You all have items to complete below, please follow up


ARs:
AR: Saul - set up readiness review
AR: Darren - demo use case notes to ScottR
AR: Kevin - do we need to retain the WR copyrights on the kernel doc? or can we rebrand as LF?
AR: Saul - ask Nitin to investigate delta with the MeeGo toolchain

Giveaway:


Sprint B (Due: Oct 01, Midnight PDT)


* demo

** Alex will put the hardware bits together, Darren to write down the description of what needs to come together and wiki-fy it. RP suggests that maybe getting all the pieces running on one hardware might be a good way to try it out just in case.

** create and document on Yocto Linux website the use cases

** NAS: NFS (Mark)
Will do by end of his day today. This will run on MIPS RouterStation Pro
Mark will bring this board and drive to Cambridge

** DNLA Server (Darren)

** UPnP Renderer (Josh)
Will test with real hardware because audio on qemux86 isn't working

* autobuilder runtime testing of images (ScottG)
Will defer this change until release bits are safely out the door


Sprint C (Due: Oct 8, Midnight PDT)

* Go through each of the recipe file summary info and make sure they are there and correct, load all into a spreadsheet (Distro team) tech writer correct them and send them back (MarkH, Bug 281)
Tech writer info pending, may move to 1.0

* add class for rpmbuild (JeffP)
WIP

* ldat compatibility
** importing packages from LDAT (JeffP)
WIP

* determine way to distribute SDK (Jessica)
Done, waiting for the build to push it.

* setup and test RPM feed (Saul)
done


Sprint D (Due: Oct 15 (note: Thursday), Midnight PDT)

** shrink kernel repo size (Bruce)

* demo
** kit up boards for give away (Dave/Saul)

** ensure sato desktop runs on ppc real h/w (Bruce)

I can try getting everything running on one machine too - would it make
sense to try that all on e.g. emenlow, or all on a laptop using qemu, or
both?

Yes, so what I need is something like:

- description
- expected behaviour
- hardware used
- how to build and install the software

... for all four boards. The sooner we have something, the sooner I can start.

Does that make sense, Darren?

Darren (or someone else can correct me.. but what I'm doing now)

Board: RouterStationPro
Purpose: NAS and boot server for other board
Features:
- Contains file server for multimedia and other files
- Can serve files via:
- NFS
- http
- tftp (likely needed if the other boards need to network boot)
- ftp (maybe)
- Will act as THE authoritation DHCP server for the network of boards
- no DNS on the network (is it needed?)

Software:
- From the meta-demo, build the poky-image-nas with the machine target of the routerstationpro (thats the goal, but there might be some custom config files in the end.. still working on it)

I'd go with emenlow since it has working sound. We've never supported
sound under qemu.

Everything on One machine doesn't make a lot of sense to me, for two reasons:

1) This is heavily network dependent, making sure the machines can find eachother is a critical aspect of testing this.
2) Qemu does some magic with tun/tap devices, you have to configure things to get multicast working between guests. I've tested the mediatomb image in qemu, it works. We need to test on real hardware.
3) We don't an image that will install everything on the same machine, and making one doesn't make a lot of sense to me.
4) Running a NAS to serve up media to itself doesn't test the networking side of things as well.

I'd rather use 3 real devices (even if they are all emenlow or blacksand) rather than qemu or all on one.

I thought the plan was to do BOTH a QEMU demo and a demo on real
hardware? If that's not the plan, it should be the plan.

Features:
- Contains file server for multimedia and other files
- Can serve files via:
- NFS
- http
http isn't needed. (the DLNA server will mount the files over NFS into its filesystem and Mediatomb runs it's own http server on a special port to server up the files to the media renderers).

- tftp (likely needed if the other boards need to network boot)
- ftp (maybe)
No need.

- Will act as THE authoritation DHCP server for the network of boards
- no DNS on the network (is it needed?)
No DNS needed, runs over multicast, and we can specify the NFS server with a dotted quad.


Software:
- From the meta-demo, build the poky-image-nas with the machine target of the
routerstationpro (thats the goal, but there might be some custom config files
in the end.. still working on it)
Perfect. Looks good Mark.

There has been no discussion of a QEMU demo for the media network demo. I've tested some components with QEMU, but we aren't currently planning on demo'ing this in QEMU.

Yeah, it doesn't make sense as a demo per se, but for the folks who only
have one system, to get it all going. Another motivition I thought was
to have 'something' as a worst-case fallback, e.g. with all the 'moving
pieces' Dave is worried about.

Actually, it could make a little bit of sense to have a single
nas-mediatomb-xxxclient image, pointing to each other on localhost, that
could be easily tweaked in the field and swapped in/out as any one of
the components - just a thought and probably not worth it at this point.

I think Paul is talking about a different demo, one where we're just
able to boot all four qemu architectures alongside each other.

This should be possible with our release images, we just need someone to
own it and to bring a machine with it working on it (and have a backup
of the setup in case of filesystem corruption etc.).

Any volunteers?

Cheers,

Got it. At a top level the requirement is showing stuff running on real
hardware (all archs) as well as within QEMU (all archs). As far as what
is shown on what, that's another matter.
