Partition Reference TSC Mechanism

The partition reference time is computed by the following formula:

Copy 

ReferenceTime = ((VirtualTsc * TscScale) >> 64) + TscOffset

The multiplication is a 64 bit multiplication, which results in a 128 bit number. This 128 bit number is then shifted 64 times to the right to obtain the high 64 bits.
