Core Meta Data

Feature Name Description Priority Status Source Owner Due Comments / Bugzilla Links
Investigate New UI For demos, we would like need a reference UI that is not Sato. Investigate possibilities that the Yocto team won\'t need to maintain. OpenBox? Gnome-desktop? GP? LXDE? KDE Mobile? Refresh Sato? 3 Review Meta-data 1.2 Yocto 1.2
selinux patch integration add SE Linux patches in a similar way to PAM 3 Review Meta-data 1.2 Yocto 1.2
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 2 M3, Sprint A eflanagan/Jay7/ka6sox Beth/Jay 1.2 Yocto 1.2, from 1.1

perf scripting\' integration Make it easy and convenient for the user to write and execute \'perf scripts\' from the IDE. We should be able to leverage and build on the Systemtap integration for this. 2 Dev Tom Jessica/Tom 1.2 Yocto 1.2, from 1.1
Package Documentation Audit: All recipes build 31 recipes were identified as not building during the package documentation audit done in M1, Sprint B. Those all need to build and we need to re-run a new package documentation audit. 2 Accept Team Scott G 1.2 Yocto 1.2, from 1.1

QEMU GL Enhancements These include syncing sync qemugl with other projects (e.g. MeeGo?, Android?). Ideally we'd be working on a solution which could be submitted and accepted by upstream QEMU. Also need to consider GLES support. 2 Meta-data Saul (Edwin) 1.2
Implement Factory reset 4 Review Joshua 1.2 http://bugzilla.yoctoproject.org/show_bug.cgi?id=1593
Init Interest in systemd as a replacement for Sys V init is growing but it may not be appropriate for deeply embedded systems. I\'d like to investigate a crop of service based and process monitoring init systems and compare them on a variety of criteria as determined by the community. Furthermore I would like to investigate supporting multiple init systems, the current SysV system, systemd and possibly others. As part of this work, and because increasingly many upstreams support systemd (no doubt thanks to its adoption in Fedora) I would like to investigate implementing some infrastructure which translates from systemd units to the appropriate init format for the supported init systems. 2 Review 1.2

BSPs

Feature Name Description Priority Status Source Owner Due Comments / Bugzilla Links
AMT driver integration incorporate Linux AMT into the Yocto BSPs 1.2 Intel
Zaurusd++ (devmand?) I keep seeing changes to toggle certain features for various boards (audio on the beagleboard, N450 and spring to mind), rather than writing lots of recipes for this perhaps we could resurrect zaurusd and evolve it to reflect the projects original goals as devmand; a daemon to handle hardware quirks across a range of boards and devices. 1.2 Joshua
BSP update/intro determine and integrate / create arch reference BSPs (e500, Cortex, ARM, MIPs) 2 Dev Bruce/Richard/team Bruce 1.2 Yocto 1.2, from 1.1
Drop Grub for Syslinux Grub is considerably more complicated than we need for any of our current BSPs. Syslinux can be used in place of every known usage of Grub. For upcoming EFI BSPs, we can look to Efilinux. This will reduce our bootloader maintenance burden and simplify our images. 2 Review Darren Darren 1.2
Integrate alsa-state Remove all the BSP specific $MACHINE-audio recipes in favor of the more generic alsa-state mechanism in use by OE already. 1 Review Darren 1.2 This possibly conflicts with the item to refresh zaurusd.
Upgrade to EFI Where possible, update our existing BSPs to boot using EFI. This will support development of efilinux as well as help us prepare for the newer boards which will be EFI only. 2 Review Darren Darren 1.2
BSP/kernel wrappers/wizards Create some simple scripts or 'wizards' that make it easy for users to start writing a new BSP and/or easily make simple kernel modifications to a BSP. Ideally, users shouldn't need to know anything low-level about the kernel, git, or the mechanics of appending config items to recipes in order to get a BSP up and running or to make the simple modifications needed to tweak or maintain it. 2 Review tomz tomz 1.2
replace qemuppc Bruce 1.2 Come from bug 414

ADT / Tools and Support

Feature Name Description Priority Status Source Owner Due Comments / Bugzilla Links
Enhance the deploy part in remote debug 2 Review Lianhao Jessica 1.2 http://bugzilla.pokylinux.org/show_bug.cgi?id=1600
Secure login 2 Review ADT Team Jessica 1.2 Yocto 1.2
Linux tools upstream integration There're some activities within the Eclipse Linux Tools community for various tools remote invocation improvement, we need to sync up with the community for their latest deliveries and make some contribution if possible 2 Review ADT Team Jessica 1.2 Yocto 1.2
Add recipe supporting autoconf-nativesdk and automake-nativesdk The new libtool m4 macros(supporting --with-libtool-sysroot) resides in the directory where host aclocal can not find it by default. This requires the user to manually add that directory using -I options. Adding automake(autoconf)-nativesdk into meta-toolchain would help this. 2 Review Lianhao 1.2 Yocto 1.2
Eclipse BSP/Kernel Plugin Provide an Eclipse plugin to facilitate configuring new BSPs and streamlining the linuix-yocto development workflow. 2 Review Darren 1.2
enhance the bitbake commander eclipse plugin By having the Eclipse as a frontend UI to bitbake server, eclipse may talk to bitbake server, enable the user to glimpse on the variables' values when editing the recipes, try out building the recipe being edited, etc. 2 Review Dongxiao/Lianhao TBD TBD This requires new features both in eclipse plugin and bitbake server.
Tracing: tuna, oscilloscope recipes This might be more useful with the increased importance of RT 3 Review from 1.0 1.2 Yocto 1.2
Tracing/profiling HOWTOs Create a document or extend the current Yocto tracing wiki page to explain in detail how to use all the tracing tools in Yocto. It should detail not only how to use each tool individually, but also how to use them in conjunction with each other, highlighting situations in which each is most useful. There should also be some extensive worked examples of real-life use-cases and how they could be investigated using the Yocto tracing/profiling tools. 2 Accept Tom Tom 1.2 Yocto 1.2, from 1.1
Profiling: Valgrind tools in Eclipse 2 Accept Dave/JZ 1.2 http://bugzilla.yoctoproject.org/show_bug.cgi?id=1580
Tracing: Systemtap usability in Yocto 2 Accept Tom Tom 1.2 http://bugzilla.yoctoproject.org/show_bug.cgi?id=1551

Documentation

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 ScottR 1.2 Q3 at the earliest

Fast boot time 2 second boot time target 1 Dev Team Darren 1.2 Yocto 1.2, from 1.1, continuation needed?
Upstream config fragments Work with John Stultz to upstream a Linux kernel config fragment manager and rework the yocto-kernel-tools to use it. This will simplify our tooling and increase our usage/test base. 1 Review Darren 1.2
Real-time process-executed timers Timers currently run at the priority of the softirq that processes them and they are accounted to whichever task was preempted for them to run. This negatively impacts determinism and accounting accuracy. 2 Review Darren 1.2
Define Kernel policy We need to clearly document kernel policy and make the config fragments reflect it. This will facilitate a more modular approach to building BSP kernel configs, as well as make it clear what can be expected to be supported when running a "linux-yocto kernel". 1 Review Darren 1.2
