Linux 7.3 To Overcome "Significant Bottleneck" For Small I/O With PCIe Gen5 NVMe SSDs

While the Linux 7.2 feature merge window ended just days ago and the better part of two months now before v7.2 will be released as stable, there are already features beginning to accumulate that will target the Linux 7.3 cycle. The most exciting change I've seen to kick off that dance ahead of Linux 7.3 is addressing a "significant" bottleneck affecting small direct I/O performance with speedy storage such as PCIe Gen5 NVMe SSDs...

AMD Sends Out Latest Linux Patches For RMPOPT Optimization

ASUS ROG Strix Laptop Sees Driver Fix For Linux Performance Too Low Compared To Windows

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...

Fedora 45 Looks To Finally Offer Install Support For Stratis Storage

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...

New Linux Driver Posted To Enable Keyboard Support On M3 MacBooks

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...
