Linus Torvalds heeft versie 7.2 van de Linux Kernel vrijgegeven. De kernel is het hart van het besturingssysteem en zit, simpel gezegd, als laag tussen de hardware en de applicaties in. De nieuwe uitgave bevat de gebruikelijke hoeveelheid aan veranderingen en verbeteringen. Meer informatie kan bij 9to5Linux, OMG Ubuntu en Phoronix worden gevonden.
Linux Kernel 7.2 Officially Released, This Is What’s NewHighlights of Linux 7.2 include cache-aware load-balancing support, initial HDMI 2.1 FRL support to the AMDGPU driver, support for devres-based management of ACPI notify handlers, initial CRI platform support for the Intel Xe driver, and Rust support for the IBM System/390 (S/390) architecture.
Linux kernel 7.2 also introduces a “Fair(er)” GPU scheduler, support for the ‘zerocopy’ library to Rust support to make zero-cost memory manipulation effortless, new hwcaps for the 2025 dpISA extensions on the AArch64 (ARM64) architecture, and enables large folios by default for the Btrfs file system.
It also brings Intel CPU model number support for Panther Lake R processor series, improvements to the kernel’s swap subsystem, support for multi-size transparent huge pages (mTHPs) to the khugepaged kernel thread, and support for compressed files to the SMB filesystem.
On top of that, Linux 7.2 improves the new NTFS filesystem introduced in Linux kernel 7.1, adds devicetree updates for 64-bit NXP/Freescale and Qualcomm platforms, introduces MPTCP signaling support for IPv6 addresses, adds GRO/GSO support for PPPoE, and brings more SMP load-balancing updates.
The EROFS file system received a fscache backend, the Ceph file system has gained the ability to reset clients manually, sched_ext gained initial support for sub-schedulers, the /proc/interrupts implementation has been updated for better performance, and the openat2() system call received a new O_EMPTYPATH flag.
Among other noteworthy changes, the XFS file system’s experimental zoned storage device support is no longer experimental, the dm-inlinecrypt device-mapper target received support for block devices, the TCP authentication option has been implemented, and there are also some Thunderbolt networking improvements.
Also worth mentioning is that the KVM subsystem has received support for AMD’s “guest-mode execution trap” and Intel’s “mode-based execution control” (MBEC) features, the NFS file system’s default block size was bumped to 4MB on systems with at least 16GB RAM, and support for the Intel Trusted Domain Extensions (TDX) feature has been added.
Security-wise, Linux kernel 7.2 brings the ability to control the use of UDP sockets to the Landlock module, the ability to stage measurement data outside of the kernel to the IMA (Integrity Measurement Architecture) subsystem, and support for compiler-assisted type-based slab cache partitioning to the slab allocator.
Last but not least, Linux 7.2 introduces the usual hardware support expansion through new and updated drivers. Worth mentioning, there’s PCI P2PDMA support for RAID0 and NVMe multipath, support for Intel Lizard Peak 2, support for TP-Link TL-UB250, and support for the HORI HORIPAD Nintendo Switch wireless controller.
