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.
