1. Arago Project Creating an Open Integration and Distribution System William Mills 2009-09-03 http://www.arago-project.org

2. TI Information – Selective Disclosure Arago project Open build, integration, test and delivery platform for embedded Linux on OMAP™ and DaVinci™ processors –Open build: See how we built for our tests and distribution –Open integration: Allow visibility to incremental progress, not just big band releases –Open test: See how we tested, run your own regression test after your changes Standards based & community friendly –Uses OpenEmbedded as a base –Beagleboard.org community also uses OE –Some commercial Linux vendors using or planning to use OE Mentor Graphics (formerly Embedded Alley) MontaVista Linux 6 RidgeRun helped start Arago project Pre-cooked with a Public “Recipe” –Good starting point as it is pre-tested –Expandable and/or customizable

3. TI Information – Selective Disclosure Arago goals Allow TI to build and test the Linux distribution that will be delivered to customers Allow customers to use the pre-built distribution or to rebuild it from scratch the same way we have done Allow customers to run many of the same tests we run Allow customers to extend and customize the distribution to create their end product Allow customers and community members to contribute to the distribution and test assets Allow TI to practice continuous integration of all delivered software for the platform Allow customers to choose their methods of engagement: either official releases only or early access to the evolving baseline

6. TI Information – Selective Disclosure Arago status Not really ready for public use Building process is publicly visible (http://arago- project.org/) Currently being used for –Building filesystem image for OMAP35x PSP and DVSDK –Building PSP release for DM355 and soon DM365 –Supporting trial customers for custom DVSDK work –Will continue to be used to create existing PSP & DVSDKs as a proving ground

7. TI Information – Selective Disclosure Customer Deliverables Images –Full filesystem images that can be used to load the EVM –Customer need not know about Arago Pre-built Packages –Can be added or deleted to filesystem at runtime SDK –Contains libraries, API header files, XDC metadata –Used as building block for customer to build application without using Arago Rebuildable –Contains Arago infrastructure and recipes for components –Copy of all downloaded source Arago Release

8. TI Information – Selective Disclosure Implementation Layers BOM (Bill of Material) –Master layer: specifies all other layers –Also specifies versions of components for a release/platform –Multiple BOM version and stream exist –Examples: Latest baseline, stable release Custom –Customers/TI groups can override lower layer configuration and add their components –For example, a customer can point to their own version of a component to build the application –Include examples for custom file system image, custom board, etc. Arago –Bitbake recipes specific to Arago –Package support classes –Arago stock images OE (Open Embedded) –Snapshot of OE recipies Custom BOM OE Arago

9. TI Information – Selective Disclosure Package Support Classification CoreKey TI Content, TI will address customer issues (Fixes in next versions) ExtraNeeded to demonstrate core Will fix integration issues Will not fix upstream issues ExperimentalBuilds and some functionality OK May have issues May not be in later release Include two sub classes: pre-built buildable UnknownEverything else that is present in OE Not built or tested in Arago

10. TI Information – Selective Disclosure Arago roadmap End of Year (Goal) –Ready for broader use –Will include current PSP and DVSDK release functionality –Will have some automated regression testing in place –Will have much increased ease of use –Description of user installable test frame 2010: –Expand scope of user space –Continuous expansion of automated testing –Expansion of user space packages –Additional usability improvements –Support development for individual packages –Stop releasing existing PSP & DVSDK (?)

12. TI Information – Selective Disclosure Consumer View: Releases Have Quarterly Arago platform releases –Released as tarballs or iso via TI software downloads –Completely reproducible using public resources Arago & other version control archives TI software downloads for items w/o public VC –One release for all platforms –Best support available for each platform New platforms may only have “PSP” functionality or even PSP alpha functionality –Best testing we can offer Manual and Automated testing done –Red / Yellow / Green status reports Per package for each board Per kernel feature for each board (like wiki today) Per Codec or Media type profile for each board (like GStreamer today –Performance reports

13. TI Information – Selective Disclosure Consumer View: Baseline Each Week the current Baseline is rebuilt –All content for a release is created Packages, images, documents, automated performance and functionality reports Manual testing is not done weekly (***) Customers that need more recent fixes can use these baseline snapshots. One of these weekly baselines will be promoted as the quarterly release –Baseline updates may get more conservative and/or more frequent as the release gets near –No “extra work” done to release. –Release testing should start N (4?) weeks before target date *** Spot checking of Manual test may be needed periodically to avoid finding latent bugs at quarterly release time

14. TI Information – Selective Disclosure Developer / Integrator View Need to expand to continuous integration platform Need nightly builds of –Baseline-next All components purposed for next baseline –Progressive “Internal team” version of each component Look for breaks ahead of time This should break often or we are probably not being aggressive enough –Component builds For each component –Baseline + progressive of focused component

15. TI Information – Selective Disclosure Functional Areas Infrastructure –OE packages, Arago build & customizations –Host tools and toolchain Core –Kernel, u-boot, low-level boot code –Link, CE, DMAI, GStreamer –3D accelerator libraries –WiLink Drivers Extra –Base file system –DirectFB, X11, Experimental –Gtk+/X, Qt/X, Qt/Embed, Xfce Desktop
