RADV Reworking Pipeline Emitting To Improve CPU Usage

Monday 29th of January 2018 04:36:26 PM
While using Vulkan lowers the CPU utilization compared to OpenGL, in our testing of NVIDIA versus the open-source Radeon drivers we generally have found the red team's drivers to consume more CPU resources. Thus it's good to hear that RADV co-conspirator Bas Nieuwenhuizen is working on reworking how this Radeon Vulkan driver handles pipeline emitting...

It's Going To Take More Time To Get Vega Compute Support With The Mainline Kernel

Monday 29th of January 2018 11:00:00 AM
This weekend I wrote how the AMDKFD discrete GPU support should be in place for the next kernel cycle, Linux 4.17. This is going to allow discrete Radeon GPUs to have ROCm working off the mainline kernel for OpenCL/compute support, but for 4.17 it's unlikely RX Vega GPUs will have compute working...

  • Comment: Many happy returns to open source
    Twenty years ago the phrase “open source” was first used and the development of software – and hardware – was changed forever. Very few designers today will not use some element of open source software in their development projects.

  • Worth seeing in Barcelona: Open source for white box vRAN solutions
    News this week from cloud and carrier infrastructure platform company Kontron builds on our earlier coverage of the emerging virtual radio access network (vRAN); a promising technology that could help the evolution to 5G by maximising available bandwidth while lowering costs. The market for open vRAN solutions is gaining wider acceptance as operators seek more cost-effective approaches to network architectures and deployment. According to analyst firm Research and Markets, the growth of the vRAN market is expected to grow at a CAGR of approximately 125 per cent during the next three years.

  • Earlham Institute releases open source software to help identify gene families
    Researchers at Earlham Institute (EI) have released ‘GeneSeqToFamily’, an open-source Galaxy workflow that helps scientists to find gene families based on the ‘EnsemblCompara GeneTrees’ pipeline. Published in Gigascience, the open source Galaxy workflow aims to make researchers job of finding find gene families much easier.
  • 3 reasons to say 'no' in DevOps
    DevOps, it has often been pointed out, is a culture that emphasizes mutual respect, cooperation, continual improvement, and aligning responsibility with authority. Instead of saying no, it may be helpful to take a hint from improv comedy and say, "Yes, and..." or "Yes, but...". This opens the request from the binary nature of "yes" and "no" toward having a nuanced discussion around priority, capacity, and responsibility.
  • 5 rules for having genuine community relationships
    As I wrote in the first article of this three-part series on the power and importance of communities, building a community of passionate and committed members is difficult. When we launched the NethServer community, we realized early that to play the open source game, we needed to follow the open source rules. No shortcuts. We realized we had to convert the company in an open organization and start to work out in the open.

  • Rust Typestates
    A long time ago, the Rust language was a language with typestate. Officially, typestates were dropped long before Rust 1.0. In this entry, I’ll get you in on the worst kept secret of the Rust community: Rust still has typestates.
  • It's Time To Do CMake Right
    Not so long ago I got the task of rethinking our build system. The idea was to evaluate existing components, dependencies, but most importantly, to establish a superior design by making use of modern CMake features and paradigms. Most people I know would have avoided such enterprise at all costs, but there is something about writing find modules that makes my brain release endorphins. I thought I was up for an amusing ride. Boy was I wrong.

OpenBSD Gets Mitigated For Meltdown CPU Vulnerability

  • OpenBSD Gets Mitigated For Meltdown CPU Vulnerability
    A few days back FreeBSD 11 stable was mitigated for Meltdown (and Spectre vulnerabilities), which came more than one month after these nasty CPU vulnerabilities were disclosed while DragonFlyBSD was quickly mitigated and the first of the BSDs to do so. While OpenBSD is known for its security features and focus, only today did it land its initial Meltdown mitigation.
  • Meltdown fix committed by guenther@

    Meltdown mitigation is coming to OpenBSD. Philip Guenther (guenther@) has just committed a diff that implements a new mitigation technique to OpenBSD: Separation of page tables for kernel and userland. This fixes the Meltdown problems that affect most CPUs from Intel. Both Philip and Mike Larkin (mlarkin@) spent a lot of time implementing this solution, talking to various people from other projects on best approaches.

    In the commit message, Philip briefly describes the implementation [...]

France Proposes Software Security Liability For Manufacturers, Open Source As Support Ends

It sometimes seems as though barely a week can go by without yet another major software-related hardware vulnerability story. As manufacturers grapple with the demands of no longer building simple appliances but instead supplying them containing software that may expose itself to the world over the Internet, we see devices shipped with insecure firmware and little care for its support or updating after the sale. The French government have a proposal to address this problem that may be of interest to our community, to make manufacturers liable for the security of a product while it is on the market, and with the possibility of requiring its software to be made open-source at end-of-life. In the first instance it can only be a good thing for device security to be put at the top of a manufacturer’s agenda, and in the second the ready availability of source code would present reverse engineers with a bonanza.
