At Mobile World Congress, Sprint and Cavium worked together to show a network function virtualization (NFV) demo on Cavium ThunderX2 hardware running in Packet’s public cloud.
The containerized mobile core network (cEPC) runs at Packet, a commercially available public cloud, on Cavium ThunderX2 Arm-based servers. The radio access network is a 3GPP compliant split-RAN implementation with both the vBBU (virtualized baseband unit) and the remote radio unit running on Cavium silicon (ThunderX2 and OCTEON Fusion-M® processors).
Gema Gomez of Linaro writes about bringing up the Queens release of OpenStack on arm64. OpenStack provides a system execution environment based on virtual machines, with governance for the project organized by the OpenStack Foundation.
Queens is the first release that we feel confident will run out of the box on ARM64, a milestone of collaboration not only from the Linaro member companies but also from the OpenStack community at large. OpenStack projects have been welcoming of the diversity and inclusive, helping us ramp up: either giving direction and reviewing our code or fixing issues themselves.
Jim put together a design to share for a 3d-printed case with a power supply and a readout for system voltage on the front.
A case for the Rock64 and a 2.5″ drive. The drive sits in the bottom section, the Rock64 goes on the mounting plate and the lid has mounts for a pair of buck converters and a fan. Normal use is probably to skip the buck converters and use the standard power supply, but I have a tendency to over-engineer things.
Maxime Ripard from Bootlin (formerly Free Electrons) has successfully funded a Kickstarter campaign for upstream support for video drivers for the Allwinner VPU. The goal is to reverse engineer this system and put drivers into the mainline Linux kernel.
As a result of this funding, Paul Kocialkowski has been hired on as an intern to work on this code. The Kickstarter campaign continues with stretch goals to add additional codecs and support more platforms.
Qiang Yu (yuq) is working on open source drivers for the ARM Mali 400/450 GPUs to support OpenGL. The typical vendor distribution for Mali support uses closed-source binary blobs. This effort looks to reverse-engineer the core functions of this processor, and comes with a whole set of warnings about how various functions may be subject to licenses.
Since the announcement of MariaDB on arm64 for the Qualcomm platform in November, developers have been working on performance tuning for that platform to optimize write operations.
Sandeep Sethia from Qualcomm discussed the port and optimization at the MariaDB Developers Unconference, February 24-25, 2018 in New York City, with slides available.
We are pleased to announce a number of performance improvements that are being made available in the recently shipped 10.3 release candidate 10.3.4. By leveraging the highly parallelized 48-core Qualcomm Centriq 2400 processor running at 2.6GHz with 6 memory channels in a fully coherent ring architecture, our interest is to extract write performance optimization in a single row write use case for a highly threaded application.
HP is taking pre-orders for the Envy X2 laptop, one of the first Windows devices powered by Qualcomm’s Snapdragon 835 arm64 processor.
HP’s first Windows 10 PC that’s powered by an ARM-based processor is now available for preorder for $999.99. It’s scheduled to ship by March 9th, and it’s one of the first “always connected PCs” that HP, Asus, and Lenovo have teamed up with Qualcomm to release over the next year or so.
