OvmfPkgX64.dsc can run in SEV/TDX modes too, so it is needed there as well. We can probably leave it out from IntelTdx (assuming Intel's upstream merge plans work out as expected and tdx-guest + unaccepted memory actually land in the same kernel release). take care, Gerd -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
