Business Models

3.
Linaro Overview
• Linaro is a not for profit software engineering company
• Members are ARM SoC vendors and other companies interested in the
ARM ecosystem
• Rather than each company duplicating open source effort for common
software, the cost is shared, and the software is built once
• The work is carried out in the open, and the results are extensively
tested and then upstreamed into the relevant open source projects –
e.g. kernel.org
• Today Linaro has over 200 engineers, about half are employees, half
assignees

Industry Disruption
• Today – our entire industry is being disrupted
• Mobile - Smartphones, Tablets, Wearables
• 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

8.
Meeting the Challenge
• Key agents of change:
SoCs Open Source Software

9.
A Tour of the Market for ARM SoCs
• Servers
• Networking Equipment
• Automotive
• Digital Home
• Mobile
• Embedded/IoT

10.
Servers

11.
Why Consider ARM Servers?
Predictions
• ARM servers will be lower cost
• Throughput/$ and TCO
• ARM servers will be more compact
• Throughput/space
• ARM servers will use less power
• Throughput/Watt
• Not just CPU cores – due to innovation in SoC integration
• There will be more choice in the ARM server space,
and software platforms will ensure compatibility

12.
How long will it take?
• 2013
• Applications: Storage/Streaming servers, Web server cluster
• ARMv7 Cortex-A15, 1.5+GHz, LPAE, higher performance
• Applications: memcached, Web server cluster, storage, some database apps
• 2014
• ARMv8 64 bit Cortex-A57 cores delivered in SoCs
• First 64 bit servers will appear
• Software ecosystem will rapidly develop
• Applications: Data Center Enterprise Servers,
Virtualized platforms
• 2015 onwards
• ARM servers will be mainstream

13.
Server Software
• Linaro is building, validating and optimizing key
software enablers for ARMv8
• Work started in 2012 on ARM models
• Now running on first hardware
• Goal is enabling open source and
commercial ISVs to rapidly deploy
applications when multinode servers
are available from 2014 onwards

14.
Current LEG Members
• Group Director: Andrea Gallo

15.
Networking Equipment

16.
Linaro Networking Group
• There is an accelerating need for engineering effort for ARM-based
networking equipment. Fragmentation and duplication will result unless
this effort is coordinated.
• Standards for ARM-based network equipment need to be agreed
• A scalable model is needed to enable ARM vendors to supply
cross-SoC software stacks and tested SDN/NFV platforms

17.
Networking Equipment
• Key technical areas
• RT Patch set
• Virtualization
• LTS kernel version for LNG
• Big-endian support for legacy code
• Data Plane APIs/frameworks

18.
Current LNG Members
• Group Director: Raj Murali

19.
Automotive

20.
Automotive
• Fragmented marketplace
• Multiple Platforms
• Sync (Ford/Microsoft)
• Genivi (Linux)
• Automotive Grade Linux (Tizen/Linux Foundation)
• iOS (Apple)
• Android
• Long design-in/decision cycles

21.
Automotive
• Linaro delivers ROI to members when there is an opportunity to
colloborate and share software development costs for mutual
benefit
• The automotive IVI market remains fragmented and SoC
vendors tend to “lock-in” to long term design wins with specific
car manufacturers
• Linaro could form an automotive group if there was demand
from the manufacturers and SoC vendors for engineering
common open source software implementations

22.
