Linux Kernel 4.6 was released this week, with a total of 9 Collabora engineers taking part in its development, Collabora’s highest number of engineers contributing to a single Linux Kernel release yet! In total Collabora contributed 42 patches.

As part of Collabora’s continued commitment to further increase its participation to the Linux Kernel, Collabora is actively looking to expand its team of core software engineers. If you’d like to learn more, follow this link.

Here are some highlights of Collabora’s participation in Kernel 4.6:

Andrew Shadura fixed the number of buttons reported on the Pemount 6000 USB touchscreen controller, while Daniel Stone enabled BCM283x familiy devices in the ARM multi_v7_defconfig and Emilio López added module autoloading for a few sunxi devices.

Enric Balletbo i Serra added boot console output to AM335X(Sitara) and OMAP3-IGEP and fixed audio codec setup on AM335X using the right external clock. Martyn Welch added the USB device ID for the GE Healthcare cp210x serial device and renamed the reset reason of the Zodiac Watchdog.

Gustavo Padovan cleaned up the Android Sync Framework on the staging tree for further de-staging of the Sync File infrastructure, which will land in 4.7. Most of the work was removing interfaces that won’t be used in mainline. He also added vblank event support for atomic commits in the virtio DRM driver.

Peter Senna improved an error path and added some style fixes to the sisusbvga driver. While Sjoerd Simons enabled wireless on radxa Rock2 boards, fixed an issue withthe brcmfmac sdio driver sometimes timing out with a false positive and fixed some issues with Serial output on Renesas R-Car porter board.

Tomeu Vizoso changed driver_match_device() to return errors and in case of -EPROBE_DEFER queue the device for deferred probing, he also provided two fixes to Rockchip DRM driver as part of his work on making intel-gpu-tools work on other platforms.
