Given the recent Intel presentation alleging AMD Ryzen laptop performance being worse on battery relative to the AC vs. battery performance seen with Intel EVO notebooks featuring Tiger Lake processors, I ran a mini comparison on my side to see whether there is any merit to Intel's information when testing under Ubuntu Linux.
Earlier this year we mentioned Greg Kroah-Hartman working on a new READFILE system call. The goal of this new syscall is for reading small and medium files more efficiently by having one call to read a file straight into a buffer without having to use the separate open/read/close system calls. It's looking like that system call is back on the table and could be mainlined now that there's a possible user...
LibreOffice 7.1 was branched this weekend that also marked the hard feature freeze for this next half-year update to this open-source office suite. LibreOffice 7.1 Beta has now shipped ahead of next month's release candidate and the additional test releases in January before going gold in early February...

WireGuard's adoption continues growing with it recently having the accomplishments of being back-ported to Oracle's Unbreakable Enterprise Kernel, coming to Android 12, upstreamed into OpenBSD, and other accomplishments this year. The WireGuard developers have now also updated their port of this secure VPN tunnel technology for Micrsoft Windows...
Longtime open-source developer Mike Blumenkrantz who has been an Enlightenment developer for many years and was working for Samsung's Open-Source Group prior to its demise jumped into the open-source Linux graphics world this year. While being unemployed he began hacking on the Zink Gallium3D code that allows generic OpenGL acceleration over the Vulkan API. He quickly got the code to the point of OpenGL 4.6 support and quite compelling performance compared to where Zink was at earlier this year. Now it turns out he will continue with his Linux graphics adventures thanks to funding from Valve...
While in 2021 we might begin to see PipeWire replacing PulseAudio by default at least on bleeding-edge distributions like Fedora, for now PulseAudio still is the dominant sound server used by desktop Linux distributions. Rolling out today is PulseAudio 14.0...
Last week we delivered AMD Radeon RX 6800 / RX 6800 XT Linux benchmarks and the performance was great both for Linux gaming as well as the OpenCL compute performance. But for as good as those Big Navi numbers were on the open-source Linux graphics driver stack, they are now even better.
Intel held a virtual event last week to basically plead their case that AMD Ryzen laptops are coming up short on battery-powered performance compared to their own offerings. It was all Windows focused, but at least given their emphasis now on battery performance gave me another opportunity to prod over the lackluster state of Intel DPTF support on Linux with it not being pleasant out-of-the-box and one of the few areas encumbered by blobs or lack of public documentation...
While NVIDIA has supported its own vendor-specific Vulkan ray-tracing extension on Windows and Linux since the GeForce RTX GPUs originally debuted, they are moving quick to support the Khronos ray-tracing extensions for Vulkan given the industry adoption and games coming to market likely opting for using the KHR version...
With Wine on an annual stable release cadence for shipping new stable feature releases generally at the beginning of each calendar year after a year's worth of bi-weekly development snapshots, Wine 6.0 is due for release around January...
Earlier this year Vulkan ray-tracing arrived in provisional form while with today's Vulkan 1.2.162 specification update this functionality has been promoted to stable and ready for broad industry support...
Red Hat for several years now has been working on PipeWire to overhaul audio/video stream management on Linux while being able to fill the duties currently managed by the likes of PulseAudio and JACK and being engineered with Wayland and Flatpak security in mind among other modern Linux technologies. With Fedora 34 next spring they may try to ship PipeWire by default in place of JACK, PulseAudio, and even legacy ALSA...
This New Year's Eve will mark one year since the announcement of the in-development Reiser5 file-system. While the outlook for getting Reiser5 upstreamed into the mainline kernel remains murky given the out-of-tree status of Reiser4, Edward Shishkin does continue advancing this latest Reiser file-system iteration...

For over one year the Flash-Friendly File-System (F2FS) has supported case-folding for optional case-insensitive file/folder support. The past number of years F2FS has also supported FSCRYPT-based file encryption. But now as we roll into 2021, support is finally seemingly ready for mainline in supporting casefolding with encryption enabled...
Out this weekend is Phoronix Test Suite 10.2-Harstad Milestone 1 as the first development snapshot of this next quarterly feature update to our cross-platform, open-source benchmarking software...
Within Intel's vast open-source software ecosystem and much of the attention being on oneAPI as their preferred programming model for developers these days and there being multiple different open-source Intel graphics compiler back-ends, one that is often forgotten about is the Intel C for Metal Compiler that on Friday saw a new release...
In addition to squaring away the Radeon RX 6000 series RDNA 2 support and promoting the Arcturus support for the new GPU found within the AMD MI100 accelerator, this month AMD open-source Linux driver developers have been devoting a fair amount of work towards power optimizations...
Google engineers have sent out their latest patches for allowing the mainline Linux kernel to be built with LLVM Clang link-time optimizations (LTO) for greater performance and possibly size benefits...
It's been seven years since the release of libX11 1.6.0 for this central X11 library while on Friday was replaced by the libX11 1.7 series. The release is primarily made up of fixes but leading to the version bump is a new API that allows for applications to recover from I/O error conditions rather than being forced to exit...
We should be getting near the end of the Wine 5.xx development releases with the timed Wine 6.0 release likely to come in early 2021, but for now Wine 5.22 is out with the latest feature work for running Windows programs and games on Linux and macOS...
For those curious about the hardware potential out of Apple's in-house M1 processor powering new Mac Book Pros and Mac Mini, for the past week we have been running benchmarks of this ARM-based processor and have a number of benchmarks to share today looking at how the performance compares to prior Intel-powered Macs along with the Rosetta 2.0 performance for running x86_64 binaries on ARMv8.
Xfce 4.16 had been aiming to release in October~November as part of their new timed release approach but that has now slipped into the December~January time-frame but today saw the availability of the second pre-release...

The fallout should be minimal and hopefully not impact any Phoronix readers, but as Mesa rolls into 2021 it is looking to drop support for loading DRI1 graphics drivers...
This summer Intel disabled frame-buffer compression for Gen12 Tiger Lake graphics. While FBC helps conserve memory bandwidth and can be beneficial to power-savings, under-run issues and related problems resorted Intel to disabling this common feature for Tiger Lake...
Earlier this year we reported on Linux kernel work for better handling Windows games/apps that make system call instructions that bypass the Windows API. Directly making the system calls without going through the WinAPI has become an increasingly common occurrence for modern Windows games, likely as part of their Digital Rights Management schemes. Syscall User Dispatch is now the latest take on that effort...
Announced during the summer was Intel's Maple Ridge controller in the form of the Intel JHL8540 / JHL8340 chips as their first discrete Thunderbolt / USB4 controllers. Linux support for the Intel Maple Ridge controller is now on the way...
While it was just two days ago that AMDVLK 2020.Q4.4 was released, AMD has made good on their word to provide punctual AMDVLK open-source Vulkan driver support for their new RDNA 2 "Big Navi" graphics cards and that has resulted in a new AMDVLK release...
