KVM TDX: TDP MMU: large page support is already supported in this 24.04 release, do you mean this feature?

[Ruomeng Hao]

Yes, I mean transparent hugepage for TD. Any additional parameters are required to use it?

[fanchen2]

Yes, we included this patchset https://lore.kernel.org/all/[e-mail]/#r
It is enabled by default, but please pay attention to the release note, guest memory need to be 2M aligned, or it will not be enabled, no additional para needed.
