OpenBSD 7.0 adds 64-bit RISC-V, improves Apple Arm silicon support

OpenBSD 7.0

OpenBSD 7.0, the 51st release of the UNIX-like operating system, was outed on October 14, 2021, with the introduction of 64-bit RISC-V support for HiFive Unmatched and PolarFire SoC Icicle Kit boards, as well as further improvements to ARM64 targets, notably for Apple Silicon Macs, although it’s not quite ready for general use yet. You’ll find the complete list of new features and updates on the OpenBSD website, but here are some of the highlights: New platforms – OpenBSD 7.0 add 64-bit RISC-V support Extended platforms arm64 Improvements to Apple Silicon Macs support USB 3, NVMe storage, GPIO driver, power management, etc… Enabled LEDs for the LAN7800 chip as found on the Raspberry Pi 3 Model B+. Added Type-C PHY controller found on the Rockchip RK3399. Implemented multicast support to Marvell ARMADA chips Various other changes to mips64, amd64, armv7, powerpc64 Kernel improvements Enabled dynamic tracker (dt) for GENERIC kernels […]

Linux 5.13 Release – Notable changes, Arm, MIPS and RISC-V architectures

Linux 5.13 release

Linus Torvalds has just announced the release of Linux 5.13: So we had quite the calm week since rc7, and I see no reason to delay 5.13. The shortlog for the week is tiny, with just 88 non-merge commits (and a few of those are just reverts). It’s a fairly random mix of fixes, and being so small I’d just suggest people scan the appended shortlog for what happened. Of course, if the last week was small and calm, 5.13 overall is actually fairly large. In fact, it’s one of the bigger 5.x releases, with over 16k commits (over 17k if you count merges), from over 2k developers. But it’s a “big all over” kind of thing, not something particular that stands out as particularly unusual. Some of the extra size might just be because 5.12 had that extra rc week. And with 5.13 out the door, that obviously means […]

Project Connected Home over IP (CHIP) Working Group is Backed by Google, Apple, Amazon, and the Zigbee Alliance

Project Connected Home over IP

Amazon, Apple, Google, and Zigbee Alliance have partnered to create Project Connected Home over IP (CHIP) working group aiming to develop a royalty-free, Smart Home standard to increase compatibility among products, and with security at the forefront. The new standard will be separate from Zigbee 3.0 / Pro, and Zigbee Alliance board member companies such IKEA, Legrand, NXP Semiconductors, Resideo, Samsung SmartThings, Schneider Electric, Signify (formerly Philips Lighting), Silicon Labs, Somfy, and Wulian will also join the CHIP working group and contribute to the project. The standard specified by Project Connected Home over IP will rely on existing technology from the networking layer including TCP/UDP transport protocol, IPv6 network and various physical & media standards such as WiFi, Ethernet, Bluetooth LE, Cellular, 802.15.4 and others. Instead, it will define what happens at the application layer level with the following points of focus: End-to-end data security and privacy among in-home and […]

$99 Mira Prism Augmented Reality Headset Works with your Phone

We’ve seen many virtual reality headsets launched in the last year or so, even through the technology and ecosystem still needs to be improved to offer an acceptable user experience, but so far I have not seen augmented reality headset that combines 3D real and virtual worlds into a single screen. I was pretty enthusiastic about augmented reality technology when I first heard about in 2010,  but fast forward to 2017, I’m not using any such apps myself, with the most popular AR app possibly being Pokemon Go game launched last year, and apps like the upcoming AR Measure look quite useful. Augmented reality normally works by holding your phone into your hands and the camera, but Mira Prism will change that it’s meant to be worn like a virtual reality headset and relies on a phone (iPhone only for now) to mix both worlds right in front of your […]

Apple Opens HomeKit Accessory Protocol Specification to Non-Commercial Projects

HomeKit is a software framework that allows Apple users to control smart devices with their iPhone or iPad. But so far, you had to become an MFI licensee to design a HomeKit compatible device, you product had to be tested by Apple, and – according to a story on Hackster.io – also required a special cryptographic chip for authentication. Developers creating commercial devices still need to become an MFI license, but Apple has now opened HomeKit Accessory Protocol Specification for non-commercial projects, meaning you can now use the Framework on Arduino, ESP8266 boards,  Raspberry Pi, and other development boards using software authentication. You could already use HomeKit on Raspberry Pi board previously using HomeBridge, but the advantage now is that you don’t need to breach Apple’s terms and conditions, and you can talk directly to your phone without the need for a bridge. If you want the specifications got to […]

Samsung Exynos 8890 Processor with Custom Exynos M1 and ARM Cortex A53 Cores Benchmarked

When Samsung announced Exynos 8890 processor, it promised 10% lower consumption and 30% high performance compared to Exynos 7 Octa. The company also said it make its own custom ARMv8 cores for the new, but at the time details were limited. Anandtech has now published more information, and Exynos 8890 octa-core processor will make use of four Exynos M1 custom cores combined with four low power ARM Cortex A53 cores, combined with a Mali-T880MP12 GPU. Exynos 8890 key features: Low power cores – 4x ARM Cortex A53 cores @ 1.586GHz High performance cores – 2x Exynos M1 @ 2.60 GHz, 2x Exynos N1 @ 2.29 GHz; If 4 cores are running at the same time: 2.29 GHz maximum Memory – 2x 32-bit LPDDR4 @ 1794MHz; 28.7GB/s bandwidth GPU – Mali-T880MP12 @ 650 MHz Manufacturing process – Samsung 14nm LPP Now that Samsung Galaxy 7 has been announced with Exynos 8890 […]

Nvidia Shield Android TV vs Apple TV vs Roku 3 vs Fire TV vs Nexus Player – Video Capabilities and Features Comparison

Since Nvidia released the Shield Android TV box, I’ve heard several people saying Nvidia raised the bar and even disrupted the TV box market by bringing a powerful HTPC and gaming console to the market for just $199. The company has now released OTA 2.0 firmware that improves HTPC capabilities, including under Kodi and Plex, and the box supports for 10-bit HEVC, H.264, and VP9 @ 4K, and audio pass-through for HD audio codecs such as Dolby TrueHD and DTS-HD Master. As part of the release announcement, Nvidia also compared the Shield TV media capabilities to the ones of other US centric media players, namely Apple TV (2015), Roku 3, Amazon Fire TV (2015), and Nexus Player. Since it comes from Nvidia, it was also going to show the Shield TV in a good light, but I’m very surprised to see that Apple, Amazon, Google, and Roku would ship a […]

Technology Patent Wars Infographic

You may have heard of patent fights between Samsung and Apple with ensuing delays in product launches, or even the recent Oracle vs Google patent fight. Visual.ly has created an infographic about the rampant patent wars in the US Tech Industry which shows just how messy patent fights in US courts are. This must really be a boon for lawyers. The external ring of the chart shows the alliances or patent purchases between companies. The busiest companies on the patent war front seem to be Apple, ZTE and Microsoft. Google is by far the company who bought the most existing patents mainly from Motorola Mobility (17,000 patents) and IBM (2,094 patents). Via visually.
