Phoronix: Wayland Protocols 1.13 Introduces New Input Timestamp Protocol

Jonas Ådahl on Wednesday announced Wayland-Protocols 1.13, the collection of stable and unstable protocols to Wayland...

This new protocol is more ideal for latency measurements and other isolated use-cases where a higher degree of precision is useful.

Hrm, isolated use-cases like exploiting Spectre?

Seriously the entirety of the computer industry seems to be frantically eliminating high-resolution timers right now. This seems pretty bizzarre, especially without a must-have usecase driving it.

Yeah.. this seems very odd. But maybe they are thinking in the future, when new hardware don't suffer from speculation attacks.

Did Wayland nail setting cursor coordinates? I remember SDL had really hard time with it.

If it's to do with something the user's doing then it can't really be used to exploit Spectre though, can it?

If it's to do with something the user's doing then it can't really be used to exploit Spectre though, can it?

You can emulate an USB input device with an Arduino (or any half-decent Atmel microcontroller).

Or with a virtual device driver.

Yep, they must be thinking of the future... when people will understand relativity and computers will have altimeters that correct the clock for time dilation.

Don't feel feeble-minded though, the government morons who designed our GPS satellite system didn't understand relativity either. That's why outside consultants had to be called in to fix it.

Regarding the altimeters for correcting the clock for time dilation, we're almost there:
