It's Been A Quiet Year-End For BUS1, The Proposed In-Kernel IPC For Linux

Filed under
Linux

With the Linux 4.10 kernel merge window expected to open this weekend, I was digging around to see whether there was anything new on the BUS1 front and whether we might see it for the next kernel cycle.

While I have yet to see any official communication from the BUS1 developers, it doesn't look like it's happening for BUS1. In fact, it's been a rather quiet past few weeks for these developers working on this in-kernel IPC mechanism to succeed the never-merged KDBUS.

Viewing Linux Logs from the Command Line

Filed under
Linux
HowTos

At some point in your career as a Linux administrator, you are going to have to view log files. After all, they are there for one very important reason...to help you troubleshoot an issue. In fact, every seasoned administrator will immediately tell you that the first thing to be done, when a problem arises, is to view the logs.

And there are plenty of logs to be found: logs for the system, logs for the kernel, for package managers, for Xorg, for the boot process, for Apache, for MySQL… For nearly anything you can think of, there is a log file.

At Long Last, Linux Gets Dynamic Tracing

Filed under
Linux

When the Linux kernel version 4.9 will be released next week, it will come with the last pieces needed to offer to some long-awaited dynamic thread-tracing capabilities.

As the keepers of monitoring and debugging software start using these new kernel calls, some of which have been added to the Linux kernel over the last two years, they will be able to offer much more nuanced, and easier to deploy, system performance tools, noted Brendan Gregg, a Netflix performance systems engineer and author of DTrace Tools, in a presentation at the USENIX LISA 2016 conference, taking place this week in Boston.

Three serious Linux kernel security holes patched

Linux
Security

The good news is developers are looking very closely at Linux's core code for possible security holes. The bad news is they're finding them.

At least the best news is that they're fixing them as soon as they're uncovered.

The latest three kernel vulnerabilities are designated CVE-2016-8655, CVE-2016-6480, and CVE-2016-6828. Of these, CVE-2016-8655 is the worst of the bunch. It enables local users, which can include remote users with virtual and cloud-based Linux instances, to crash the system or run arbitrary code as root.

Conexant voice board lets you summon Alexa from a Raspberry Pi

Filed under
Linux

Conexant and Amazon have launched an Alexa Voice Service development kit for the Raspberry Pi 3. The kit includes a Conexant AudioSmart CX20921 voice board.

Since Amazon opened up access to its Alexa Voice Service (AVS) agent inside the Amazon Echo smart speaker/IoT hub, including an open source port to the Raspberry Pi, several projects have emerged for creating Echo-like devices built around the RPi. For example, earlier this year, a Novaspirit Tech hack along these lines was promoted by the Raspberry Pi blog. Now Conexant Systems and Amazon have teamed up on a higher end “AudioSmart 2-mic Development Kit” for the RPi that’s designed specifically for voice-controlled smart home IoT functionality.

  • Vulkan/OpenGL Performance With AMDGPU-PRO 16.50 vs. Mesa 13.1-dev

    This morning's AMDGPU-PRO 16.50 preview included some 16.40 vs. 16.50 hybrid driver benchmarks, but for those wondering how 16.50 compares to Mesa 13.1-dev for RadeonSI OpenGL and RADV Vulkan, here are some preliminary tests for the two current Vulkan AAA Linux games.

  • Here Is The AMDGPU-PRO 16.50 Download Link

    AMD ran into a snag getting out the updated proprietary hybrid Linux driver stack this morning, but it's now available for download from AMD.

    This page has the 16.50 Linux x86/x86_64 driver available for download.

  • It Looks Like AMDGPU DC (DAL) Will Not Be Accepted In The Linux Kernel

    While AMD developers have been working to improve their "DAL" (now known as "DC") display code for the better part of the past year and this code is needed for new hardware support as well as supporting HDMI/DP audio on existing AMDGPU-enabled hardware plus other features, it's still not going to be accepted to the mainline kernel in its current form.
