Linux 6.8 release – Notable changes, Arm, RISC-V, and MIPS architectures

Linux 6.8 release

Linus Torvalds has just announced the release of Linux 6.8 on the Linux kernel mailing list: So it took a bit longer for the commit counts to come down this release than I tend to prefer, but a lot of that seemed to be about various selftest updates (networking in particular) rather than any actual real sign of problems. And the last two weeks have been pretty quiet, so I feel there’s no real reason to delay 6.8. We always have some straggling work, and we’ll end up having some of it pushed to stable rather than hold up the new code. Nothing worrisome enough to keep the regular release schedule from happening. As usual, the shortlog below is just for the last week since rc7, the overall changes in 6.8 are obviously much much bigger. This is not the historically big release that 6.7 was – we seem to […]

Embedded Open Source Summit 2024 schedule – Embedded Linux, Zephyr OS, and Real-time Linux

Embedded Open Source Summit 2024

The Embedded Open Source Summit 2024 (EOSS 2024) will take place on April 16-18 and the Linux Foundation has already announced the schedule with conference sessions, lightning talks, and birds of a feather (BoF) sessions covering embedded Linux, Zephyr OS, and real-time (RT) Linux. While I won’t be attending in person, I still find it interesting to check out the schedule as we may learn more about the current status of embedded Linux. So I’ve created my own little virtual schedule out of the available talks. Tuesday, April 16 – Day 1, Embedded Open Source Summit 2024 9:05 – 9:45 – No, It’s (Still) Never Too Late to Upstream Your Legacy Linux-Based Platforms by Neil Armstrong, Linaro Nearly 7 years ago, Neil already spoke about this subject in Berlin, and it’s still very true. Do you maintain or used to maintain a Linux-based board or SoC off-tree? Then there are […]

Debian 12 and Linux upstreaming for the Qualcomm Snapdragon X Elite SoC

Debian Snapdragon Elite X SoC

When Qualcomm launched the powerful 4.2 GHz Snapdragon X Elite 12-core Arm SoC for “mobile PCs” (better known as laptops), I was surprised they showed benchmarks for both Windows and Linux as in the past, the company focused on Windows only for this type of processor. But at the time we were only shown Geekbench 6.2 results in Linux, so it was not clear what was supported at the time. But a recent post by Abel Vesa, Linaro engineer, explains a fully working Debian 12 image with GPU rendering and WiFi connectivity was ready right before launch and work is now being done to upstream the code to Linux mainline. In this post, he shares the Linux upstreaming plan and provides instructions to install Debian 12 on an official Snapdragon X Elite reference design. Upstreaming will be done in two parts, starting with support for the following: Qualcomm Oryon CPUs Clocks, […]

Linux 6.7 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.7 release

Linus Torvalds has just announced the release of Linux 6.7, following Linux 6.6 LTS a little over two months ago: So we had a little bit more going on last week compared to the holiday week before that, but certainly not enough to make me think we’d want to delay this any further. End result: 6.7 is (in number of commits: over 17k non-merge commits, with 1k+ merges) one of the largest kernel releases we’ve ever had, but the extra rc8 week was purely due to timing with the holidays, not about any difficulties with the larger release. The main changes this last week were a few DRM updates (mainly fixes for new hw enablement in this version – both amd and nouveau), some more bcachefs fixes (and bcachefs is obviously new to 6.7 and one of the reasons for the large number of commits), and then a few random […]

Raspberry Pi 5 gets 5G Modem HAT based on Quectel RM502Q-AE M.2 module

Sixfab 5G Modem Kit for Raspberry Pi 5

Sixfab has just launched a 5G Modem Kit for Raspberry Pi 5 with a Raspberry Pi HAT that takes Quectel RM502Q-AE 5G Sub-6GHz M.2 module working globally (except China), a “patent-pending” internal antenna for Sub-6 frequency bands designed by SixFab, and a USB 3.0 bridge connector.

Qualcomm Snapdragon X Elite SoC benchmarks in Windows and Linux

Snapdragon X Elite reference laptop 23W vs 80W

Qualcomm unveiled the 4.3 GHz 12-core Snapdragon X Elite processor for laptops last week since some bold claims about the performance and efficiency. The company has now released benchmarks for the processor verified by third parties such as Anandtech and Notebookcheck showing the new Snapdragon processor performance is quite amazing with the Arm processor indeed matching Apple, Intel, and AMD high-end chips. What’s more is that the new SoC was tested in both Windows and Linux (using Geekbench 6.2), so in hindsight, I was wrong to say the Snapdragon X Lite would be a Windows-only processor when only seeing the DX12 listed in the specifications… Before we look into the benchmark results, we should note that Qualcomm provided two versions of the Snapdragon X Elite laptop prototype both using active cooling: “demo config A” high-performance system configured to run at an 80W TDP, and a low-power, thinner “demo config B” […]

Qualcomm Snapdragon 8 Gen 3 gains upstream Linux support

Qualcomm Snapdragon 8 Gen3 Android 14 upstream Linux

Linaro has announced upstream Linux support for the newly released Snapdragon 8 Gen 3 mobile platform also codenamed SM8650. The patchsets enable Android 14 AOSP to boot with mainline Linux on Snapdragon 8 Gen 3 hardware using Google SwiftShader CPU-based implementation of the Vulkan graphics API. While there is a lot of buzz around the announcement of the Snapdragon X Elite 12-core Arm processor for laptops in recent days, Qualcomm also introduced its latest premium processor with the Snapdragon 8 Gen 3 Mobile Platform for mobile phones featuring a 3.3 GHz Cortex-X4 core, five Cortex A720 Performance cores, and two Cortex A520 efficiency cores, as well as support for generative AI through AI accelerators. The announcement was made on October 25, and Linaro released the patchsets to the Linux Kernel Mailing List (LKML) on the same day. Android devices are often stuck to an older Linux kernel for their entire […]
