Year 2020 in review – Top ten posts and stats

CNX Software Year 2021

It’s this time of the year when we look back at what happened, and what may be next. 2020 did not pan out as planned in more ways than one, but there were still some interesting developments. Based on 2019 announcements, 2020 was promising to be an exciting year for Amlogic and Rockchip with the expected launch of RK3588 and S908X high-end processors for 8K capable devices,  but we’ll have to wait for 2021 for this to happen. Instead, the most interesting processor of the year from the Allwinner, Amlogic, and Rockchip offerings was probably Amlogic S905X4 processing adding AV1 hardware decoding. As pointed out in our “RISC-V 2020 highlights” post, it was a fairly eventful year for RISC-V architecture, although there’s still a long road ahead, especially for application processors. We had seen some general-purpose and Bluetooth RISC-V MCUs in 2019, but 2020 saw the launch of the first […]

Linux 5.10 LTS release – Main changes, Arm, MIPS and RISC-V architectures

Linux 5.10 release

Linus Torvalds has just released Linux 5.10: Ok, here it is – 5.10 is tagged and pushed out. I pretty much always wish that the last week was even calmer than it was, and that’s true here too. There’s a fair amount of fixes in here, including a few last-minute reverts for things that didn’t get fixed, but nothing makes me go “we need another week”. Things look fairly normal. It’s mostly drivers – as it should be – with a smattering of fixes all over: networking, architectures, filesystems, tooling.. The shortlog is appended, and scanning it gives a good idea of what kind of things are there. Nothing that looks scary: most of the patches are very small, and the biggest one is fixing pin mapping definitions for a pincontrol driver. This also obviously means that the merge window for 5.11 will start tomorrow. I already have a couple […]

Mesa 20.3 released with Raspberry Pi 4 V3DV driver, Panfrost Bifrost support

Mesa 20.3 Raspberry Pi 4 Mali Bifrost

We’ve previously reported that the Vulkan 1.0 conformant V3DV driver for Raspberry Pi 4 and other Broadcom BCM2711 based platforms was part of Mesa 20.3 open-source graphics framework. But at the time, it was still under development. The good news is that Mesa 20.3 has now been released, and there’s much more than Raspberry Pi 4 support, as Collabora informed us the release also included Arm Mali Bifrost GPU support via the open-source Panfrost driver. The latter was made possible thanks to the work by Alyssa Rosenzweig and Boris Brezillon, with Alyssa going into details in a recent blog post on Collabora. More work is still needed with better performance and OpenGL 3.1 being the focus in the months ahead. But there were also many other changes in Mesa 20.3 as reported by Phoronix: OpenGL 4.6 and Vulkan 1.2 APIs support Initial support for Intel Gen12 Alder Lake graphics and […]

DevTerm with ClockworkPi v3.14: a modular, portable computer

DevTerm Portable Computer

After the launch of ClockworkPi GameShell in Q4 2018, now ClockworkPi has come with yet another exciting product. DevTerm is a portable computer that comes with a 6.8-inch IPS screen, a keyboard with 67 keys, and a battery module, all connected to ClockworkPi v3.14 carrier board and a choice of core modules. It will also come with an optional built-in thermal printer. ClockworkPi v3.14 Mainboard and the Core boards The mainboard ClockworkPi v3.14 uses a compact design and comes with a reduced size of 95x77mm. With a modular design, it gives you a choice of “core board” modules for various applications. Moreover, ClockworkPi v3.14 is now compatible with the Raspberry Pi CM3 series, which means that your work on the Raspberry Pi can be “teleported” to a portable terminal without hassle. It has integrated 5GHz WIFI (802.11ac) and Bluetooth 5.0 which makes it suitable for wireless communication applications as well. […]

Arm Cortex-A78C core supports up to 8 cores per cluster, 8MB L3 cache for always-on laptops

Arm Cortex-A78C

[Update November 7, 2020:  Correction for the meaning of “multi-OS support” on Arm Cortex-A78AE core] Arm Cortex-A78 CPU core was first introduced in May 2020 with a focus on mobile devices like smartphones and was followed by Cortex-A78AE for automotive and industrial embedded applications in September. The company has now introduced a new variant with Arm Cortex-A78C supporting up to eight cores per cluster, a larger cache up to 8MB for higher performance, and advanced security features all designed for always-on laptops and other “on-the-go” devices. Arm Cortex-A78C key features and specifications: Architecture –  Armv8-A (Harvard) Extensions – Armv8.1, Armv8.2, Cryptography, and RAS; Armv8.3 (LDAPR instructions only), Armv8.3-A and Armv8.6-A Pointer Authentication support (excluding the optional FPAC extension), and Armv8.4 multi-OS support ISA support – A64, A32, and T32 (at EL0 only) Microarchitecture Pipeline – Out of order Superscalar Neon / Floating Point Unit Optional cryptography Unit Max number of […]

Arm Ethos-U65 microNPU enables low-power AI inference on Cortex-A & Neoverse SoC’s

Ethos-U65 - Cortex-M vs Cortex A/Neoverse Diagrams

Arm introduced their very first microNPU (Micro Neural Processing Unit) for microcontrollers at the beginning of the year with Arm Ethos-U55 designed for Cortex-M microcontrollers such as Cortex-M55, and delivering 64 to 512 GOPS of AI inference performance or up to a 480x increase in ML performance over Cortex-M CPU inference. The company has now unveiled an update with Arm Ethos-U65 microNPU that maintains the efficiency of Ethos-U55 but enables neural network acceleration in higher performance embedded devices powered by Arm Cortex-A and Arm Neoverse SoCs. Arm Ethos-U65 delivers up to 1 TOPS, and as seen in the diagram enables features that can not be done with Ethos-U55 including object classification and real-time classification. Compared to Ethos-N78 NPU, the new microNPU offers less AI performance, but a significantly higher efficiency although AFAIK no quantified by Arm. The company says the development workflow remains the same with the use of the […]

Linux 5.9 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linux 5.9 release

Linus Torvalds has just announced the release of Linux 5.9 on lkml: Ok, so I’ll be honest – I had hoped for quite a bit fewer changes this last week, but at the same time there doesn’t really seem to be anything particularly scary in here. It’s just more commits and more lines changed than I would have wished for. The bulk of this is the networking fixes that I already mentioned as being pending in the rc8 release notes last weekend. In fact, about half the patch (and probably more of the number of commits) is from the networking stuff (both drivers and elsewhere). Outside of that, the most visible thing is a reinstatement of the fbdev amba-clcd driver – that’s a noticeable patch, but it’s basically just mainly a revert. The rest is really really tiny (mostly some other minor driver updates, but some filesystem and architecture fixes […]
