KVM Enhancements Within The Linux 6.14 Kernel
Along with other Intel TDX changes and AMD SEV updates separately sent out for thei n-development Linux 6.14 kernel, there is the usual hearty batch of Kernel-based Virtual Machine (KVM) virtualization updates too. Some of the KVM changes that were merged during the nearly-over Linux 6.14 merge window include: - Removing a redundant TLB flush on AMD CPUs when the guest CR4.PGE changes.
- Overhauling of the KVM x86 CPUID feature infrastructure to track all vCPU capabilities. - Continued work around enabling Intel Trust Domain Extensions (TDX) virtual machines. - A rework of KVM handling around VM-Exits during event vectoring to bring better parity between VMX and SVM usage.
