| message |
Add TSC synchronization for multiprocessor machines. CPU0 is the reference clock and all others are skewed. During CPU initialization the clocks synchronize by keeping a registry of each CPU clock skewness and adapting the TSC read routine accordingly. This commit also re-enables TSC as the default time source. Future work includes MSR-based synchronization via IA32_TSC_ADJUST and perhaps adding a task that is executed periodically to keep the clocks in sync in case they drift apart. Inspired from NetBSD. Tested by many and thoroughly reviewed by kettenis@, thank you! OK kettenis@, deraadt@ |
