  • New x86 Platform Drivers Land In Linux 4.5, Including Telemetry For Apollo Lake

    Coming with Linux 4.5 is an eventful x86 platform drivers update.

    The x86 platform driver updates landed today in Linux Git and include a new Intel Telemetry platform device and driver, an Intel Telemetry core driver, an Intel P-Unit Mailbox IPC driver, a new Intel HID event driver for hot keys, and updates to the existing drivers.

  • Intel Kabylake Will Still Require Firmware Blobs

    Beginning with Skylake and Broxton hardware, Intel began requiring firmware blobs as part of their open-source graphics driver stack. This binary firmware is continuing forward with the next-generation Kabylake processors.

    With the in-development Linux 4.5 kernel there is the initial Kabylake support, but that support will be further polished over the next few kernel cycles. Published today was the GuC loading support for Kabylake, The GuC engine is for workload scheduling on parallel graphics engines and is what necessitated the firmware introduction with Skylake and Broxton. So it's not entirely a surprise that there's going to be firmware blobs for Kabylake, it would have been more surprising if they would have dropped it after just one generation.

  • 63 Mesa Patches For Wiring Up One OpenGL 4.3 Extension

    Sixty-three patches were published on the Mesa mailing list this morning for wiring up the ARB_internalformat_query2 extension as needed by OpenGL 4.3.

    Consulting firm Igalia has been working on the ARB_internalformat_query2 support for the Intel i965 DRI driver. These 63 patches posted today under a "request for comments" state implement the support for core Mesa and the Intel i965 back-end.

Early Benchmarks Of The Linux 4.9 DRM-Next Radeon/AMDGPU Drivers

While Linux 4.9 will not officially open for development until next week, the DRM-Next code is ready to roll with all major feature work having been committed by the different open-source Direct Rendering Manager drivers. In this article is some preliminary testing of this DRM-Next code as of 29 September when testing various AMD GPUs with the Radeon and AMDGPU DRM drivers. Linux 4.9 does bring compile-time-offered experimental support for the AMD Southern Islands GCN 1.0 hardware on AMDGPU, but that isn't the focus of this article. A follow-up comparison is being done with GCN 1.0/1.1 experimental support enabled to see the Radeon vs. AMDGPU performance difference on that hardware. For today's testing was a Radeon R7 370 to look at the Radeon DRM performance and for AMDGPU testing was the Radeon R9 285, R9 Fury, and RX 480. Benchmarks were done from the Linux 4.8 Git and Linux DRM-Next kernels as of 29 September. Read more

How to Effectively and Efficiently Edit Configuration Files in Linux

Every Linux administrator has to eventually (and manually) edit a configuration file. Whether you are setting up a web server, configuring a service to connect to a database, tweaking a bash script, or troubleshooting a network connection, you cannot avoid a dive deep into the heart of one or more configuration files. To some, the prospect of manually editing configuration files is akin to a nightmare. Wading through what seems like countless lines of options and comments can put you on the fast track for hair and sanity loss. Which, of course, isn’t true. In fact, most Linux administrators enjoy a good debugging or configuration challenge. Sifting through the minutiae of how a server or software functions is a great way to pass time. But this process doesn’t have to be an exercise in ineffective inefficiency. In fact, tools are available to you that go a very long way to make the editing of config files much, much easier. I’m going to introduce you to a few such tools, to ease some of the burden of your Linux admin duties. I’ll first discuss the command-line tools that are invaluable to the task of making configuration more efficient. Read more

Why Good Linux Sysadmins Use Markdown

The Markdown markup language is perfect for writing system administrator documentation: it is lightweight, versatile, and easy to learn, so you spend your time writing instead of fighting with formatting. The life of a Linux system administrator is complex and varied, and you know that documenting your work is a big time-saver. A documentation web server shared by you and your colleagues is a wonderful productivity tool. Most of us know simple HTML, and can whack up a web page as easily as writing plain text. But using Markdown is better. Read more
