Linux Kernel 4.15 was released yesterday, and it once again contained patches contributed by Collabora! While the total number of contributions was lower than previous releases (19 patches by 6 different engineers), Collaborans worked on some bigger patchsets that took a longer time to merge, like V4L2 Explicit Synchronization and UTF-8 case insensitive lookups for EXT4

Collabora has also put a lot of work on implementing bisection support for kernelci.org. We've also seen Gustavo Padovan take on the role of drm-misc co-maintainer — the tree for DRM core and small DRM/KMS drivers. We left our Reviewed-by on 54 patches this release. There was also 28 Signed-off-by tags and for patches that were tested by Collabora engineers.

This release was very atypical with the merge of KPTI, a giant memory management patchset, late in the release candidates series to secure the kernel against the Meltdown attack. More information about general features of 4.15 release can be found at LWN.net, see part 1 and part 2 articles.

For the Collabora contributions Martyn Welch contributed some fixes to the i.MX serial driver, Gabriel Krisman Bertazi fixed a DRM buffer modifier for the Gemini Lake core from Intel. Gustavo Padovan added DRM asynchounous cursor update through atomic API to freedreno.

Fabien Lahoudere added device tree information for a GE Healthcare device. Thierry Escande fixed jack initialization for a Intel ASoC device and Romain Perier, who unfortunatelly left Collabora a few months ago, added improvements to i.MX and Rockchip devices.
