Software-update: Linux Kernel 7.3

Linus Torvalds heeft versie 7.3 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 7.3 Officially Released, This Is What’s New

Linux kernel 7.3 is now available for download, as announced today by Linus Torvalds himself, featuring enhanced hardware support, filesystem and networking improvements, security enhancements, new drivers, and many other changes.

Highlights of Linux 7.3 include a new sandboxing mechanism based on a pseudo-file system, Rust support for PowerPC systems, userfaultfd support for tracking the working set of virtual machine guest memory, SMB server support for Apple Time Machine, and full support for cgroup sub-schedulers.

Linux kernel 7.3 also adds a new cpuidle subsystem for s390 (IBM System z) architectures, support for data-attributes-only monitoring to the DAMON subsystem, support for alternative data streams to the NTFS3 file system, support for id-mapped mounts to the OverlayFS file system, and support for directory delegations to the NFS server.

On top of that, Linux 7.3 introduces per-share SMB3 encryption support, a new rv wakeup monitor, SMB Direct RDMA encryption support, support for the F2FS file system to dynamically remove partitions from a filesystem’s pool, support for using big TCP packets in UDP tunnels, as well as a new ioctl() command for the memory-allocation profiling feature.

Of course, there are numerous improvements too, for things like cgroup scheduling, VRAM management for low-end GPUs, Btrfs and EXT4 performance, FUSE io_uring performance, mounting of multiple filesystems from a single block device, allocation of CPU time when using group scheduling, and the swap subsystem.

Security-wise, Linux kernel 7.3 introduces a new sysctl knob for regulating access to the AF_ALG cryptographic API from user space, support for compressed policies in the AppArmor security module, tighter verification of signed BPF programs, and support for setting the “no new privileges” flag for the calling process in the Landlock security module.

Linux 7.3 also introduces the usual hardware support expansion through new and updated drivers, supporting things like Adreno A704 GPUs, AMD-based Barco graphics adapters, Intel UFS 4.0 HS-Gear5, Pioneer DJ DJM-S11, Zenbook A16 keyboard, Nuvoton MA35D1 microprocessor, Intel Starfire SoCs, and the new Steam Controller.

Many laptops received improvements for audio, networking, etc., including Acer Aspire A515-57, ASUS VivoBook M515DA/X515DAP, Huawei Matebook, Minisforum AI X1 Pro, Lenovo Legion Pro, Lenovo Yoga Pro 7 14ASP10, HP OmniBook X Flip 14, HP Pavilion 15-eh2xxx, HP Spectre x360 16-aa0xxx, HP EliteBook 6 G1a, HP ProBook 440 G5, and ThinkPad X1 Carbon 6th Gen.

Haha de betere vram management is in deze tijd zeer welkom. Is het ook nvidia? Of alleen amd/ intel?

Van omgubuntu:


If your AMD graphics card has a limited amount of video memory (VRAM), Linux 7.3 handles tight memory situations better thanks to a new approach to resource allocation.

Previously, if VRAM filled up while running multiple apps, the kernel allocated space on a first-come, first-served basis. If you opened, say, a game late, it could be forced off the card’s faster VRAM and into system RAM (GTT).

In Linux 7.3, the kernel can ‘evict’ other apps’ unprotected background data out of VRAM to make room for tasks with higher priority, like a game requesting protected memory.

Valve’s Natalie Vock did the work. In tests with Indiana Jones and the Great Circle, the change allowed the game to run well on an 8GB GPU even when the settings were adjusted to push memory needs towards 9GB of VRAM.

It’s only part of the work; further VRAM management changes are on the way in future kernel releases.

Je kunt de source-code om zelf de kernel te bouwen downloaden vanaf hier.

De steam controller van dit jaar werkte toch al op Linux? Ik begrijp niet helemaal wat kernel ondersteuning tevoegd, kan iemand dat uitleggen?
