  • Radeon RX Vega Display Regression Fix Heading To Linux 4.18 Git

    If you have been part of the group of Radeon RX Vega Linux users trying out Linux 4.18 and finding your display no longer lights up, heading to Linux 4.18 Git should be a fix for at least some of the users.

    Sent out on Friday was a batch of AMDGPU DRM-Fixes-4.18. It's just three fixes, but two of them are pertaining to display problems and the other a segmentation fault if the GPU does not power up properly when resuming the system.

ARM Takes Down Its Website That Attacked Open-Source Rival

Filed under
Hardware

ARM, the incredibly successful developer of CPU designs, appears to be getting a little nervous about an open-source rival that’s gaining traction. At the end of June, ARM launched a website outlining why it’s better than its competitor’s offerings and it quickly blew up in its face. Realising the site was a bad look, ARM has now taken it down.

For the uninitiated, ARM Holdings designs various architectures and cores that it licenses to major chipmakers around the world. Its tech can be found in over 100 billion chips manufactured by huge names like Apple and Nvidia as well as many other lesser-known players in the low-power market. If ARM is Windows, you can think of RISC-V as an early Linux. Like ARM, it’s an architecture based on reduced instruction set computing (RISC), but it’s free to use and open to anyone to contribute or modify. While ARM has been around since 1991, RISC-V just got started in 2010 but it’s gaining a lot of ground and ARM’s pitiful website could easily be seen as a legitimising moment for the tech.

Fedora on the UDOO Neo

HowTos

The core support for the i.MX6SX SoC and the UDOO Neo is pretty reasonable, with the MMC fixes it’s been very stable, all the core bits are working as expected, included wired and wireless network, thermal, cpufreq, crypto and it looks like the display should work fine. There’s a few quirks that I need to investigate further which should provide for a fun evening or weekend hacking. There has also been recently merged support for the i.MX6SX Cortex-M4 land upstream in Zephyr upstream for the 1.13 release, so getting that running and communication using Open-AMP between Fedora and Zephyr should also be an interesting addition. I think this will be a welcome addition to Fedora 29, and not a moment too soon!!

  • A Landmark Legal Shift Opens Pandora’s Box for DIY Guns

     

    Two months ago, the Department of Justice quietly offered Wilson a settlement to end a lawsuit he and a group of co-plaintiffs have pursued since 2015 against the United States government. Wilson and his team of lawyers focused their legal argument on a free speech claim: They pointed out that by forbidding Wilson from posting his 3-D-printable data, the State Department was not only violating his right to bear arms but his right to freely share information. By blurring the line between a gun and a digital file, Wilson had also successfully blurred the lines between the Second Amendment and the First.

     

    "If code is speech, the constitutional contradictions are evident," Wilson explained to WIRED when he first launched the lawsuit in 2015. "So what if this code is a gun?”

ARM Launches "Facts" Campaign Against RISC-V

Filed under
Hardware

It looks like Arm Limited is going on the offensive against the RISC-V open-source processor instruction set architecture.

ARM has launched RISCV-Basics.com as a site to "understanding the facts" about the RISC-V architecture.

Their five points they try to make before designing a SoC is that the ISA accounts for only a small portion of the total investment to creating a commercial processor, RISC-V doesn't yet have an a large developer ecosystem, there is the risk of fragmentation with this open-source ISA, RISC-V is new and thus not yet as mature in terms of being a proven architecture around security, and greater design costs with RISC-V due to potential re-validation if modifying the ISA.

SiFive To Release Code As Open-Source For Fully Initializing The RISC-V Board

Filed under
Hardware
OSS

Last week we noted how some of the code to boot the RISC-V SiFive HiFive Unleashed development board was closed-source. That upset some in the Coreboot community with hoping for a more open development board built around the RISC-V open-source processor ISA. The good news is that SiFive will soon be releasing the necessary code for initialization as open-source.

The code for initializing the DDR controller was not open-source and SiFive believed they could not open-source it. The good news is that SiFive has discovered they will be able to open-source it.

OSS: Apache Cassandra, Jib,WSO2 and More

  • Apache Cassandra at 10: Making a community believe in NoSQL
    Ten years ago this month, when Lehman Brothers was still just about in business and the term NoSQL wasn't even widely known, let alone an irritant, Facebook engineers open-sourced a distributed database system named Cassandra. Back then, the idea that huge numbers of companies would need a scalable database was almost laughable – and that grip of traditional relational database systems is reflected in the mythical moniker given to what would become one of the first of many databases designed to run on a cluster of machines. Named after the Greek figure who was cursed to utter the truth but was never believed, Cassandra might seem an odd choice for a system whose raison d'être is believability – but it delivered a nice dig at the stalwarts of the RDBMS world… and their trust in a false Oracle.
  • Google Launches Jib, Automated Container Packaging for Java Apps
    Google has released software that could automate the packaging of a Java program so that it can be run in the cloud-native environment. Jib is an open-source Java “containerizer,” one that handles all the steps of packaging your application into a container image, according to Appu Goundan and Qingyang Chen, two Google engineers who co-wrote a blog post announcing the new technology. Created over two decades ago at Sun Microsystems, Java was introduced as a “write once, run anywhere” programming language, where all the code would be packaged in a JAR file, and run by a Java Virtual Machine on any platform. The requirements for running code anywhere have expanded with the introduction of containerization, however. Few shops are Java-only these days, and many are turning to containerization for true application portability,

The PDS scheduler stands for the "Priority and Deadline based Skiplist multiple queue scheduler" that is derived from Con Kolivas' former BFS scheduler with Variable Run Queue (VRQ) support. PDS design principles are to be a simple CPU process scheduler yet efficient and scalable. PDS-mq differs from Con Kolivas' current MuQSS scheduler.
  • Add infrastructure for Vblank and page flip events in vkms simulated by hrtimer
    Since the beginning of May 2018, I have been diving into the DRM subsystem. In the beginning, nothing made sense to me, and I had to fight hard to understand how things work. Fortunately, I was not alone, and I had great support from Gustavo Padovan, Daniel Vetter, Haneen Mohammed, and the entire community. Recently, I finally delivered a new feature for VKMS: the infrastructure for Vblank and page flip events. At this moment, VKMS have regular Vblank events simulated through hrtimers (see drm-misc-next), which is a feature required by VKMS to mimic real hardware [6]. The development approach was entirely driven by the tests provided by IGT, more specifically the kms_flip. I modified IGT to read a module name via command line and force the use of it, instead of using only the modules defined in the code (patch submitted to IGT, see [1]). With this modification in the IGT, my development process to add a Vblank infrastructure to VKMS had three main steps as Figure 1 describes.

    While the RadeonSI and Intel i965 Mesa drivers have been at OpenGL 4.5 compliance for a while now, the Nouveau "NVC0" Gallium3D driver has been bound to OpenGL 4.3 officially. This Nouveau Gallium3D driver for NVIDIA "Fermi" graphics hardware and newer has effectively supported all of the OpenGL 4.4/4.5 extensions, but not officially. Originally the NVC0 problem for OpenGL 4.4 and newer was the requirement of passing the OpenGL Conformance Test Suite (CTS), which at first wasn't open-source. But now The Khronos Group has made it available to everyone as open-source. Additionally, the proper legal wrangling is in place so the Nouveau driver could become a conforming Khronos adopter under the X.Org Foundation without any associated costs/fees with Nouveau being purely open-source and primarily considered a community driver.
