Hello, all. In my automated tests I found out that on ARM64-EFI sleep 10 actually sleeps for 100s. The culprit is that EFI doesn't call our timer every 1ms but every 10ms. I propose time1.diff to correct: request EFI to call us every 10ms and increment timer variable by 10. For arm64 I propose to use CPU timer instead time2.diff. Can any of ARM guys comment on this?
