# Motivation This PR intends to reland #134666 that has been reverted in #140872 We reverted it because I forgot to support `elapsed_time` for `XPUGuardImpl`, which resulted in `c10::Event` not supporting' elapsed_time' and blocking XPU CI. # Additional Context We split #134666 into two parts: one part, PR #140865, supports `elapsed_time` for `torch.Event` and another one, this PR, supports for `torch.xpu.elapsed_time`.
