The Linux kernel could soon be 50 to 80% faster to build

Linux kernel build faster

The Linux kernel takes around 5 minutes (without modules) to build on an Intel Core i5 Jasper Lake mini PC with 16 GB RAM and a fast SSD based on our recent review of Beelink GTi 11 mini PC. Kernel developers may have to build for different targets and configurations, plus all modules so the build times may add up. While it is always possible to throw more hardware to quicken the builds, it would be good if significantly faster builts could be achieved with software optimizations. That’s exactly what Ingo Molnar has been working on since late 2020 with his “Fast Kernel Headers” project aiming to eliminate the Linux kernel’s “Dependency Hell”. At the time he aimed for a 20% speedup, but a little over one year later, the results are much more impressive with 50 to 80% faster builds depending on the target platform (x86-64, arm64, etc…) and […]

Year 2021 in review – Top 10 posts and statistics

cnx software happy new year 2022

As per tradition, we’ll look back at what happened during the year in the last post, and see what 2022 may have in store, plus the usual statistics from CNX Software website. The biggest story of 2021 has to be the worsening of semiconductors shortages with extremely long lead times, prices of some components going up multiple folds, constant complaints on Twitter about availability and prices. I think I even saw a website, hopefully misconfigured, showing an estimated availability of a specific STM32 MCU in 2037. This also gave rise to opportunities and board redesigns, with MotorComm Ethernet chips replacing some Realtek chips in SBCs such as NanoPi R2C and  Orange Pi R1S Plus LTS, and CH9102F showing up as a replacement for CP2104 in some IoT boards. We also got some interesting Arm processors, but sadly the high-expected Rockchip RK3588 got delayed by another year, although it’s getting really […]

Sipeed Lichee RV RISC-V module gets $5+ carrier board with HDMI and USB ports, optional WiFi

Sipeed Lichee RV Starter Kit

Sipeed introduced the Lichee RV Allwinner D1 Linux RISC-V board going for just $17 with 512MB RAM last month. While with a USB-C port it could be used as a standalone part, its dual M.2 connector makes it more like a module and we noted a tiny carrier board was in the works at the time. The baseboard is now available and known as the Lichee RV Dock adding HDMI and USB ports, as well as a 40-pin GPIO header for just $5, or $8 if you’d like to get Wi-Fi 4 and Bluetooth 4.2 connectivity through a Realtek RTL8723DS module. Sipeed Lichee RV Dock specifications: Supported system-on-module (SoM) – Lichee RV module with Allwinner D1 RISC-V processor @ 1 GHz, 512MB DDR3, MicroSD card slot, and USB Type-C OTG port Storage – Optional SPI flash Display interfaces HDMI port up to 4Kp30 Optional RGB interface for up to 720p30 […]

OS and Memory Impact on Mini PC Gaming Performance

OS GPU memory

This article looks at what the effect of running a different operating system or having more memory has on similarly spec’d Intel and AMD mini PCs when gaming. Note: This article has been updated and corrected as a result of reader feedback and additional testing. It was inspired by having built and tested a pseudo ‘Steamdeck’ running Manjaro on an AMD-based mini PC with 16GB of memory, which made me wonder what the performance would be like using Windows 11. Initial results were surprising because Windows appeared much slower. As I’d previously heard of performance improvements when using 64GB of memory I swapped out the currently installed 16GB memory and immediately saw improved results. As I’d never observed such a dramatic performance increase on Intel mini PCs just through increasing the memory I decided to explore further by testing gaming performance on similar Intel and AMD mini PCs when using […]

Beelink GTi11 review – Part 2: Ubuntu 20.04 on an Intel Core i5-1135G7 mini PC

Previously I reviewed Beelink’s new GTi11 Intel Tiger Lake mini PC running Windows 11, so in this part, I will cover Ubuntu 20.04. Hardware Recap The GTi11 is a 168 x 120 x 39mm (6.61 x 4.72 x 1.54 inches) actively cooled mini PC and the review model has an i5-1135G7 Intel Tiger Lake quad-core 8-thread 2.50 GHz Core processor boosting to 4.20 GHz with Intel’s Xe Graphics. The review model also includes a 500GB M.2 2280 NVMe PCIe Gen 3.0 SSD drive initially with Windows 10 Pro installed but now successfully upgraded to Windows 11 Pro, two sticks of 8GB DDR4 3200 MHz memory, a soldered WiFi 6 (or 802.11ax) Intel AX201 chip and dual 2.5Gb Ethernet ports. The specifications list four of the USB ports as 3.0 so I retested them on Ubuntu using a Samsung 980 PRO PCle 4.0 NVMe M.2 SSD housed in an ‘USB to […]

(Some) TP-Link routers enable hidden networks by default. Is that an issue?

TP-Link Hidden Networks Onemesh

There are plenty of security issues with many routers including firmware that is seldom upgraded, opened (telnet) port with the default password, and the list could go on. But Jahed Ahmed recently wrote about an issue I had not heard of before: his TP-Link router shows two hidden networks in 2.4 GHz and 5 GHz bands that he only discovered after running WiFi Analyzer on his phone. He did not enable those networks, so that was the default configuration from the firmware. That could potentially pose a security risk, contributes to WiFi spam, and Jahed also mentions a waste of energy although the extra power consumption is probably limited, even when scaled to millions of users. So why is TP-Link doing this? Apparently for their OneMesh mesh wireless network system and device including range and powerline extenders that users may want to use. Other users have been reporting this issue […]

Dual 10GbE router supports WiFi 6 (AX3600)

Dual 10GbE router

We’ve just written about a Qualcomm IPQ8072A SBC/reference design with two 10GbE ports and WiFi 6 that’s good for companies wanting to design their own system, but if you’re looking for a dual 10GbE router there are already options, notably QNAP QHora-310W sold for $329 on Amazon. But another dual 10GbE router with WiFi 6 was brought to my attention from a company I had never heard of. Acelink BR-6889AX is a WiFi 6 “AX3600 4T4R 10GE Router” based on Qualcomm IPQ8072A processor that’s suitable for the connected home and office networks including WFH use cases. Acelink BR-6889AX specifications: SoC – Qualcomm Hawkeye IPQ8072A quad-core Cortex A53 @ 2.2GHz with dual-core multi-threaded network accelerator, In-line security engine System Memory – 512 MB DDR3 (2x 256MB) Storage – 4MB SPI NOR flash, 128MB NAND flash Networking Wired 2x 100/1,000/2,500/5,000/10,000Mbps BASE-T Ethernet (RJ45) ports with Link/Act, Speed LED 3x 10/100/1,000Mbps BASE-T Ethernet […]
