Debcow is an experimental implementation of deploying Debian packages on copy-on-write file-systems like Btrfs and Bcachefs. Debcow adapts DPKG to use reflinks for installing packages. With reflinking to the file contents from the Debian package archives rather than copying of files, it can lead to a dramatic speed-up of installing Debian packages: as much as 6x faster on CoW file-systems...

In this article is a look at how the Google Axion processor performance compares to the competing Amazon/AWS Graviton4 processor.

Earlier this year was a Fedora change proposal seeking to make KDE Plasma the default over GNOME for Fedora 42. A compromise of sorts has now been settled on with the Fedora Desktop Spin being promoted to an "Edition" status that will put it on the same level as the GNOME-based Fedora Workstation Edition...

With the AMD EPYC 9005 "Turin" testing over the past month since launch I have looked at how well the new EPYC Turin CPUs compete against Intel Xeon, how Turin Dense dominates in performance and power efficiency to AmpereOne at 192 cores, and the generational uplift from EPYC Genoa to Turin at the same core counts, among other Turin performance benchmark tests. Up for comparison today is a look at how the NVIDIA Grace CPU performance within the GH200 Superchip compares to the AMD EPYC Turin processors.

Sent out yesterday was an AMDGPU/AMDKFD kernel driver pull request with the last few feature additions and patches slated for the upcoming Linux 6.13 kernel merge window.

Linux I/O expert and block/IO_uring maintainer Jens Axboe of Meta has recently revisited his patches around uncached buffered I/O. Back in 2019 the "RWF_UNCACHED" effort was started by Axboe to address a throughput cliff in performance once the page cache fills up. That work faded away but Axboe recently took to crafting a set of fresh patches for implementing uncached buffered I/O and they are showing extremely promising results...

Typically in my launch-day Linux reviews of new AMD EPYC processors I try to include results both of the performance determinism (default) and power determinism modes available with these server processors since opting in to the power determinism mode can allow for additional performance uplift at the cost of slightly higher power costs. With the AMD EPYC 9575F / 9755 / 9965 benchmarks and review I didn't have a chance to complete all of the power determinism runs in time for that review, but for those curious about power vs. performance determinism modes with the 5th Gen AMD EPYC "Turin" processors, here is a side-by-side comparison.

Upstreamed at the start of the year was the Imagination PowerVR open-source DRM kernel driver for newer Imagination Rogue GPUs. That upstream kernel driver is now being extended to cover the Imagination BXS-4-64 MC1 GPU...

The initial Xe3 graphics driver support patches have been trickling in while the final drm-intel-next pull ahead of the Linux 6.13 merge window has readied support for actually being able to light up a display connected to Xe3 LPD graphics with Panther Lake...

The x86-simd-sort project from Intel has been an interesting open-source software effort for much faster number sorting by using AVX-512. There's been lightning fast number sorting with AVX-512 and AVX2 code paths also added to broaden the appeal in helping CPUs without AVX-512. Projects like Numpy have been making use of this library while today x86-simd-sort 6.0 was released and also comes a few days after PyTorch has begun using this library too...

Posted to the Linux kernel mailing list last week and now queued already via tip/tip.git's "x86/cpu" Git branch is support for a new AMD CPU feature we haven't heard about until now... ERAPS, the Enhanced Return Address Prediction Security...

To clear up the ever-growing stack of laptops, I recently bought a TOUPUWAN 30-Slot Laptop/Tablet Storage Cart. This laptop/tablet storage cart can accommodate 32 devices in total while slots for up to 30 laptops/tablets 16.3-inches in size. It does have built-in power strips as well to easily facilitate charging of the devices while securely stored away but for my purposes I was just looking for something to better organize the mess of laptops I only occasionally pull out when running new Linux laptop benchmarks.

Arch-based Manjaro Linux is working on Manjaro Data Donor "MDD" as a new data collection tool of its users. This is intended to succeed their former ping-based solution for user counting plus incorporate hardware/software data collection on users.
