      timers: Add CLOCK_BOOTTIME hrtimer base · 70a08cca
      John Stultz 提交于
      CLOCK_MONOTONIC stops while the system is in suspend. This is because
      to applications system suspend is invisible. However, there is a
      growing set of applications that are wanting to be suspend-aware,
      but do not want to deal with the complications of CLOCK_REALTIME
      (which might jump around if settimeofday is called).
      
      For these applications, I propose a new clockid: CLOCK_BOOTTIME.
      CLOCK_BOOTTIME is idential to CLOCK_MONOTONIC, except it also
      includes any time spent in suspend.
      
      This patch add hrtimer base for CLOCK_BOOTTIME, using
      get_monotonic_boottime/ktime_get_boottime, to allow
      in kernel users to set timers against.

      time: Introduce get_monotonic_boottime and ktime_get_boottime · abb3a4ea
      John Stultz 提交于
      This adds new functions that return the monotonic time since boot
      (in other words, CLOCK_MONOTONIC + suspend time).

      hrtimers: extend hrtimer base code to handle more then 2 clockids · e06383db
      John Stultz 提交于
      The hrtimer code is written mainly with CLOCK_REALTIME and CLOCK_MONOTONIC
      in mind. These are clockids 0 and 1 resepctively. However, if we are
      to introduce any new hrtimer bases, using new clockids, we have to skip
      the cputimers (clockids 2,3) as well as other clockids that may not impelement
      timers.
      
      This patch adds a little bit of indirection between the clockid and
      the base, so that we can extend the base by one when we add
      a new clockid at number 7 or so.
