Linux Kernel 4.9 was released this week and once more Collabora developers took part on the kernel development cycle. This time we contributed 36 patches by 11 different developers, our highest number of single contributors in a kernel release ever. Remember that in the previous release we had our highest number total contributions. The numbers shows how Collabora have been increasing its commitment in contributing to the upstream kernel community.

For those who want to see an overall report of what was happened in the 4.9 kernel take a look  on the always good LWN articles: part 1, 2 and 3.

As for Collabora contributions most of our work was in the DRM and DMABUF subsystems. Andrew Shadura and Daniel Stone added to fixes to the AMD and i915 drivers respectively. Emilio López added the missing install of sync_file.h uapi.

Gustavo Padovan advanced a few more steps on the goal to add explicit fencing to the DRM subsystem, besides a few improvements to Sync File and the virtio_gpu driver he also de-staged the SW_SYNC validation framework that helps with Sync File testing.

Peter Senna added drm_bridge support to imx-ldb device while Tomeu Vizoso improved drm_bridge support on RockChip's analogic-dp and added documentation about validation of the DRM subsystem.

Outside of the Graphics world we had Enric Balletbo i Serra adding support to upload firmware on the ziirave watchdog device. Fabien Lahoudere and Martyn Welch enabled and improved DMA support for i.MX53 UARTs, allowing the device tree to decide whether DMA is used or not. Martyn also added a fake VMEbus (Versa Module Europa bus) to help with VME driver development.

On the Bluetooth subsystem, Frédéric Dalleau fixed an error code for SCO connections, that was causing big timeout and failures on SCO connection requests. Finally Robert Foss worked to clear the pipeline on errors for cdc-wdm USB devices.
