Subject: [PATCH 0/3] OVMF: support EFI_RNG_PROTOCOL without virtio-rng
Date: Thu, 10 Nov 2022 14:47:35 +0100 [thread overview]
Message-ID: <20221110134738.3798618-1-ardb@kernel.org> (raw)
Currently, we only expose EFI_RNG_PROTOCOL when running under QEMU if it
exposes a virtio-rng device. This means that generic EFI apps or
loaders have no access to an entropy source if this device is
unavailable, unless they implement their own arch-specific handling to
figure out whether any CPU instructions or monitor calls can be used
instead.
So let's wire those up as EFI_RNG_PROTOCOL implementations as well,
using the existing drivers and libraries.
First patch is a bugfix - Liming, mind if I merge that right away?
Thanks.
