The "Chinese EPYC" Hygon Dhyana CPU Support Still Getting Squared Away For Linux

Filed under
Linux
Hardware

Back in June is when the Linux kernel patches appeared for the Hygon Dhyana, the new x86 processors based on AMD Zen/EPYC technology licensed by Chengdu Haiguang IC Design Co for use in Chinese data-centers. While the patches have been out for months, they haven't reached the mainline kernel quite yet but that might change next cycle.

The Hygon Dyhana Linux kernel patches have gone through several revisions and the code is mostly adapting existing AMD Linux kernel code paths for Zen/EPYC to do the same on these new processors. While these initial Hygon CPUs appear to basically be re-branded EPYC CPUs, the identifiers are different as rather than AMD Family 17h, it's now Family 18h and the CPU Vendor ID is "HygonGenuine" and carries a new PCI Express device vendor ID, etc. So the different areas of the kernel from CPUFreq to KVM/Xen virtualization to Spectre V2 mitigations had to be updated for the correct behavior.

A $1, Linux-Capable, Hand-Solderable Processor and Open Source Paramotor Using Quadcopter Tech

  • A $1, Linux-Capable, Hand-Solderable Processor

    Over on the EEVblog, someone noticed an interesting chip that’s been apparently flying under our radar for a while. This is an ARM processor capable of running Linux. It’s hand-solderable in a TQFP package, has a built-in Mali GPU, support for a touch panel, and has support for 512MB of DDR3. If you do it right, this will get you into the territory of a BeagleBone or a Raspberry Pi Zero, on a board that’s whatever form factor you can imagine. Here’s the best part: you can get this part for $1 USD in large-ish quantities. A cursory glance at the usual online retailers tells me you can get this part in quantity one for under $3. This is interesting, to say the least.

  • Open Source Paramotor Using Quadcopter Tech

    But not always. The OpenPPG project aims to create a low-cost paramotor with electronics and motors intended for heavyweight multicopters. It provides thrust comparable to gas paramotors for 20 to 40 minutes of flight time, all while being cheaper and easier to maintain. The whole project is open source, so if you don’t want to buy one of their kits or assembled versions, you’re free to use and remix the design into a personal aircraft of your own creation.

    It’s still going to cost for a few thousand USD to get a complete paraglider going, but at least you won’t need to pay hangar fees. Thanks to the design which utilizes carbon fiber plates and some clever hinges, the whole thing folds up into a easier to transport and store shape than traditional paramotors with one large propeller. Plus it doesn’t hurt that it looks a lot cooler.

  • Aceinna launches open-source GNSS+IMU development kit for drones, robots

    MEMS-based sensing solutions company Acienna announces OpenIMU, a professionally supported, open-source GPS/GNSS-aided inertial navigation software stack for low-cost precise navigation applications.

    Integrating an inertial measurement unit (IMU)-based sensor network will greatly improve its navigation and self-location capabilities, Acienna said.

    It is aimed at developing autonomously guided vehicles for industrial applications, autonomous cars, factory or industrial robots, drones, remotely operated underwater vehicle (ROV) or any kind of smart machine that needs to move fast or slow, on land, in the air or in water.

Howchip has launched a sandwich-style, Nano-ITX form factor “ExSOM-8895 DVK” that runs Android 7.0 and Linux 4.4.13 on Samsung’s octa-core Exynos 8895 SoC with 4GB DDR4, dual UFS 2.1 storage interfaces, and MIPI-DSI and -CSI.

A Chinese firm called Howchip, owned by Unibest, has launched an Android Nougat Development Platform. The ExSOM-8895 DVK showcases Samsung’s Exynos 8895, an octa-core SoC that is available on EMEA-bound versions models of the primarily Snapdragon 835 based Galaxy S8 phone. The 120 x 120mm Nano-ITX form-factor board integrates an unnamed 70 x 50mm compute module that houses the Exynos 8895 and runs Android 7.0 with Linux kernel 4.4.13.

Last week SiFive published their HiFive Unleashed open-source boot-loader code for this first RISC-V SoC on their Linux-friendly development board. This code being open-sourced has already helped improve the support for the FU540 SoC within Coreboot.

The code open-sourced last week by SiFive allows for a fully open-source boot process after this first RISC-V developer board received some criticism for some of its initialization code being closed-source, namely around the SDRAM start-up code.

Shortly before Shenzhen-based Vamrs Limited launched a Rockchip RK3399 Sapphire SBC in Nov. 2017, the company announced a similarly open-spec Rock960 SBC that uses the same Rockchip RK3399 SoC, but instead adopts the smaller, 85 x 55mm 96Boards CE form factor. The Rock960 was showcased in March along with other AI-enabled boards as part of Linaro’s 96Boards.ai initiative announcement.

Software and Games: Hegemon, Gift of Parthax, Lutris

  • Hegemon – A Modular System Monitor Application Written In Rust
    When it comes to monitor running processes in Unix-like systems, the most commonly used applications are top and htop, which is an enhanced version of top. My personal favorite is htop. However, the developers are releasing few alternatives to these applications every now and then. One such alternative to top and htop utilities is Hegemon. It is a modular system monitor application written using Rust programming language.

    Announced yesterday after a pretty short beta period, the magical arena fighting game Gift of Parthax is now officially available for Linux. Along with putting the Linux build out in public, their latest release also fixes a few bugs. The developer sent over a key and I've been testing it, the Linux version seems to be working really quite nicely. If you liked the idea of Wizard of Legend, but found it a little too fast for your tastes then Gift of Parthax might be a better fit although it's single-player only.

    I have to admit, the game manager Lutris [Official Site] has come along quite a bit since I last used it. Today, version 0.4.20 was made available. For those not aware of it, Lutris is an application that aims to give you a single place to manage all your games on Linux. It supports native games, Wine, various emulators and so on. The application itself is available under the GPL and the helper scripts to install games can be viewed before using them so it's quite nice.

  • Editor's Corner—Open source is not 'one size fits all' [Ed: But that's a plus, not a minus. With proprietary software it's one unsuitable thing for everything; doesn't scale.]
    Open source communities are no doubt playing a key role in moving the telecommunications industry forward, but not everyone is on board the bandwagon. Over the past five months or so, we've spent a fair amount of time writing about open source groups and standards development organizations (SDOs) such as the Linux Foundation, MEF, Open Networking Foundation, OpenDaylight, the TM Forum and ETSI, and there's clearly more cooperation afoot for the good of the industry. But artificial intelligence startup B.Yond's chief marketing officer, Rikard Kjellberg, said his company has to be careful when it comes to choosing which open source community to commit its resources to. Kjellberg spoke to FierceTelecom on the heels of the AT&T Spark conference earlier this month.

At this week’s Open Networking Summit Europe in Amsterdam, delegates heard that DevOps, automation, cloud, big data and analytics, software-defined networking (SDN), and management and orchestration (MANO) were increasingly being supported by open source solutions. Commissioned research questioned 150 CSP representatives across 98 companies worldwide. It found that 98% of CSPs are “confident” that open networking solutions can achieve the same level of performance as traditional networking solutions.
