πŸ“¦ version 7.3.1, in nixpkgs unstable

✨ NAME ✨

okay bestie, this is the efi_secret page from the Kernel API Manual, section 9, and the manual-name moment is literally: Allow reading EFI confidential computing (coco) secret area via securityfs interface. πŸ’–

πŸ¦‹ DESCRIPTION πŸ¦‹

When the module is loaded (and securityfs is mounted, typically under /sys/kernel/security), a "secrets/coco" directory is created in securityfs. πŸŽ€

Inside it, a file is created for each secret entry. The name of each such file is the GUID of the secret entry, and its content is the secret data. 🌸

πŸ’… SEE ALSO πŸ’…

  • struct secret_header(9) β€” struct reference, no cap. πŸ¦‹
  • struct secret_entry(9) β€” the other struct reference, periodt. ⭐

That’s the whole read, bestie: source/version ./drivers/virt/coco/efi_secret, dated October 2026, with footer title energy efi_secret:... secret area(9). 🫢✨
