  • Mesa Developers Discuss LTO'ing + PGO'ing Builds For Greater Performance

    Making use of Link-Time Optimizations (LTO) and Profile Guided Optimizations (PGO) is currently being talked about by Mesa developers for their release builds in potentially squeezing out better performance.

    Dieter Nützel shared that when using LTO and PGO compiler optimizations on Mesa, he's able to get RadeonSI's binary size 40% smaller and 16~20% faster for this OpenGL driver. Link-time optimizations are about as the name implies running optimization passes during the linker phase when able to analyze the to-be-produced binary in full rather than the individual object files in order to allow for more inter-procedural optimizations on the whole program.

  • Open-Source Nouveau Extended To Support The GeForce 16 Series With Hardware Acceleration

    With the big Linux 5.6 kernel on the open-source NVIDIA "Nouveau" driver side there is finally accelerated support for the GeForce RTX 2000 "Turing" graphics cards (when paired with binary-only microcode). With that initial cut support is no GeForce 16 series Turing support, but that is now on-deck for Linux 5.7.

    While the GeForce 16 series is Turing based and just without the RTX cores, firmware/microcode differences and other subtle changes were needed to the Nouveau kernel driver for enabling its open-source hardware accelerated support.

  • Radeon "sisched" Scheduler Is Made Obsolete By RADV's ACO Back-End

    It's been years since last hearing anything about sisched as the SI machine instruction scheduler that started out for the RadeonSI OpenGL driver and was ultimately supported by the RADV Vulkan driver too.

    Years ago, SISCHED helped offer better open-source AMD Radeon Linux gaming performance but those days are over. The scheduler was made part of the AMDGPU LLVM back-end and that sisched code hasn't seen any new work in ages. Now with Valve's ACO taking off so well since its mainlining in Mesa 19.3 as an alternative to the AMDGPU LLVM back-end, it pretty much nails the coffin on SISCHED.

  • Intel Blackhole Render Support Lands In Mesa 20.1

    Intel Blackhole Render support was finally merged today for the new Intel "Iris" Gallium3D OpenGL driver default, the older i965 driver for pre-Broadwell hardware, and also the Mesa state tracker for Gallium3D drivers.

    Proposed back in 2018 was the Intel blackhole render extension for OpenGL / GLES as an extension to disable all rendering operations emitted to the GPU through OpenGL rendering commands but without affecting OpenGL pipeline operations.

Servers: Kubernetes, Benchmarks and OpenStack

  • Longhorn Simplifies Distributed Block Storage in Kubernetes

    Today we’re announcing the general availability of Longhorn, an enterprise-grade, cloud-native container storage solution. Longhorn directly answers the need for an enterprise-grade, vendor-neutral persistent storage solution that supports the easy development of stateful applications within Kubernetes. We’ve been working on Longhorn for almost as long as we’ve been around as a company. We launched the project in 2017, and then in 2019, we contributed it to the Cloud Native Computing Foundation (CNCF) as a sandbox project. So it’s that CNCF open source project that is now generally available.

  • Supporting the Evolving Ingress Specification in Kubernetes 1.18

    Earlier this year, the Kubernetes team released Kubernetes 1.18, which extended Ingress. In this blog post, we’ll walk through what’s new in the new Ingress specification, what it means for your applications, and how to upgrade to an ingress controller that supports this new specification.

  • Benchmarks Of 2nd Gen AMD EPYC On Amazon EC2 Against Intel Xeon, Graviton2

    Today AMD and Amazon announced the general availability of 2nd Gen AMD EPYC "Rome" processors available via the Elastic Compute Cloud. AMD EPYC "Rome" on EC2 with the new "C5a" instance types offer very competitive performance against the latest Intel Xeon instance types, Amazon's own Graviton2 Arm-based instances, and a big upgrade compared to the first-generation EPYC processors in the cloud.

  • Antoine Beaupré: Replacing Smokeping with Prometheus

    I've been struggling with replacing parts of my old sysadmin monitoring toolkit (previously built with Nagios, Munin and Smokeping) with more modern tools (specifically Prometheus, its "exporters" and Grafana) for a while now. Replacing Munin with Prometheus and Grafana is fairly straightforward: the network architecture ("server pulls metrics from all nodes") is similar and there are lots of exporters. They are a little harder to write than Munin modules, but that makes them more flexible and efficient, which was a huge problem in Munin. I wrote a Migrating from Munin guide that summarizes those differences. Replacing Nagios is much harder, and I still haven't quite figured out if it's worth it. [...] A naive implementation of Smokeping in Prometheus/Grafana would be to use the blackbox exporter and create a dashboard displaying those metrics. I've done this at home, and then I realized that I was missing something.

  • Reproducible Builds in May 2020

    One of the original promises of open source software is that distributed peer review and transparency of process results in enhanced end-user security. Nonetheless, whilst anyone may inspect the source code of free and open source software for malicious flaws, almost all software today is distributed as pre-compiled binaries. This allows nefarious third-parties to compromise systems by injecting malicious code into seemingly secure software during the various compilation and distribution processes.

  • Steve McIntyre: Interesting times, and a new job!

    It's been over ten years since I started in Arm, and nine since I joined Linaro as an assignee. It was wonderful working with some excellent people in both companies, but around the end of last year I started to think that it might be time to look for something new and different. As is the usual way in Cambridge, I ended up mentioning this to friends and things happened! [...] Where do I fit in? Pexip is a relatively small company with a very flat setup in engineering, so that's a difficult question to answer! I'll be starting working in the team developing and maintaining PexOS, the small Linux-based platform on which other things depend. (No prizes for guessing which distro it's based on!) But there's lots of scope to get involved in all kinds of other areas as needs and interests arise. I can't wait to get stuck in! Although I'm no longer going to be working on Debian arm port issues on work time, I'm still planning to help where I can. Let's see how that works...
