QEMU 5.0 Supports Recent Armv8.x Features, Cortex-M7 CPU, Host Directory Access, and More

Qemu 5.0

QEMU (Quick EMUlator) is an open-source emulator that’s great to run programs on various architectures such as Arm, RISC-V, and many others when you don’t own proper hardware. The developers have now released QEMU 5.0.0 will plenty of new features and such as support for Armv8.1 to Armv8.4 architectures, Arm Cortex-M7 processor, various changes to MIPS, PowerPC, RISC-V, s390… architectures, support for accessing a directory on the host filesystem from the guest using virtiofsd and more. There have been over 2800+ commits from 232 developers, so the list of changes to too long to write here, but some of the highlights include: Support for passing host filesystem directory to guest via virtiofsd Support for ARMv8.1 VHE/VMID16/PAN/PMU, ARMv8.2 UAO/DCPoP/ATS1E1/TTCNP, ARMv8.3 RCPC/CCIDX,  ARMv8.4 PMU/RCPC Added ARM Cortex-M7 CPU support New Arm boards: tacoma-bmc, Netduino Plus 2, and Orange Pi PC Allwinner SoC model now wires up the USB ports TPM support for […]

Ampere eMAG 64bit Arm Workstation Enables Native Arm Development

Ampere eMAG 64bit Arm Workstation

Over the last few years, several companies have come up with 64-bit Arm workstation to allow developers to test Arm code natively which may be important to avoid network delays or test applications requiring video or graphics. Those started to become available in 2018 from the relatively low-end  24-core Cortex-A53 Linaro “Synquacer” Developerbox to the much more powerful (and expensive) GIGABYTE ThunderXStation Workstation powered by up to two 32-core ThunderX2 processors. In the fall of 2019, SolidRun started to ship HoneyComb LX2K 16-core Arm Workstation motherboard with and NXP LX2160A 16-core Cortex-A72 processor that offers significantly more performance than the Linaro Box at a reasonable price ($750). While reading a recent Anandtech post with photos of an engineering sample, I found out Avantek was also offering the Ampere eMAG 64bit Arm Workstation powered by an Ampere eMAG 8180 32-core server processor. Ampere eMAG 64-bit Arm workstation specifications: SoC – Ampere […]

This is what HoneyComb LX2K 16-core Arm Workstation Looks Like (Video)

Arm Workstation

Back in February 2019, while referring to Arm server, Linus Torvalds famously said: I can pretty much guarantee that as long as everybody does cross-development, the platform won’t be all that stable. Or successful. … If you develop on x86, then you’re going to want to deploy on x86, because you’ll be able to run what you test “at home” (and by “at home” I don’t mean literally in your home, but in your work environment). … Which in turn means that cloud providers will end up making more money from their x86 side, which means that they’ll prioritize it, and any ARM offerings will be secondary and probably relegated to the mindless dregs (maybe front-end, maybe just static html, that kind of stuff). SolidRun had already worked on products with NXP LX2160A 16-core Arm Cortex A72 processor and found out it could be a match to make a powerful […]

Ampere Altra Announces 80-Core Arm Neoverse N1 Server Processor & Reference Designs

Ampere Altra

The first 64-bit Arm server processor was announced almost 9 years ago. Applied Micro X-Gene was found in several servers, and the company updated X-Gene family until it got bought by Ampere in 2018. The latter has now announced the first of their own design with Ampere Altra, an 80-core Arm Neoverse N1 server processor made for data centers. Ampere Altra specifications: Processor Subsystem 80x Arm v8.2+ 64-bit CPU cores up to 3.0 GHz with Sustained Turbo 64 KB L1 I-cache, 64 KB L1 D-cache per core, 1 MB L2 cache per core, 32 MB System Level Cache (SLC) 2x full-width (128b) SIMD Coherent mesh-based interconnect, distributed snoop filtering System memory 8x 72-bit DDR4-3200 channels ECC, Symbol-based ECC, and DDR4 RAS features Up to 16 DIMMs and 4 TB/socket System Resources Full interrupt virtualization (GICv3) Full I/O virtualization (SMMUv3) Enterprise server-class RAS Connectivity 128 lanes of PCIe Gen4 8 x8 […]

Arm Micro-ATX Desktop PC Motherboard

There have been attempts to bring Arm processors to desktop PC’s in recent years with projects such as 96Boards Synquacer based on SocioNext SC2A11 24-core Cortex-A53 server processor or Clearfog-ITX workstation equipped with the more powerful NXP LX2160A 16-core Arm Cortex A72 networkingprocessor @ 2.2 GHz. Those solutions were also based server and networking SoCs, but there may soon be another option specifically designed for Arm Desktop PCs as a photo of an Arm Micro-ATX motherboard just showed up on Twitter. Here are the specifications we derive from the Tweet and the photo: SoC – Phytium FT2000/4 quad core custom Armv8 (FTC663) desktop processor @ 2.6 – 3.0 GHz with 4MB L2 Cache (2MB per two cores) and 4MB L3 Cache; 16nm process; 10W power consumption; 1144-pin FCBGA package (35×35 mm) System Memory – 2x SO-DIMM slot supporting 72-bit (ECC) DDR4-3200  memory Storage – 4x SATA 3.0 connectors; MicroSD card […]

Arm Cortex-A34 is a 64-bit Only Low-Power Core

Arm Cortex-A34

Arm previously announced Cortex-A35 64-bit & 32-bit lower-power CPU core, and later on Cortex-A32 32-bit only Armv8 CPU core with the usual press release, and blog posts providing details about their new offering. But this morning, I saw a tweet about Cortex-A34… https://twitter.com/never_released/status/1157107187375886337 Based on the twitter handle, I first assumed it was “never released” ;), and was just an internal part name at Arm. But the new Cortex-A34 was actually very discreetly outed last month when Arm announced Flexible Access to lower the barrier of entry by allowing IC designers to access all Arm IP in the program, and only pay for IP blocks they actually use in the final product. Nevertheless, the product page and developer documentation are now up – albeit with limited info for the latter -, so we have more details. Some of the highlights of Arm Cortex-A34 core include: Architecture – 64-Bit Armv8-A Multicore […]

Texas Instruments To Finally Launch a 64-bit Processor with AM654 SoC

Sitara AM652 Block Diagram

Texas Instruments has a wide portfolio of Arm-based processors targeting industrial control with their Sitara family. So all their models, including the latest Sitara AM57x family, were based on 32-bit Arm cores. But a somewhat recent Linux mainline kernel commit reveals the company has been working on a 64-bit Arm processor family, namely AM65x family, and one the first processor will be TI AM654 “Keystone III” quad-core Arm Cortex-A53 + dual lockstep Cortex-R5F processor. The AM654 SoC is said to be a lead device of the K3 multicore SoC architecture targeting both the broad market and industrial control. Some of the key features and specifications include: CPU – Quad ARMv8 A53 cores split over two clusters GPU – PowerVR SGX544 GICv3 compliant GIC500 Configurable L3 Cache and IO-coherent architecture Dual lock-step capable R5F uC for safety-critical applications High data throughput capable distributed DMA architecture under NAVSS 3x Gigabit Industrial Communication […]
