KVM will need to read bunch of TDX module metadata fields to create and run TDX guests. In the long term, other in-kernel TDX users, e.g., VT-d also likely will need to read metadata. This series provides common APIs in the TDX host code so that KVM can use. This series has been sent out together with the v19 KVM TDX patchset, and actually received one minor comment from Juergen [1](thanks!), which I fixed in this series. Now I am sending out this series separately to reduce the size of the KVM TDX patchset. Paolo and Sean are doing similar things [2][3].
