While iXsystems has been known as one of the leading FreeBSD-focused vendors with their various BSD-powered storage devices and servers as well as contributing significantly to upstream FreeBSD in addition to their former work on TrueOS/PC-BSD, they are now developing a new platform called TrueNAS SCALE that is based on Linux...
Linux power management / ACPI maintainer Rafael Wysocki of Intel has sent in the usual big batch of PM/ACPI changes for the next version of the kernel, Linux 5.8...
With the PHP 8.0 schedule putting the first alpha release for the middle of June, I've been trying out its latest Git state in recent days for looking at its performance as well as when enabling its brand new JIT (Just In Time) compiler support that is new to PHP8. The results are quite compelling and here are metrics going back to the days of PHP 5.4 for comparison.
The Direct Rendering Manager (DRM) updates have been sent in as the open-source graphics/display driver updates for Linux 5.8 amounting to around 42k lines of new code and some 21k lines of code being removed...
During the month of May on Phoronix were 252 original news articles and 20 featured Linux hardware reviews / benchmark specials written by your's truly. This included some surprising announcements from Microsoft, Linux 5.7 getting wrapped up and Linux 5.8 features being firmed up ahead of the now-open merge window, AMD Renoir mobile being a big success, and other milestones for open-source software...
SUSE's David Sterba was quite punctual in getting all of the Btrfs file-system updates submitted quickly for the newly-opened Linux 5.8 kernel merge window...
Valve's May 2020 numbers show another uptick for Steam Linux gaming usage, pointing towards the Linux marketshare continuing to increase with the overall Steam user-base in this coronavirus period leading to record usage with the extra time spent by gamers at home...
As part of the initial set of changes merged today for Linux 5.8 was the x86/mm material that included the controversial feature of opt-in flushing of the L1 data cache on context switching. Linus Torvalds ended up deciding to revert this functionality as for now at least he views it as crazy...
One of the use-cases for this new "initrdmem" option in Linux 5.8 can be for storing an initial ramdisk (initrd) on a motherboard flash chip in the space available after stripping out Intel's Management Engine (ME) code...
A few weeks back I began delivering Ryzen 7 4700U Linux laptop benchmarks for this 8-core Zen 2 mobile CPU with Vega graphics. The results have been very good and the support is in good shape with the latest Linux kernel, but many have been wondering about the Ryzen 5 4500U. The Ryzen 5 4500U is beginning to appear in several $500~600 USD laptops and offers six cores. Here are benchmarks and initial impressions with the Lenovo Flex 5 that features a 14-inch 1080p display, 16GB dual channel memory, 256GB SSD, and the Ryzen 5 4500U all for just $599!
For those very concerned about CPU data sampling vulnerabilities, the Linux 5.8 kernel comes with the ability to flush the L1 data cache on each context switch. That's good for security, but will hurt the system performance with all the excess L1 cache flushing...
Linux Mint 20 is in the works as the re-base off this popular desktop Linux distribution that in turn is derived from the Ubuntu package set. With Linux Mint 20 they are re-basing to Ubuntu 20.04 LTS packages but with better measures to ensure Snap packages don't end up on user systems...
Newer Windows games/applications are making use of system call instructions from the application code without resorting to the WinAPI and that is breaking Wine emulation support. A Linux kernel patch is now being worked on for addressing this issue in the form of system call isolation based on memory areas while having a smaller performance hit than alternatives...
Google's Chrome/Chromium web browser is finally reaching the stage where having both the X11 support and Ozone abstraction layer for Wayland can be enabled concurrently in the same build...
At least for the workloads tested this round, when booting the new Intel Core i9 10900K "Comet Lake" processor with the software-controlled CPU security mitigations disabled, the overall performance was elevated by about 6% depending upon the workload. Here is a look at the out-of-the-box security mitigations for this new Intel desktop CPU against foregoing the default CPU security mitigations and running an unprotected configuration to see what the pre-Spectre performance looks like.
One of the interesting new happenings in the Direct Rendering Manager (DRM) driver space is a Generic USB Display stack including a USB gadget driver that together allow for some interesting generic USB display setups. This work was motivated by being able to turn a $5 Raspberry Pi Zero into a USB to HDMI display adapter...
KDE Plasma 5.19 is due for release very soon (9 June) but that hasn't kept KDE developers from already working on Plasma 5.20 and other components for this open-source desktop...
Valve developers have been working on Vulkan shader pre-caching with their latest Steam client betas to help in allowing Vulkan/SPIR-V shaders to compile ahead of time, letting them be pre-cached on disk to allow for quicker game load times and any stuttering for games that otherwise would be compiling the shaders on-demand during gameplay, especially under Steam Play...
One of the latest performance optimizations being pursued by Intel on the open-source Linux side is providing an AVX-512-optimized container for Golang usage...

Following the Xeon Gold 6250 vs. EPYC 7F32 benchmarks from earlier this month, here is a look at the latest x86_64 server CPUs we have our hands on with the EPYC 7F72 and Xeon Gold 6258R being benchmarked against a lineup of other competing AMD EPYC and Intel Xeon processors under the new Ubuntu 20.04 LTS.
The FSGSBASE Linux kernel patches that have the potential of helping performance going back to Intel Ivy Bridge era CPUs in select workloads have now hit their 13th revision to the series in the long-running effort to getting this support mainlined...
While we have been eager for Godot 4.0 as the open-source game engine update bringing big renderer improvements and initial Vulkan support, it also turns out there will be a new offering on the editor front.....
Assuming no last minute concerns, the Linux 5.7 kernel is set to debut as stable this weekend. Given all the weeks since the merge window and our many articles covering all the feature activity at that point (and not to be confused with our activity of new work being queued for the upcoming Linux 5.8 cycle), here is a look back at some of the top features of the Linux 5.7 kernel...
