Linux 6.17 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.17 has just been released on LKML: No huge surprises this past week, so here we are, with kernel 6.17 pushed out and ready to go. Below is the shortlog for just the last week – not the full 6.17 release – as usual. It’s not exciting, which is all good. I think the biggest patch in there is some locking fixes for some bluetooth races that could cause use-after-free situations. Whee – that’s about as exciting as it gets. Other than that, there’ the usual driver fixlets (GPU and networking dominate as usual, but “dominate” is still pretty small), there’s some minor random other driver updates, some filesystem noise, and core kernel and mm. And some selftest updates. This obviously means that the merge window for 6.18 will open tomorrow, and I already have four dozen pull requests pending. Thanks to the proactive people – you know who […]

Rockchip RV1126B-P quad-core Cortex-A53 SoC shows up in AI Vision system-on-module

Boardcon MINI1126B-P is a system-on-module (SoM) powered by a Rockchip RV1126B-P 64-bit Arm SoC with a 3 TOPS NPU and a 4K H.264/H.265 encoder and decoder designed for AI vision applications. Rockchip RV1126 quad-core Arm Cortex-A7 camera SoC with a 2 TOPS AI accelerator has been around since 2021, but the RV1126B(-P) is a new chip with four Cortex-A53 cores and a 3 TOPS NPU. The MINI1126B-P SoM is one of the first hardware platforms with the new SoC, and an update to the company’s MINI1126 with the RV1126 SoC, so let’s have a closer look. Rockchip RV1126B-P AI camera SoC Since Boardcon has released the datasheet of the new Rockchip processor, we can list the RV1126B-P key features and specifications: CPU – Quad-core Arm Cortex-A53 up to 1.6 GHz with 32KB L1 I-Cache and 32KB L1 D-Cache, unified 512KB L2 Cache for Cortex-A53 GPU – 2D Graphics Engine VPU […]

Linux 6.16 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.16 on LKML: It’s Sunday afternoon, and the release cycle has come to an end. Last week was nice and calm, and there were no big show-stopper surprises to keep us from the regular schedule, so I’ve tagged and pushed out 6.16 as planned. It’s worth noting that the upcoming merge window for 6.17 is going to be slightly chaotic for me: I have multiple family events this August (a wedding and a big birthday), and with said family being spread not only across the US, but in Finland too, I’m spending about half the month traveling. That means that I will try very hard to get most of the merge window done the first week before my travels start, and I already ended upgiving a heads-up on that to the people who tend to send me the most pull requests.

Rockchip unveils RK3668 10-core Arm Cortex-A730/Cortex-A530 SoC with 16 TOPS NPU, RK182X LLM/VLM co-processor

The Rockchip Developer Conference 2025 (RKDC!2025) is now taking place in Fuzhou, China, with some interesting announcements such as the Rockchip RK3668 10-core Arm Cortex-A730/A530 processor with a 16 TOPS NPU and the RK182X RISC-V co-processor with support for up to 7B parameters LLM (large Language Model)or VLM (Vision Language Model). Rochchip RK3668 10-core Armv9 SoC Let’s have a look at the Rockchip RK3668 SoC, which looks quite similar to the RK3688 SoC unveiled last year, but with some differences. Preliminary Rockchip RK3668 specifications: CPU – 4x Cortex-A730 + 6x Cortex-A530 Armv9.3 cores delivering around 200K DMIPS; note: neither core has been announced by Arm yet GPU – Arm Magni GPU delivering up to 1-1.5 TFLOPS of performance AI accelerator – 16 TOPS RKNN-P3 NPU VPU – 8K 60 FPS video decoder ISP – AI-enhanced ISP supporting up to 8K @ 30 FPS Memory – LPDDR5/5x/6 up to 100 GB/s […]

Linux 6.15 Release – Main changes, Arm, RISC-V and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.15: So this was delayed by a couple of hours because of a last-minute bug report resulting in one new feature being disabled at the eleventh hour, but 6.15 is out there now. Apart from that final scramble, things looked pretty normal last week. Various random small fixes all over, with drivers as usual accounting for most of it. But we’ve got some bcachefs fixes, some core networking, and some mm fixes in there too. Nothing looks particularly scary. And this obviously means that the merge window opens tomorrow as usual, and I see the usual people being proactive and having sent me their pull requests. It’s memorial day tomorrow here in the US, but like the USPS, “neither snow nor rain nor heat nor gloom of night” – nor memorial day – stops the merge window. [ Actually, thinking back […]

Linux 6.14 release – Main changes, Arm, RISC-V, and MIPS architecture

Linus Torvalds has just announced the release of Linux 6.14 on LKML: So it’s early Monday morning (well – early for me, I’m not really a morning person), and I’d love to have some good excuse for why I didn’t do the 6.14 release yesterday on my regular Sunday afternoon release schedule. I’d like to say that some important last-minute thing came up and delayed things. But no. It’s just pure incompetence. Because absolutely nothing last-minute happened yesterday, and I was just clearing up some unrelated things in order to be ready for the merge window. And in the process just entirely forgot to actually ever cut the release. D’oh. So yes, a little delayed for no good reason at all, and obviously that means that the merge window has opened. No rest for the wicked (or the incompetent). Below is the shortlog for the last week. It’s nice and […]
