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 […]

Sipeed NanoCluster palm-sized cluster board takes up to 7 system-on-modules

Sipeed NanoCluster is a palm-sized cluster board with seven slots for Raspberry Pi CM4/CM5, Sipeed LM3H (Allwinner H618), and/or Sipeed M4N (AXera AX650N AI SoC) system-on-modules, and other compatible SoMs might also work. The board handles inter-module communication through an 8-port RISC-V-based Gigabit switch, and supports up to 60W USB-C PD or PoE (optional) power. The NanoCluster also offers independent UART and power control for each module, and is suitable as an entry-level/educational platform for HomeLab users working with distributed computing, Kubernetes, Docker, and edge computing. Sipeed NanoCluster specifications: Supported SOMs Raspberry Pi CM4 – Broadcom BCM2711 quad-core Cortex-A72 SoC @ 1.5 GHz with VideoCore VI GPU, 1GB to 8GB RAM, up to 64GB eMMC flash (optional) Raspberry Pi CM5 – Broadcom BCM2712 quad-core Cortex-A76 SoC @ 2.4 GHz with VideoCore VII GPU, 1GB to 16GB RAM, up to 64GB eMMC flash (optional) Sipeed LM3H – Allwinner H618 quad-core Cortex-A53 […]

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.

Allwinner H135 RISC-V multimedia SoC is made for projectors and KVM solutions

The Allwinner H135 is a 64-bit RISC-V multimedia SoC officially designed for low-cost projectors. However, support for HDMI Rx and MJPEG 1080p60 video encoding also makes it suitable for entry-level KVM (Keyboard, Video, and Mouse) solutions. The H135 is based on the XuanTie C906 core, supports up to 256MB DDR2/DDR3/DDR3L, integrates a 1080p60 H.265/H.264 video decoder, MIPI DSI, dual-channel LVDS, and RGB888 display interfaces, and plenty of peripherals such as USB, SDIO, UART, SPI, PWM, GPIO, and more. Allwinner H135 specifications: CPU – XuanTie C906 RISC-V CPU with 64 KB I-cache + 64 KB D-cache Display Engine Allwinner Awonder1.1 Lite post processing Keystone correction in online mode and [-360°,360°] rotation in offline mode De-interlace (DI) up to 1920×1080 @ 60fps G2D hardware accelerator with rotate and mixer functions VPU Video decoding – H.265, H.264, H.263, MPEG-1/2/4, and VC-1 up to 1080p60 Image decoding – JPEG up to 1080p60 Video encoding […]

Quantum Tiny Linux SBC features an Allwinner H3 SoC, WiFi, a small Display, and more

Made by a Chinese engineer and content creator Zhihui Peng, the “Quantum Tiny Linux Development Kit” is a small SBC that’s smaller than an ID photo, powered by an Allwinner H3 SoC, and equipped with 512MB of RAM and a 16GB eMMC flash. It’s a design with a 31x22mm CPU module with an M.2 edge connector and a 40x35mm carrier board with a microSD card slot, WiFi 4 and Bluetooth 4.0 wireless module, a TFT display, two USB 2.0 ports, a 6-axis motion sensor, and a few buttons. Quantum Tiny specifications: Quark-N SoM SoC – Allwinner H3 CPU – Quad-core Cortex-A7 @ 1GHz GPU – Arm Mali400 MP2 GPU System Memory – 512MB LPDDR3 RAM Storage – 16GB eMMC flash M.2 edge connector with Ethernet, SPI, I2C, UART, Reusable GPIO, MIC, LINEOUT Dimensions – 31 x 22mm (6-layer PCB) Temperature Range – 0 to 80°C Atom-N Expansion Board M.2 socket […]

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 […]

Walnut Pi 2B is an Allwinner T527 octa-core SBC with Raspberry Pi 5 form factor and interfaces

Walnut Pi 2B is a single board computer (SBC) powered by an Allwinner T527 octa-core Cortex-A55 SoC with a built-in 2 TOPS AI accelerator that closely follows the Raspberry Pi 5 design for compatibility with most HAT+ expansion boards and accessories. The Walnut Pi 2B SBC ships with 1GB to 4GB LPDDR4 RAM, an optional 32GB eMMC flash, and features a microSD card slot, gigabit Ethernet, four USB ports, a WiFI and Bluetooth module, MIPI DSI/CSI connectors, and the same PCIe FFC connector as found on the Raspberry Pi 5, and a 40-pin GPIO. One of the most obvious differences is that it only comes with one micro HDMI port instead of two on the Pi 5. Let’s check out the specifications to find other changes. Walnut Pi 2B specifications: SoC – Allwinner T527 CPU Octa-core Arm Cortex-A55 processor with four cores @ 1.80 GHz and four cores @ 1.42GHz […]

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 […]
