Linux 6.16 was released last Sunday, and as usual LWN provides the best coverage of what’s new: part 1 and part 2, as well as the KernelNewbies.org page for this release.

This time around, the engineers at Bootlin contributed 89 patches to the 6.16 release, but also as maintainers, they reviewed/merged 117 patches from other contributors!

Linux 6.11 has been released a week ago, the day before Open Source Summit Europe started, but as a large part of the Bootlin team was attending this conference and the immediately following Linux Plumbers conference, we are only posting now our usual blog post about our Linux 6.11 contributions.

As usual, we warmly recommend our readers to look at the articles from LWN.net covering the 6.11 merge window (part 1, part 2) to get a good high-level overview of the major new features and hardware support added in 6.11. CNX-Software also has a useful article on the 6.11 features relevant for embedded platforms.

From a Bootlin perspective, we contributed a total of 120 commits in this release, making us the 19th contributing company by number of commits, worldwide, according to the statistics. In addition to those 120 commits authored by Bootlin engineers, we reviewed and merged 76 patches from other contributors, as part of the Linux kernel maintainer role of several Bootlin engineers (Alexandre Belloni as the RTC and I3C maintainers, Miquèl Raynal as the MTD co-maintainer, and Grégory Clement as the Marvell platform maintainer).

Linux 6.10 was released last Sunday, following its now well-known release cadence. As usual, head over to LWN.net to have some good summary of the important features merged in this kernel release: part 1 and part 2.

LWN also published an article on statistics of the 6.10 release cycle, and Bootlin shows up in the most active employers by changed lines, with 7746 lines changed by Bootlin engineers. According to ths Kernel Patch Statistics site, we contributed 110 changes, putting us as the 19th contributing company (counting “Unknown” and “Hobbyists” as companies).

Also, in addition to the 110 patches we contributed, some of our engineers are also maintainers of different subsystems, and as such they review/merge patches contributed by others:

• Alexandre Belloni reviewed/merged 19 patches for the I3C and RTC subsystems which he maintains
• Grégory Clement reviewed/merged 14 patches for the Marvell ARM and ARM64 platforms that he maintains
• Miquèl Raynal reviewed/merged 12 patches for the MTD subsystem, which he co-maintains

The Linux 6.8 kernel has been released on March 10 by Linus Torvalds. As usual, we definitely recommend the coverage by LWN of the merge window for this release cycle to get a good grasp on the most important new features: first half and second half. Some work from Bootlin is briefly mentioned in those articles, such as the support for Lantiq PEF2256 (FALC56) framers, Lantiq PEF2256 (FALC56) pin controllers, and Techwell TW9900 video decoders.

With a total of 135 commits contributed by Bootlin engineers during this release cycle, we have been much more active than for the previous 6.7 release. This allows Bootlin to show in the recently published Development statistics for 6.8, as the 17th contributing company by number of commits, and 13th contributing company by number of changed lines.

Linux 6.6 was released yesterday, so this is the time for our usual blog post about our contributions to this release. Before that, to get an overall idea of what went into Linux 6.6, we recommend reading the articles from LWN.net covering the Linux 6.6 merge window: part 1 and part 2. The KernelNewbies page is perhaps a little bit less rich than it used to be, but still relevant.

On our side, this time around we contributed 68 changes to this release:

• Alexandre Belloni, as the RTC subsystem maintainer, submitted a few asorted patches touching various drivers in this subsystem
• Alexis Lothoré pushed some patches extending the rzn1-a5psw Ethernet switch driver with VLAN support and port_bridge_flags support. These patches were initially written by Clément Léger but had not been accepted until now.
• Hervé Codina got his audio-iio-aux driver merged, which allows the ASoC subsystem (for audio devices) to use IIO devices, such as a potentiometer. This came together with a number of fixes/improvements in the IIO subsystem. Hervé also fixed some reference counting issues in several I2C mux drivers.
• Miquèl Raynal pushed to the finish line a patch written several years ago by Bootlin engineer Kamel Bouhara, who hadn’t been accepted until now. This patch adds a sysfs interface that allows to retrieve the reset reason on Microchip ARM platforms
• Luca Ceresoli fixed some issues in two DRM panel drivers and also fixed a regression in the NVidia Tegra camera interface driver
• Miquèl Raynal did a number of different, unrelated, contributions:
  • support for the EDT ET028013DMA display panel to the existing sitronix-st7789v driver, which required quite a few preparation changes
  • fix a clock polarity issue in the DRM driver for the display controller used in Microchip ARM platforms
  • improve many small aspects of the qcom NAND controller driver
  • improve the handling of nvmem layouts in the nvmem subsystem
  • fix an issue in the SJA1000 CAN controller driver that would cause the HW to stall after an overrun on some platforms
• Paul Kocialkowski contributed a few small asorted fixes in the media subsystem documentation
