The kernelci.org project aims to improve the quality of the mainline Linux kernel by improving testing and validation across the wide variety of diverse hardware platforms that run Linux.
There are so many different devices and platforms that run Linux, and Linux kernel development is moving so quickly that it is difficult to ensure that any given platform will remain working and stable with each Linux version. As an example, the chart here shows the growth in the number of 32-bit ARM based devices supported by Linux, with the total number of unique devices as of v4.11 just shy of 1400! That doesn’t even count the growing number of 64-bit ARM devices or any of the other architectures like x86 or MIPS.
With such an incredible range of supported hardware, how can the Linux kernel community continue to ensure that all of this hardware remains well supported and evolves with the rest of the Linux kernel?
The kernelci.org project set out to help solve that problem.
During the development cycle of the Linux kernel, whenever there are changes to the source-code repository, the kernel is built in a wide variety of configurations for several different architectures. Today, there are over 270 different build configurations across 4 architectures (x86, MIPS, ARM and ARM64.)
After a successful build, the kernel images are made available to the several distributed labs for testing. Due to the diversity of hardware that runs linux, no one lab is going to have all the hardware, so kernelci.org was designed for distributed testing. When builds are completed, each lab can download the images for the hardware available, and perform the testing. Currently there are 8 active labs contributing a total of more than 250 unique hardware platforms across 4 unique architectures.
BayLibre’s Kevin Hilman is a founding developer of the kernelci.org project, and today, BayLibre has the largest lab contributing results from over 80 unique boards across 25 unique SoC families and performing thousands of tests each day.
If you have hardware you’d like to see tested with the latest Linux kernel in the kernelci.org project, feel free to contact us. We can help guide you through setting up your own lab, or you could just send us your hardware and we can add it to our lab.

An excellent summary of this release can be found at KernelNewbies, and below is a summary of our contributions, organized by SoC family and a summary graph of contributions by developer. A special shout-out this development cycle goes to Neil Armstrong for the significant contributions of new DRM/KMS support for Amlogic SoCs.
The v4.9 release of the Linux Kernel has just been announced, and BayLibre has made the top 20 list of companies contributing to the Linux Kernel this release.
As described in the LWN coverage, this is largely due to the inclusion of Greybus in the staging tree, but BayLibre has also been active in several other areas:
Amlogic SoC family
added SPI support for flash controller (spifc)
added USB host support
added PWM support
added secure monitor support and NVMEM
added watchdog support
added AO clocks and reset
added IR/remote support
added I2C support
added MHU/mailbox support
network: added new DWMAC glue supporting GXBB
TI DaVinci SoC family
added LCDK board support
Audio support
NAND support
Ethernet
MMC/SD supported
ARM OxNAS SoC family:
clocksource driver updates
Fixes, cleanups for BayLibre ACME hardware:
gpio: pca953x: code refactoring
gpio: fix an incorrect lockdep warning
