Linux 7.1 Lands With Fresh NTFS Support, Intel FRED Defaults and Sweeping Legacy Cuts

Linus Torvalds shipped Linux 7.1 on schedule. He even pulled the trigger a half-day early to accommodate travel plans. The new kernel brings a production-ready in-kernel NTFS implementation. It enables Intel’s Flexible Return and Event Delivery by default. And it drops support for hardware that barely anyone still runs. The changes reflect years of accumulated technical debt meeting the realities of modern development flows.

Phoronix first detailed the release hours after the tag. Torvalds posted his announcement from abroad. “So it’s only Sunday morning back home, but it’s Sunday afternoon where I am right now, so I’m doing the 7.1 release at the regular time – just not in the regular timezone,” he wrote. The shortlog showed mostly small driver updates across graphics, networking, sound and miscellaneous areas. Nothing stood out as scary. That was the point.

Yet the cycle itself proved anything but routine. AI-generated bug reports flooded maintainers. The volume forced decisions on what code to keep. Wikipedia records the outcome in its version history table. Linux 7.1 adds a new NTFS driver formally known as NTFSPLUS. It removes legacy code including i486 support, some PCI and PCMCIA drivers, bus mouse code and more. The page also notes the Apple SMC power driver for battery information on Apple Silicon machines, Intel FRED enabled by default, real-time support on 32-bit ARM, a new Coreboot framebuffer driver, Intel QAT Zstd compression support and power reporting for AMD Ryzen AI NPUs.

The NTFS work stands as one of the most visible user-facing advances. For years Linux users relied on the aging NTFS-3G FUSE driver or an incomplete kernel implementation. The fresh driver promises faster operation and fuller feature parity with Windows drives. Tom’s Hardware covered the shift months earlier in an April preview. It described the change as the biggest under-the-radar storage update in years. Native treatment of Microsoft file systems removes a long-standing friction point for dual-boot users and those moving data across platforms.

Hardware enablement runs deep. Intel’s FRED technology improves exception handling and performance on Panther Lake processors and future chips. The kernel now turns it on by default. That decision delivers immediate gains for systems shipping later this year. AMD receives preparation for Zen 6, new SMCA bank types for EPYC Venice, and an SBI driver for the same platform. The AMDXDNA driver gains power estimate reporting for Ryzen AI NPUs. Older Radeon GPUs see driver improvements that extend their useful life.

Apple Silicon users gain something they have wanted for years. The Apple SMC power driver finally exposes battery metrics in mainline kernels. No more out-of-tree patches or incomplete data. Phoronix highlighted this addition in its comprehensive feature overview published in early May. The article cataloged nearly every meaningful addition across 40 million lines of code. It called the NTFS driver very significant. It pointed to incremental performance work throughout the tree.

Real-time support reaches 32-bit ARM. The mainline kernel can now build RT kernels for that architecture without external patches. AArch64 already enjoyed the capability. The change matters for embedded developers who target smaller cores. Experimental pKVM protected guests appear for KVM virtualization. A new Coreboot framebuffer driver joins the DRM subsystem. Intel’s QuickAssist Technology gains Zstd support alongside Gen6 hardware improvements. The x86_energy_perf_policy tool learns about Panther Lake SoCs.

But the story is not only about what arrived. Linux 7.1 aggressively prunes. Phoronix noted that AI-assisted bug reports drove many of the deletions. Obsolete hardware generated noise disproportionate to its usage. ISDN drivers, certain old network code, bus mouse support, select PCMCIA and PCI drivers all left the tree. The kernel begins to phase out i486. Build options disappear even if some code remains. UDP-Lite support retires. Russia’s Baikal CPU support starts its exit. These moves reduce maintenance burden. They also signal a sharper focus on 64-bit systems. Some merged changes may affect 32-bit users negatively. The project has made its priorities clear.

Torvalds expressed frustration during the cycle. In the rc5 announcement he remarked on the unusually large patch volume so late. “I’m really not convinced the churn is worth it at rc5 time,” he said according to Phoronix coverage of the release candidate. Many fixes came from AI coding tools. They were trivial. They touched rarely used drivers. He questioned whether they belonged in linux-next instead. The episode underscored a broader tension. Automated assistance accelerates contribution. It also floods the process with patches that require human review.

That tension shaped the final product. Code removals protected maintainers from endless low-value reports. Performance work continued in areas that matter. Workqueue improvements target CPUs with many cores per last-level cache. Idle SMT sibling handling benefits sched_ext users. The Intel Xe driver handles video memory pressure better and exposes a new user-space interface. AMDGPU DC now supports GCN 1.1 APUs by default. Sea Islands parts move away from the legacy Radeon driver.

LoongArch receives HIGHMEM support. Arm gains a workaround for the C1-Pro processor erratum. Twelve new SoCs and platforms across ARM and RISC-V join the supported list. x86 aligns its custom restart handler behavior with other architectures. Linear Address Space Separation on Intel is deemed production ready. These details rarely make headlines. They matter to the engineers who deploy Linux at scale.

Distributions will begin picking up 7.1 in the coming weeks. Some have already landed it in testing repositories. SparkyLinux moved the kernel into its repos on release day. Users running bleeding-edge desktops or servers will see the NTFS improvements first. Enterprise deployments will watch the real-time ARM support and the hardware enablement for upcoming Intel and AMD silicon. The legacy removals should pass unnoticed for most. That is the goal.

Torvalds noted possible irregularities in the 7.2 merge window. Long flights without internet and shifting time zones will complicate his usual front-loaded approach. He has already pulled early requests. The work continues. Linux 7.1 closes one chapter. The next merge window opens immediately. And the cycle repeats. Faster graphics for Intel’s Battlemage. Better power reporting on AI accelerators. A file system that no longer feels like a second-class citizen. These gains accumulate. They keep the kernel relevant on everything from smartphones to supercomputers.

One fact stands out. The kernel reached this point despite an unprecedented wave of machine-generated noise. Maintainers adapted. They cut what no longer paid its way. They accepted patches that moved the platform forward. The result ships today. It looks like a normal kernel release. The story behind it reveals how development itself is changing.
