Linux 5.12 – Main Changes, Arm, MIPS and RISC-V Architectures

Linux 5.12 release was expected last Sunday, but Linus Torvalds decided to release one more release candidate, namely Linux 5.12-RC8, to “make sure things are all settled down“, so the latest Linux kernel is now expected this weekend.  Tihs should not yield any significant changes, so we can check what’s new in Linux 5.12, notably with regards to Arm, MIPS, and RISC-V architectures often used in SoC’s found in embedded systems. Around two months ago, the release of Linux 5.11 added support for Intel’s software guard extensions (SGX) and Platform Monitoring Technology (PMT), AMD “Van Gogh” and “Dimgrey cavefish” graphics processors, MIPI I3C host controller interfaces, and much more. Some interesting changes in Linux 5.12 include: Added support for ACRN hypervisor designed for IoT & embedded devices Added support for Playstation DualSense & Nintendo 64 game controllers, as well as Nintendo 64 data cartridges Dynamic thermal power management via a […]

Dakota DR40X9 Wave-2 AC Router Board is Based on Qualcomm QCA4019/QCA4029 WiSoC

Qualcomm is mostly known for its Snapdragon processors for mobile devices and wearables, but the company is also making WiFi chipsets via their (previously) “Atheros” family. Some of their latest WiFi SoCs are IPQ4019 and IPQ4029 (aka QCA4019/QCA4029) Wave-2 802.11ac “Dakota” SoCs for routers, gateways, and access points. We recently covered the official Qualcomm mesh networking devkit powered by IPQ4019 processor, but there are now third parties also offering solutions based on QCA40x9 processor such as Dakota DR40X9 Wave-2 AC router board. Dakota DR40X9 board specifications: SoC (one of the other) Dakota DR4019 -Qualcomm IPQ4019 quad-core Arm Cortex A7 processor @ 717 MHz with 802.11ac Wave 2 WiFi Dakota DR4029 – Qualcomm IPQ4029 quad-core Arm Cortex A7 processor @ 717 MHz with  802.11ac Wave 2 WiFi System Memory- 256MB~512MB DDR Storage – 2MB~32MB NOR Flash, 128MB NAND Flash, microSD card slot Connectivity Wired Dual 10/100/1000Mbps Gigabit Ethernet (RJ45) 1x optional […]
