Poky Features Kernel interactive targets To support incremental kernel development having the ability to run menuconfig (or xconfig, etc) directly is a common request. We'll need to add this for commercialization anyway. i.e. bitbake -c menuconfig. This fuctionality already exists. 1 Done Richard bruceashfield Enhancement

Tool Development and SDK Features oprofileUI Fixing various bugs of the oprofileUI to make it workable on big endian host.(i.e. ppc, mips) 2 Done Jessica lianhao.lu Bug #382 / Bug #493
Poky Feature SDK Version Control If we can expect that yocto SDK has lots of release in the future, we might need to consider SDK version control. Currently, every thing installed under /opt/poky which leads to things be overriden, we need to be able to use a scheme like /opt/poky-1.0, /opt/poky-2.0 to distiguish things. 2 Done Josh jzhang Enhancement

Group Feature Name Description Priority Status Owner Source Comments / Bugzilla Links
Distribution / components Distro Audit: Licence Checksums licence checksums 1 Done Saul rpurdie Hygiene
Poky Features Performance Analysis Completed "I'd like someone to instrument a green release build, see where it spends time (hot/cold parsing time, individual task building time) and then compare this with our 0.9 release build. I'd also like to compare the disk usage between the two. Once we have a blame list we can then set about fixing it. Some things I know will come up: a) pseudo, b) checksums/signature code, c) exec() vs fork for executing tasks, d) task based prebuilds increasing disk usage, e) rpm dependency calculations, f) using rpm vs. ipk but I may be wrong and there may be others. We need numbers. " 1 Done Saul / Qing, Dongxiao rpurdie Enhancement
Poky Features environment variables for kernel builds switching a branch, or adding a configuration feature (and even changing the kernel repo) is often done during development of a BSP. Having some additional variables that are pass the bitbake environment scrub would be useful. i.e. KBRANCH=foo bitbake -c configure linux-yocto. This goes along with the other BSP bootstrapping suggestions. 2 Done Bruce bruceashfield Enhancement
Supported Targets ARM Platform Support Replace beagleboard with Beagleboard XM - decision 2 Done Bruce alex Basic Yocto hardware support
Distribution / components Security Process We need a dedicated person to scan and apply critical security updates to the distro. The MeeGo team already has a similar process with some scripts which may be leveraged. To complete the task, the process should be documented and a first pass over the metadata made to establish the current position on security. Any upgrades needed should be identified and a plan to address them should be in place but doesn't have to be implemented by this point. 1 Done ScottG ktian1 enhancement

Documentation Kernel Framework Paper from WR The paper from WR needs to be re-written and then posted somewhere on the Yocto Project site. This will involve examiniation of the text and re-writing and formatting for presentation. Currently it is simply a text document. Completion time assuming uninterrupted time is one week. High Done Scott Rifenbark 1 Week Documentation
Documentation Poky Reference Manual This guide exists in the 0.9 form. The re-write of the text needs to be completed. So far, all the chapters have been rewritten but not re-posted on the site. Only the appendices remain for a text scrub. Time to complete this would be a week of uninterrupted time. Ideally, the manual would be a sub-manual that would be referenced and architected into the Yocto Project Development Guide. Medium Done Scott Rifenbark 1 Week Documentation

Poky Features Fetcher Overhaul Phase 1 - SRC_REV enhancement
  • a) Add code in FetchData::__init__() which will check if the selected fetcher supports srcrev and the automatically call a function to set the src rev value instead of each fetcher doing this.\n
  • e) Break SRCREVINACTION deadlock. To do this, we need to start using a keyword for automatically increasing SRCREV, e.g. SRCREV = "AUTOINC". The actual revision can be injected into PV using SRCPV. If we do this there should no longer be a need of the deadlock;
  • k) Ensure that we only set __BB_DONT_CACHE when SRCREV = "AUTOREV". This may need a new method call for fetchers to tell whether they're "floating" or locked down.

Distribution / components User specified qemu config support We'll provide user an edit box which allows advanced qemu user to specify arbitrary qemu configuration to meet their needs, which the poky-qemu scrip will just append the config list towards the end of the list of parameters to bring up qemu, it also expect the poky-qemu script to do some basic sanity check on the user specifications to catch the obvious mistake 2 Done Saul / criping criping enhancement, was M2, Sprint E
Tool Development and SDK Features SDK Version Control support in SDK generator installer If we can expect that yocto SDK has lots of release in the future, we might need to consider SDK version control. Currently, if we un-tar the sdk, it will override the older version. It's not good for app developers since they might need the old version to do something. And also, maybe a finer installer than untar is preferred. Installer will tied to certain SDK version and the installation will go under /opt/poky-versionNo. 1 Done Jessica criping Enhancement-expect planning process by Jessica to handle this task. Was M2, Sprint E.

Poky Features Bitbake multi-threaded parsing Bitbake recipe parsing is currently single threaded. I want to make this multithreaded as the speedup would be nice.

Poky Features kernel development layer The (correct) poky behaviour of building known revisions coupled with the fetcher requiring a BSP branch to already be present means that local modifications (and kernel source tree) are required for kernel development. I already have a layer that overrides/modifies the behaviour when added to the bblayers.conf and configured into an environment. This seems useful for more people to use. 2 Done Bruce bruceashfield Enhancement, was M2, Sprint C

Poky Features Poky Image Creator A standalone application you can run which asks you to select a distro and machine, then presents a list of packages you can select. Once the selection is made, it goes off and bakes you an image which is then presented to you. Implementation wise, it should use the sstate packages, be a bitbake UI and use the usual poky bbclass files to do the image construction behind the scenes. 1 Re-plan Joshua rpurdie Enhancement

Poky Features Fetcher Overhaul Phase 2 - API reorg
  • f) Add a generic unpack funciton to __init__.py based on the unpack task in Poky ;
  • g) Split go() methods into the following steps: i) download() - do whatever transfer is necessary to get the sources locally ii) build_mirror_data() - generate any data that would be needed to construct a source mirror iii) unpack() - takes a directory as an argument of where to place extracted sources;

The existing go() methods should be replaced with a set of calls to the above sections of functionality as appropriate in the individual fetchers. Some of these categories of function make no sense in certain fetchers, in which case they shouldn't need to implement them. Functions are only executed if the method is present.

  • h) Change Poky's unpack to call an unpack method in the fetchers.
  • i) Change Poky's fetch task to call a "download" method in the fetcher instead of go().
1 Done Saul / Ke, RP rpurdie Enhancement
Poky Features Fetcher Overhaul Phase 3 - git enhancement
  • j) Optimize git fetcher for the new layout so for a git checkout, we clone the repository in download(), then unpack just does a clone with references to the original repo.
  • k) Ensure that we only set __BB_DONT_CACHE when SRCREV = "AUTOREV". This may need a new method call for fetchers to tell whether they're "floating" or locked down.
  • l) Add a new "BB_NO_NETWORK" variable which the fetchers check before peforming an operation which hits anything remote. This means adding in error messages about why network access is needed at various points (e.g. SRCREV = "AUTOREV" for a given recipe)
  • m) Add multiple branch/srcrev support for git fetcher. These would be of the form: git://somelocation/somerepo.git;name=ref1;branch=foo;name=ref2;branch=bar SRCREV_ref1 = "hash1" SRCREV_ref2 = "hash2" which would ensure both hash1 and hash2 were in the final repo.
  • n) Change git fetcher to default to git protocol instead of rsync
1 Done Saul / Ke, RP rpurdie Enhancement
Poky Features DSO linking changes "By the default the gcc linker will automatically link any dependant objects/libraries. ""Inherited"" linkages can cause issues, for example, where a shared object changes its dependencies but a program has come to rely on symbols from an implicitly linked library. Fedora implemented this change in F13, seems like it would be useful to have in Poky too. " 2 Done Saul / Nitin josh bug#516
Poky Features libtool sysroot option libtool 2.4 has a sysroot option. We should try and use it, see how it works and whether we can ditch some of our libtool hacks. 1 Done Saul / ScottG rpurdie Enhancement
Distribution / components MACHINE or Recipe specific sysroots Each machine should have its own sysroot. We'll probably have to split do_populate_sysroot into a two step process, creation of the package and than installtion of the package, which the installation of the package being made machine specific (put ${MACHINE} into ${STAMP} and bitbake should do that). Also allowing this to work per recipe would be desireable 1 Done Saul / Dongxiao rpurdie Hygiene
Distribution / components Toolchain Bootstrap Process The toolchain as it bootstraps overwrites files like libc.so and libgcc.so in the sysroot directory which causes issues if you just try and rebuild part of the toolchain. Each step of the bootstrap process should use a separate sysroot. Once this is once, sstate file overwriting detection can be added and enabled. 1 Done Saul / Dexuan rpurdie Hygiene
Distribution / components Add headers and libraries to qemu images Since we'll be using qemu images as target sysroot, need to create a set of qemu images for minimal, sato, LSB that contains target header and libraries. 2 Done Saul jzhang Enhancement

Documentation Migration chapter in the Poky Reference Manual This chapter would cover the four identified use-cases for migrating up to the most recent version of Yocto Project. Additionally, it would cover migration scenarios from other development systems. The chapter does not yet exist. The chapter has not been scoped outside of having a meeting that identified four use-cases that did not include migration from a development system outside of Yocto Project. It will take some more scoping time to cover those areas (a day or two). Again, I have no idea of the length.

Poky Features package config option enhancement there're several enhancements we may do here: * allow users setting specific config options (local or global) from external tool, such as poky image creator, instead of changing recipes manually. Need a mechanism to convert from variable assignments into exact config options (e.g. feature_${PN} = ""1"" -> ""--enable-feature""). Consequently dependency chain needs update with option status. * host contamination check. We have swabber to check host contamination, but I'm not sure whether it covers configuration phase. If not, this is one area to improve, as not ususually we see configure script checks host bits for available features * conditional option manipulation. In many recipes we enable/disable one option based on availability of other packages. Now this is done manually and not flexible. this should be made automatically though some new annotation to indicate condition, or just base_contains (not convenient: long line, need define distro features) 2 Review Richard/MarkH ktian1 Enhancement
Media Yocto Project Awareness Video This 2.5 minute video would introduce and describe the benefits of Yocto Project. The video would use entertaining animations that described concepts and benefits. The result would be suitable for YouTube, conferences, and the website. The production is called an "Epipheo" and will be created by Epipheo Studios. The engagement process has begun and the kick-off meeting will be soon. The PO is in place. Time for development is 10 weeks. High Kick-off Imminent Scott Rifenbark 10 Weeks Media
Documentation Yocto Project Debugging Guide This would be a guide for the debugging and bug tracking process in Yocto Project. Originally, the thought was that we needed a Bugzilla User's Manual. However, since we don't own Bugzilla it doesn't make sense to produce documentation for it. Rather, we should document the process as it fits into the Yocto Project environment. Ideally, the manual would be a sub-manual that would be referenced and architected into the Yocto Project Development Guide. The manual has not been scoped and would take a week to scope. Again, I have no idea of the length. See the previous item for standard industry writing estimates for software documenation. Medium Not Started Scott Rifenbark 3-4 Weeks Documentation
Website Yocto Project Website The 0.9 website is in place but needs updates. Items for consideration are the left-panel naviagation scheme, a contributions guidance page, color-scheming and theme (possibly). Medium Not Started Scott Rifenbark 1-2 Weeks Website

Poky Features OpenEmbedded/Bitbake Upstreaming "We firstly need to review where we are and where OE is. We then need to make a plan about what we're going to push upstream and what we're not. I'd suggest when we're in PRC, we do a crash course in ""dealing with OE"" and then many dedicate a block of time (a week) where the distro team comes up with a patch set we then propose and get merged into OE. I'd like to find a couple of interested people to monitor OE more regularly and start a workflow of things between Poky/OE where appropriate. The key thing to remember is we need to keep the architectures compatible. The team is now at the point where I'm happy for them to actually try building OpenEmbedded and not worry about it tainting them! " 2 Review rpurdie Process
Poky Features Handle old versions in WORKDIR an incremental build directory may finally include many old versions WORKDIRS. It'll be good to have those old versions tracked in the cache, which can then either generate a report or allow selectively cleaning up an specific version WORKDIR. Or else it's difficult to figure it out when people want to keep the whole tmp directory but like to cleanup some old bits when disk usage is under pressure. If it's not easy to do in bitbake, perhaps some separate scripts would be also helpful 3 Review ktian1 Enhancement
Poky Features run bitbake w/o rebuilding the cache "sometimes it's useful to allow run bitbake w/o re-parsing recipes, if we know nothing metadata is changed. we can just allow reusing existing persistent cache. this is useful when people is debugging WORKDIR w/o metadata change. also sometimes ""bitbake -e"" is used frequently to check poky variable information. with existing cache, several seconds can be saved which are not negligible for a developer daily working on Yocto " 2 Review ktian1 Enhancement
Poky Features parallel make improvement parallel make experience is not good, especially when bb threads and make threads are increased larger than 8. So far we either try to fix package makefile or mark the recipe as no parallel make, when build faiures are reported. But this greatly impacts user experience for a successfully continuous build process. Could we define a safe number we do want to support for 1.0 release? and then have our autobuilder, QA test, and developers cover that number immediately and fix any issues accordingly. Then the safe number can be suggested to the Yocto user 2 Review ktian1 Enhancement
Poky Features Dependency packages rebuild/clean It is a mechanism to rebulid or clean a package and all other packages which have build/runtime dependency on it. With this change, we can find potential influences of package upgrade to its related packages, which can make the incremental build more trustable. For example, if we upgrade a package to a new vesion which changes its API, this mechanism can easily find out the incompatibility to other packages which have dependency on it. 2 Review dongxiao.xu Enhancement, replaced by checksum feature

Distribution / components Connman-gnome enhancement features Enable connman-gnome to support features like, WPA Enterprise connection, hidden SSID, etc. 3 Review dongxiao.xu enhancement
Distribution / components Java Running Environment support Since most embedded systems support java applications running in it, maybe we'd better consider supporting some kinds of JVMs(Embeded JVM). The JVM may not run by default, but user can launch it if running java applications. Compared with GTK/QT, java user number is not small too. 3 Review criping enhancement
Distribution / components create more use cases UPnP demo is one really good use case showing how Yocto is utilized to make real functionality. and we could create more to show how Yocto is easily adapted to real use cases. Those use cases can be either maintained as seperate demo layers in yocto repo, or in seperate branches for reference. We can also call for community's contribution on this which would make 1.0 full-fledged.

Distribution / components i18n support internationalization is an important system wide feature. Many component like font, locale affect the i18n. Yocto alreay has some i18n related package like pango, but so far did not consider i18n systematically. so this is place holder to systematically add i18n support. 2 Review yuke/qing enhancement
Distribution / components more demos demos are a good way to educate, push the envelope, and at the same time tout the strengths of the platform. This item just records a current set of ideas from various sources which could/should be implemented: * face-recognition/face-finding, * robotic control/application of face-finding to 'camera-as-sensor' (hexbug demo), * others [tbd, add here] 2 Review tzanussi enhancement
Tool Development and SDK Features Yocto Installer support for image-creator and needed yocto-metadata design Come up design what need to be created as packages to support using "opkg install" for image-creator and needed yocto-metadata 2 WIP, pending comments from RP regarding how to packaging metadata Jessica rpurdie Enhancement
Tool Development and SDK Features Yocto Installer image-creator and needed poky-metadata support The poky build system will build packages for image-creator and needed poky-metadata, which the Yocto Installer will be able to use "opkg install" to install them 2 Review Jessica rpurdie Enhancement
Tool Development and SDK Features Provide qemu management UI In current eclipse plugin, QEMU settings are put together with project configuration. So we can only have limited settings. If we can have a separate QEMU management UI, the end user could firstly create a QEMU config, such as (env file of arch, image location, unfs or not, sato or lsb, mem size, disk size). And then he can launch a QEMU with a specific config. The dependency between project configuration and QEMU config will be resolved. After all QEMU has nothing to do project configuration. Need to careful review the UI to ensure minimal impact to testing matrix. 3 Review criping "Enhancement, duplicate of ""Qemu mem/disk size can be adjusted"""

Tool Development and SDK Features Profiling/Trace GUI's We have a wealth of great tracing and profiling tools but the UI's for them are all extremely minimal and usually quite ugly. Would be great if we could compete with, or even better, Apple's offerings here. We have the technology! 2 Review josh "Enhancement, duplicate of ""Tracing/Profiling Planning Complete"""

Tool Development and SDK Features Design next-gen tracing/profiling tools Yocto 1.0 will include all the essential existing tracing/profiling tools expected by users, and Josh has proposed a UI integration of all those tools as far as it's possible to do so. That level of integration, basically a 'plugin-level' integration is necessary and useful, but doesn't go far enough. A next-generation tracing tool would integrate at a much more fundamental level; if done properly, it would provide unmatched levels of power and usability to users, and would allow Yocto to distinguish itself in the embedded tracing/profiling space in a way also unmatched by any other distro/build-tool. The implementation would of course not be available for Yocto 1.0, but a coherent design, including prototypes, that could be taken to the community and implemented in a V 1.5 or 2.0 should be done in that time frame. 1 Review tzanussi "Enhancement, duplicate of ""Tracing/Profiling Planning Complete"""
Documentation Features Self Documentation of image contents "I'd like to see the -doc packages Poky builds being combined into some kind of large documentation index representing the collective API docs of the target being built. This can then be placed on a webserver and viewed over the web. We'd have a demonstration of this for a ""bitbake world"" target. Part of the idea here is to start making good use of the docs as if developers see this they might start writing better docs too. Aim is to lead the field :). There are a number of places poky packages disable doc generation due to missing tools so we'd need to add these so we can enable the doc generation. Many packages already have many docs though too.

Validation Testing Framework Add a framework for doing automated testing in the project 1 Review davest project commitment
Validation more SDK builds on autobuilder enable more SDK related tests on autobuilder such as meta-ide-support, etc. 2 Review ktian1 project commitment, addressed by test plan (?)
Validation more people should try using SDK this may not be a feature, but a requirement. SDK including meta-toolchain is one key factor impacting user experience on Yocto. It's not enough to have only SDK team play with it 2 Review ktian1 project commitment, addressed by test plan (?)
