CE Linux Forum
The CE Linux Forum (CELF) is focused on the
advancement of Linux as an open source
platform for consumer electronics devices.

CELF Test Lab

• Located in San Jose
• 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 its 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, 2003. (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
