Hi, the following is stuff from qemu-xp and cannot directly be applied to the qemu sources. Anyhow: you can see what I have done. As a result windows displays the correct time. Also the poll() was a bit optimised. The timer stuff was changed to get some cpu cycles back. On a system with low CPU load the timer might consume 0.5% of the time, but under heavy CPU load you might see 5% time spent by the timer (actually I plan to dynamically reduce the alarm timer frequency in future versions). Other clean-ups are (and will be) related to memory-locality of frequently used data.
I have not seen any negative side effects of my code. TCP/IP still works (they use the cpu-clock-counter?). The code was not written for gamers... fast animations will not run precise. The deal is: don't waste cpu cycles but make the windows clock go right (even with speed-step). Yours Juergen
