Filed under
Linux

Ka-Ro’s 27 x 27mm, soldered-down “QSMP” module runs Linux on a Cortex-A7 based STM32MP1 with up to 512MB DDR3L, 4GB eMMC, and an optional dev kit. A recent i.MX8M Mini and Nano based QS8M with the same QFN form factor ships with an RPi-style devkit.

German embedded vendor Ka-Ro Electronics has launched a QFN-style, solder-down module with industrial temperature support that is available from Direct Insights in the UK and Mouser in the US starting at $30. The 27 x 27 x 3mm QSMP Series module runs Linux on a single-or dual-core, Cortex-A7 ST32M1 clocked at 650MHz with a 209MHz Cortex-M4 CPU. Other tiny ST32M1 modules include Kontron’s 25.4 x 25.4mm SOM-STM32MP157 and Octavo’s 18 x 18mm OSD32MP15x SiP module.

Graphics/Benchmarks
Linux

A year and a half later, it turns out this lightweight Mir desktop is still being worked on by lead Mir developer Alan Griffiths. Through his recent experiments with EGMDE on the latest Mir code-base, there is now improved keyboard shortcut handling, optional support for workspaces, optional support for shell components, and other changes.

Griffiths outlined the latest EGMDE process on Ubuntu Discourse for those interested. He did note, however, "egmde is still not ready for use as a lightweight desktop."

My unusual path to Linux system administration

Filed under
Linux

This is something that I say a lot and I find it to be true in nearly every aspect of life. I spent a lot of time searching for what I wanted in life. Most of us want the same thing—to love, to be loved, to grow, and to explore. So we work hard to build something of ourselves to make a better tomorrow by doing it today. We all go through hardships in life and come out the other end, but it's up to us if we end up better than we were before.

This is the story of how I became something more by doing more.

Linux at Home: Embroidery design

Filed under
Linux

In this series, we look at a range of home activities where Linux can make the most of our time at home, keeping active and engaged. The change of lifestyle enforced by Covid-19 is an opportunity to expand our horizons, and spend more time on activities we have neglected in the past.

We’ve seen welcome relief in the past few weeks in European countries, with marked declines in Covid-19 associated deaths. However, with the threat of a second wave looming in many European countries, and the pandemic remaining rampant in other parts of the world, social distancing looks set to remain for the foreseeable future.

With more time at home, there’s never a better opportunity to embark on a new hobby. How about embroidery? Learning embroidery doesn’t have to be complicated, and it definitely shouldn’t feel like a huge investment of time and money. It’s actually an easy and inexpensive hobby. And there’s good free and open source software available that helps a lot with creating and modifying embroidery designs.

STMicro STM32MP1 Cortex A7/M4 processor was launched last year with support for Linux and Android. Since then we’ve seen a few STM32MP1 SBC‘s, development kit and modules, with some of the latter really compact with DHCOR STM32MP157 SoM found on Avenger96 board measuring just 29x29mm.

Direct Insight has now unveiled QFN-style solder-down QSMP systems-on-module based on STM32MP1 that measure just 27 x 27 x 2.3mm and manufactured in Germany by Ka-Ro Electronics.

Linux Kernel and NVIDIA Vulnerabilities Patched in Ubuntu 20.04 LTS, 19.10 and 18.04 LTS

Filed under
Linux
Security
Ubuntu

Canonical released today new security updates for the Linux kernel and NVIDIA graphics drivers to address several vulnerabilities in several of the supported Ubuntu Linux releases.

The new security patches address three vulnerabilities affecting Ubuntu 20.04 LTS, Ubuntu 19.10 and Ubuntu 18.04 LTS. These include a vulnerability (CVE-2020-5963) discovered by Thomas E. Carroll in the NVIDIA Cuda grpahics driver, which could allow an attacker to cause a denial of service or possibly execute arbitrary code.

The other two security issues were an unspecified vulnerability (CVE-2020-5973) discovered in the NVIDIA virtual GPU guest drivers that could potentially lead to privileged operation execution and a race condition (CVE-2020-5967) discovered in the UVM driver in the NVIDIA graphics driver. Both these vulnerabilities could allow a local attacker to cause a denial of service.

Android Leftovers

XFS / EXT4 / Btrfs / F2FS / NILFS2 Performance On Linux 5.8

Given the reignited discussions this week over Btrfs file-system performance stemming from a proposal to switch Fedora on the desktop to using Btrfs, here are some fresh benchmarks of not only Btrfs but alongside XFS, EXT4, F2FS, and for kicks NILFS2 was also tossed into the mix for these mainline file-system tests off the in-development Linux 5.8 kernel. With the yet-to-be-approved proposal specifically to use Btrfs for desktop installations, for this testing a single NVMe solid-state drive was used for testing in jiving with conventional desktop use-cases rather than any elaborate RAID setups, etc. Each of the tested file-systems were carried out with the default mount options in an out-of-the-box manner.

Proprietary Software Leftovers

  • Ransomware Gangs Don’t Need PR Help

    Overall, I’ve tried to use each story to call attention to key failures that frequently give rise to ransomware infections, and to offer information about how other companies can avoid a similar fate.

    But simply parroting what professional extortionists have posted on their blog about victims of cybercrime smacks of providing aid and comfort to an enemy that needs and deserves neither.

  • Ransomware gangs are doing their homework before encrypting corporate data

    In the last three months, the criminal hackers behind the Maze ransomware have attacked two big IT service providers, one of which is a Fortune 500 company. Other ransomware gangs have hit big corporate targets, and in so doing are first locking computer systems and then publicly shaming companies that don’t pay up by dumping their data.

    For corporations that do pay the ransom, the pain sometimes isn’t over. There is no guarantee that the decryption key handed over by the attacker works, said Wendi Whitmore, global lead at IBM Security X-Force.

  • Zoom Will Offer End-To-End Encryption To All Its Users [Ed: But no. You cannot trust proprietary software to do what it claims to do.]

    The pandemic has moved more activities online--and specifically onto Zoom--than ever before. For an enterprise tool like Zoom, that means new users that the company never expected and did not design for, and all the unanticipated security and privacy problems that come with that sudden growth. Zoom's decision to offer end-to-end encryption more widely is especially important because the people who cannot afford enterprise subscriptions are often the ones who need strong security and privacy protections the most. For example, many activists rely on Zoom as an organizing tool, including the Black-led movement against police violence. To use Zoom's end-to-end encryption, free users will have to provide additional information, like a phone number, to authenticate. As Zoom notes, this is a common method for mitigating abuse, but phone numbers were never designed to be persistent all-purpose individual identifiers, and using them as such creates new risks for users. In different contexts, Signal, Facebook, and Twitter have all encountered disclosure and abuse problems with user phone numbers. At the very least, the phone numbers that users give Zoom should be used only for authentication, and only by Zoom. Zoom should not use these phone numbers for any other purpose, and should never require users to reveal them to other parties.

  • Desklab Portable USB-C Monitor

    I bought a mini-DisplayPort to HDMI adapter and for my first test ran it from my laptop, it was seen as a 1920*1080 DisplayPort monitor. The adaptor is specified as supporting 4K so I don’t know why I didn’t get 4K to work, my laptop has done 4K with other monitors. The next thing I plan to get is a VGA to HDMI converter so I can use this on servers, it can be a real pain getting a monitor and power cable to a rack mounted server and this portable monitor can be powered by one of the USB ports in the server. A quick search indicates that such devices start at about $12US. The Desklab monitor has no markings to indicate what resolution it supports, no part number, and no serial number. The only documentation I could find about how to recognise the difference between the FullHD and 4K versions is that the FullHD version supposedly draws 2A and the 4K version draws 4A. I connected my USB Ammeter and it reported that between 0.6 and 1.0A were drawn. If they meant to say 2W and 4W instead of 2A and 4A (I’ve seen worse errors in manuals) then the current drawn would indicate the 4K version. Otherwise the stated current requirements don’t come close to matching what I’ve measured.

Raspberry Pi 4's Vulkan Driver and More

  • Alejandro Piñeiro: v3dv status update 2020-07-01

    Input attachment is one of the main sub-features for Vulkan multipass, and we’ve gained support since the announcement. On Vulkan the support for multipass is more tightly supported by the API. Renderpasses can have multiple subpasses. These can have dependencies between each other, and each subpass define a subset of “attachments”. One attachment that is easy to understand is the color attachment: This is where a given subpass writes a given color. Another, input attachment, is an attachment that was updated in a previous subpass (for example, it was the color attachment on such previous subpass), and you get as a input on following subpasses. From the shader POV, you interact with it as a texture, with some restrictions. One important restriction is that you can only read the input attachment at the current pixel location. The main reason for this restriction is because on tile-based GPUs (like rpi4) all primitives are batched on tiles and fragment processing is rendered one tile at a time. In general, if you can live with those restrictions, Vulkan multipass and input attachment will provide better performance than traditional multipass solutions. If you are interested in reading more details on this, you can check out ARM’s very nice presentation “Vulkan Multipass mobile deferred done right”, or Sascha Willems’ post “Vulkan input attachments and sub passes”. The latter also includes information about how to use them and code snippets of one of his demos. For reference, this is how the input attachment demos looks on the rpi4...

  • Raspberry Pi 4's Vulkan Driver Is Now More Usable - Supporting More Features

    The "V3DV" Vulkan driver being developed by Igalia under contract with the Raspberry Pi Foundation has offered a status update on this official driver for the Raspberry Pi 4. The V3DV effort is the modern, official Vulkan driver for the Raspberry Pi 4 and not to be confused with the third-party Vulkan driver for pre-RPi4 hardware or the former Raspberry Pi 4 Vulkan effort. This is the new driver being developed and what ultimately will be the official driver option moving forward.
