Workflow for Issuing SEAMCALLs #255

Open pansilup opened 4 hours ago

pansilup commented 4 hours ago

Hi there, I'm looking for some information on the workflow of issuing SEAMCALLs and have some basic questions. Can I check if TDX enlightened KVM has opened up new TDX specific ioctls for user space (e.g., QEMU) to initiate/issue SEAMCALLs as part of TDX-Env/TD management? For instance, 1.Who is supposed to call "tdx_enable()" in https://github.com/torvalds/linux/blob/ae90f6a6170d7a7a1aa4fddf664fbd093e3023bc/arch/x86/virt/vmx/tdx/tdx.c#L1215 2.How does a SEAMCALLs (such as TDH_MNG_CREATE) request arrive at https://github.com/torvalds/linux/blob/ae90f6a6170d7a7a1aa4fddf664fbd093e3023bc/arch/x86/virt/vmx/tdx/seamcall.S#L21 Any information or documentation on this would be greatly appreciated.
