This allows for robust and correct behavior in cases of late or lost ticks, avoids interpolation errors, reduces duplication in arch specific code, and allows or assists future changes such as high-res timers, dynamic ticks, or realtime preemption. Additionally, it provides finer nanosecond resolution values to the clock_gettime functions. The patch set provides the minimal NTP changes, the clocksource abstraction, the core timekeeping code as well as the code to convert the i386 and x86-64 archs. I have started on converting more arches, but for now I'm focusing on i386 and x86-64. The current patchset can be found here: http://sr71.net/~jstultz/tod/ New in this release: x clock_was_set x x86-64 vsyscall fix suggested by Serge Belyshev. x dropped c3tsc for ACPI PM x dropped ACPI PM rate verification (causing false positives) Still on the TODO list: o nothing?
