AMD/Intel Benchmarks: Building The Mainline Linux x86_64 Kernel With LLVM Clang

Thursday 12th of September 2019 02:31:33 PM
With the upcoming LLVM Clang 9.0 compiler release there is an amazing achievement more than a decade in the making... The mainline Clang compiler can finally build the mainline Linux x86_64 kernel. The AArch64 state has been in better shape in recent years with multiple Arm vendors using Clang as their default compiler including to build the Linux kernel, but finally in 2019 the mainline Clang can build mainline Linux x86_64. There are a few caveats, but in this article is my experience in doing so with LLVM Clang and the Linux 5.3 kernel as well as running some preliminary benchmarks on AMD and Intel hardware.

  • [Mozilla] Restricting third-party iframe widgets using the sandbox attribute, referrer policy and feature policy

    Adding third-party embedded widgets on a website is a common but potentially dangerous practice. Thankfully, the web platform offers a few controls that can help mitigate the risks. While this post uses the example of an embedded SurveyMonkey survey, the principles can be used for all kinds of other widgets. Note that this is by no means an endorsement of SurveyMonkey's proprietary service. If you are looking for a survey product, you should consider a free and open source alternative like LimeSurvey.

DM-Clone Target Added To Linux 5.4 For Efficient Remote Replication Of A Block Device

Added to the device mapper (DM) code with the Linux 5.4 kernel is an interesting addition that benefits those wanting to carry out some interesting use-cases around remote replication of block devices. As explained in the original patch proposal for dm-clone, "dm-clone produces a one-to-one copy of an existing, read-only device (origin) into a writable device (clone): It presents a virtual block device which makes all data appear immediately, and redirects reads and writes accordingly. The main use case of dm-clone is to clone a potentially remote, high-latency, read-only, archival-type block device into a writable, fast, primary-type device for fast, low-latency I/O. The cloned device is visible/mountable immediately and the copy of the origin device to the clone device happens in the background, in parallel with user I/O." Read more

Of particular interest to the community was Christian Glombek’s presentation updating the status and roadmap for OKD4 and CoreOS. Highlights from the Gathering induled an OpenShift 4 Roadmap Update, customer stories from Amadeus, the leading travel technology company, and local stories from Poste Italiane and SIA S.p.A. In addition to the technical updates and customer talks, there was plenty of time to network during the breaks and enjoy the famous Italian coffee.

  • Powering the hybrid cloud on next-generation hardware: Red Hat Enterprise Linux on IBM System Z and LinuxONE

    For more than five years we have been driving our technology strategy around the idea that the future of enterprise IT does not reside solely in an enterprise datacenter or in the public cloud. Instead the next wave of computing is built on a blend of these technologies and infrastructure: in short, the future is hybrid. The value of hybrid clouds comes from the choice it delivers, pairing the control of the corporate datacenter alongside the scale and flexibility of public clouds. We strongly feel, however, that the most valuable hybrid clouds are those that offer not only a choice of deployment type and location, but also a choice of the underlying architecture and the capacity to run on multiple public clouds. [....] With RHEL available on Z15 and LinuxONE III, this helps pave the way for the rest of Red Hat’s hybrid cloud portfolio, including Red Hat OpenShift, to emerge on IBM enterprise platforms. We’re pleased to continue our work with IBM in bringing the world’s leading enterprise Linux platform to their next-generation systems.
