For those having Linux systems with multiple swap devices, such as for swap tiering or layered swap handling, a set of patches posted today for the Linux kernel are looking to improve the situation.

Following the recent GA of the AWS M9g series as the first instances powered by the new Graviton5 CPUs, I recently ran benchmarks looking at Graviton4 vs. Graviton5 CPU performance. There was very nice generational gains for the new AWS Graviton processors with the shift from Arm Neoverse-V2 to Neoverse-V3 cores and from DDR5-5600 to DDR5-8800 memory, among other improvements. For those wondering how the Graviton5 ARM server processors compare to AMD EPYC and Intel Xeon, here are some additional comparison data points from the Amazon EC2 cloud.

Alfonso Siciliano, who has been one of the FreeBSD developers leading the effort on adding a KDE-based desktop option to the FreeBSD installer, provided an update on recent work around adding integrating this desktop option.

GNOME developers working on GNOME OS have received funding from Germany's Prototype Fund to work on creating the GNOME OS "Developer Tool Suite" or also tentatively called their "Test Center" to help in testing experimental applications/libraries in a modern Linux computing world with systemd-sysext, Buildstream, and other newer tech.

Stemming from looking at a proposed Linux kernel patch to alter the Linux kernel's system call number handling, veteran Linux kernel developer Thomas Gleixner went down a rabbit hole of the kernel's system call entry handling to make a number of clean-ups and improvements to the code. That rework to the system call entry handling is now expected to land for the Linux 7.3 kernel cycle.

While the Raspberry Pi 5 is already over two and a half years old, one of the missing elements of its support from the mainline Linux kernel has been the IOMMU driver. We are now seeing Raspberry Pi's downstream IOMMU driver being adapted for mainline with hopes of getting it into the upstream kernel.

Cloud Hypervisor 53.0 is now available for this open-source, Rust-based VMM focused on cloud workloads and modern security needs. Originally started at Intel, Cloud Hypervisor continues seeing new development these days by Microsoft, Meta, Arm, and other organizations.

Linux 7.2-rc3 is now available for testing in working toward the stable Linux 7.2 kernel version coming up in August.

Similar to Linux 7.2 enabling Eswin SoC support by default in the RISC-V "defconfig" kernel build, UltraRISC RISC-V coverage is also now being enabled by default for RISC-V kernel builds in Linux 7.2.

The Harmonic Firmware Initiative "HFI" is trying to provide a generic, standardized power-on firmware experience for RISC-V boards. Akin to the x86 world with having immediate graphics card initialization to provide a display while the system is booting and also having a BIOS setup utility for system configuration, HFI is trying to do the same for the RISC-V world.

It wasn't on my bingo card for the week but merged to Git ahead of today's Linux 7.2-rc3 kernel release are a number of fixes for the SEGA Dreamcast drivers.

The staging driver fixes that were sent out this week ahead of the Linux 7.2-rc3 release is predominantly made up of hardening the Realtek RTL8723BS WiFi driver. In particular, a number of fixes for addressing out-of-bounds behavior when connecting to "bad" WiFi hosts.

Debian 13.6 is out today as the newest point release of Debian Trixie to ship the latest security fixes and other maintenance updates.

Sent out today was this week's round of x86 (x86_64) fixes ahead of the Linux 7.2-rc3 kernel test candidate due out on Sunday.

Stanford researchers have been developing Lightweight Fault Isolation "LFI" compiler passes and targets for LLVM as a means of efficient, native code sandboxing. The AArch64 LFI target was previously upstreamed while this week the x86/x86_64 LFI target was also upstreamed for this means of in-process sandboxing.

KDE developers continue to be very busy this summer landing more features for the upcoming Plasma 6.8 desktop.

A change upstreamed to Mesa by an Arm engineer now enables the Panfrost Gallium3D driver for Arm Mali graphics to work with the Rusticl driver by default.

Wine 11.13 is out today as the newest bi-weekly development release for this open-source software enabling support for running Windows games and applications on Linux.

System76 developers have for the past number of weeks been working on developing a "frosted glass" appearance for the COSMIC desktop environment featured on their Pop!_OS Linux distribution. For Pop!_OS users this frosted glass feature is now available and will become more widespread for other Linux distributions once the next COSMIC release is formally tagged.

With KDE Plasma 6.7 now having seen a few point releases to further polish this last version with X11 support ahead of Plasma 6.8 going Wayland-only, here are some NVIDIA Linux gaming benchmarks between the X11 and Wayland sessions on Plasma 6.7.2 using the popular Arch Linux based CachyOS.
