Intel TDX Support For KVM Finally Expected To Debut In Mainline Linux 6.16
While the Linux 6.15 merge window ended just one week ago and there is a month and a half until it will debut as stable, a notable feature has already been queued into a 'next' branch for the follow-on Linux 6.16 cycle
Bonzini explains in that merge message:"This large commit contains the initial support for TDX in KVM. These correspond to the usual KVM_EXIT_* "heavyweight vmexits" but are triggered through a different mechanism, similar to VMGEXIT for SEV-ES and SEV-SNP. - Loose ends: handling of the remaining exits from the TDX module, including EPT violation/misconfig and several TDVMCALL leaves that are handled in the kernel (CPUID, HLT, RDMSR/WRMSR, GetTdVmCallInfo); plus returning an error or ignoring operations that are not supported by TDX guests"
