  • xf86-video-amdgpu 21.0.0 Released For Radeon Linux Users Still On X.Org

    It's been one year since the last xf86-video-amdgpu release in the form of v19.1 and about two years since the release before that with v19.0... Now the xf86-video-amdgpu 21.0 driver is ready for those who need it. As with all open-source Linux graphics drivers, these X.Org DDX releases are of little value these days given the migration to Wayland and those sticking to X.Org most often just using the generic xf86-video-modesetting driver. All the interesting open-source graphics magic these days happen within the DRM/KMS kernel driver components and Mesa. But unlike Intel who hasn't even issued a new xf86-video-intel development release in six years or going back seven years to the last stable release, AMD does still put out the yearly or so DDX update.

Kernel: AMX, OpenZFS, and AMDGPU

  • Intel AMX Support Appears Ready For Linux 5.16 - Phoronix

    It's been over one year since Intel disclosed Advanced Matrix Extensions and began posting patches for bringing up AMX support under Linux in anticipation of Xeon Scalable "Sapphire Rapids" processors. While the compiler-side work to GCC and LLVM/Clang has been landing, finally with the forthcoming Linux 5.16 cycle that AMX support appears ready for landing. Merged today to tip/tip.git's "x86/fpu" branch where kernel FPU changes are queued ahead of the next merge window, the last of the AMX enablement patches were queued up. Most notably, the work for actually enabling the AMX feature and being able to expose it to user-space via the new interface.

  • BLK-MQ Support For OpenZFS Pending As Latest Performance Optimization

  • Should you use Docker on your VPS server? - The Jerusalem Post

    Unlike other popular tools that can trace their roots back to the nineties or even earlier, Docker didn't exist until 2013. Yet, in a very short period of time, it has managed to become something of a household name (assuming the household consists primarily of IT specialists). But what is Docker exactly? How did it manage to become so popular so quickly? And how can you deploy it on your VPS? Let's find out.

  • Sending logs to Humio using the elasticsearch-http() destination of syslog-ng - Blog - syslog-ng Community - syslog-ng Community

    One of the most popular syslog-ng destinations is Elasticsearch. Humio, a log management provider, supports a broad range of ingest options and interfaces, including an Elasticsearch-compatible API. Last week, Humio announced Humio Community Edition, which provides the full Humio experience for free, with some limitations on daily ingestion and retention time. I tested the Community Edition, and it works perfectly well with syslog-ng. If you come from the Humio side, you might wonder what syslog-ng is. It is an application for high performance central log collection. Traditionally, syslog messages were collected centrally and saved to text files. Nowadays, syslog-ng acts more like a log management layer: collects log messages from hosts, saves them for long term storage, but also forwards them to multiple destinations, like SIEMs and other log analysis solutions. This way, it is enough to collect log messages only once, and syslog-ng delivers the right log messages to the right destinations in the right format, after some initial processing. Humio is available as a cloud service or self-hosted, where you can send all your logs for storage and analysis. It has an easy-to-use interface to query log messages which can be extended with further analytics possibilities from the Humio marketplace. From this blog, you can learn how to get started with Humio and syslog-ng. While Humio provides many other APIs for log ingestion, I focus on the elasticsearch-http() destination of syslog-ng, demonstrating that there is no vendor lock-in: the same driver works equally well for Elastic’s Elasticsearch, AWS’s OpenSearch and for Humio.

  • Deploy Quarkus applications to Kubernetes using a Helm chart | Opensource.com

    Serverless functions are driving the fast adoption of DevOps development and deployment practices today. Knative on Kubernetes is one of the most popular serverless platforms to adopt serverless function architectures successfully. But developers must understand how serverless capabilities are specified using a combination of Kubernetes APIs, Knative resources, and function-oriented programming. DevOps teams also need to standardize runtime stacks (that is, application runtime, builder image, deployment configuration, and health check) to execute the functions on Kubernetes. What if you, a developer, could set this up with familiar technology and practice? This article guides you on the way developers can get started with serverless function deployment with the Quarkus Helm chart on Kubernetes. Furthermore, developers can avoid the extra work of developing a function from scratch, optimizing the application, and deploying it to Kubernetes. If you haven't experienced using Helm for cloud-native application deployments on Kubernetes, I will tell you what Helm is and what benefits you have with it. Helm is one of the most popular package managers for Kubernetes. Helm provides a chart that simplifies Kubernetes resources within a single package file for an application build and deployment. Developers can install the chart to Kubernetes using the Helm command-line interface or graphical dashboard.
