Linux Hardware Reviews & Performance Benchmarks, Open-Source News

Google Antigravity with the Gemini 3.5 Flash model helped a Linux user sort out a situation where his laptop was taking around 36 seconds to boot the kernel, which shouldn't be the case for the high-end laptop with AMD Ryzen 9 processor and 32GB of RAM. It ended up being yet another case of device firmware issues, but now a Linux kernel patch is pending for working around the issue on the ASUS ROG Strix G16 G614 laptop while discussions are ongoing in getting the vendor to provide a proper firmware fix.

When going through the VFIO subsystem patches for the ongoing Linux 7.2 merge window, there isn't too much to get excited about for end users with these changes. But there is the first time mentioning "Blackwell-Next" enablement by NVIDIA for the Linux kernel.

KUnit as the unit testing framework for the Linux kernel and was inspired in part by Java's JUnit when originally conceived, is now finally able to output to the JUnit format for better interoperability with other CI systems and the like that standardize on that common format.

Interesting feature work for VMware virtualization on Linux now being pursued by Broadcom is to support zero-copy buffer sharing between the VM(s) and host hypervisor, which would equate to an efficiency and performance win.

Linux 7.2 has finally eliminated the strncpy API from the Linux kernel. The strncpy() function for copying up to a specified number of bytes has long been deprecated and after six years of work and hundreds of patches, no more users of the strncpy interface within the Linux kernel remained that it has now been eliminated.

20 June 07:19 AM EDT - Arm - More Performance

Merged for Linux 7.1 was ARMM64 NEON-accelerated CRC64-NVMe support for around 6x the performance out of that checksumming algorithm. The generic code had been a bottleneck in NVMe and other storage subsystem code of the Linux kernel with CRC64-NVMe being used to help verify against data corruption. Now for Linux 7.2, the NEON-accelerated code will also work for those still relying on 32-bit ARM.

The open-source world waited long enough for the GIMP 3.0 release that finally came last year with its GTK3 port and more, but for those with time on their hands this weekend and want to relive GIMP's past from long ago, GIMP 0.54 has been adapted for Flatpak to work on modern Linux desktops. What makes this version of GIMP from 1996 notable is that it was the last to use the Motif toolkit.

While the AppleTalk networking protocols were innovative when they first appeared for their plug-and-play capabilities, Apple itself ended their AppleTalk support back in 2009. Now 17 years later, the Linux kernel is ending AppleTalk support due to a recent surge of AI-generated patches.

Linux 7.2 continues seeing a fair amount of storage-related changes from file-systems to the block device code itself, software RAID, the wonderful IO_uring interface, and more. Here is some of the latest feature work that has been merged for Linux 7.2.

Since the release in May of Firefox 151, Mozilla has been relying on the zlib-rs library for Gzip compression/decompression. This subtle change to use this Rust-based Zlib implementation has yielded some performance benefits and better memory safety but also some headaches when dealing with Intel CPU bugs.

There is no shortage of different file-systems available for Linux. New file-systems continue to come about in the open-source world but ultimately many of them end up not being well maintained or having very limited users and not necessarily innovating enough to make them worthwhile over other alternatives. Given the continued increase in file-systems looking to get into the Linux kernel, such as FTRFS and VMUFAT being some of the most recent and then even having multiple NTFS drivers for Linux, there is now documentation in place to formally lay out criteria for new file-systems to be accepted.

It's been a while since there has been any Slackware news to pass along, but this week they've finally landed the KDE Plasma 6 desktop in this legendary Linux distribution.

Intel's open-source Compute Runtime stack for OpenCL and oneAPI Level Zero on their graphics processors has been bringing up Nova Lake support since January. With today's release of the Intel Compute Runtime 26.22.38646.4, the Nova Lake Xe3P support has matured to the state of it being advertised now as under an "early support" status.

A patch series merged for the Linux 7.2 kernel addresses a race condition that can occur when a container is exiting yielding "VFS: Busy inodes after unmount" messages and a possible user-after-free condition. But the patch series also goes further and delivers a very nice optimization to lower the container unmounting latency for environments with heavy I/O load.

Merged as part of the many VFS changes for Linux 7.2 is the new OPENAT2_REGULAR flag for the openat2 system call. This can be used to limit programs to only open regular file-systems and avoid accidentally or intentionally opening up device files or other non-conventional data files on the file-system.
