As the curtains rose on opening day of Embedded Linux Conference Europe & Open Source Summit Europe in Edinburgh, the latest release of the Linux Kernel, 4.19, was made available by Greg Kroah-Hartman. Collaborans were once again very active, so here's a look at their contributions. Head to LWN.net if you would like to read more about the first half and second half of the merge window for 4.19.

In this release, Collabora contributions were made by 9 different developers, authoring a total of 87 patches, 125 Signed-off-by tags, 14 Reviewed-by tags and 8 Tested-by tags.

Media

• Ezequiel Gracia fixed the previously broken Rockchip 2D Raster Graphic Acceleration unit (RGA) driver.
• Ezequiel also fixed several race condition issues and did several cleanups in the Media framework.
• Nicolas Dufresne improved validation of the buffers from the USB video device class driver to avoid application crash or run-time failure.
• Nicolas also fixed the stream time in the Virtual Video Driver (vivid) on interlacing mode to ensure proper frame render.

Graphics

• Now that the DRM framework supports storing GEM objects directly in drm_framebuffer, Daniel Stone converted several drm drivers to use this structure and several important cleanups in the DRM framework.
• Gustavo Padovan worked as a maintainer on DRM subsystem reviewing and merging branches.

Here, there and everywhere:

• Ezequiel Garcia added support for the 96boards RK3399 Ficus board (ROCK960 Enterprise Edition).
• Enric Balletbò continued to improve support for Chromebook devices with cleanups on the ChromeOS Embedded Controller and PWM-powered blacklight devices.
• Enric also worked on improving the support for Lightwriter Toby-Churchill SL50 board, Rockchip rk3399 SoC and the Ficus board.
• Sebastian Reichel worked on GE Healthcare PPD biometric monitor, he added 3v3 regulator information in its device tree and also enabled PMU and hardware counters so that they can be properly used with the 'perf' tool.
• For the TI SoC with LCDC display, Sjoerd Simons fixed the case when panels probing was being delayed.
• Lubosz Sarnecki updated EDID information for the HTC Vive Vive Pro VR Headsets.
• Nick Milner improved the Rockchip rk3399 DMC (Dynamic Memory Controller) device documentation.
