[PATCH 0/4] efi/libstub: Fall back to CC proto for measurement

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ard Biesheuvel <ardb@xxxxxxxxxx>

This is a follow-up to Kuppuswamy's series [0] to add TDX based
measurement of the initrd and command line to the EFI stub.

In view of time wrt the merge window, I've taken the liberty of applying
my review feedback to the code directly, rather than going back and
forth with the author to converge on something we can both agree on.
