Hi, This patch improves timer/clock for win32. Here is the patch and a binary.
http://www.h7.dion.ne.jp/~qemu-win/download/qemu-20060330-timer.patch http://www.h6.dion.ne.jp/~kazuw/qemu-win/qemu-20060330-timer.zip It supports 1ms interval interrupt. It also improves the delay when it is used with Kqemu/Qvm86. A main reason of delay of time is that when main_loop_wait is slept and an interrupt timer is expired, the timer interrupt doesn't occured. I used an event object to wake up the main loop. I used QueryPerformanceCounter/QueryPerformanceFrequency to measure time. It uses ACPI PM Timer on my system. Some system use RDTSC value. It depends on your system. It might be possible to run on SMP(HT or Multi-core) system. I haven't tested it, though.
