9. CELF Test Lab Located in San Jose Run regression tests on Linux kernel
Support for automated and remote operation
Power control, serial console, etc
Test scheduling via a web interface
Run regression tests on Linux kernel
Results published at testlab.celinuxforum.org
One example: Bloatwatch

10. Hardware Donations
Architecture Group has small amount of money to use to donate hardware to community developers

11. DLNA Relationship CELF is a member of DLNA's liaison program
This gives us early access to specs under NDA
We also get 3 free specifications, as they are made available to the public

12. Ideas to support DLNA effort
Specifications
Hardware
Plugfests
DLNA Certification
DLNA Test Suites
Sponsoring DLNA membership
Code donation
Work Donation
Summits
Funded Project work

13. Specifications
CELF can donate DLNA specifications to open source projects.
We get 3 copies for free
We could purchase more if necessary
2 copies of the spec have already been delivered
I have one sitting on my desk in San Jose
I also have 3 stacks of update documents sitting on my desk
Who would like these?

14. Hardware
It might be nice to provide hardware for DLNA compatibility testing
How to get hardware:
CELF has a small budget for hardware for developers
CELF could allocate additional funds for this specific purpose
CELF could ask members to donate requested products
What hardware is desireable?

15. Plugfests DLNA hosts plugfests
These are events where companies bring their products to test interoperability.
They are covered by NDA
I don't think it’s a good fit for open source
How about hosting our own plugfest - either standalone or at a CELF conference
CELF could provide hardware (see previous slide), venue or logistical support for an event

16. DLNA Certification
DLNA certification can be obtained through a DLNA- certified lab
You must be a DLNA member to certify (I think)
Maybe a lab can test interoperability, without granting an official certification
I believe certification is granted to a software/hardware combination
It might not make sense to try to certify software by itself
Maybe the certification should be the responsibility of the hardware maker who uses an OSS DLNA stack

17. DLNA Test Suites
Test suites from the DLNA organization are available to DLNA members
CELF members may have DLNA test suites they would be willing to loan, or make open source, for use by OSS DLNA projects

18. Sponsoring DLNA Membership
CELF could pay for DLNA membership for an organization that was leading an open source DLNA project
CELF could convince DLNA to create a special class of member for open source projects
Given the IP rules for DLNA membership, this seems unlikely to work

19. Code donation
One or more CELF members could donate code to seed or assist and open source effort

20. Work donation
CELF members could apply engineering resources to OSS DLNA project work
Work could be development, testing, documenting, etc.

21. Summits
CELF and/or DLNA could support future summits, if this one is helpful

22. Funded Project work
CELF could fund DLNA development and maintenance work

23. Notes on working with DLNA
DLNA chair and board
DLNA contact information
How to influence DLNA

24. DLNA Chair and Board Scott Smyers (Sony) is the Chair of DLNA
Interesting Trivia: Scott Smyers founded CELF and DLNA the same day - June 23, (one in Tokyo and one in San Francisco)
DLNA Board of Directors is:
Sony, Panasonic, Philips, Samsung, Intel, Microsoft, HP, Nokia
7 out of 8 are CELF companies, friendly to open source

25. DLNA Contact information
CELF's DLNA liaison is Manjunath Ramachandra
DLNA's Industry Liaison Subcommittee Chairman is Michael Stelts
DLNA's executive director is Donna Moore
DLNA's Ecosystem Committee chairs are Scott Loffgren of Intel and Jim Battaglia of Pioneer.
This group might have an interest in supporting open source projects around DLNA.

26. Influencing DLNA
Scott believes the board would consider adopting an open source DLNA stack as a reference stack
Scott recommends pushing things through the liaison or ecosystem groups, but also by having a board member bring up a topic directly to the board (for funding, requests, etc.)
Scott believes the DLNA would be responsive to funding requests for certain activities
Should consider DLNA assistance in all activity ideas for CELF sponsorship

27. Discussion and brainstorming
