HW timers in Linux ?

rans — Thu, 11 Jan 2018 10:56:43 GMT

Hello,

I checked in docs and code, but not too sure:

Is kernel support HW timers ?

Is it that hrtimer in kernel (or timer_create in userspace) use HW timers ?

Thank you,

Ran

Yes, of course, the kernel timer relies on some hardware timer.

Have a great day,

Any software-created timer relies on the system timer, that, in turns, relies on the hardware timer.
