* Introduce QEMU_CLOCK_HOSTJan Kiszka2009-10-051-0/+7
| | | | | | | | | | | | | | | | | | Despite its name QEMU_CLOCK_REALTIME is (normally) not using CLOCK_REALTIME / the host system time as base. In order to allow also non-trivial RTC emulations (MC146818) to follow the host time instead of the virtual guest time, introduce the new clock type QEMU_CLOCK_HOST. It is unconditionally based on CLOCK_REALTIME, thus will follow system time changes of the host. The only limitation of its current implementation is that pending host_clock timers may not fire early if the host time is pushed forward beyond their expiry. So far no urgent need to overcome this limitation was identified, so it's left as simple as it is (expiry on next alarm timer tick).

* Make get_ticks_per_sec() a static inlineAnthony Liguori2009-09-111-1/+4
| | | | | | | | | | | ticks_per_sec is a constant. There's no need to store it as a variable as it never changes since our time is based on units. Convert get_ticks_per_sec() to a static inline and move the constant into qemu-timer.h. Remove all references to QEMU_TIMER_BASE so that we consistently use this interface.

* variable timer intervalsStefano Stabellini2009-08-101-0/+1
| | | | | | | | | | | | | | This patch introduces dynamic timer intervals: we slow down the refresh rate when there in no much activity but we get back to a fast refresh rate when the activity resume. Please note that qemu_timer_expired is not an inline function any more because I needed to call it from vnc.c however I don't think this change should have any serious consequence.
