At this point Linus is appearing relieved that Linux 5.10 will be in good shape for shipping on time and without any major concerns...

With this month's release of Chrome 87 having more performance improvements while Firefox 83 debuted with its "Warp" JavaScript improvements, it's a good time for some fresh Linux web browser benchmarks of these two main options. Plus with Firefox 84 to begin enabling WebRender by default in some Linux configurations, there is also a fresh run of Firefox with WebRender enabled.

Earlier this month we covered the news of Xilinx is looking to upstream their open-source "AI Engine" driver to the Linux kernel. This comes as Xilinx and AMD are working on Radeon Open eCosystem (ROCm) support for their FPGAs with AMD being in the process of acquiring the FPGA giant. Now more open-source code is looking to be included in the Linux kernel tree...

While consumer GPUs are reaching market with AV1 decode acceleration, there still is the matter of the various media APIs and multimedia software making use of it. In cases where that is missing or the user doesn't yet have a supported Tiger Lake / Ampere / RDNA2 GPU, the dav1d decoder remains the fastest open-source CPU-based AV1 decoder. Similarly, SVT-AV1 remains the fastest CPU-based AV1 encoder available...

One area not talked about much for Intel's latest Tiger Lake processors are hardened CPU security mitigations against the various speculative execution vulnerabilities to date. What's peculiar about Tiger Lake though is now if disabling the configurable mitigations it can actually result in worse performance than the default mitigated state. At least that's what we are seeing so far with the Core i7 1165G7 on Ubuntu 20.10 Linux is the opposite of what we have been seeing on prior generations of hardware.

Intel's Linux graphics driver developers have submitted their final batch of feature changes targeting the Linux 5.11 kernel...

FUSE is well known to longtime Linux users for allowing file-systems to be implemented in user-space for where a Linux kernel port isn't feasible for portability or licensing restrictions, among other factors. There is also CUSE for character devices in user-space. Now being based on FUSE, there is "MUSE" being worked on for MTD in user-space...

Just some quick, friendly holiday reminders...

PHP 8.0 is scheduled for release tomorrow on the US Thanksgiving day. PHP 8.0 brings with it many new language features on top of the opt-in JIT compiler support. Here is a look at some of the PHP 8.0 changes along with a quick look at the near final performance of PHP 8.0 on an AMD EPYC Linux server...

Last week a new vulnerability was made public for IBM POWER9 processors resulting in a mitigation of the processor's L1 data cache needing to be flushed between privilege boundaries. Due to the possibility of local users being able to obtain data from the L1 cache improperly when this CVE is paired with other side channels, the Linux kernel for POWER9 hardware is flushing the L1d on entering the kernel and on user accesses. Here are some preliminary benchmarks looking at how this security change impacts the overall system performance.

Thanks to work by AMD and SUSE engineers, the Linux kernel could soon be seeing frequency invariance support for EPYC 7002 "Rome" processors for yielding greater performance and power efficiency...

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...

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.
