Generally, this disclosure provides systems, methods and computer readable media for correlation of OS and hardware events to provide a corrected trace sequence. A system may include a processor configured to receive an OS event at a first time, generate a first timestamp based on a first clock associated with the OS, buffer the OS event until a second time, and generate a second timestamp based on the first clock. The system may also include a trace generation circuit configured to receive the OS event from the processor after the second time and generate a third timestamp based on a second clock associated with the trace generation circuit. The system may further include a trace correction circuit configured to calculate a corrected timestamp for the OS event based on differences between the first, second and third timestamps and further based on the relative frequency between the first and second clocks.
