Health monitors, Embedded devices, Computers,
Intelligent cables, Thermostats, Routers, Switches,
Smart lights, Storage, Set Top Boxes, Cars, TVs,
Digital Cameras, Camcorders, Smart Meters,
Microservers, Hyperscale servers .....
• ARM is everywhere

13. Industry Disruption
• Today – the entire industry is being disrupted
• Mobile - Smartphones, Tablets
• Embedded markets - TV, Cameras, Consumer electronics, Cars
• Networking - Routers, Switches, Cloud
• Servers - Micro, Hyperscale, HPC
• IOT - Huge future impact on cloud, data, analysis
• One size no longer fits all
• One vendor alone cannot compete
• ARM’s business model and partners are key

14. Meeting the Challenge
• Two key agents of change:
SoCs Open Source Software

15. ARM SoCs
• Building Blocks
• R/M Microcontrollers
• Cortex-A Series
• 32 bit ARMv7 A5 to A15, including big.LITTLE
• 64 bit ARMv8 A53, A57
• Mali GPU – Graphics or GPGPU
• Trustzone security
• All cores implement the ARM architecture
• ARM vendors then focus on value add
• Low cost multicore devices
– e.g. 4 core A7 and baseband for low cost smartphones/tablets
• High end 32 and 64 bit functionality
– e.g. server focused SoCs with accelerators,
interconnect I/O and fabrics

16. Example - Networking & Servers

17. Open Source
• One company alone cannot develop and support
software for this rate of innovation
• Open source software is the only viable solution
• Linux is evolving rapidly as change accelerates
• Depends on an increasing number of contributors
• 2,829 developers from 407 companies contributed to Linux 3.4-3.8*
• Working upstream - forking and maintaining is very expensive
• Working inside the open source community saves time & money
• Open source is a huge shared-cost ecosystem
*Source: Greg Kroah-Hartman, Linux Foundation

18. Example - Android
• Open source platform for mobile devices based
on Linux
• Current version is Android 4.2 Jelly Bean

19. Android in Linaro
Android is important for Linaro
• Engineering activities
• Power Management – multicore,
• Tools optimizations – gcc, cortex-strings
• New ARM technology test & validation – big.LITTLE, ARMv8
• Upstreaming Android functionality to mainline
• Gives us a platform for testing
• Stresses the components that we’re engineering
• Gives us a platform for benchmarking
• Looking for areas to improve performance of the overall system
• Google leverages Linaro’s kernel work

20. Industry Collaboration
• Linaro
• Competitors collaborating on engineering of core software
• Sharing the cost of common software foundations
• The industry is changing from single proprietary
suppliers for core technologies, to open source driven
partnerships built on collaboration

21. Innovation
• Working together from requirements to solutions
• Sharing and lowering costs
• Building standard platforms that enable value-add
• Examples: kernel optimization, SoC hardware acceleration, fabrics

22. Beyond arm-soc
• ARM dominates mobile
• Intel dominates server chips
• Each is moving into the other’s market
• Mobile Linux kernel technology is being used in the server
space and vice-versa, especially in power management
• We can no longer work in just the ARM community
• Greg Kroah-Hartman – Linaro Connect, Hong Kong February 2013
• ARM/PMWG maintains CPUFreq with Intel, and Linaro has contributed
over 40% of the kernel patches in this subsystem since Linux 3.7
• LKML discussions on the scheduler changes for GTS*
• Linaro is adding Intel into LAVA for CI loop test and validation
• Industry collaboration is becoming critical for success,
and Linaro has a key part to play
*Global Task Scheduling a.k.a. big.LITTLE MP

23. Linaro – Making the Difference
• Our core work
• Linux kernel, Power Management, Graphics & Multimedia,
Tools, Engineering Builds & Validation (LAVA)
• Key glue between SoC vendor innovation and Linux
• Not just the kernel
• Tools, Virtualization, Languages, Stacks, Middleware
• Open Source Security is an area of increasing interest to members
• Groups
• LEG (Servers), LNG (Networking Equipment)
• Working in specific areas where a group of companies wants to share
software development costs e.g. STB/TV, Embedded, Automotive
• Our focus is on optimizing and building the core platform and
tools to support innovation and differentiation

24. Summary
• SoC innovation, power efficiency and choice of silicon
suppliers will drive further ARM growth across the industry
• Innovation and differentiation drives the need for common
platform software to prevent costly fragmentation
• Open Source is evolving rapidly to enable disruptive
solutions to the explosion in user data and analysis
• Users, Frameworks, Distributions, OEMs, Silicon vendors
are collaborating more closely than ever before, enabled by
Open Source
• Linaro is a key enabler in the ARM ecosystem
