Linux 5.6 was released last Sunday. As usual, LWN has the best coverage of the new features merged in this release: part 1 and part 2. Sadly, the corresponding KernelNewbies page has not yet been updated with the usual very interesting summary of the important changes.
Bootlin contributed a total of 95 patches to this release, which makes us the 27th contributing company by number of commits, according to the statistics. The main highlights of our contributions are:
- Our work on supporting hardware-offloading of MACsec encryption/decryption in the networking subsystem and support for this offloading for some Microchip/Vitesse PHYs has been merged. See our previous blog post for more details about this work done by Bootlin engineer Antoine Ténart
- As part of our work on the Rockchip PX30 system-on-chip, we contributed support for LVDS display on Rockchip PX30, and support for the Satoz SAT050AT40H12R2 panel. This work was done by Miquèl Raynal
- Alexandre Belloni as the RTC maintainer did his usual number of cleanup and improvements to existing RTC drivers
- We did a number of small contributions to the Microchip AT91/SAMA5 platform: support for the Smartkiz platform from Overkiz, phylink improvements in the macb driver, etc.
- Paul Kocialkowski improved the Intel GMA 500 DRM driver to support page flip.
- Paul Kocialkowski contributed support for the Xylon LogiCVC GPIO controller, which is a preliminary step to contributing the Xylon LogiCVC display controller support. See our blog post on this topic.
In addition to being contributors, a number of Bootlin engineers are also maintainers of various parts of the Linux kernel, and as such:
- Alexandre Belloni, as the RTC subsystem maintainer and Microchip platforms co-maintainer, has reviewed and merged 55 patches from other contributors
- Miquèl Raynal, as the MTD co-maintainer, has reviewed and merged 21 patches from other contributors
- Grégory Clement, as the Marvell EBU platform co-maintainer, has reviewed and merged 12 patches from other contributors
