[Qemu-devel] [RFC PATCH 0/5] allow arbitrary scaling of timers

[Paolo Bonzini <pbonzini@redhat.com>]

Right now, rt_clock timers are limited to millisecond resolutions;
other clocks are limited to nanoseconds.  This patch series removes
the limitation.

In order to ease transition, new functions are provided with
explicit resolution (milli/nanosecond).  The old qemu_get_clock
is removed.  The old qemu_new_timer is grown a new argument to
specify the resolution.

Most of the patch series (patches 2/3) is mechanical (sed).

Paolo Bonzini (5):
  add more helper functions with explicit milli/nanosecond resolution
  change all rt_clock references to use millisecond resolution
    accessors
  change all other clock references to use nanosecond resolution
    accessors
  add a generic scaling mechanism for timers
  remove qemu_get_clock
