Description
Real Time Stamp Counter. This register is the 64-bit secondary, or “real” time stamp
counter. This counter allows software to configure the TSC not to include SMM or DMM
time, and still have an accurate real time measurement that includes these times.
BC_CONFIG0_MSR (MSR 00001900h) contains configuration bits that determine if the
RTSC counts during Suspend mode. It always counts during SMM and DMM modes.
All bits in this register are writable, unlike the TSC that clears the upper DWORD to 0 on
writes.
Description
Real Time Stamp Counter Low DWORD. This field provides a synchronized snapshot
of the low DWORD of the RTSC register (MSR 00001910h).
Time Stamp Counter Low DWORD. This field provides a synchronized snapshot of the
low DWORD of the TSC register (MSR 00000010h).
