Going back four years ago Intel engineers worked out bus lock detection for the Linux kernel to benefit their processors able to detect bus locks and then notify the kernel, given the negative performance implications associated with bus locks. That Intel support was merged in Linux 5.13 back in 2021 while now AMD has their equivalent ready for mainlining in the Linux kernel...

It's been one year since Canonical desktop engineer Daniel van Vugt, who is known for his upstream GNOME contributions, touched his patch-set implementing dynamic deadline evasion support.

As a follow up to the article from a few weeks ago of Intel publishing the AVX10.2 specifications and posting GCC compiler patches for that next iteration of AVX10, the initial support was merged today into the GNU Compiler Collection...

The past few months have seen patches for updating the XZ (de)compression code within the Linux kernel that's been a lengthy process in part due to the XZ backdoor situation earlier this year and the reputable XZ developers in turn being busy cleaning up that mess. In any event it appears that the updated XZ code for the Linux kernel is now on track for mainlining come Linux 6.12...

Colors within the GTK toolkit have been represented to date using sRGB but developers have been working on supporting other color spaces like Display-P3 and BT.2100-PQ as they work to better support High Dynamic Range (HDR) displays on the Linux desktop...

Linus Torvalds released Linux 6.11-rc3 a few minutes ago as the latest weekly release candidate...

Motherboard vendors have begun releasing updated BIOS versions for Intel Core 13th/14th Gen motherboards that offer the new "0x129" CPU microcode that is intended to address the Raptor Lake stability issues that have been causing instability problems and crashing errors for a growing number of Intel Core 13th/14th Gen processors. Intel reported in their (Windows) testing that the 0x129 CPU microcode should offer negligible performance impact but I was curious to run my benchmarks under Linux of this new CPU microcode.

Last week I wrote about a tiny Linux patch yielding up to 32% faster performance and up to 18% less energy for Emerald Rapids CPUs. That patch is an adjustment to the Intel P-State driver's Energy Performance Preference (EPP) value for that Intel Xeon Scalable family. Today that patch was merged for the Linux 6.11 kernel...

A number of Phoronix readers have been requesting a fresh re-test of the experimental Bcachefs file-system against other Linux file-systems on the newest kernel code. Your wish has been granted today with a fresh round of benchmarking across Bcachefs, Btrfs, EXT4, F2FS, and XFS using the Linux 6.11-rc2 kernel. This round of testing was carried out on the newly-released Solidigm D7-PS1010 PCIe 5.0 NVMe SSDs that offer very speedy performance for modern Linux desktops and servers.

Submitted for DRM-Next last week with intentions of getting it into the Linux 6.12 kernel was a new DRM "power saving policy" property. The intent was for this new monitor/display connector property to indicate whether power saving features should be used that could compromise the experience intended by the desktop compositor. But one week later this property is now set to be removed as it's been deemed immature...

A Qualcomm engineer has posted the Linux kernel patches for adding the DeviceTree to support the Microsoft Surface Laptop 7 devices powered by the new Qualcomm Snapdragon X1 SoCs. This allows Linux to run on these new Snapdragon X1-powered Microsoft laptops but as with the other devices there are a number of support caveats that for most end-users will be a showstopper...

For those still running an AMD Ryzen 3000 series "Zen 2" desktop it really ought to be time to upgrade soon for better performance and power efficiency given the Zen 5 performance benchmarks thus far, but for those still planning to use the Ryzen 3000 series for some time, a quirk/workaround is on the way for enabling more of those older platforms to work with the AMD P-State Linux driver...

Following decisions like exploring -O3 package builds for Ubuntu Linux, another newly-announced change by Canonical I must applaud is their decision to commit to shipping the very latest upstream kernel code at release time...

With the new AMD Ryzen 9000 series processors the AGESA supports up to DDR5-8000 memory. With yesterday's testing of the AMD Ryzen 5 9600X and Ryzen 7 9700X review all of the tests were done at DDR5-6000 in matching with the Ryzen 7000 series and Intel Core 13th/14th Gen configurations. In this article today is an initial look at the DDR5-8000 performance with the AMD Ryzen 7 9700X while using Corsair Vengeance 2 x 16GB DDR5-8000 DIMMs (Corsair CMH32GX5M2X8000C36).

This could quite well be my simplest review in the past twenty years of Phoronix. The AMD Ryzen 9000 series starting with the Ryzen 5 9600X and Ryzen 7 9700X launching tomorrow are some truly great desktop processors. The generational uplift is very compelling, even in single-threaded Linux workloads shooting ahead of Intel's 14th Gen Core competition, across nearly 400 benchmarks these new Zen 5 desktop CPUs impress, and these new Zen 5 desktop processors are priced competitively. I was already loving the Ryzen 7000 series performance on Linux with its AVX-512 implementation and performing so well across hundreds of different Linux workloads but now with the AMD Ryzen 9000 series, AMD is hitting it out of the ball park. That paired with the issues Intel is currently experiencing for the Intel Core 13th/14th Gen CPUs and the ~400 benchmark results makes this a home run for AMD on the desktop side with only some minor Linux caveats.

Solidigm today is formally announcing the D7-PS1010 PCIe 5.0 NVMe SSDs for the data center. The new D7-PS1010 solid-state drives offer phenomenal performance for PCIe Gen 5 servers as I've enjoyed in testing out a few of these D7-PS1010 SSDs the past several weeks and their leading performance that should be especially appealing for modern AI and HPC servers.

Back in February of this year you may recall the interesting news that was announced on Phoronix that AMD Quietly Funded A Drop-In CUDA Implementation Built On ROCm: It's Now Open-Source. That open-source ZLUDA code for AMD GPUs has been available since AMD quit funding the developer earlier this year. But now the code has been retracted. It's not from NVIDIA legal challenges but rather AMD reversing course on allowing it to be open-source...

Following last month's NVIDIA 560 Linux driver beta release where the open GPU kernel modules are used by default with Turing GPUs and newer, the NVIDIA 560.31.02 Linux driver has debuted today in stable form for the R560 series...
