• Red Hat ☛ New in MicroShift 4.20: The generic device plug-in

  MicroShift is a small form factor Kubernetes distribution for edge devices that can be found as part of Red Bait Device Edge. We just released Red Bait build of MicroShift 4.20, which adds new features and capabilities like support for cert-manager, a component that simplifies certificate management for endpoints and APIs.

  This blog focuses on a key new capability: support for a generic device plug-in. Let’s explore the benefits of a generic device plug-in and see how it works.

• Red Hat Official ☛ Your complete guide for getting started with Red Hat OpenShift Virtualization

  Migrating off your current hypervisor doesn't have to be a sudden leap. It is a gradual evolution, and Red Hat provides you with guided resources at every stage of the journey. That starts with free trials and learning hubs to support your initial exploration. These tools help you build confidence early on, and smoothly transition into expert-led implementation when you're ready to apply your knowledge in real-world scenarios. This ensures a steady, predictable path toward operational success.

  Meanwhile, the public cloud has continued to gain traction in the broader compute marketplace, offering tremendous flexibility and dynamic infrastructure. This trend has been emerging as well for HPC, with organizations looking to take advantage of that same flexibility and extra compute capacity in order to scale HPC clusters on demand, shortening their product development or research cycles.

• Red Hat ☛ Exhaustive profiling toolkit: elfutils and libdwfl_stacktrace

  Various (good enough) 80% solutions (i.e., framepointer unwinding and SFrame) have tended to dominate the GNU/Linux stack profiling landscape. These proved simple to implement and deploy compared to 20% solutions (e.g., elfutils) that use CFI for more exhaustive profile coverage, including coverage of difficult control-flow sections (e.g., function prologues and epilogues, unusual ABIs). This article discusses the libdwfl_stacktrace initiative to make the elfutils project easier to use for stack profiling and examines ideas for further work, including potential improvements to the kernel’s perf_events infrastructure to benefit both 80% and 20% profiling solutions.
