# SPDX-License-Identifier: GPL-2.0-only config EFI_SECRET tristate "EFI secret area securityfs support" depends on EFI && X86_64 select EFI_COCO_SECRET select SECURITYFS help This is a driver for accessing the EFI secret area via securityfs. The EFI secret area is a memory area designated by the firmware for confidential computing secret injection (for example for AMD SEV guests). The driver exposes the secrets as files in <securityfs>/secrets/coco. Files can be read and deleted (deleting a file wipes the secret from memory). To compile this driver as a module, choose M here. The module will be called efi_secret.
