The document presents an overview of the development of MeeGo on the Pandaboard, highlighting the collaborative efforts of a small focused team amid various challenges faced, particularly in achieving upstream support. Key points include the need for community involvement, the technological hurdles encountered, and the ongoing status of both upstream and private versions of MeeGo. Future directions include enhancements in UI, multimedia playback, and potentially transitioning to new development platforms.
MeeGo on OMAP4 PandaBoard
- 1. Presented by: MeeGo on OMAP4 PandaBoard Nishanth Menon nm@ti.com Irc Nick: NishanthMenon 20101129
- 2. Agenda ● MeeGo and PandaBoard – was it easy? ● Challenges Faced ● Directions Taken ● Current Status and future directions ● Short Preview
- 3. MeeGo and PandaBoard Was it easy? ● Big upstream focused Team ● TI world wide development – Dallas, Mexico, India, France, .... ● Development for Ubuntu, Android, Angstrom,..... ● Small MeeGo focused Team ● 4-5 members from India, Dallas, Mexico ● Does not really need huge investment to enable if upstream focused ● Decision early on to be a community focused platform – hardware and software :) - PandaBoard was a blessing! ● Thank you MeeGo community – our experience was good!
- 4. Challenges faced 1/2 ● Big Corporations do not move fast enough for upstream – TI inclusive ● Inhouse code is easier to do than upstream – you just need your platform to work! Upstream is compromise, better quality and harder to achieve ● Meaning of upstream varies ● Some folks call upstream == “submitted to ML”!! ● Upstream is not very predictable – A manager's worst nightmare: put a schedule around upstreamed features! ● Features in upstream may not be as fancy and usable as “private code” versions!
- 5. Challenges faced 2/2 ● Surprise: Kernel upstream support for display and EHCI was not ready! No display == no UI! ● MeeGo is constantly evolving – kernel(2.6.35) Vs kernel- dev(2.6.37-rc1) – TI upstream leverage ● New platforms on a brand new OS has surprises as well: ● Mic2 and libgparted story – boot sector formatting for mmc cards! ● -show-cursor option in apps – developers did not really think for handset UI to be used with a mouse and keyboard ● Etc.. ● More importantly – putting Symbian and Android developers into MeeGo development – world of difference – for the better :)
- 6. Decisions made in PandaBoard MeeGo● Team split into two: ● Upstream is more important – TI team split into long term objective of upstream version of MeeGo on PandaBoard. Agenda: – Work with development teams inside TI to identify components that are critical to upstream and force the issue to take place – realities of a corporate world. – Work with the community to help enable features using upstream components – upstream should mean more beyond “nice looking code”! ● Private-demo – showcase what TI internal code can do with MeeGo (TI internal code based on 2.6.35 helps) ●
- 7. Current Status and directions: Upstream version ● Basic shell prompt – all using upstream versions ● Focus kernel ● EHCI support posted to appropriate ML – expected to make 2.6.38-rc1 ● Display support over DVI – framework patches posted upstream – hopefully by 2.6.38-rc1 – few more follow on upstream patches required ● WLAN – to be worked on ● Focus gstreamer/mm: ● Gstreamer 0.11 support patches in the works – but long term ● Short team 0.10 support needs to be worked out. ● Focus UI: ● Enable IVI, netbook? ● Enable SGX ● Focus Build: move to IMG/BOSS
- 8. Current Status and directions: TI private version ● Full UI up with HDMI– basic apps work, network works ● Future directions: ● SGX enablement ● MM playback capability ● Wlan security access points ● Pulseaudio integration ● Maybe modem integration?? ● Even probably switch to Blaze development platform
