[PATCH 6/8] x86/tsc: Always Running Timer (ART) correlated clocksource

2016-03-03 Thread John Stultz
From: "Christopher S. Hall" On modern Intel systems TSC is derived from the new Always Running Timer (ART). ART can be captured simultaneous to the capture of audio and network device clocks, allowing a correlation between timebases to be constructed. Upon capture,
