Linux 4.1 was released last week and like previous kernel releases, this version again contains contributions made by Collabora engineers as a part of our current projects.

On this release, not only Collabora contributed several patches for different subsystems but also for the first time made it to LWN list of most active employers for a Linux kernel release and Tomeu Vizoso was listed as one of the most active developers by changed lines.

In total 68 patches were contributed to the 4.1 release. These were for:

  • Fixes and improvements to the DRM core atomic support.
  • Fix for Exynos DRM FIMD buffer size calculation.
  • More cleanup and fixes for Exynos DRM in preparation to finish porting the driver to support Atomic Mode Settings for v4.2
  • Add MMC/SDIO power sequencing to make the WiFi chip work on Snow and Peach Pit/Pi Chromebooks.
  • Various fixes and improvement for the ChromeOS Embeded Controller drivers.
  • Add default console serial port configuration for Exynos Chromebooks to avoid having to define a tty in the kernel command line.
  • Enable needed drivers in the Exynos default configuration file.
  • Fix error code propagation in the MMC power sequencing core.
  • Restore clocks needed during suspend for Exynos5 machines to prevent failing to resume.
  • Make the Mwifiex chip on Exynos Chromebooks to keep power during suspend to prevent the driver not allow the system to enter into a suspend state.
  • Fix output disable race on the Samsung PWM driver.
  • Split out touchpad initialisation logic on the Atmel MaxTouch driver.
  • Various enhancements for the Tegra ASoC driver.
  • Add a Device Tree to support the Nyan Blaze Chromebook and factor out common snippets with the Nyan Big Chromebook Device Tree.
  • Add trackpad, WiFi and GPIO restart support for the Nyan Chromebooks.
  • Add support for the Tegra124 Activity Monitor (ACTMON).
  • Fill EMC timings for Tegra Nyan Chromebooks.
  • Many fixes and improvements for the Tegra device frequency scaling driver.
  • Fix the Tegra DRM driver by resetting the SOR to a known state.
  • Enable many drivers in multi_v7 default configuration, that are needed by Tegra Chromebooks.
  • Fix the cros_ec keyboard driver to avoid loosing the key pressed during suspend to resume the system.
  • Fix USB not working on Tegra124 based boards.

Following is the complete list of patches merged in this kernel release:
