From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This is the best summary I could come up with:
The Kernel-based Virtual Machine changes for Linux 6.9 continue to enhance the capabilities of the open-source Linux virtualization software stack.
Developers found this provides a nice approximate 10% performance improvement for VM-Exit micro-benchmarks.
The KVM x86 Xen emulation code has also seen some improvements for Linux 6.9.
Another change worth noting from the KVM pull request is AMD now reports a "ept_5level" flag in /proc/cpuinfo for VMX supporting 5-level EPT paging.
Over on the KVM RISC-V side is support for the Ztso and Zacas extensions.
More details on the KVM changes for Linux 6.9 via this pull that was already merged.
