Linux Kernel 4.8 is out and once more Collabora engineers did a significant contribution to the Kernel. For this latest release, Collabora provided 101 patches from 8 engineers, our biggest contribution to date for a single kernel release! We’ve also seen the first contribution from Frederic Dalleau since he joined Collabora. LWN.net covered the new features of the new kernel in three different posts, here, here and here.
On the Collabora side of the contributions we touched a few different areas in the kernel. Bob Ham, who recently left Collabora, added support for the Alea I Random Number Generator, while Enric Balletbo improved the audio support on the Rockchip rk3288 SoC. Frederic Dalleau fixed an important memory leak on the Bluetooth stack.
Gustavo Padovan continued his work add Explicit Synchronization for Buffer Sharing on the kernel. In this release he added fence_array support and prepared the SW_SYNC interfaces for de-staging, SW_SYNC meant to be used for Explict Syncronization testing. He also worked in removing some of the legacy functions from drm_irq.c from the kernel.
Helen Koike added some improvements and clean ups to the ASoC subsystem mainly on the max9877 and tpa6130a2 drivers. Nicolas Dufresne fixed the bytes per line calculation on YUV planes on the uvcvideo driver.
Thierry Escande added many improvements the NFC digital layer and Tomeu Vizoso added a new helper for the ChromeOS Embedded Controller and improved usage of DRM Core APIs on the Rockchip driver. He also fixed an issue with the Analogix DP on Rockchip that was not enabling clocks in the correct order.
