An initial patch series sent back out in April proposed PCACHE as a persistent memory cache for block devices. PCACHE was born out of the CXL block device driver and brings some benefits over the likes of BCache and dm-writecache...

FreeBSD developers have been working a lot on their wireless/WiFi driver support in recent months as part of their broader initiative for improving their operating system support for laptops. While a lot of progress has been made on seeing more modern WiFi support and recent WiFi chipsets being enabled, it's still not complete and that puts FreeBSD 15 in a tough position. FreeBSD 15 is set to be released later this year and will likely declare their wireless support as "unstable" to allow time for making future breaking modifications...

Ubuntu Linux maker Canonical announced they will be sunsetting their Bazaar distributed revision control system code hosting with Launchpad. Git wins...

Last month I began the much anticipated AMD Strix Halo Linux benchmarking at Phoronix by testing the top-end Ryzen AI Max+ PRO 395 that features 16 cores / 32 threads and the very impressive Radeon 8060S integrated graphics. Coming in one step below that flagship Strix Halo SoC is the Ryzen AI Max (PRO) 390 with Radeon 8050S graphics. Coming out today on Phoronix - coincidentally timed for the 21st birthday of Phoronix.com - is the first benchmarks of the Ryzen AI Max PRO 390 along with the Radeon 8050S graphics.

For some very fun Linux benchmarking on this 21st anniversary of starting Phoronix is looking at the Ryzen AI Max (PRO) 390 Linux performance, the 12-core Strix Halo SoC with Radeon 8050S Graphics. While there have been various benchmarks of the AMD Ryzen AI Max+ (PRO) 395 in recent weeks on Phoronix and other publications, the other Ryzen AI Max "Strix Halo" SoCs haven't been as widely seen in the industry yet. The 12-core Ryzen AI Max PRO 390 was tested within another HP ZBook Ultra G1a for a very interesting look at the high-end/premium Linux laptop/workstation performance.

In addition to a number of new Rust abstractions in different Linux kernel subsystems, the main Rust infrastructure pull request was submitted and merged yesterday as we approach the end of the Linux 6.16 merge window...

Now ahead of the Linux 6.16-rc1 release coming on Sunday to cap off the merge window, a second round of Bcachefs enhancements and fixes were merged...

Phoronix has made it another year. Today marks 21 years since I started Phoronix.com with a focus on providing Linux hardware reviews. Linux hardware support is a night and day difference then to today as is the overall ecosystem with all the major hardware vendors these days having some -- often significant -- levels of interest in Linux support. No longer is it typically a worry of whether your mouse, 56K modem, WiFi adapter, or other basic peripherals working but most often just a matter of how well the performance is on Linux, whether there is LVFS/Fwupd firmware updating support, and if other non-show-stopping features are supported. We still haven't managed the "year of the Linux desktop" but it's been wild with Chrome OS and Android being based on Linux, Linux coming to dominate the server world, Linux being ubiquitous to cloud computing, and Valve revolutionizing the Linux gaming space...

Ubuntu developers have recently started a discussion over possibly splitting up the "linux-firmware" package into multiple sub-packages given the growing size of all the different firmware binaries needed to support the diverse range of hardware supported by the Linux kernel. It's nice in theory for helping to reduce the install footprint of Ubuntu Linux but in practice will be difficult to pull off without potentially risking the out-of-the-box hardware support on Ubuntu Linux...

One of the niftiest kernel innovations to be upstreamed into Linux over the past year was sched_ext for extensible scheduler behavior in allowing kernel schedulers to be implemented via BPF programs. Sched_ext can allow for interesting scheduler improvements with a variety of use-cases and showed much potential even before being upstreamed. The work on sched_ext isn't yet over though and yet more improvements landed for Linux 6.16...

While Intel opted against implementing Hyper Threading for their latest Arrow Lake and Lunar Lake processors, Simultaneous Multi-Threading (SMT) still proves very effective on the AMD side. Even though the top-end AMD Ryzen AI MAX "Strix Halo" SoCs provide 16 Zen 5 cores, the presence of SMT for 32 threads still proves worthwhile from both a performance and power efficiency perspective. Here is an on/off comparison for SMT with the flagship AMD Ryzen AI MAX+ PRO 395 within the HP ZBook Ultra G1a.

AMD compiler engineer Joseph Huber is the one who ported DOOM to run on GPUs atop ROCm + LLVM libc as part of taking standard C/C++ code to run on GPUs and more recently has also been pursuing Flang/Fortran support atop GPUs. The latest in this ongoing quest is implementing efficient malloc support for memory allocation support on GPUs via the LLVM libc library...

Valve engineer Pierre-Loup A. Griffais contributed ByoWave Proteus controller support to the Linux kernel. ByoWave Proteus are some modular controller designs that can be adapted based upon the needs of the gamer and even what title you may be playing at the moment. The triggers and buttons are all repositionable for a very customized controller experience. The only downside is the modular gaming controller kit retails for $299 USD, but at least now works off the mainline Linux kernel...
