+# Ross Burton, Userspace Architect for Yocto
+# Open Source Technology Centre at Intel
+# This session is a high level introduction to the Yocto Project
+

+What is the Yocto Project?
+# Appears to be confusion in the automotive community about the Yocto Project.
+# What is is, what it can offer and so on.
+# We were invited by the LF to come here and clarify what Yocto is.
+# So, the Yocto Project is...
+
+-- [umbrella.jpg] [duration=13.583521]
+Umbrella project
+# An umbrella project.
+# You don't download or install the Yocto Project itself
+# Just like you don't install the Apache Foundation
+
+-- [tools.jpg] [duration=27.991919]
+Build environment
+and development tools
+# An embedded build environment and development tools
+# Specifically, a build system (bitbake), package metadata (oe-core),
+# Eclipse plugin, Application Development Toolkit (deployable toolchain)
+
+-- [cpus.jpg] [text-align=center] [center] [duration=49.765675]
+x86 • ARM
+MIPS • PowerPC
+# We support all of the big architectures.
+# oe-core builds for qemu machines for all of these architectures
+# Ensures that the core builds for everything
+# Optional BSPs for specific platform support
+# Everything is cross compiled, so no "but it worked for x86" problems
+
+-- [people.jpg] [duration=22.377592]
+Collaboration space
+# Finally YP is a collaboration space, providing a forum
+# for users to share their problems and solutions
+# Public mailing lists and weekly phone conference
+# PAUSE
+
+-- [minifigs.jpg] [center] [duration=18.553514]
+So many choices…
+# When picking a platform what's the difference between yocto and
+# android, linaro, tizen, buildroot, baserock, or hacking your
+# favourite desktop distribution...
+
+-- [engineer.jpg] [duration=56.184429]
+…why pick the Yocto Project?
+# YP is Linux for embedded, from a small ARM board to mission critical
+#  xeon clusters
+# Builds a custom distro suited to your needs
+# Easy to add, remove, or change components
+# Open development process, no code drops or license complications
+
+-- [cables.jpg] [duration=40.872715]
+Some are easy to hack on,
+but you’ll regret it later
+# Especially if your target is x86, it's easy to start with a
+# desktop distribution and chop pieces out
+# Building new pieces and rebuilding the pieces that need changes
+# But when you need to change hardware, or rebuild with different compiler flags
+# It's not that easy any more
+
+-- [road.jpg] [top] [duration=47.108444]
+Designed for the long term
+# Yocto is designed for long term use
+# Six monthly release cycle but maintained release branches
+# Commercial support from OSVs
+# Tools to help do the mundane distribution building
+# - Generate package repos and disk images
+# - Static release archives for license compliance
+
+-- [tumble.jpg] [top] [duration=45.338825]
+Won’t fall apart in time
+# Yocto won't surprise you late in product development
+# Reproducable builds for the entire system
+# Clear process for updates - easy to make the changes
+# and publish a new image or repo
+# GPL compliant - trivial to public source *and* build instructions
+

+Advisory Board
+# finally should mention the advisory board.
+# Yocto is a project at the Linux Foundation, not owned by any
+# particular company
+# The advisory board is comprised of reps from member companies
+# working on Yocto
+# The boards first action was to name itself "advisory board" rather
+# than "steering group" to reflect that it offers advice and input and
+# doesn't control the project technical direction entirely in the
+# hands of the architects and maintainers
+

+How does it work?

+# How does it work?
+

+It’s all about the layers
+# A YP distribution is assembled from a number of layers

+# The build output is configurable per build and per machine. This

+# typically bootable on those.  Build for a say beagleboard and you'll
+# get kernel, bootloader and rootfs tarballs to write a SD card.
+# alongside the images directory there is the package repository that
+# was used to construct the root fs. This can be shared on the network
+# and used as a normal repository, ie install some development or

+Virtualisation
+# I expect virtualisation to be common in next-generation automotive
+# systems as individual processors become more powerful and logically
+# separate systems are ran in virtual machines on fewer physical
+# processors.
+# Because systems built by Yocto can be trivially tuned to be exactly
+# what is required and nothing else they are a good match for
+# virtualised systems, both as a minimal host that does simply manages
+# the virtual machines, or as a specialized virtual machine itself.

+Specialised subsystem
+# Cars are complicated beasts these days with many processors performing specialised roles
+# Dashboard, engine management, and so on.
