The Linux Kernel 6.0 officially drops, and now, it introduces an interesting new feature which is its support for AArch64 hardware architecture. This allows it to swap huge transparent pages without even needing to split them.
Linus Torvalds Himself Dropped the New Linux Kernel 6.0
The announcement regarding the launch of Linux 6.0 came from Linus Torvalds himself. The new version of Linux is reportedly going to be a major kernel within the series as it is expected to bring not just bug and security fixes but new features as well.
The new Linux 6.0 is expected to come with new features as well as improved hardware support. Some of these additions include the support for AArch64 hardware architecture, along with some others.
New Linux Kernel 6.0 Adds Support for Interesting New Architectures
The new kernel 6.0 of Linux will also be able to support PCI buses when it comes to the OpenRISC as well as LoongArch architectures. There will also be async buffered writes when the XFS and io_uring are being used.
To add, there will also be zero-copy network transmission support for the io_uring. With that, the new Linux kernel 6.0 is going to add "Zicbom" extension support to the RISC-V hardware architecture.
Other Support Additions Include CXL Memory Regions to be Generated and More
This allows it to manage devices along with non-cache-coherent DMA. Other inclusions will be a new runtime verification subsystem that would allow for kernel state monitoring as well as support for CXL memory regions to be generated.
According to the story by 9to5Linux, there will also be support for POSIX access control lists on OverlayFS filesystems to properly be implemented. Lastly, there will be the implementation of what was described as the "second generation of Btrfs "send protocol which supports large data as well as raw compressed extents being sent.
DAMON Mechanism Will Add New User-Space Memory Management Features
When it comes to the changes, these include the DAMON mechanism adding new user-space memory management features. There will also be support for the limiting NFSv4 server to just 1024 active clients, specifically at 1GB RAM.
There will reportedly also be support for the EXT4 file system to help not just fetch but also set UUIDs that are stored within a file system superblock. Other changes include notifying subsystem support in order for ignored events to be better controlled.
Other Additions Include Enablement for AMD RDNA3 and Support for Qualcomm Snapdragon 8xc Gen3 Among Others
There will also be support for different sleepable BPF programs that are attached directly to uprobes. Lastly, there will be new reports directly to the perf tool when it comes to lock contention tracepoints as well as in-kernel aggregation with BPF.
More details regarding the Linux kernel 6.0 can also be found in the article by Phoronix. The details include enablement for AMD RDNA3, Qualcomm Snapdragon 8xc Gen3 support, and other changes as well.
