Help text

Confidential Computing platforms (such as AMD SEV) allow the Guest Owner to securely inject secrets during guest VM launch. The secrets are placed in a designated EFI reserved memory area.

In order to use the secrets in the kernel, the location of the secret area (as published in the EFI config table) must be kept.

If you say Y here, the address of the EFI secret area will be kept for usage inside the kernel. This will allow the virt/coco/efi_secret module to access the secrets, which in turn allows userspace programs to access the injected secrets.
