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.
