Libre-SOC's NLnet-funded entirely Libre 180nm ASIC, which can be replicated down to symbolic level GDS-II with no NDAs of any kind, has been submitted to IMEC for fabrication. It is the first wholly-independent Power ISA ASIC outside of IBM to go Silicon in 12 years. Microwatt went to Skywater 130nm in March however it is also developed by IBM, as an exceptionally well-made Reference Design, which Libre-SOC used for verification.
Whilst it would seem that Libre-SOC is jumping on the chip shortage innovation bandwagon, it has actually been in development for over 3 and a half years so far: it even pre-dates the OpenLane initiative, and has the same objectives: full automated HDL to GDS-II, full transparency and auditability with Libre VLSI tools Coriolis2 and Libre Cell Libraries from Chips4Makers.
With EUR 400,000 in funding from NLnet and an application to NGI Pointer under consideration, the next steps are to continue development of Draft Cray-style Vectors (SVP64) to the already Supercomputer-level Power ISA, under the watchful eye of the upcoming OpenPOWER ISA Workgroup.

Over the past several weeks, NASA satellite measurements have revealed significant reductions in air pollution over the major metropolitan areas of the Northeast United States. Similar reductions have been observed in other regions of the world. The data indicate that the nitrogen dioxide levels in March 2020 are about 30% lower on average across the region of the I-95 corridor from Washington, DC to Boston than when compared to the March mean of 2015-19

Michael Larabel, of Phoronix, writes that the OpenPower Foundation has released a license agreement for Hardware Vendors to implement the Power ISA RISC instruction set in their processors. Hugh Blemings, the Director of OpenPower, was responsible for ensuring that the EULA is "favourable anf friendly" towards Libre and Open Hardware projects and businesses.
Of particular interest is that IBM's massive patent portfolio is automatically granted, royalty-free as long as two conditions apply: firstly, the hardware must be fully and properly Power ISA compliant, and secondly, the implementor must not "try it on" as a patent troll.
Innovation in the RISC space just got a little more interesting.

The Libre RISC-V Hybrid CPU/GPU, previously reported on /., is applying for eight additional grants from the NLNet Foundation, totalling EUR 400,000. Details on each Grant Application are on the newly-opened RISC-V Community Forum.
The general idea is to kick RISC-V into a commercially-viable mass-volume high gear by putting forward funding proposals for NEON/SSE-style Video Acceleration to be upstreamed for use by ffmpeg, vlc, mplayer and gstreamer; hardware-assisted Mesa 3D (a port of the RADV Vulkan Driver to RISC-V), and a hardware-accelerated OpenCL port to RISC-V. This all in a "Hybrid" fashion (a la NEON/SSE) as opposed to the "usual" way that 3D and Video is done, which hugely complicate both software drivers and applications debugging.
In addition, the Libre RISC-V SoC itself is applying for grants to do a gcc port supporting its Vectorisation Engine including auto-vectorisation, and, crucially, to do an entirely Libre-licensed ASIC Layout using LIP6.fr coriolis2, working in tandem with Chips4Makers to create a 180nm commercially-viable single-core dual-issue test ASIC.
The process takes approximately 2-3 months for approval. Once accepted, anyone may be the direct (tax-deductible) recipient of NLNet donations, for sub-tasks completed. Worth noting: Puri.sm is sponsoring the project, and, given NLNet's Charitable Status, donations from Corporations (or individuals) are 100% tax-deductible.

The NLNet Foundation has approved funding for the Hybrid Libre RISC-V CPU/VPU/GPU under its Privacy and Enhanced Trust Programme. High security software is irrelevant if the hardware is fundamentally compromised, for example with the Intel spying backdoor co-processor known as the Management Engine. The Libre RISCV SoC was begun as a way for users to regain trust and ownership of the hardware that they legitimately purchase.
This processor will be the first of its kind, as the first commercial SoC designed to give users the hardware and software source code of the 3D GPU, Video Decoder, main processor, boot process and the OS.
Shockingly, in the year 2019, whilst there are dozens of SoCs with full source code that are missing either a VPU or a GPU (such as the TI OMAP Series and Xilinx ZYNQ7000s), there does not exist a single commercial embedded SoC which has full source code for the bootloader, CPU, VPU and GPU. The iMX6 for example has etnaviv support for its GPU however the VPU is proprietary, and all of Rockchip and Allwinner's offerings use either MALI or PowerVR yet their VPUs have full source (reverse engineered in the case of Allwinner).
This processor, which will be quad core dual issue 800mhz RV64GC and capable of running full GNU/Linux SMP OSes, with 720p video playback and embedded level 25fps 3D performance in around 2.5 watts at 28nm, is designed to address that imbalance. Links and details on the Libre RISC-V SoC wiki.
The real question is: why is this project the only one of its kind, and why has no well funded existing Fabless Semiconductor Company tried something like this before? The benefits to businesses of having full source code are already well-known.

Phoronix and The Register have an insightful look into an effort by ARM that is reminiscent of Microsoft's "Get The Facts" campaign. RISC-V's design is a revamp of the RISC concept that is intended from the ground up to fix the mistakes and learn from the lessons of the past 30 years. Power efficiency is 40% better than ARM or Intel. Compressed instructions reduce I-cache misses by 20-25%, which is roughly comparable to the same performance that would be achieved by doubling the Instruction Cache size. Yet despite El Reg's insightful analysis,
all is not as it seems: on further investigation, some of ARM's criticism has merit, whilst some of it is clear out-and-out FUD from ARM that, being so critically dependent on free software, had its own employees complain so much that the site was pulled.
Also we cannot help but wonder which "Big Chip" company offered seven-figure salaries to try to shut down the IIT Madras Shakti Project. Most interesting however is the fact that ARM — a $40 billion dollar company — is rattled by RISC-V enough to use underhanded tactics, whilst Intel on the other hand is actually investing.

The EOMA68 Crowd-funding campaign launched last month and has just reached $50,000 and so far has 541 backers with 28 days still to go. EOMA68 and its creator have featured regularly on slashdot over the past five years: a live-streamed video from Hope2016 explains what it's about, and there is a huge range of discussions and articles online. The real burning question is: if a single Software Libre Engineer can teach themselves PCB design and bring modular computing to people on the budget available from a single company, why are there not already a huge number of companies doing modular upgradeable hardware?

The introduction of systemd has unilaterally created a polarisation of the GNU/Linux community that is remarkably similar to the monopolistic power position wielded by Microsoft in the late 1990s. Choices were stark: use Windows (with SMB/CIFS Services), or use UNIX (with NFS and NIS). Only the introduction of fully-compatible reverse-engineered NT Domains services corrected the situation. Instructions on how to remove systemd include dire warnings that "all dependent packages will be removed", rendering a normal Debian Desktop system flat-out impossible to achieve. It was therefore necessary to demonstrate that it is actually possible to run a Debian Desktop GUI system (albeit an unusual one: fvwm) with libsystemd0 removed. The reason for doing so: it doesn't matter how good systemd is believed to be or in fact actually is: the reason for removing it is, apart from the alarm at how extensive systemd is becoming (including interfering with firewall rules), it's the way that it's been introduced in a blatantly cavalier fashion as a polarised all-or-nothing option, forcing people to consider abandoning the GNU/Linux of their choice and to seriously consider using FreeBSD or any other distro that properly respects the Software Freedom principle of the right to choose what software to run. We aren't all "good at coding", or paid to work on Software Libre: that means that those people who are need to be much more responsible, and to start — finally — to listen to what people are saying. Developing a thick skin is a good way to abdicate responsibility and, as a result, place people into untenable positions.

In an open letter to the core developers behind OpenLDAP (Howard Chu) and Python-LMDB (David Wilson) is a story of a successful creation of a high-performance task scheduling engine written (perplexingly) in python. With only partial optimisation allowing tasks to be executed in parallel at a phenomenal rate of 240,000 per second, the choice to use Python-LMDB for the per-task database store based on its benchmarks as well as its well-researched design criteria turned out to be the right decision. Part of the success was also due to earlier architectural advice gratefully received here on slashdot. What is puzzling though is that LMDB on wikipedia is being constantly deleted, despite its "notability" by way of being used in a seriously-long list of prominent software libre projects, which has been, in part, motivated by the Oracle-driven BerkeleyDB license change. It would appear that the original complaint about notability came from an Oracle employee as well...

After the reports on SSD reliability and after experiencing a costly 50% failure rate on over 200 remote-deployed OCZ Vertex SSDs, a degree of paranoia set in where I work. I was asked to carry out SSD analysis with some very specific criteria: budget below £100, size greater than 16Gbytes and Power-loss protection mandatory. This was almost an impossible task: after months of searching the shortlist was very short indeed. There was only one drive that survived the torturing: the Intel S3500. After more than 6,500 power-cycles over several days of heavy sustained random writes, not a single byte of data was lost. Crucial M4: fail. Toshiba THNSNH060GCS: fail. Innodisk 3MP SATA Slim: fail. OCZ: epic fail. Only the end-of-lifed Intel 320 and its newer replacement the S3500 survived unscathed. The conclusion: if you care about data even when power could be unreliable, only buy Intel SSDs.

Rhombus Tech and QiMod have working samples of the first EOMA-68 CPU Card, featuring 1GByte of RAM, an A10 processor and stand-alone (USB-OTG-powered with HDMI output) operation. Upgrades will include the new Dual-Core ARM Cortex A7, the pin-compatible A20. This is the first CPU Card in the EOMA-68 range: there are others in the pipeline (A31, iMX6, jz4760 and a recent discovery of the Realtek RTD1186 is also being investigated).
The first product in the EOMA-68 family, also nearing a critical phase in its development, will be the KDE Flying Squirrel, a 7in user-upgradeable tablet featuring the KDE Plasma Active Operating System. Laptops, Desktops, Games Consoles, user-upgradeable LCD Monitors and other products are to follow.
And every CPU that goes into the products will be pre-vetted for full GPL compliance, with software releases even before the product goes out the door. That's what we've promised to do: to provide Free Software Developers with the opportunity to be involved with mass-volume product development every step of the way. We're also on the look-out for an FSF-Endorseable processor which also meets mass-volume criteria which is proving... challenging.
