Linux 7.3 Adds New "bpf_sock_read_xattr" Feature For systemd, BPF Programs
Merged earlier this year for Linux 7.1 was extended attributes on sockets support as a feature sought after by the likes of GNOME and systemd for helping with Varlink IPC usage and other purposes. A limitation though of the functionality has been no efficient means for a BPF program to read those user extended attribute labels back. But with Linux 7.3 that's being addressed with the new bpf_sock_read_xattr() kernel function...
IOmap Improvement For Linux 7.3 Takes EXT4 & XFS Performance Further
As part of the VFS pull requests now merged to the Linux 7.3 development kernel was an improvement to the IOmap framework used by various file-systems for mapping logical file byte offsets in memory to their physical locations on storage. With the now-merged code, this modern block mapping framework is allowing better performance at least for the EXT4 file-system...

The CachyOS Performance vs. Other Linux Operating Systems On A $46k USD Workstation
Recently I looked at the performance of Ubuntu 26.04 LTS vs. Windows 11 on the Intel Xeon 678X running within the HP Z4 G6i workstation. Linux performed admirably as one would expect. With this Intel Xeon Granite Rapids WS workstation from HP though commanding a retail price more than $46,000 USD, you likely want nothing but the utmost performance out of it. So for those looking to maximize the OS performance, here are some numbers from the HP Z4 G6i workstation when running not only Ubuntu 26.04 LTS but also Fedora Workstation 44, AlmaLinux, and the performance-optimized CachyOS.
Rust For Linux 7.3 Begins Seeing Fixes To Prepare For Rust's GCC Backend
In addition to the POWER/PowerPC code adding Rust kernel support, the main set of Rust programming language updates for the Linux 7.3 kernel have now been submitted. Most notable are early fixes toward eventually allowing the experimental Rust GCC back-end to be used as an alternative to the official rustc compiler with LLVM code generation...
Linux 7.3 Corrects Faulty Behavior Of FAT File-System Driver For Filenames Too Fat
It's not too often that the Linux FAT driver for FAT12/FAT16/FAT32 format support receives updates worth mentioning. For Linux 7.3 there is one patch though and it's due to the driver until now lacking an upper-bounds check on the length of the filename, which could lead to some unexpected situations with extremely long filenames...
Fedora x86-64-v3 Optimized Packages Pushed Back To At Least Fedora 46
There was a proposal under discussion the past few months on building x86-64-v3 packages for Fedora 45 while retaining x86-64-v1 packages. The hope was building the Fedora packages with x86-64-v3 where AVX/AVX2, FMA, BMI2, and other newer ISA features can be assumed in the name of better performance. Unfortunately, the x86-64-v3 plans are now delayed but may be reconsidered next year with Fedora 46...

Linux 7.3 To Land Initial Code Improving vRAM Management, More Improvements Coming
Earlier this year Natalie Vock of Valve's Linux graphics team laid out some patches for improving the Linux gaming experience for systems with limited vRAM. The kernel work for improving that video memory management is set to be introduced in the Linux 7.3 kernel. While that's a celebration on its own, Vock is pursuing more improvements still for bettering the Linux GPU driver video memory management behavior...

ARCTIC Fan Controller: The Best Fan Controller For Linux Desktops, Less Than $10 USD
Back in March were patches posted by ARCTIC Cooling for an ARCTIC fan controller driver for Linux. Typically we aren't used to seeing desktop/enthusiast focused vendors providing such Linux drivers for peripherals directly but the sad fact is most often it's left up to the open-source community to reverse engineer and create such drivers for Linux. Making it all the more surprising besides it coming from ARCTIC Cooling directly was that at the time they didn't even have a fan controller product with USB interface. Well, now it's launched and in turn is a great USB fan controller for Linux systems and retails for just $9 USD.

A revised patch then put it as much as a 43% improvement for this AVX-512 optimized xor_gen() function. The code hasn't yet been merged to mainline but an updated version of it is now available...
Linux 7.3 binfmt_misc To Allow BPF Programs To Dynamically Choose Execution Environments
The Linux kernel's binfmt_misc functionality allows non-native/custom files to be run directly such as for Windows EXE files to be handled by Wine or JAR files to be handled by the Java runtime. For the upcoming Linux 7.3 merge window, the miscellaneous binary formats support is being extended so a binary type can be matched programmatically and the interpreter determined on a per-exec basis. BPF programs can also then be attached to dynamically choosing an execution environment on a per-binary basis...

Linux 7.1, Linux 7.2 Performance On The Intel Xeon 600 Series
With Linux 7.2 expected for its stable release this weekend, today's testing has some additional testing of the Linux 7.2 Git kernel as well as Linux 7.1 stable compared to Linux 7.0 as used by default on Ubuntu 26.04 LTS. Phoronix testing previously conducted of Linux 7.2 have shown benefits for Intel Arc B390 Xe3 in some configurations, faster poll performance on AMD Ryzen Threadripper and other hardware, and some nice I/O performance gains on AMD EPYC Turin. Today's kernel benchmarks are with the Intel Xeon 678X Granite Rapids WS currently in the lab as part of the HP Z4 G6i workstation testing.

Patches Posted For Fixing The Linux DRM Scheduler's Fair Policy
Ahead of the Linux 7.2 kernel release expected out on Sunday, the Direct Rendering Manager (DRM) subsystem was forced to revert their "fair" scheduler policy default new for this kernel. Due to a last minute user-reported regression, FIFO returns as the default DRM scheduler policy for Linux 7.2. But patches are now available for addressing that regression and thus hopefully for Linux 7.3 there will be the fair scheduler becoming the default...
