Subject: [PATCH 0/2] efi: add support for seeding the kernel RNG from UEFI
Date: Thu, 6 Oct 2016 11:27:24 +0100 [thread overview]
Message-ID: <1475749646-10844-1-git-send-email-ard.biesheuvel@linaro.org> (raw)
This implements generic EFI core kernel code to seed the kernel entropy
pool from a Linux specific UEFI configuration table containing a random seed
supplied by the firmware. (#1)
In addition, it wires it up for ARM and arm64, by invoking the EFI_RNG_PROTOCOL
UEFI protocol from the stub, and populating such a UEFI config table using its
output.
How to wire this up for x86 is left as an exercise for the Intel developer.
