It Turns Out RISC-V Hardware So Far Isn't Entirely Open-Source

Filed under
Hardware

While they are trying to make it an open board, as it stands now Minnich just compares this RISC-V board as being no more open than an average ARM SoC and not as open as IBM POWER.

Ron further commented that he is hoping for other RISC-V implementations from different vendors be more open.

  • Congatec teams up with OSADL for real-time Linux

    In a first step, OSADL qualified congatec’s latest real-time Linux implementation that uses Linux kernel 4.9.47-rt37 on conga-TS170 Server-on-Modules equipped with the embedded server-class Intel Xeon processor (E3-1578L v5 at 2.00GHz). The challenge when implementing hard real-time Linux behaviour lies in mastering all processing layers from BIOS to Linux kernel to user space, since the overall real-time capabilities are only as good as the weakest link in the chain. In addition, modern processors such as Intel’s Skylake family offer a wide range of energy saving features that must be balanced to the requirements of real-time computing. Executed in standardized racks, the OSADL quality assurance testifies that conga-TS170 Server-on-Modules are perfect for any real-time application. The boards support all major real-time capable OS from both x86 and ARM technologies. These include first and foremost real-time Linux but also further RTOS such as VxWorks or QNX, as well as deterministic hypervisor and virtualization technologies from vendors such as Real-Time Systems.

Once in the field, the Intel® NUC is built to ensure deployment is easily manageable and runs seamlessly with little operational support needed.

  • Intel CEO Brian Krzanich quits biz after fling with coworker rumbled

    Intel chief exec Brian Krzanich has quit after his “past consensual relationship” with an employee came to light.

    Staff flings are frowned upon in US corporate tech world, and against Intel company policy, which bans bosses from having relationships with people who report to them, directly or indirectly.

  • Intel CEO Brian Krzanich Resigns

    While Intel's second quarter revenue and non-GAAP EPS is exceeding their prior guidance, Intel CEO Brian Krzanich has resigned effective immediately.

  • Intel Hyper Threading Performance With A Core i7 On Ubuntu 18.04 LTS

    Following the news yesterday of OpenBSD disabling Intel Hyper Threading by default within its OS over security concerns and plans to disable Simultaneous Multi Threading for other processors/architectures too, here are some fresh Intel HT benchmarks albeit on Ubuntu Linux. The OpenBSD developer involved characterized HT/SMT as "doesn't necessarily have a positive effect on performance; it highly depends on the workload. In all likelihood it will actually slow down most workloads if you have a CPU with more than two cores." So here are some benchmarks using a current-generation Intel Core i7 8700K six-core processor with Hyper Threading.

  • SMT Disabled by Default in -current
  • OpenBSD Will Disable Intel Hyper-Threading To Avoid Spectre-Like Exploits

    OpenBSD, an open source operating system that focuses on security, announced that it will disable Intel’s Hyper-Threading (HT) feature so that attackers can no longer employ Spectre-like cache timing attacks.

  • Intel’s hyperthreading blocked on OpenBSD amid hints of new Spectre-like bugs

    The maintainer of open source Unix-like operating system, OpenBSD, has announced that it will disable hyperthreading on Intel CPUs because of security concerns. It claims that simultaneous multithreading creates a potential new attack vector for Spectre-like exploits, and plans to expand its disabling of multithreading technologies to other chip manufacturers in the near future.

Chip makers are starting to catch on to the advantages of open, however. SiFive has released an entirely open RISC-V development board. Its campaign on the Crowd Supply crowd-funding website very quickly raised more than $140,000 USD. The board itself is hailed as a game-changer in the world of hardware. Developments like these will ensure that it won't be long before the hardware equivalent of LEGO's bricks will soon be as open as the designs built using them.

Ubuntu

Kontron’s rugged “EvoTrac G102” is an in-vehicle cellular gateway that runs Ubuntu on a quad-core Atom E3845, and offers 64GB eMMC, GbE, CAN, 2x USB, and a 3G/4G module with GPS.

Kontron unveiled the EvoTrac G102 last month, and earlier this month announced that it will act as the control box for Hyliion’s 6X4HE “intelligent electric hybrid system for Class 8 trucks and trailers.” The 6X4HE provides regenerative braking design to capture power for fuel savings of up to 30 percent,” says Kontron.

DFI’s “KS-156AL” industrial touch-panel PC runs Linux or Windows on Apollo Lake and features a 15.6-inch, 1366 x 768 touchscreen with IP65 protection and shock and vibration resistance.

DFI’s Linux-friendly, 15.6-inch KS-156AL panel PC is based on its AL171 mini-ITX board, which was announced a year ago along with the similar AL173 which is otherwise identical except for the addition of wide-range power. The KS-156AL was recently announced along with a similarly Intel Apollo Lake based, 7-inch KS070-AL panel PC. The 7-inch KS070-AL is supported only with Windows, although it’s based on a 3.5-inch, “coming soon” AL551 SBC that also supports Ubuntu. The two systems are designed for factory automation, transportation, and other embedded applications.

  • Intel Begins Queuing Graphics Driver Improvements For Linux 4.19

    While the Linux 4.18 kernel merge window isn't even over until the end of the week followed by about eight weeks worth of testing before that kernel version will debut as stable, Intel open-source developers have already sent in their first pull request to DRM-Next of material they would like to begin staging for Linux 4.19.

    Intel's OTC developers are usually quite punctual in queuing up their tested work in DRM-Next for the next kernel cycle while even for their standards this is quite early with there being several days left to the current merge window.

  • Linux Kernel Patches Appear For A Line Of Intel MIPS SoCs

    It appears Intel is launching a line of SoCs based on the MIPS architecture.

    Hitting the kernel mailing list overnight is a set of kernel patches for bringing up the Intel GRX500 SoCs, which are based on the MIPS interAptiv design. MIPS interAptiv processor cores are based on a 32-bit, multi-core design and have been available the past few years. Background information on interAptiv is available from MIPS.com.
