In this issue Cadence support on ThunderX2 UEFI on Qualcomm…
Arm: “Project Trillium represents a suite of Arm products that gives device-makers all the hardware and software choices they need. It also enables a seamless link into a bank of Arm partners delivering neural network (NN) apps including leading frameworks such as Google TensorFlow, Caffe, Android NN API and MXNet.”
EE Times, Tirias Research: “Arm claims its cores will sport 3 TOPs/Watt, more than 4.6 TOPs in total (8-bit integer) performance and up to a 4x increases in performance with further optimizations. Initially, Project Trillium cores have a target power consumption of 1.5W on a 7nm fabrication process. The new cores can be integrated with existing Arm cores in a unified memory architecture that leverages open source software.”
Packet has published a case study of Resin.IO moving from QEMU emulation to native builds on Arm hardware, with a speedup of up to 5x.
The other big plan for this year is to launch their own Arm-based hardware: a carrier board based on the Raspberry Pi compute module 3 that was released last year. “We’re building in a lot of features that our customers find missing from stock Raspberry Pi’s when they scale up from prototype to production,” says Alison Davis, the company’s director of product marketing and strategy. The carrier board will have onboard storage and industrial connectors and power.
/proc/cpuinfo file in on a Linux system shows details of the CPU you are running on. On Arm systems it has rather less detail than on other legacy processors. Riku Voipio of Linaro writes about the difficulties in getting the wide range of details around new Arm processors into the Linux kernel, and solves the problem of identifying your Arm system with enhancements to
Similar projects for identifying processor capabilities are
hwloc from the OpenMPI community, and Google’s C++ library
It’s “slow as dirt”, but engineer Rafael Rivera has the new arm64 Windows 10 booting on a legacy processor with QEMU. It involves running hand-crafted UEFI firmware and recompiled/signed arm64 storage drivers, and it includes a whimsical boot logo to discourage serious usage.
Richard Gee walks the reader through building Docker multi-arch images, using the new
docker manifest tool available in Docker 18.02-ce and later.
Why? Quite simply, it removes complexity. In the pre-multi-arch world it would typically be the case that multiple Docker hub repo’s would need to be visited, namespaces determined, or tags forensically interrogated in order to create bespoke Dockerfiles for each platform being targeted by the application.
CNCF created the Serverless Working Group to “explore the intersection of cloud native and serverless technology.” The first output of the group was creation of serverless landscape, which is available here. The whitepaper is the second contribution of the Serverless Working Group. The whitepaper goes beyond merely answering the questions facing the serverless community; it defines serverless computing:
Serverless computing refers to the concept of building and running applications that do not require server management. It describes a finer-grained deployment model where applications, bundled as one or more functions, are uploaded to a platform and then executed, scaled, and billed in response to the exact demand needed at the moment.
“Not a review yet” but lots of pictures.
What we already know is that the SoC is one of Rockchip’s ‘open source SoCs’ so software support is already pretty good and the chip vendor itself actively upstreams software support. We also know RK3399 is not the greatest choice for compiling code… We also know that this SoC has 2 USB3 ports and implements PCIe 2.1 with a four lane interface. But so far we don’t know how the internal bottlenecks look like so let’s focus on this now.
Peter Robinson from Fedora is guest on the Fedora Council subproject meeting, available in recorded form via Youtube, discussing running Fedora on “Internet of Things” devices. It’s a thoughtful account of what it takes to bring an existing operating system to an ecosystem.
