A Dhrtimers.rst2 hrtimers - subsystem for high-resolution kernel timers
5 This patch introduces a new subsystem for high-resolution kernel timers.
9 back and forth trying to integrate high-resolution and high-precision
11 such high-resolution timer implementations in practice, we came to the
18 - the forced handling of low-resolution and high-resolution timers in
30 necessitate a more complex handling of high resolution timers, which
62 high-resolution timer subsystem as well.
100 high-resolution clocks, where we need separate pending and expired
104 high-resolution clocks though, it also simplifies the handling of
126 special nanosecond-resolution 64bit type: ktime_t.
