Hello everyone. I wanted to ask if there was a device/parameter to have
`EFI_TIMESTAMP_PROTOCOL` in OVMF.
I would like to use this protocol to provide monotonic time in Rust (and
fall back to platform-specific registers in case the protocol is absent).
However, in the default qemu configuration, there is no handle supporting
`EFI_TIMESTAMP_PROTOCOL`.
For more information on what I am trying to implement, see
`std::time::Instant` [1] and the PR comment [2].
Yours Sincerely
Ayush Singh
