Phoronix

With the Jump Conditional Code (JCC) Erratum that was made public earlier this month and ushered in new Intel microcode to mitigate this Skylake to Cascade Lake design defect, compiler/toolchain patches have been in the works to help offset the performance cost incurred from the updated microcode. Besides the GNU Assembler work we've talked about several times since JCC came to light, the LLVM folks have also been reviewing their comparable changes...

Over the years at Phoronix we have easily close to forty if not more Rosewill 2U and 4U sever cases... Rosewill's server cases have been among the best value enclosures when not needing any extra features like hot-swap bays, etc. For under $100 USD, their Rosewill 4U cases have been a favorite due to the cost yet good quality, fan filter, etc. A new revision out this summer is the Rosewill RSV-4310 that appears to have replaced the likes of the RSV-R4000. The RSV-4310 4U enclosure does bring some nice minor updates to the base enclosure we've come to know and appreciate though is more costly.

David Sterba sent in his pull request early of the Btrfs file-system changes that are ready for merging into the Linux 5.5 merge window next week...

We have done a lot of benchmarks on Intel/AMD x86_64 for Ubuntu 19.10 for seeing how its performance is looking, but what about IBM POWER9 with the likes of the libre Raptor Blackbird? Here are some Ubuntu 19.04 vs. 19.10 POWER benchmarks I recently carried out...

A few weeks back I wrote about NVIDIA's Nitin Gupta working on proactive memory compaction for the Linux kernel to more proactively compact memory rather than doing so on-demand when it can lead to high latencies for applications needing lots of huge-pages...

While it's taking painfully long to get X.Org Server 1.21 organized for release, at least in the interim there continues to be new xorg-server 1.20 point releases that back-port many of the prominent fixes...

While the Linux 5.5 cycle begins next week, looking ahead to early next year when the Linux 5.6 cycle will begin, there is expected to be another power management improvement coming for AMD Radeon graphics cards...

A few days ago 7 Days to Die saw a performance boost on Mesa Git from its "glthread" threading implementation while now a number of game emulators have seen similar whitelisting...

Ending out the week is an exciting development in the Intel open-source graphics driver space... Shared Virtual Memory (SVM) support! This is another step towards their upcoming discrete Xe GPUs and ultimately their exciting oneAPI conquest...

The inaugural release of Glimpse is now available, the fork born out of calls for renaming The GIMP project to something not considered offensive...

It's been almost two months since last looking at the RADV ACO performance for this shader compiler back-end alternative to the AMDGPU LLVM code. ACO is making its debut in the upcoming Mesa 19.3 release while since the last round of testing have been more optimizations and fixes as well as getting the Navi/GFX10 support in place. In this article are some fresh benchmarks of the Vulkan RADV ACO support for not only Polaris and Vega but also the Radeon RX 5700 Navi graphics cards.

The Linux 5.4 kernel is to be released on Sunday and that will in turn kick-off the Linux 5.5 merge window. Here is a look at some of the changes on the table for what will in turn be the first major stable kernel release of 2020...

It looks like a big new systemd release will be out in time for Christmas...

Building off the NVIDIA 440 stable Linux driver release from earlier this month, the NVIDIA 440.36 Linux driver is out today as a small update...

With the big PHP 7.4.0 release due out next week, yesterday we published our PHP 7.4.0 benchmarks using the near-final build for this annual update to PHP. Those benchmarks compared previous releases as far back as PHP 5.6. But out of curiosity after that article I went to do some benchmarks going back to PHP 5.3 through PHP 7.4 and PHP 8.0-dev...

Arm engineers have been working to speed-up the open-source Chromium web browser on 64-bit ARM (AArch64) and ultimately to flow back into Google's Chrome releases. Their focus has been around Windows-on-Arm with the growing number of Windows Arm laptops coming to market, but the Chromium optimizations also benefit the browser on Linux too...

Released at the end of October to little fanfare was webOS Open Source Edition 2.0, the open-source Linux OS currently in development by LG for use on their Smart TVs and other digital products. With webOS Open Source Edition 2.0, they began setting their sights on automobiles and other potential use-cases. That was then extended by this week's release of webOS OSE 2.1...

Universal Bandwidth Compression is now enabled for the open-source "TURNIP" Mesa Vulkan driver...

Mesa 19.2.5 was just released earlier this week but now v19.2.6 has already been released due to the previous point release breaking IBM POWER builds...

Coming up this weekend with the Linux 5.4 kernel is emulation/spoofing of the SGDT/SIDT/SMSW instructions around UMIP for allowing newer 64-bit Windows games to run on Wine and Steam Play (Proton). With newer CPUs like the AMD Ryzen 3000 series that support UMIP, these instructions are not allowed to run in user-space with Wine due to UMIP. So while the first stable kernel release is about to land with this support, some Wine-based emulation not contingent on the kernel patches is also in the works...
