Linux kernel 3.8 released, Free Electrons top #17 contributor

Thomas Petazzoni and Grégory Clement, Free Electrons kernel engineers

Thomas Petazzoni (front) and Grégory Clement (back) at the Embedded Linux Conference 2013 in San Francisco, discussing ARM Linux kernel issues.

Early last week, version 3.8 of the Linux kernel has been released by Linus Torvalds. The KernelNewbies web site, has, as usual, a great summary of what’s new in this release, together with lots of links to the relevant LWN articles. With 12394 commits, 3.8 has been the busiest ever kernel release cycle, the previous record being held by 2.6.25 with 12243 commits.

Despite this huge activity, Free Electrons has been the 17th most active employer during the 3.8 cycle, with 128 commits merged into the mainline Linux kernel, representing a bit more than 1% of the total number of commits. See the statistics by employer at http://www.remword.com/kps_result/3.8_whole.html and in the traditional LWN article. This puts Free Electrons before Nvidia, Qualcomm, ARM or Oracle in number of commits, and just a few commits behind Freescale. See the Git repository for the list of our contributions.

In detail, Free Electrons contributions for 3.8 have been:

  • A large number of contributions related to the support of the Marvell Armada 370 and Armada XP SoCs, done by Grégory Clement and Thomas Petazzoni. Contributions included: a new network driver for the Armada 370 and Armada XP, support for the Armada XP-based OpenBlocks AX3 platform, support for the Armada 370-based Globalscale Mirabox platform, a big number of improvements and Device Tree support for the Marvell XOR engine driver, beginning of Device Tree support for the older Marvell Orion5x SoC family, support for the L2 cache found in Armada 370/XP, clock drivers for Armada 370/XP, SMP support for Armada XP, enabling of SATA on Armada 370/XP platforms.
  • The contribution of the initial support for a new SoC family in the mainline Linux kernel: the Allwinner A10 and Allwinner A13 ARM SoCs. This support has been contributed by Maxime Ripard, who has become the maintainer for this new ARM sub-architecture.
  • A driver for the I2C-based SSD1304 OLED display, a nice 128×32 pixels monochrome OLED display, contributed by Maxime Ripard.
  • A number of improvements in the support for the Crystalfontz i.MX28-based platforms, the CFA10036 and its expansion board the CFA10049. These contributions have also been made by Maxime Ripard.

Through these contributions, Free Electrons have gained a good expertise in support for ARM SoCs and boards inside the Linux kernel. If you are interested in having us help you bring the support of your ARM board or ARM SoC into the mainline Linux kernel, do not hesitate to contact us, you will be directly answered by our engineers doing Linux kernel development!

    You did a really great job guys, thanks to your work, I can already play with my mirabox. Keep up the good work !

  2. Tim says:

    Am I the only one who is noticing that support for the Atheros AR9485 wifi chip isn’t included in this release, as well as the presious one? Do you guys know what the deal is? What’s Torvalds up to? If this persists I’ll be stopped dead in my tracks as far as upgrading kernel vers.

  3. Update: Free Electrons is the 30th biggest contributor to Linux 3.9. See http://www.remword.com/kps_result/3.9_whole.html
