Linux Kernel 4.4 was released this week and Collabora engineers helped in the development of the new kernel in a few different areas. A total of 38 patches from 8 Collabora engineers were added, making it the kernel release with the most Collabora developers ever! Only 7 of the 8 engineers are still part Collabora however, as unfortunately Javier left a few months ago, after completing his patches.
On that note, Collabora is hiring experienced kernel hackers to further increase our participation in the Linux Kernel. If you are interested, please drop a line!
In this release Daniel Stone fixed a potential circular deadlock when loading the i915 GuC firmware and incorrect pipe paramenter on drm_crtc_send_vblank_event() that was leading to WARN_ON. Danilo Cesar Lemes de Paula improved the kernel-doc script to fix an issue with struct drm_modeset_lock not showing at the final kernel Doc and fixes a fault in the highlight processing by using arrays instead of hashes.
Emilio López enabled EC verified boot context on Peach Boards and driver to read/write nvram’s verified boot context to/from userspace for Chromebook devices and Enric Balletbo i Serra added support for TI’s tps65217 charger driver while Gustavo Padovan added cursor support on exynos DRM driver. Javier did some improvements to the Chromebook EC driver.
Sjoerd Simons added rockchip support by default on ARM multi_v7_defconfig and a driver for the SPDIF audio transceiver on rockchip boards. Tomeu Vizoso removed the regulator_list as it was redundant because the regulators devices can be found through the regulator_class, fixed an clk reparenting issue on exynos5250 that was preventing the screen to work after the second suspend.
