  • SoM/baseboard combo forms ST Cortex A7/M4 hybrid-based SBC

    SeeedStudio has developed the Odyssey-STM32MP157C, an SBC comprised of an SoM based on ST’s STM32MP1 SoC and the Raspberry Pi-like NPI-STM32MP157C baseboard.

    SeeedStudio has built an SoM based on STMicroelectronics’ Arm Cortex A7/M4 hybrid SoC called the SOM-STM32MP157C, along with a Raspberry Pi “inspired” baseboard called the NPi-STM32MP157C. Together these products form a new SBC designated Odyssey-STM32MP157C. Although product details for the SBC yet to appear for on Seeed’s website at the time of this writing, specs and documentation are available on Seeed’s GitHub pages as well as distributor sites Digi-Key and Mouser. The SBC is targeted for applications such as consumer,industrial, white goods, medical and wearable devices.

  • Apollo Lake in-vehicle PCs have four PoE ports

    Nexcom’s “nROK 6222” and similar “VTC 6222” are rugged, Linux-ready in-vehicle computers with an Intel Apollo Lake SoC, 5x GbE (4x with PoE), 3x mini-PCIe, 2x SATA, 2x HDMI, and CAN, serial, VGA, USB 3.0, and GPS.

    Nexcom announced a nROK 6222 computer for rolling stock applications and a similar VTC 6222 system for more general-purpose in-vehicle usage. Both systems run Linux or Win 10 on an up to 2GHz, quad-core Atom E3950 from Intel’s Apollo Lake generation. They’re both designed to connect with IP surveillance cameras via 4x Power-over-Ethernet (802.3af/at) enabled GbE ports. They can also assist centralized fleet management applications with extensive wireless support.

  • The Future of Embedded Software

    As the world continues its steady march towards ubiquitous computing, almost everything from airplanes to toasters is being powered by embedded software. In fact, technology is so pervasive, we take connected homes, advanced medical equipment, and self-driving cars almost for granted.

    However, many of us who work in the industry have some misgivings about what this explosion in embedded software ultimately means. There are some very important issues that need to be openly discussed and solved before it’s too late.

    For instance, why are there no standards to ensure embedded products are designed with quality in mind? A washing machine breaking down due to poorly designed code is one thing, but what about a car? In an industry with no professional certification, who’s responsible for software-related tragedies? It’s easy to think that companies are sparing no expense to build and maintain critical software to the utmost degree of excellence – when we all know that the opposite may be closer to the truth.

GNU/Linux in Crostini Form

  • Using 'LXPanel' as a UI for Crostini

    If you are used to a menu-driven user interface in Linux or find the Chrome OS application launcher not quite to your liking for accessing Crostini Linux applications then one option you could try is LXPanel. The panel generates a menu for installed applications automatically from '*.desktop' files and can itself be incorporated in its own '.desktop' file which if pinned to the Chrome OS shelf can also be used as a means to start the 'penguin' container after booting. Unfortunately it is not quite perfect as the panel is displayed in the middle of the screen and doesn't respond well to changing its position under geometry in its panel settings. However you can toggle its visibility by clicking the panel's icon on the shelf. Also closing the panel (by right clicking the icon) only closes the 'LXPanel' application in Chrome OS so to terminate it fully you need to use 'killall lxpanel' in a terminal session.

  • Linux apps on Chromebooks may be reason enough for external GPU support

    We’ve been tracking a device known only as ‘Mushu’ for about a month at this point, and it brings with it a very specific and interesting addition to the Chrome OS ecosystem: a discrete GPU (or dGPU for short). When we first reported on this device being in development, I suggested that I don’t see a ton of use cases for a Chromebook with a dGPU for most users. Without a proper video editor or tons of ways to play locally-stored games, its hard to make a case for dGPUs when existing Chromebooks are already so fast at what they do.

NVIDIA's Ray Tracing Approach in Vulkan

  • NVIDIA talk up bringing DirectX Ray Tracing to Vulkan

    With Ray Tracing becoming ever more popular, NVIDIA have written up a technical post on bringing DirectX Ray Tracing to Vulkan to encourage more developers to do it. The blog post, titled "Bringing HLSL Ray Tracing to Vulkan" mentions that porting content requires both the API calls (so DirectX to Vulkan) and the Shaders (HLSL to SPIR-V). Something that's not so difficult now, with the SPIR-V backend to Microsoft's open source DirectXCompiler (DXC). Since last year, NVIDIA added ray tracing support to DXC's SPIR-V back-end too using their SPV_NV_ray_tracing extension and there's already titles shipping with it like Quake II RTX and Wolfenstein: Youngblood. While this is all NVIDIA-only for now, The Khronos Group is having discussions to get a cross-vendor version of the Vulkan ray tracing extension implemented and NVIDIA expect the work already done can be used with it which does sound good.

  • NVIDIA Demonstrates Porting Of DirectX Ray-Tracing To Vulkan

    NVIDIA has written a new technical blog post on bringing HLSL ray-tracing to Vulkan with the same capabilities of DirextX Ray-Tracing. This effort is made feasible by Microsoft's existing open-source DirectXCompiler (DXC) with SPIR-V back-end for consumption by Vulkan drivers. Last year NVIDIA contributed to the open-source DXC support for SPV_NV_ray_tracing. This in turn with the open-source tooling allows converting DXR HLSL shaders into SPIR-V modules for Vulkan.

Vulkan Survey and AMDVLK, AMD Targets GNU/Linux

  • LunarG's Vulkan developer survey results out now - Vulkan also turns 4

    LunarG, the software company that Valve sponsors who work on building out the ecosystem for the Vulkan API recently conducted a Vulkan developer survey with the results out now. Before going over the results, just a reminder that Vulkan just recently turned four years old! The 1.0 specification went public on February 16, 2016. Since then, we've seen some pretty amazing things thanks to it. We've had Linux ports that perform really nicely, the mighty DXVK translation layer advanced dramatically, to the vkBasalt post-processing layer and so on—there's been a lot going on. However, as a graphics API do remember it's pretty young and has a long life ahead of it. As for the LunarG survey: there were 349 replies to it, and while not a huge amount it gives us an interesting insight into what some developers think and feel about how Vulkan is doing as a whole. Overall, it gives quite a positive picture on the health of Vulkan with over 60% feeling the overall quality of the Vulkan ecosystem as "Good" and almost 20% rating it as "Excellent".

  • AMDVLK 2020.Q1.2 Released With Vulkan 1.2 Support

    AMDVLK 2020.Q1.2 is out as the first official AMD open-source Vulkan Linux driver code drop in one month. AMDVLK has been off its wagon this quarter with their previous weekly/bi-weekly code drops of AMDVLK but that just means the v2020.Q1.2 is quite a big one. First up, AMDVLK 2020.Q1.2 now is supporting Vulkan 1.2 that debuted back in January and with Mesa's RADV Radeon Vulkan driver already having supported it for weeks.
