Linux 6.4 release – Main changes, Arm, RISC-V and MIPS architectures

Linux 6.4 has just been released by Linus Torvalds on the Linux Kernel Mailing List (LKML): Hmm. Final week of 6.4 is done, and we’ve mainly got some netfilter fixes, some mm reverts, and a few tracing updates. There’s random small changes elsewhere: the usual architecture noise, a number of selftest updates, some filesystem fixes (btrfs, ksmb), etc. Most of the stuff in my mailbox the last week has been about upcoming things for 6.5, and I already have 15 pull requests pending. I appreciate all you proactive people. But that’s for tomorrow. Today we’re all busy build-testing the newest kernel release, and checking that it’s all good. Right? Released around two months ago, Linux 6.3 brought us AMD’s “automatic IBRS” Spectre defense mechanism, additional progress on the Rust front with User-mode Linux support (on x86-64 systems only), the NFS filesystem (both the client and server sides) gained support for […]

Snagboot is an open-source cross-vendor recovery tool for embedded targets

Bootlin has just released the Snagboot open-source recovery tool for embedded platforms designed to work with multiple vendors, and currently STMicro STM32MP1, Microchip SAMA5, NXP i.MX6/7/8, Texas Instruments AM335x and AM62x, and Allwinner “sunxi” processors are supported. Silicon vendors usually provide firmware flashing tools, some closed-source binaries, that only work with their hardware. So if you work on STM32MP1 you’d use STM32CubeProgrammer, while SAM-BA is the tool for Microchip processors, NXP i.MX SoC relies on UUU, and if you’ve ever worked on Allwinner processors you’re probably family with sunxi-fel. Bootlin aims to replace all those with the Snagboot recovery tool. The Python tool is comprised of two parts: snagrecover using vendor-specific ROM code mechanisms to initialize external RAM and run the bootloader (typically U-Boot) without modifying any non-volatile memories. snagflash communicates with the bootloader over USB to flash system images to non-volatile memories, using either DFU, USB Mass Storage, or […]

Purism Lapdock kit converts the Librem 5 Linux smartphone into a laptop

Purism has just announced the Lapdock kit to turn their Librem 5 Linux smartphone into a laptop with a 13.3-inch touchscreen display thanks to the NexDock 360 laptop dock. I was a big believer in mobile desktop convergence around 10 years ago, expected to be soon able to use my phone as a computer or laptop with a dock, and it looked like it might have become a reality when Canonical launched the Ubuntu Edge smartphone crowdfunding campaign in 2013. But it turns out demand was not sufficient, and Canonical eventually ended their convergence efforts focusing on profitable IoT and cloud segments instead. But that does not mean there isn’t a niche market and Purism’s Lapdock kit addresses it to some extent. The Lapdock kit is comprised of three parts namely the NexDock 360 laptop dock, a magnetic mount to attach the Librem 5 to the side of the NexDock […]

FOSDEM 2023 schedule – Open-source Embedded, Mobile, IoT, Arm, RISC-V, etc… projects

After two years of taking place exclusively online, FOSDEM 2023 is back in Brussels, Belgium with thousands expected to attend the 2023 version of the “Free and Open Source Developers’ European Meeting” both onsite and online. FOSDEM 2023 will take place on February 4-5 with 776 speakers, 762 events, and 63 tracks. As usual, I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Open Media”, “FOSS Educational Programming Languages devroom”, “RISC-V”, and others. FOSDEM Day 1 – Saturday February 4, 2023 10:30 – 10:55 – GStreamer State of the Union 2023 by Olivier Crête GStreamer is a popular multimedia framework making it possible to create a large variety of applications dealing with audio and video. Since the last FOSDEM, it has received a lot of new features: its RTP & WebRTC stack has greatly improved, Rust […]

Linux 6.1 LTS release – Main changes, Arm, RISC-V and MIPS architectures

Linus Torvalds announced the release of Linux 6.1, likely to be an LTS kernel, last Sunday: So here we are, a week late, but last week was nice and slow, and I’m much happier about the state of 6.1 than I was a couple of weeks ago when things didn’t seem to be slowing down. Of course, that means that now we have the merge window from hell, just before the holidays, with me having some pre-holiday travel coming up too. So while delaying things for a week was the right thing to do, it does make the timing for the 6.2 merge window awkward. That said, I’m happy to report that people seem to have taken that to heart, and I already have two dozen pull requests pending for tomorrow in my inbox. And hopefully I’ll get another batch overnight, so that I can try to really get as […]
