• Bridging IIO and Input in Linux

  In Linux, the Industrial Input/Output subsystem manages devices like Analog to Digital Converters, Light sensors, accelerometers, etc. On the other hand, the Input subsystem handles keyboards, mice, touchscreens, and any device that has a human interface.

• Melissa Wen: AMD Driver-specific Properties for Color Management on Linux (Part 1)

  TL;DR:

  Color is a visual perception. Human eyes can detect a broader range of colors than any devices in the graphics chain. Since each device can generate, capture or reproduce a specific subset of colors and tones, color management controls color conversion and calibration across devices to ensure a more accurate and consistent color representation. We can expose a GPU-accelerated display color management pipeline to support this process and enhance results, and this is what we are doing on Linux to improve color management on Gamescope/SteamDeck. Even with the challenges of being external developers, we have been working on mapping AMD GPU color capabilities to the Linux kernel color management interface, which is a combination of DRM and AMD driver-specific color properties. This more extensive color management pipeline includes pre-defined Transfer Functions, 1-Dimensional LookUp Tables (1D LUTs), and 3D LUTs before and after the plane composition/blending.

  The study of color is well-established and has been explored for many years. Color science and research findings have also guided technology innovations. As a result, color in Computer Graphics is a very complex topic that I’m putting a lot of effort into becoming familiar with. I always find myself rereading all the materials I have collected about color space and operations since I started this journey (about one year ago). I also understand how hard it is to find consensus on some color subjects, as exemplified by all explanations around the 2015 online viral phenomenon of The Black and Blue Dress. Have you heard about it? What is the color of the dress for you?

• Linux Plumbers Conference: VFIO/IOMMU/PCI MC CFP

  On behalf of the PCI sub-system maintainers, we would like to invite everyone to join the VFIO/IOMMU/PCI micro-conference (MC) this year.

  We are hoping to bring together, both in person and online, everyone interested in the VFIO, IOMMU, and PCI space to talk about the latest developments and challenges in these areas.

• OpenDaylight: Celebrating 10 Years of the Most Popular Open Source SDN Controller

  This year marks the 10-year anniversary of Open Daylight, so we at LF Networking wanted to spotlight how it has grown to be the most popular open source SDN controller, a top important open source project in networking, and how it will continue to evolve in the future.
