  • AMD Squeezes In Some Final AMDGPU Changes To DRM-Next For Linux 4.21
    Complementing all of the AMDGPU feature work already staged for the upcoming Linux 4.21 kernel, another (small) batch of material was sent out on Wednesday. This latest AMDGPU material for Linux 4.21 includes PowerPlay updates for newer Polaris parts, a cursor plane update fast path, enabling GPU reset by default for Sea Islands (GCN 1.1) graphics cards, and various fixes.
  • AMD Adding STIBP "Always-On Preferred Mode" To Linux
    Initially during the Linux 4.20 kernel merge window with the STIBP addition for cross-hyperthread Spectre V2 mitigation it was turned on by default for all processes. But that turned out to have a sizable performance hit so the behavior was changed to only turn it on for processes under SECCOMP or when requested via the PRCTL interface. However, AMD is landing a patch that for select CPUs will have an always-on mode as evidently that's preferred for some AMD processors.
  • Radeon Software for Linux 18.50 Released - Just One Listed Change
    The Radeon Software for Linux 18.50 driver release (a.k.a. "AMDGPU-PRO" 18.50) is now officially available We were expecting the 18.50 driver update following Thursday's Radeon Software Adrenalin 2019 Edition driver for Windows having debuted. The 18.50 driver release has since been made available via the AMD web-site.
  • Radeon ROCm 1.9.1 vs. NVIDIA OpenCL Linux Plus RTX 2080 TensorFlow Benchmarks
    Following the GeForce RTX 2080 Linux gaming benchmarks last week with now having that non-Ti variant, I carried out some fresh GPU compute benchmarks of the higher-end NVIDIA GeForce and AMD Radeon graphics cards. Here's a look at the OpenCL performance between the competing vendors plus some fresh CUDA benchmarks as well as NVIDIA GPU Cloud TensorFlow Docker benchmarks.
  • Radeon Software Adrenalin 2019 Rolls Out While Linux Users Should Have AMDGPU-PRO 18.50
    AMD today released their Radeon Software Adrenalin 2019 Edition geared for Windows gamers while Linux users should have AMDGPU-PRO 18.50 available shortly for those wanting to use this hybrid Vulkan/OpenGL driver component that does also feature the AMDGPU-Open components too in their stable but dated composition. The 2019 Adrenalin Edition for Windows brings performance improvements for select Windows titles, new advisors to help configure games and settings, improved fan control, WattMan improvements, game streaming improvements, and more.

Security Leftovers

  • Thoughts on bootstrapping GHC
    I am returning from the reproducible builds summit 2018 in Paris. The latest hottest thing within the reproducible-builds project seems to be bootstrapping: How can we build a whole operating system from just and only source code, using very little, or even no, binary seeds or auto-generated files. This is actually concern that is somewhat orthogonal to reproducibility: Bootstrappable builds help me in trusting programs that I built, while reproducible builds help me in trusting programs that others built. And while they make good progress bootstrapping a full system from just a C compiler written in Scheme, and a Scheme interpreter written in C, that can build each other (Janneke’s mes project), and there are plans to build that on top of stage0, which starts with a 280 bytes of binary, the situation looks pretty bad when it comes to Haskell.

  • IBM protects your cloud container data running under Kubernetes with encryption
    Protecting your stored data on the cloud is a concern, but it's easy enough with encryption. Thanks to SSL, it's simple to protect data in motion on the network. But protecting your data when it's being used on the cloud is not so simple. Enter IBM, which, in partnership with Fortanix, is now providing data-in-use protection for your container workloads running on the IBM Cloud Kubernetes Service with IBM Cloud Data Shield. Jason McGee, IBM Cloud Platform VP and CTO, explained the process at KubeCon in Seattle: Data Shield uses Intel Software Guard Extensions (SGX) technology to run code and data in CPU-hardened Trusted Execution Environment (TEE) or enclave. This is a trusted area of memory, where critical aspects of the application functionality are protected by encryption. This helps keep both your code and data private and shielded from would-be hackers.

  • Kubernetes Security Authentication Moving Forward With SIG-Auth
    The basic units of organization within the Kubernetes community are the Special Interest Groups that help define and implement new features and capabilities. For security, one of the primary SIGs within Kubernetes is SIG-Auth. Kubernetes is a widely used container orchestration platform that is supported on all the major public cloud providers and is also deployed on-premises. In a session at the KubeCon + CloudNativeCon NA 2018 here, the leaders of SIG-Auth outlined how the group works and what the current and future priorities are for the Kubernetes project.

Slimbook & Kubuntu - Combat Report 3

And we're done. I am not sure what kind of message you're getting - or you think you're supposed to be getting from my articles. Overall, I am quite pleased with my Slimbook & Kubuntu experience. But if I had to choose, I wouldn't abandon my Windows. I simply cannot. The games, the office stuff, even simple image manipulation and text editing. All these are currently not the killer features of any which Linux desktop. That said, Kubuntu purrs nicely. Runs fast and true, and there are no crashes or errors. The desktop is extremely flexible and extensible, it's pleasing to use, and I'm having fun discovering things, even if they sometimes turn out to be bugs or annoyances. In general, it's the application side that needs to be refined, and then, the system can just become a background for you to be productive and enjoy yourselves. Until the next report. Read more
