I was wondering why dom0's dmesg reports slightly different Hz rates for Linux vs Xen. Several years ago, Linux changed various PIT rate constants from 11931780 to 11931782. (The precise value should be 11931781.8181...) Xen apparently never caught up. (But interestingly many non-x86 arch's in Linux never did either!) This briefly explains the difference and history. http://groups.google.com/group/openwatcom.users.c_cpp/msg/db10671e6f8e711f Since this constant is usually used in mul/div calculations, it may be possible to get even more precise: 105000000/88 Constant replacement patch attached. I may try to use the more precise calculation later as the exact value becomes more important for clocksource=tsc.
