On June 28, 2026, Linus Torvalds released Linux 7.2-rc1, closing a two-week merge window that pulled in thousands of patches from developers around the world. The first release candidate for Linux 7.2 ushers in a testing cycle that will last several weeks, culminating in a stable kernel likely by mid-August. This initial snapshot previews a raft of changes that touch everything from cutting-edge AMD graphics hardware to the low-level scheduling algorithms that govern CPU resource allocation. For Windows users and power users who straddle both operating systems, the updates to NTFS compatibility are a standout, promising smoother file sharing and dual-boot reliability.
Linux 7.2-rc1 is not just an incremental update. It bundles major GPU driver work, a new image signal processor framework, cache topology-aware scheduling, and long-awaited NTFS filesystem fixes. The merge window, which opened on June 14, saw fierce deliberation over some submissions, but Torvalds gave the final code his blessing, noting in the mailing list announcement that the changes were “substantial but well-contained.” With this release candidate, Linux enthusiasts and kernel testers can now put the new code through its paces.
The kernel’s graphics subsystem receives star billing. AMD’s amdgpu driver adds support for HDMI 2.1 Fixed Rate Link (FRL), a technology that replaces the older TMDS signaling to enable uncompressed 4K at 120 Hz, 8K at 60 Hz, and dynamic HDR over standard HDMI cables. This brings the Linux open-source driver in line with the capabilities of modern AMD RDNA 4 GPUs, which natively support HDMI 2.1 outputs. The implementation in 7.2-rc1 finally exposes the full bandwidth and feature set that gamers, content creators, and multimedia enthusiasts have been demanding. Additionally, the driver introduces support for AMD’s ISP4, the fourth-generation Image Signal Processor that will debut in upcoming Ryzen systems-on-chip. ISP4 handles camera image processing, including noise reduction, HDR stitching, and auto-focus, directly in hardware. Having this framework in the mainline kernel means that Linux distributions will be able to tap into laptop and mini-PC cameras with far greater fidelity and lower power consumption. Early adopters report that the ISP4 code still requires accompanying firmware, but the foundation is now in place.
Beyond graphics, the kernel incorporates cache-aware scheduling improvements that directly address the heterogeneous nature of modern CPUs. While much of the early scheduler work for big.LITTLE-style architectures focused on Intel’s hybrid P-core/E-core designs, AMD’s upcoming processors also adopt mixed core clusters with varying cache sizes. The new code in the Completely Fair Scheduler (CFS) considers the cache topology of the CPU, aiming to place tasks on cores that share the most cache with the tasks’ memory footprint. This reduces cache misses and cross-core data migration, boosting throughput for database workloads, compiling, and VM hosting. In benchmarks shared by kernel developers, the patchset yields a 4-7% performance uplift on some synthetic workloads, with real-world gains visible in build times and server response latencies.
The NTFS filesystem driver, NTFS3, receives a noteworthy batch of fixes. Maintained by Paragon Software, NTFS3 has been the default NTFS implementation in the Linux kernel since version 5.15. It offers near-native performance and support for advanced features like compression, encryption, and reparse points. However, users have occasionally encountered data corruption when writing large files, mount failures after improper Windows shutdowns, and issues with case-sensitive directories. Linux 7.2-rc1 rolls up fixes for these pain points, including improved journal handling, better synchronization with Windows’ fast startup mode, and corrected handling of extended attributes. Many of these patches were backported from Paragon’s commercial driver after extensive testing. For those who regularly share external SSDs or dual-boot between Linux and Windows, the enhanced NTFS3 reliability is a significant quality-of-life improvement.
Other notable additions in 7.2-rc1 include updated drivers for Intel’s Battlemage discrete GPUs, initial support for some Qualcomm Snapdragon X Elite ARM laptops, and various security hardening measures. The Btrfs filesystem sees performance optimizations for fsync-heavy workloads, and there are new io_uring operations that reduce overhead for network applications. The kernel also picks up support for a handful of new peripheral devices, such as Sony’s upcoming VR controllers and a new class of haptic feedback hardware.
From a Windows user’s perspective, the NTFS fixes are the most immediately impactful. As Windows 11 increasingly relies on NTFS for everything from gaming to development containers, having a rock-solid Linux NTFS driver ensures that data integrity does not become a gamble when switching operating systems. Even users who never boot Linux directly benefit indirectly: network-attached storage devices, Android-based media players, and even some routers run Linux kernels and may expose NTFS drives. With 7.2-rc1, those devices will be less likely to corrupt data.
The AMD HDMI 2.1 FRL support also matters for Windows users who want to tinker with Linux gaming. SteamOS, Valve’s Linux-based operating system for the Steam Deck and upcoming hardware, relies on the mainline amdgpu driver. Having FRL enabled means that when future AMD-powered Steam Decks or even desktop gaming rigs boot into Linux, they will fully leverage high-refresh-rate displays and variable refresh rate technologies without compromising signal quality.
Cache-aware scheduling, while a more esoteric kernel feature, has indirect consequences for Windows. As Microsoft continues to evolve its own scheduler for Windows 11 and Windows Server, it often cross-references Linux kernel innovations. The cache-topology work in 7.2-rc1 may influence future Windows scheduling algorithms, especially as both operating systems face the challenge of extracting maximum performance from increasingly complex chip architectures. Enterprise users running Linux virtual machines on Hyper-V will also feel the benefit, as the improved scheduler makes better use of virtualized CPU topologies.
Testing of 7.2-rc1 has already uncovered some minor regressions in sound drivers and a build failure on certain ARM configurations, but Torvalds noted that the overall volume of changes was manageable. He encouraged testers to focus on the amdgpu, scheduler, and NTFS patches in particular. The release candidate cycle is expected to last eight weeks, with 7.2-rc2 slated for July 5, and a stable release projected for August 23.
In the broader ecosystem, distribution maintainers are watching closely. Ubuntu, Fedora, and Arch Linux will likely ship Linux 7.2 in their fall releases, while enterprise distributions like Red Hat Enterprise Linux and SUSE Linux Enterprise will follow with backported subsets. The HDMI 2.1 and ISP4 code may prompt a flurry of kernel module rebuilds for users of the proprietary AMDGPU-PRO driver, though the open-source stack already covers most use cases.
The combination of enhanced display, camera, and filesystem support, wrapped in a smarter scheduler, makes Linux 7.2-rc1 a compelling preview. For the first time, Linux gains the same level of hardware support for AMD’s latest multimedia silicon as its Windows counterparts. The NTFS improvements chip away at one of the last lingering interoperability rough edges. As the testing cycle progresses, the community will uncover and squash bugs, but the trajectory is clear: Linux 7.2 is shaping up to be a watershed release that tightens the bonds between the open-source kernel and the Microsoft ecosystem.
