5 Training Embedded Linux development Linux kernel and driver development Android system development Yocto Project and Open Embedded development Training materials freely available (CC-BY-SA) On-site sessions (worldwide) Public sessions (France) Known-worldwide Customer evaluations transparently available

6 Training customers System makers Silicon vendors

7 Services Linux Board Support Package Port a bootloader and the Linux kernel to custom HW platforms Write Linux device drivers Integrate a Linux system with Yocto Project or Buildroot Linux kernel mainlining Help to include and maintain code in the official Linux kernel for a particular architecture, processor, board or device. System optimization Consulting and technical support Embedded Linux and Android: optimize the boot time, the system size, the memory consumption, power consumption or real-time latencies. Bring our expertise to choose hardware properly supported and the right software stack for a Linux or Android project and support engineering teams.

8 Kernel upstreaming Contract with several semiconductor vendors Upstream in the official Linux kernel the support for the vendors ARM processors: Marvell EBU Marvell Berlin Atmel AT91 and SAMA5 Writing new kernel code, or bringing existing code to mainline quality. Pushing the code to the community, taking into account comments and reworking the code accordingly. Hundreds of man days effort, thousands of patches merged in the Linux kernel

9 Board Support Package Multiple complete Linux BSP for custom hardware platforms Freescale I.MX28 and I.MX6, TI AM335x, Atmel SAMA5D3 and AT91, Marvell Armada Bootloader and Linux kernel porting, device driver development, Buildroot or Yocto Project build system Patches sent to the upstream projects when applicable Example: hardware from Crystalfontz A base board with the Freescale I.MX28 ARM processor, RAM, USB gadget, OLED screen, usd card Six expansion boards with various peripherals All supported in mainline Barebox and Linux!

10 Boot time optimization Multiple boot time optimization projects Air Liquide (France), on ARM AT91 platform Glintt (Portugal), on a MIPS platform Maxim Integrated (France), on a ARM based SoC platform Globalcom Engineering (Italy), on a MIPS platform Maker of home automation systems (Spain), on a x86 platform For each project, an audit of 7 days reached the optimizations goals, provided details on the implemented optimizations, made numerous suggestions on how to further optimize the system Transferring the knowledge at the end of the projects is a key value of Free Electrons engineers.

11 Open-source community Free Electrons engineers are members of the open-source community Contributions to open-source projects like the Linux kernel, Buildroot, Yocto Project, Barebox, U- Boot, etc. Engineers attending the most important Embedded Linux conferences, learning about the latest technologies, and meeting key open-source developers from various projects. Incitement in our customer projects to contribute back the improvements. Training materials freely available. Provide the best of the community

12 Mainline Linux kernel Contributions to various platforms, mostly on ARM Latest commits: see Several Linux kernel maintainers Maxime Ripard for Allwinner ARM SoC support. Gregory Clement co-maintainer for ARM Marvell EBU SoCs Alexandre Belloni RTC subsystem maintainer and comaintainer for Atmel ARM SoC support In the top 30 contributing companies since 2013, most of the time between number 10 and 20. Total number of commits, as of Linux 4.3-rc7: 688 Maxime Ripard 670 Thomas Petazzoni 385 Alexandre Belloni 335 Ezequiel Garcia 239 Boris BREZILLON 223 Gregory CLEMENT 155 Michael Opdenacker 104 Antoine Ténart (from git shortlog sn author="free electrons")
