Bootlin open-source contributions for the week of Apr 15 to Apr 20. Half of the team was attending the Embedded Linux Conference this week, so we were obviously somewhat less active. - Köry Maincent posted a v8 and then v9 of his series adding Power over Ethernet support, and this v9 was finally merged! https://lnkd.in/etrQbm6r. It means net-next has basic PoE support, and it should land in Linux 6.10. We will now work on more advanced features - Romain Gantois submitted a v3 of his patch series enabling the GMAC1 Ethernet controller on Renesas Electronics RZN1, https://lnkd.in/ebt8CrTN - Luca Ceresoli was giving a talk at ELC on the DAPM subsystem of the kernel. So he sent a series improving the documentation for DAPM in the kernel: https://lnkd.in/eVNrmDtF, and a patch series introducing a new tool called dapm-graph, inspired by the mostly unmaintained and out-of-tree vizdapm tool: https://lnkd.in/eVNrmDtF. Very useful for people doing audio on embedded devices! - Thomas Richard continued his work on suspend/resume support for some Texas Instruments platform: a new series for the PHY drivers, https://lnkd.in/erXSedbT, and a 5th iteration of the PCIe driver suspend/resume support: https://lnkd.in/ez9A5AZb - Michael Opdenacker started working on unittests for his bitbake prserv improvements, and submitted a RFC series asking for some feedback: https://lnkd.in/eQ5q6e8E - Alexis Lothoré submitted a series of patches to fix MAC address handling in the Microchip Technology Inc. WILC driver: https://lnkd.in/e_uR--M3 - Thomas Richard submitted a patch adding suspend/resume support for the Texas Instruments thermal driver: https://lnkd.in/e4jxgH2D - Alexis Lothoré sent an update of the Buildroot pppd package: https://lnkd.in/eMqkFdME - Kamel BOUHARA sent a v10, and then v11 of his TouchNetix Axiom touchscreen driver: https://lnkd.in/eziMFH-4 We wish everyone a good week-end, see you next week for more open-source contributions!

🚀 [𝐀𝐑𝐓𝐈𝐂𝐋𝐄] 𝐏𝐡𝐨𝐭𝐨𝐧𝐢𝐜𝐬: 𝐀 𝐒𝐨𝐥𝐮𝐭𝐢𝐨𝐧 𝐭𝐨 𝐒𝐩𝐚𝐜𝐞 𝐑𝐚𝐝𝐢𝐨 𝐂𝐨𝐧𝐠𝐞𝐬𝐭𝐢𝐨𝐧 With over 26,100 small satellites expected in the next decade, radio frequency congestion in space is a growing concern. In his article "𝐏𝐡𝐨𝐭𝐨𝐧𝐢𝐜𝐬 𝐜𝐚𝐧 𝐫𝐞𝐥𝐢𝐞𝐯𝐞 𝐫𝐚𝐝𝐢𝐨 𝐜𝐨𝐧𝐠𝐞𝐬𝐭𝐢𝐨𝐧 𝐢𝐧 𝐬𝐩𝐚𝐜𝐞 𝐭𝐞𝐥𝐞𝐜𝐨𝐦𝐦𝐮𝐧𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬," Jean-Francois Morizur, CEO of Cailabs highlights how photonics, particularly optical communication, can be a game-changer. Laser-based communication offers immunity to interference, increased security, and 100x faster data speeds. At Cailabs, we're pioneering multi-plane light conversion (MPLC) technology to overcome atmospheric challenges and unlock the potential of laser communications. A hybrid approach using both radio and laser will ensure reliable space communications. 📰 Read the article to learn more about how photonics can address space radio congestion 👉 https://lnkd.in/dq5J5xrb #SpaceTech #Photonics #OpticalCommunication

The META-HiLight project has been recognized with 2nd place for "Best Innovation by a Multilateral Project, Organisation, or Company" at the 20th anniversary of SPIE, the international society for optics and photonics in Strasbourg. This project is a testament to the power of collaboration, bringing together the University of Southern Denmark, SINTEF, and the University of Oulu. By developing novel diagnostic techniques that leverage the unique properties of light polarization, META-HiLight is pushing the boundaries of medical diagnostics. The goal? To make disease detection quicker and more detailed, particularly for conditions like cancer, through advanced, chip-based optical technologies. This recognition highlights the innovative approach and underscores the potential of international cooperation in transforming healthcare technologies. #PhotonicsEurope #Innovation #HealthcareTechnology #MedicalDiagnostics #Collaboration #Engineering #METAHiLight #SDU #SINTEF #UniversityOfOulu #SPIE

Last week we looked about memory mappings in the Linux kernel. We've finally seen how the mmap system call gets you mapped memory. We've also seen how the /proc/<pid/maps entries are created. https://lnkd.in/dTWhbFbY

Let's have a look at the open-source contributions from Bootlin engineers from last week, with quite a few things once again. Most of it are Linux kernel contributions, but there's also some Yocto Project project and some Buildroot work as well: - Romain Gantois submitted the 7th iteration of his patch series adding support for the GMAC1 Ethernet interface in the Renesas Electronics RZN1 processor, and this iteration got merged and will be part of Linux 6.10! See https://lnkd.in/e_YqBb6U - While at the Linux Display Hackfest organized in Spain by Igalia, Louis Chauvet continued working on... graphics topics, and submitted a v7 and then v8 of his series improving the Linux kernel VKMS to support YUV pixel formats (https://lnkd.in/ecjPTRie), and he also sent a first iteration of a series adding support for several other plane formats: https://lnkd.in/eBNE-pkn - Herve Codina fixed a bug in the lan966x network driver: https://lnkd.in/eAnKqYyi - Grégory Clement sent a v2 of the patch series adding initial support for the Mobileye EyeQ6H processor: https://lnkd.in/evgM3Yjb - Thomas Petazzoni contributed two changes to Buildroot: one to fix hash of some Cargo-fetched packages, one to switch to Gitlab as the issue tracker: https://lnkd.in/e4dY-VCg, https://lnkd.in/e-5pNkWR - João Marcos Costa fixed an issue in the OpenEmbedded/Yocto CI machinery: https://lnkd.in/ecD6B5eU - Alexis Lothoré continued his work on the Microchip Technology Inc. WILC driver: https://lnkd.in/eB6ZV_hp - Thomas Richard posted a v6 of his series adding suspend/resume support for the PCIe interface on recent Texas Instruments processors - Richard Genoud added power management support to the TPS6594 driver: https://lnkd.in/eNS2Htf4 - Miquèl Raynal submitted a v2 of his NAND early identification fixes: https://lnkd.in/e5udNp4m - Thomas Bonnefille submitted a v2 of his series adding I2C support for the Alibaba Group TH1520 RISC-V processor: https://lnkd.in/eS6dgP-7
