Arm Has Been Working To Boost The Chrome/Chromium Browser Performance

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.

webOS Open Source Edition 2.1 Released For Continuing The Palm/HP/LG Linux Distro

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.

Wine Patches Coming To Allow UMIP Emulation - Works Around Issues For Ryzen 3000

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.

Linux 5.5 To Finally Expose NVMe Drive Temperatures Via HWMON

Linux for years has supported monitoring NVMe drive temperatures when installing the nvme user-space utility and run as root, etc. But now finally with Linux 5.5 the kernel is supporting NVMe drive temperature reporting through the hardware monitoring "HWMON" infrastructure alongside other hardware sensors.

PHP 7.4 Performance Benchmarks Show A Nice Improvement - But PHP 8.0-dev Is Running Even Faster

PHP 7.4 is due to be released next week as the annual major iteration to PHP7. Like we have seen through the PHP7 releases, while new features continue to be tacked on for this popular web-based programming language the performance has continued evolving. Here are the latest benchmarks of PHP 5.6 through PHP 7.4 while also looking at the PHP 8.0-dev performance that is in development on Git master.

NVIDIA DP MST Audio To Begin Working With The Linux 5.5 Kernel

While the official NVIDIA Linux driver has worked well with DisplayPort Multi-Stream Transport (DP MST) setups for years now for driving large displays, audio hasn't worked under Linux for NVIDIA's driver in this combination. But with the upcoming Linux 5.5 cycle that will be addressed.

Mesa 19.3.0 Not Expected Until December - RC4 Released With ACO Fixes

Mesa 19.3 had been expected for release next week per their original release calendar, but as we are used to seeing for these quarterly feature releases, at least one if not more weekly release candidates tend to be needed for ironing out bugs. As such, Mesa 19.3.0 is now solidly looking like at least an early December release while Mesa 19.3-RC4 shipped on Wednesday.

JCC Erratum Impact On Skylake Xeon Scalable Plus The Patched Assembler

Last week ago we provided a number of benchmarks looking at the performance impact from Intel's Jump Conditional Code (JCC) Erratum that required a CPU microcode update to mitigate but that comes with a performance hit. At least Intel has pending GNU Assembler patches to help offset that performance hit. In time for last week's articles I didn't have a chance to perform Skylake Xeon Scalable (1st Gen) benchmarks but now here are some metrics alongside Cascade Lake.

Oracle Solaris 11.4 SRU15 Has A Number Of Package Updates

While there is no sign of Solaris 11.5 or Solaris.Next (last year was a road-map pointing to Solaris 11.Next in H2'19 or H1'20 that has since been removed), Oracle does continue putting out more updates to the Solaris 11.4 series.

Intel Haswell To Ice Lake Laptop Performance Benchmarks On Ubuntu 19.10

With the many Intel Ice Lake Linux benchmarks we began publishing over the past month since picking up a Dell XPS with Core i7-1065G7, there have been many benchmarks compared to the likes of the Core i7 Whiskey Lake and Kaby Lake processors. For those curious how the performance stacks up going further back, here are some Ubuntu 19.10 laptop benchmarks putting it up against the likes of Core i7 Haswell and Broadwell processors.

Linux's Crypto API Is Adopting Some Aspects Of Zinc, Opening Door To Mainline WireGuard

Mainlining of the WireGuard secure VPN tunnel was being held up by its use of the new "Zinc" crypto API developed in conjunction with this network tech. But with obstacles in getting Zinc merged, WireGuard was going to be resorting to targeting the existing kernel crypto interfaces. Instead, however, it turns out the upstream Linux crypto developers were interested and willing to incorporate some elements of Zinc into the existing kernel crypto implementation.

Intel's Graphics Driver DoS Fix Last Week Has Hurt Power Consumption

While the patches overnight about "substantial" improvement in power usage for Intel graphics on Linux were exciting on first look, it's less so now as it turns out last week's graphics driver security fixes is what regressed the Intel graphics power-savings.

Intel's oneAPI / DPC++ / SYCL Will Run Atop NVIDIA GPUs With Open-Source Layer

With yesterday's much anticipated Intel oneAPI beta being built around open-source standards like SYCL, the "cross-device" support can at least in theory extend beyond just Intel platforms. Codeplay is already showing that's possible with a to-be-open-source layer that will allow oneAPI and SYCL / Data Parallel C++ to run atop NVIDIA GPUs via CUDA.

Intel To Drop Very Old Drivers/BIOS From Their Site, But The Linux Impact To Be Minimal

Making waves today is that Intel will be removing very old BIOS and driver downloads from their site on or after 22 November. Though these software downloads for the products in question are around ~20 years old so the real-world impact should be small plus with Linux drivers being in the mainline kernel, all you'd really be losing out on are BIOS updates that themselves haven't seen updates in years.
