With the Linux 7.1 merge window winding down ahead of the planned Linux 7.1-rc1 release on Sunday, I have begun testing out the Linux 7.1 Git state on various systems in my lab. So far Linux 7.1 appears to be looking good in the performance department with seeing a number of performance improvements in different areas but also a few possible regressions.⇒ Farewell ISDN, Ham Radio & Old Network Drivers: Linus Torvalds Merges 138k L.O.C. Removal:
Linus Torvalds did it! He merged the pull request to rid the Linux kernel of the old Integrated Services Digital Network (ISDN) subsystem and various other old network drivers largely for PCMCIA era network adapters. This was the code suggested for removal given the recent influx of AI/LLM-generated bug reports against this dated code that likely has no active upstream users remaining...⇒ LoongArch Improvements Land In Linux 7.1:

⇒ Linux 7.1-rc2 Bringing Some More Improvements/Fixes For Older AMD GPUs
Merged on Friday ahead of the Linux 7.1-rc2 kernel release due out tomorrow were this week's batch of Direct Rendering Manager (DRM) kernel graphics / display / accelerator driver fixes...⇒ Linux 7.1 Fixes Audio For The Steam Deck OLED After Being Broken 2 Years On The Upstream Kernel:
It turns out the Steam Deck OLED gaming handheld has not had working audio support with the mainline (upstream) Linux kernel since a change in late 2023 that was merged for Linux 6.8. There was an AMD ASoC audio change that inadvertently broke audio support for the Steam Deck OLED handheld but not affecting the original LCD model. Valve's downstream Steam OS kernel has compensated for this known breakage and other distributions targeting the Steam Deck OLED have carried the patch, but now there is a proper solution upstream ahead of Linux 7.1-rc2...⇒ New NTFS Driver Sees More Fixes With Linux 7.1-rc2
One of the most prominent changes with the upcoming Linux 7.1 kernel release is the introduction of the new NTFS driver in the Linux 7.1 kernel. This new driver provides more features and better performance than the Paragon NTFS3 driver that's been in the kernel the past few years and far better off than the original NTFS read-only driver that previously was in the kernel and for which this new driver is based. Needless to say it's also a big improvement over the NTFS-3G user-space FUSE driver too... -
⇒ Intel Drivers With Mesa 26.2 Ready With Xe In Linux 7.1 To Better Handle vRAM Pressure
Merged to the Intel Xe kernel graphics driver with Linux 7.1 is an addition to improve the video RAM memory pressure or out-of-memory behavior for Intel graphics with dedicated video memory. Introduced is support for purgeable buffer objects via a new user-space API to provide usage hints for enhancing what is purged under vRAM pressure. Merged this week to Mesa 26.2-devel is support for the Intel Mesa drivers to make use of this new interface...⇒ Linux 7.1 Features: New NTFS Driver, New Intel + AMD Hardware, Performance Optimizations & Modernization
The Linux 7.1 development kernel that amounts to nearly 40 million lines has a lot of new features and changes in tow. While Linux 7.1 stable won't be out until mid-June, here is a look at the interesting changes coming with this next stable version of the Linux kernel. -

⇒ (06/04) Linux 7.1 + Mesa 26.1 Performance With The Radeon RX 9070 GRE, RX 9070 XT
With this week's launch day review of the AMD Radeon RX 9070 GRE, Ubuntu 26.04 with its Linux 7.0 and Mesa 26.0 default driver stack was used for testing. That choice was made since the Ubuntu 26.04 release is still fresh, the RDNA4-based RX 9070 GRE was working without issue there, and from other RDNA4 testing knowing there isn't much uplift from the in-development Linux 7.1 kernel or the current stable Mesa 26.1 OpenGL RadeonSI / Vulkan RADV drivers. But for those interested, here are those tests…

⇒ New NTFS Linux Driver Being Improved For Windows Native Symbolic Links
One of the exciting additions to the Linux 7.1 kernel is the introduction of the new NTFS file-system kernel driver. While in good shape already and proving advantageous over other NTFS open-source driver options, one of the initial limitations on it is around Windows native symbolic link handling but that is now in the process of being resolved.
