Here Is Why The Linux 4.2 Kernel Is Messing Up On Some Ubuntu Systems

The Linux 4.2 kernel that's currently under development ships many new features, but as I've been writing about for a while and tweeting, the 4.2 Git code hasn't been booting on many systems in my test lab for over one week. Various Phoronix readers have also been able to reproduce these different kernel panics that happen almost immediately into the boot process. Here's the root problem affecting Linux 4.2 on my daily Linux benchmarking systems...

A Week With GNOME As My Linux Desktop: What They Get Right & Wrong

When I sent the Fedora 22 KDE Review off to Michael I did it with a bit of a bad taste in my mouth. It wasn't because I didn't like KDE, or hadn't been enjoying Fedora, far from it. In fact, I started to transition my T450s over to Arch Linux but quickly decided against that, as I enjoyed the level of convenience that Fedora brings to me for many things.

The Many New Features Of The Linux 4.2 Kernel

If all goes according to plan, the Linux 4.2 kernel merge window will close this afternoon followed by the immediate release of the Linux 4.2-rc1 test version. With all major pull requests having already been submitted for Linux 4.2, here's an overview of the exciting new features and changed functionality to look forward to with this kernel version to officially debut later this summer!

6-Way File-System Comparison On The Linux 4.1 Kernel

With the Linux 4.1 kernel having recently been released, I decided to conduct a fresh round of file-system comparisons on this new kernel using a solid-state drive. The file-systems tested in this article were the in-tree EXT4, Btrfs, XFS, F2FS, ReiserFS, and NILFS2 file-systems while a follow-up article will take a look at the out-of-tree contenders like Reiser4 and ZFS atop Linux 4.1.

How KDE VDG Is Trying To Make Open-Source Software Beautiful

One of the most often voiced complaints about Open Source Software is that it tends to be "ugly" or otherwise aesthetically uninspired. A few years ago a few people in the KDE camp came together and created, what they hoped, would be a solution to that problem: The KDE Visual Design Group.

Linux 4.1 Offers Potentially Dazzling Performance

Besides presenting a lot of new kernel features and functionality, the upcoming Linux 4.1 kernel release is potentially very exciting if you're an owner of certain classes of Intel hardware that offer better performance under this new kernel -- and in some cases, better battery life. Here's some tests from yet another system I found exhibiting some promising results from this new 2015 summer kernel version.

Phoronix Test Suite 5.8 Furthers Phoromatic For Enterprise Benchmarking

Phoronix Test Suite 5.8 was released today as the latest quarterly update to Phoronix Media's open-source, cross-platform benchmarking and automated testing software. Beyond offering a significant number of new features, the Phoronix Test Suite 5.8 release commemorates seven years since the release of Phoronix Test Suite 1.0 and eleven years since the start of Phoronix.com in what's evolved to become the largest Linux hardware destination on the Internet.

Opening The Gates To Our Daily Open-Source Linux Benchmark Results

For a few months now I've been talking about the LinuxBenchmarking.com initiative to provide daily benchmark results of the latest development Git/SVN code for various open-source projects in a fully-automated manner... Among the projects being tracked have been the Linux kernel, GCC, LLVM Clang, etc. There's dozens of systems at Phoronix Media in "the basement server room" doing nothing but running these upstream benchmarks day in and day out. The data flow is now open at LinuxBenchmarking.com.

Linux 4.0 SSD EXT4 / Btrfs / XFS / F2FS Benchmarks

A few days ago I ran some fresh hard drive file-system benchmarks on Linux 4.0 and today those results are being complemented by the solid-state drive results. Tested on the SSD were the popular EXT4, Btrfs, XFS, and F2FS file-systems.

Linux 4.0 Hard Drive Comparison With Six File-Systems

It's been a while since last running any Linux file-system tests on a hard drive considering all of the test systems around here are using solid-state storage and only a few systems commissioned in the Linux benchmarking test farm are using hard drives, but with Linux 4.0 around the corner, here's a six-way file-system comparison on Linux 4.0 with a HDD using EXT4, Btrfs, XFS, and even NTFS, NILFS2, and ReiserFS.

More Linux Benchmarks Of The AMD FX-8370E / FX-8370 / FX-9590

In adding some extra tests besides what was shared in our large Linux review of the new AMD FX CPUs from earlier in the week, that included a fairly big comparison of Intel and AMD CPUs, here's some more Linux test results for just the FX-8370E, FX-8370, and FX-9590 processors.

GCC 5.0 Outruns LLVM 3.5 Compiler By A Bit On Core-AVX2

In anticipation of the LLVM 3.5 release that brings a number of new compiler features -- including possible performance improvements from our benchmarking done earlier today -- here's some benchmarks comparing LLVM Clang 3.5 RC3 to a recent SVN snapshot of the GCC 5.0 compiler that's presently under development.

LLVM Clang 3.5 Brings Some Compiler Performance Improvements

If all goes well, LLVM 3.5 will be released today. While we have already delivered some LLVM/Clang benchmarks of the 3.5 SVN code, over the days ahead we will be delivering more benchmarks of the updated compiler stack -- including looking at its performance against the in-development GCC 5.0. For getting this latest series of compiler benchmarking at Phoronix started, here's some fresh numbers of LLVM Clang 3.4 compared to a recent release candidate of LLVM Clang 3.5.

Testing For The Latest Linux Kernel Power Regression

As I wrote about yesterday, there appears to be a new Linux kernel power regression that's yet to be solved by the latest Linux 3.17 code. The issue was originally tracked down to being a regression introduced during the Linux 3.15 stable cycle that disabled frame-buffer compression support by default for the Intel DRM graphics driver, but the impact it's had on the system power draw is much greater than what was anticipated by the Intel developers. A separate Intel employee is also reporting increased power draw, so I decided to run some tests on a few local systems to see what I'm encountering in the power consumption primarily between Linux 3.15 and 3.16.
