Last month on Phoronix there were 294 original news articles and 18 Linux hardware reviews / multi-page benchmark articles. Beyond Phoronix.com turning 22 years old in June, there were also a lot of exciting Linux hardware and open-source software developments worth recapping.

With modern laptops, proper platform/WMI drivers are becoming more depended upon not only for supporting all typical functionality from keyboards to backlights and other handling, but also for achieving proper performance. For many laptop vendors, the Linux platform drivers are maintained by the open-source community and actual customers. The latest example of the challenges of the community-maintained support rather than from the vendor is with the ASUS ROG Strix G16 G614PR gaming laptop seeing inappropriate power values set in the open-source driver that were incorrect and led to lower power/performance than Windows.

NVIDIA engineers have been developing a new binary format for their GPU firmware images for use with the in-development, open-source Nova kernel driver. With this new TLV binary firmware format it aims to be easier to parse by their Rust-based driver code.

As the last planned article on Phoronix of Q2, here is a look back at what excited readers the most in the second quarter. There were 872 original news articles this quarter as well as 54 Linux hardware reviews / multi-page featured benchmark articles. Here is what excited readers the most over these past three months.

GraalVM, the advanced JDK focused on ahead-of-time (AOT) Native Image compilation and since last year began shifting focus to more non-Java languages like Python and JavaScript, is out with its newest community feature release. GraalVM Community Edition 25.1.3 is now available with some interesting changes in tow.

Ever since RHEL deprecated their short-lived Btrfs plans, Red Hat engineers over the past decade have been developing Stratis Storage as their storage management solution leveraging XFS, LUKS, DM, and their Rust-based daemon. While Stratis Storage has been available in Fedora Linux going all the way back to Fedora 28, until now there hasn't been the option of using it for the root file-system on new Fedora installations. Finally with Fedora 45 that may change.

While Linux 7.2 introduces the ability to boot on Apple M3 Macs, it's not yet remotely useful for end-users wanting to use an Apple Mac/MacBook as their daily system. As it stands now, the M3 Macs boot to a simple console and that's about it with the lack of proper GPU acceleration and functionality like the keyboard on MacBooks not working either. Posted to the kernel mailing list today was the new driver patches for enabling the internal keyboard on more recent Apple MacBooks.
