One of the first follow-on requests from this morning's Razer Blade Stealth Linux testing was for on top of all the other data-sets shared in that article to also look at the RAM usage, battery power draw, and boot times for the different desktop options on Ubuntu 17.04. As the request came in from a Phoronix Premium supporter, I jumped on that and here are some of those numbers.
Earlier this year Razer co-founder and CEO Min-Liang Tan announced that Razer is planning better laptop support on Linux. He noted that more customers are requesting Linux support and they formed a goal of figuring out how to make "the best notebook in the world that supports Linux." Razer doesn't have any Linux laptop announcement to make yet, but for seeing the current state of affairs, they sent over the Razer Stealth laptop so we could put it through our Linux testing paces at Phoronix. Here is a look at the Razer Stealth ultrabook on Linux as well as a variety of interesting performance metrics, including some power metrics compared to Windows.
One of the unique test requests coming in as part of our Threadripper on Linux testing is to see how well the LLVMpipe and OpenSWR CPU-based OpenGL implementations within Mesa perform for this 16 core / 32 thread single-socket processor. Here are those results...

While we routinely run various Linux distribution / operating system comparisons at Phoronix, they tend to be done on desktop class hardware and the occasional servers. This is our look at the most interesting enterprise-focused Linux distribution comparison to date as we see how Intel's Xeon Scalable platform compares on different GNU/Linux distributions when using the Tyan GT24E-B7106 paired with two Dual Xeon Gold 6138 processors. The tested configuration has 96GB of DDR4-2666 memory and 40 cores / 80 threads to see how different modern Linux distributions are affected with the latest-generation Xeon platform.

Last week I was able to finally get my hands on a Threadripper 1950X system thanks to AMD for being able to deliver some Linux tests from this high-end desktop platform. The Threadripper 1950X as a reminder is a 16-core processor with 32 threads via SMT, 3.4GHz base frequency, 4.0GHz boost frequency, quad-channel DDR4 support, and support for 64 PCI-E lanes. Threadripper sits between the Ryzen 7 desktop processors and the AMD EPYC server/workstation processors, which are still soon to be tested at Phoronix. The Ryzen Threadripper 1950X will set you back $999 USD, but compared to the Core i9 7900X at the same price, has six more cores / 12 threads and a slightly higher base clock frequency of 3.4GHz vs. 3.3GHz but a lower boost frequency of 4.0GHz vs. 4.3GHz.
The Fedora Engineering and Steering Committee has been working to firm up the release schedule for the Fedora 28 Linux operating system update due out in Q2'2018...
Last month in LLVM there was new Sandy Bridge scheduler information to improve the instruction scheduling and other hardware detail changes so LLVM can generate more efficient code for those older CPUs. At that time we learned Intel developers were also planning improvements too for LLVM with newer Haswell / Broadwell / Skylake / Skylake-X CPUs. Improvements have now landed for Haswell...
While we've seen the Radeon Linux OpenGL driver get competitive to the Windows Radeon OpenGL driver and the NVIDIA Windows/Linux OpenGL binary drivers have long been on a level playing field, how's the Intel HD Graphics performance? Here are some quick and fresh benchmarks this weekend.
While there has been VirGL as one of the options for allowing 3D/OpenGL acceleration of Linux guests within QEMU/KVM virtual machines to allow the calls to be directed to the host system's OpenGL driver, that support hasn't been available when Windows is running as QEMU/KVM guest. That is changing though thanks in large part to this year's Google Summer of Code...
Following the news this week that RadeonSI may switch to NIR completely in the future, in the forums a number of questions were raised about why the Linux graphics drivers are using multiple forms of intermediate representation and whether this would still make RadeonSI a Gallium3D driver if it doesn't default to TGSI...
With testing out a Tyan 1U server featuring dual Intel Xeon Gold 6138 CPUs, one of the uncommon test requests we have received but understandable given our audience is curiosity about the performance of OpenGL software rendering on this 40 core / 80 thread Xeon Scalable server when making use of Mesa's LLVMpipe software rasterizer and the newer OpenSWR driver from Intel.
This week Purism announced their plans for the Librem 5 smart-phone as a GNU/Linux smartphone that is privacy-respecting, as open as possible, and costs $599 USD. The company believes they can have the phone ready for release by early 2019 if they raise $1.5 million USD over the next two months. In just about three days they have raised nearly $100,000, but it's not clear if the pacing will continue to reach the milestone in time...
