  • www.linaro.orgSlide 4 EUROPE 2012 (LCE12) ARM Linux Influence  from: “Gaah. Guys, this whole ARM thing is a f*cking pain in the ass.” Linus Torvalds, March 11th, 2011  to: “Over the last year, ARM has gone from a constant headache every merge window to an outstanding citizen in the Linux community” Linus Torvalds, August 29th, 2012
  • www.linaro.orgSlide 5 EUROPE 2012 (LCE12) What’s Next  THIS WEEK A very full agenda – more than 150 sessions and meetings  Mobile, Server, Networking, Power Management, ARMv8, landing teams, Android, LAVA, big.LITTLE, gcc, KVM & more  Watch out for a further Linaro-related announcement on Thursday – here on Thursday at 5.45pm

  • EUROPE 2012 (LCE12) David A Rusling, Linaro CTO The Future
  • www.linaro.orgSlide 10 EUROPE 2012 (LCE12) William Gibson “The future is already here — it's just not very evenly distributed” August, 1993 http://www.williamgibsonbooks.com/
  • www.linaro.orgSlide 11 EUROPE 2012 (LCE12) Clues?
  • www.linaro.orgSlide 12 EUROPE 2012 (LCE12) Think Holistically  Need to turn our attention to the whole system  Look for efficiency of the system as a whole  How do we balance computation across all computing elements for the best battery life / performance?  Engineer to support the diversity of ARM  Let's not slavishly follow Intel's example  Need to consider all application spaces, not just mobile
  • www.linaro.orgSlide 13 EUROPE 2012 (LCE12) Linux Kernel  Ideally the kernel would  Support a wide diversity of hardware implementation (from smart 'internet of things' devices to mobile, HPC and 'smart planet')  Be dynamically tunable for performance versus energy usage  Instrumentation, measurement, feedback  Interactions with user space methods / mechanisms  Key sub-systems need re-engineering  Power management  Scheduling  Networking
  • www.linaro.orgSlide 14 EUROPE 2012 (LCE12) Heterogeneous Systems  Systems are a mixture of CPU, GPU, DSP etc  Highly complex interactions (especially if you add security and virtualization)  Programming across these devices is generally fixed at design time  How can we distribute work across these compute engines efficiently?  OpenCL (CPU / GPU)  HSA Foundation (http://hsafoundation.com/)
  • www.linaro.orgSlide 15 EUROPE 2012 (LCE12) Linaro Needs Re-engineering Too  Organisational change is inevitable  New members, new groups, wider focus  Linaro could more or less double in size in the next 12 months  Need to reaffirm our key values (upon which our reputation is dependent):  Openness  Upstream working  Collaboration  Above all we're an engineering organisation  With a reputation for integrity and excellence
