[edk2-devel] [OVMF] Using EFI_TIMESTAMP_PROTOCOL in OVMF

[Ayush Singh]

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
