V-Raptor Edge RK3399 Mini PC Runs Xubuntu 18.04 with EBBR Support

We previously wrote about XS LAB’s V-Raptor server equipped with SocioNext SC2A11 24-core Arm Cortex-A53 SoC, but the Korean company has been working on a different kind of project with V-Raptor Edge mini PC powered by Rockchip RK3399 processor and running Xubuntu 18.04 with an Arm EBBR-compliant UEFI bootloader. The mini PC was designed to work as a thin client for Cloud PC VDI service from SK Broadband, but XS Lab appears open to expand its use to other applications depending on interest from distributors. V-Raptor Edge PC preliminary specifications: SoC – Rockchip RK3399 hexa-core processor with 2x Arm Cortex-A72 cores @ up to 1.8 GHz, 4x Arm Cortex-A53 cores System Memory – 4GB LPDDR4 Storage – 16GB eMMC flash or 32GB MicroSD card Video Output – HDMI 2.0 up to 4K, and DisplayPort via USB-C port; dual-independent display support up to 2x Full HD Audio – 3.5mm headphone jack, […]

Panfrost Open-Source Arm Mali GPU Driver Gets Experimental OpenGL ES 3.0 Support

Panfrost is the open-source driver being developed for Arm Midgard and Bitfrost GPUs. The first versions focused on support for OpenGL ES 2.0, but the more recent OpenGL ES 3.0 enables faster and more realistic rendering. The goods news is that Panfrost support for experimental OpenGL ES 3.0 has landed in Mesa according to a recent post on Collabora blog. Specifically, Panfrost now supports instanced rendering, primitive restart, uniform buffer objects, 3D textures, and multiple render targets (on Mali T760 and up) all of which are OpenGL ES 3.0 features. People who are not into graphics development may not know about the purpose of those features, but Alyssa Rosenzweig, a free software graphics hacker leading Panfrost, explains: … instanced rendering and primitive restart allow developers to write faster graphics applications, to render efficiently scenes more complex than possible in ES 2.0. … uniform buffer objects and 3D texture give developers […]

NetBSD 9.0 Released with Aarch64 Support, Arm ServerReady Compatibility

Yesterday, we wrote about Raspberry Pi 4 getting UEFI+ACPI firmware for Arm SSBR compliance allowing the board to run operating systems designed for “Arm ServerReady” servers out of the box. NetBSD 9.0 was just released on February 14, 2020, with support for Aarch64 (64-bit Arm) which had been in the works for a few years, and includes support for “Arm ServerReady” compliant machines (SBBR+SBSA). NetBSD 9.0 main changes related to hardware support: Support for AArch64 (64-bit Armv8-A) machines Compatibility with “Arm ServerReady” compliant machines (SBBR+SBSA) using ACPI. Tested on Amazon Graviton and Graviton2 (including bare metal instances), AMD Opteron A1100, Ampere eMAG 8180, Cavium ThunderX, Marvell ARMADA 8040, QEMU w/ Tianocore EDK2 Symmetric and asymmetrical multiprocessing support (big.LITTLE) Support for running 32-bit binaries via COMPAT_NETBSD32 on CPUs that support it Single GENERIC64 kernel supports ACPI and device tree based booting Supported SoCs Allwinner A64, H5, H6 Amlogic S905, S805X, S905D, […]

Antmicro GEM ASIC Leverages zGlue Technology to Quickly Bring Custom Arm/RISC-V SoC’s to Market

Introduced in 2018, ZiP (zGlue Integration Platform) chip-stacking technology aims to produce chips similar to Systems-in-Package (SiP) but at much lower costs and lead times. We first found it in a Bluetooth tracker featuring ZGLZ1BA custom chip manufactured with zGlue technology and integrating an Arm Cortex-M0 MCU, flash memory and sensors into a single package. But now the technology is back in the news with Antmicro announcing GEM chiplet-based ASIC last December. At the time of the announced the company’s GEM1 chip featured two Lattice iCE40 FPGAs with a MIPI CSI-2 switch, and they had started working on GEM2 chip combining a hard RISC-V processor and Lattice iCE40 FPGA. Those are so-called demonstrators chip as Antmicro customers will be able to easily and quickly design their own 6×9 mm chip(s) with RISC-V and/or ARM CPUs, FPGAs, sensors, radios and other functional elements to meet the requirements of their specific applications.

Arm Introduces Cortex-M55 MCU Core, Arm Ethos-U55 microNPU for Cortex-M Microcontrollers

Artificial Intelligence and the Internet of Things often go hand in hand with AIoT being a new buzz word that came up last year or so. But for AIoT to scale we need ultra-low-cost, low-power solutions capable of doing inference at the sensor node level, and this is only possible with microcontrollers. To achieve this goal, Arm has just unveiled the Arm Cortex-M55 microcontroller core optimized for artificial intelligence workloads that delivers up to a 15x uplift in ML performance and a 5x uplift in DSP performance with greater efficiency, as well as Ethos-U55 microNPU designed for Cortex-M microcontrollers that need even more AI performance (up to 480 times faster), while consuming as little power as possible. Arm Cortex-M55 Key features and specifications: Architecture – Armv8.1-M Bus interface – AMBA 5 AXI5 64-bit master (compatible to AXI4 IPs) Pipeline – 4-stage (for main integer pipeline) Security – Arm TrustZone technology […]

Linux 5.5 Release – Main Changes, Arm, MIPS and RISC-V Architectures

Linux 5.5 has just been released by Linus Torvalds: So this last week was pretty quiet, and while we had a late network update with some (mainly iwl wireless) network driver and netfilter module loading fixes, David didn’t think that warranted another -rc. And outside of that, it’s really been very quiet indeed – there’s a panfrost driver update too, but again it didn’t really seem to make sense to delay the final release by another week. Outside of those, it’s all really tiny, even if some of those tiny changes touched some core files. So despite the slight worry that the holidays might have affected the schedule, 5.5 ended up with the regular rc cadence and is out now. That means that the merge window for 5.6 will open tomorrow, and I already have a couple of pull requests pending. The timing for this next merge window isn’t optimal […]

JP.IK Turn T101 Qualcomm Snapdragon 7c Laptop for Education to Sell for $299 and Up

Qualcomm Snapdragon Windows 10 mobile PCs/laptops offer long battery life and 4G LTE connectivity, but usually suffer from a disappointing performance/price ratio. That means you may have to spend fairly more than you may expect for a Windows 10 Arm laptop, and for instance, Microsoft Surface Pro X goes for $999 and up with a Snapdragon 8cx based Microsoft SQ1 processor. But much more affordable Arm laptop may not be that far off, as Microsoft published some news about their education solutions, and two new Snapdragon 7c laptops are in the works: JP.IK Turn T101 starting at $299 Positivo Wise N1212S starting at $575 Both laptops promise twice the battery life and 25 percent better performance than competing platforms, as well as (4G LTE) cellular connectivity. A $300 Arm laptop with decent performance looks promising, but so far we have very few details at this point, so I’ll speculate […]
