder git fetcher improvements 2 Review from 1.0 M1; Owner = Beth
Implement Continuous Autobuilds Build constantly instead of daily 2 Review from 1.0 M1; Owner = Beth

Performance and Usability

This section contains general Yocto performance as well as usability items.

Feature Name Description Priority Status Source Comments / Bugzilla Links
Fast boot time 2 second boot time target 1 Review Team M2; Owner = Darren
Build Yocto behind firewall Darren will investigate site.conf and documentation 2 Review Dave
Minimal Image unique make minimal image smaller 3 Review Team
POSIX support address POSIX failures found in 1.1 2 Review Team

Kernel

This section contains items specific to the Yocto kernel.

Feature Name Description Priority Status Source Comments / Bugzilla Links
BSP kernel config audit Audit kernel configs for the various BSPS. Should not be limited to just kernel config options -- it should also include discussion of overall strategies for defining and managing base branches, feature topic branches, config features, etc, and should result in not only the current kernels being changed to match, but also BKMs being published somewhere, probably in the kernel manual. 2 Review Team
Ongoing kernel maintenance There should be a task spread out over the whole release, say 10% of one person's time (just a guess), for monitoring LKML and Linus' master branch, and/or relevant lists for patches relevant to the BSPs we maintain. We also need to figure out if Bruce needs help with the management of the base branches e.g. re-enabling features after kernel uprevs, moving feature tags forward, etc. 2 Review Tom
Tracing: perf trace scripting support we think usability is the direction to focus on, we want to improve usability through documentation 2 Review from 1.0
Tracing: Add Systemtap support for userspace tracing Add utrace, etc 2 Review Tom
Tracing: Systemtap usability in Yocto Right now, there are instructions on the wiki on how to configure and use Systemtap with Yocto. While straightforward, they are tedious and unlikely to be useful to most people pressed for time. We need to make it easier to use - in addition to documentation/tutorials listed elsewhere, we need to make it usable 'out of the box' (i.e. outside of ADT) e.g. all paths and configuration handled via script or something similar 2 Review Tom
Tracing: tuna, oscilloscope recipes catch up with Tom, likely to remove 3 Review from 1.0
